ABSTRACT Purpose To evaluate the morphological and stereological parameters of the testicles in mice exposed to bisphenol S and/or high-fat diet-induced obesity. Material and Methods Forty adult male C57BL/6 mice were fed a standard diet (SC) or high-fat diet (HF) for a total of 12 weeks. The sample was randomly divided into 4 experimental groups with 10 mices as follows: a) SC - animals fed a standard diet; b) SC-B - animals fed a standard diet and administration of BPS (25 μg/kg of body mass/day) in drinking water; c) HF: animals fed a high-fat diet; d) HF-B - animals fed a high-fat diet and administration of BPS (25 μg/Kg of body mass/day) in drinking water. BPS administration lasted 12 weeks, following exposure to the SC and HF diets. BPS was diluted in absolute ethanol (0.1%) and added to drinking water (concentration of 25 μg/kg body weight/day). The animals were euthanized, and the testes were processed and stained with hematoxylin and eosin (H&E) for morphometric and stereological parameters, including density of seminiferous tubules per area, length density and total length of seminiferous tubules, height of the tunica albuginea and the diameter of the seminiferous tubules. The images were captured with an Olympus BX51 microscope and Olympus DP70 camera. The stereological analysis was done with the Image Pro and Image J programs. Means were statistically compared using ANOVA and the Holm-Sidak post-test (p<0.05). Results The seminiferous tubule density per area reduced in all groups when compared with SC samples (p<0.001): HF (40%), SC-B 3(2%), and HF-B (36%). Length density was reduced significantly (p<0.001) in all groups when compared with SC group: HF (40%), SC-B (32%), and HF-B (36%). The seminiferous tubule total length was reduced (p<0.001) when compared to f HF (28%) and SC-B (26%) groups. The tubule diameter increased significantly (p<0.001) only when we compared the SC group with SC (54%) an SC-B (25%) groups and the tunica thickness increased significantly only in HF group (117%) when compared with SC-B (20%) and HF-B 31%.

ABSTRACT Purpose Varicocele is a condition known to cause damage to seminal parameters and sperm function. Furthermore, it has been hypothesized that the varicocele effect on fertility is time-dependent; however, little is known about the consequences of its establishment time on reproductive organs and/or sperm function. This study aimed to evaluate the effect of the duration of experimental varicocele on reproductive organs, sperm parameters, and sperm function. Materials and Methods Varicocele induction surgeries were performed in Wistar rats aged 40 or 100 days old. At 160-day-old, analyses were performed, including biometry of reproductive organs (prostate, seminal vesicles, epididymis, and testis), sperm parameters (vitality, morphology, and motility), and sperm function tests (nuclear DNA integrity, acrosome integrity, and mitochondrial activity). Results The analysis of the biometry of reproductive organs showed no differences between distinct ages in which varicocele was induced. The total abnormal sperm morphology was bigger in animals with varicocele induced to 100 days old than in animals with varicocele induced to 40 days old. Regarding nuclear DNA integrity, animals of varicocele induced to 100 days old showed worse results compared to animals of varicocele induced to 40 days old. Other parameters analyzed showed no differences between varicocele groups. Conclusion In this study conducted on rats, we conclude that varicocele adversely affects sperm, particularly its function. However, we did not observe a negative progressive effect on sperm.

ABSTRACT In 2007 the Nordic group came to the following unanimous conclusions: In general, hormonal treatment is not recommended, considering the poor immediate results and the possible long-term adverse effects on spermatogenesis. Thus, surgery is to be preferred. However, defective mini puberty inducing insufficient gonadotropin secretion is one of the most common causes of nonobstructive azoospermia in men suffering from congenital isolated unilateral or bilateral cryptorchidism. The extent of alteration in the unilateral undescended testis correlate with the contralateral descended testis, indicating that unilateral cryptorchidism is a bilateral disease. Idiopathic central hypogonadism explains the phenomenon of defective mini puberty in otherwise healthy cryptorchid boys. We therefore recommend hormonal treatment for cryptorchid boys with defective mini puberty. Gonadotropin releasing hormone agonist (GnRHa) treatment following surgery to correct cryptorchidism restores mini puberty via endocrinological and transcriptional effects and prevents adult infertility in most cases. Several genes are important for central hypogonadotropic hypogonadism in mammals, including many that are transcribed in both the brain and testis. At the molecular level, there is no convincing evidence that heat shock is responsible for the observed pathological testicular changes. Thus, impaired transformation of gonocytes is not the result of temperature stress but rather a hormonal imbalance. Cryptorchidism should therefore be considered a serious andrological problem that cannot be successfully treated by early orchidopexy alone. 200 conclusions general recommended longterm long term spermatogenesis Thus preferred However disease GnRHa (GnRHa cases mammals level changes imbalance alone 20 2

Abstract The present study aimed to produce a monosex population of all male Nile tilapia (Oreochromis spp.) using 17α-methyl testosterone and common carp testes (as a source of natural androgen). Trial was conducted into two consecutive phases, the first was fry (4-5 days old)administration with negative control (without hormone) and positive control (with hormone) feed viz., MT1:60mg/kg, MT2:70mg/kg (17α-MT), carp testis CT1:70% and CT2:80% for 30 days to reverse the sex of male fish and the second phase was nursing the fingerlings for two months on control diet (32% Crude protein).Results revealed a significant growth rate (P<0.05) in the control group where final weight (4.8±0.34ab) and weight gained was recorded as 0.66±0.03ac. In proximate chemical composition of body meat, CT2 treatment showed maximum retention of crude protein, crude fat, and ash whereas dry matter showed maximum retention in MT2 and CT1 treatments. Morphological and histological examination revealed significant difference (p<0.05) in phenotypic males of Nile tilapia fed with the highest percent in MT-treated diet (MT2) of 95±0.58a while MT1, CT2 and CT1 had males of 85±6.0b, 70±5.0b and 65±6.5b, respectively. It was concluded that synthetic androgen (17αMT) was more effective for masculinization but natural androgen scan be an alternative method to produce male tilapia population in an environment-friendly manner as they are inexpensive, eco-friendly, and radially available. These results suggested that synthetic and natural androgen supplementation in the diet plays a significant role in improving growth performance and body composition.

Resumo O presente estudo teve como objetivo produzir uma população monossexuada de todos os machos de tilápia do Nilo (Oreochromis spp.) usando 17α-metil testosterona e testículos de carpa comum como fonte de andrógeno natural. O ensaio foi conduzido em duas fases consecutivas, a primeira foi a administração de alevinos (4-5 dias) com controle negativo (sem hormônio) e controle positivo (com hormônio), viz., MT1:60mg/kg, MT2:70mg/kg (17α -MT), testículos de carpa CT1:70% e CT2:80% por 30 dias para inverter o sexo dos peixes machos e a segunda fase foi amamentar os alevinos por dois meses com dieta controle (32% de proteína bruta), e analisar a taxa de crescimento (p < 0,05) no grupo controle, em que o peso final (4,8 ± 0,34 ab) e o peso ganho foram registrados como 0,66 ± 0,03 ac. Na composição química aproximada da carne corporal, o tratamento CT2 mostrou retenção máxima de proteína bruta, gordura bruta e cinzas, enquanto a matéria seca apresentou retenção máxima nos tratamentos MT2 e CT1. O exame morfológico e histológico revelou diferença significativa (p < 0,05) nos machos fenotípicos de tilápia do Nilo alimentados com o maior percentual na dieta tratada com MT (MT2) de 95 ± 0,58a enquanto MT1, CT2 e CT1 tiveram machos de 85 ± 6,0b, 70 ± 5,0 e 65 ± 6,5b, respectivamente. Concluiu-se que o andrógeno sintético (17αMT) foi mais eficaz para a masculinização, entretanto os andrógenos naturais podem ser um método alternativo para produzir população de tilápias machos de maneira ecológica, pois são baratos, ecológicos e estão disponíveis radialmente. Esses resultados sugerem que a suplementação de andrógenos sintéticos e naturais na dieta desempenha um papel significativo na melhoria do desempenho do crescimento e da composição corporal.

ABSTRACT. The aim of this study was to investigate the effectiveness of intratesticular injection (ITI) of sodium chloride (NaCl) at two different concentrations for supressing reproductive development in goat kids at two months of age. The experiment was carried out at the experimental unit of Aydın Adnan Menderes University, Çine Vocational School, located in Çine, Aydın, Turkey. The experimental groups were control (C, n = 9), a single ITI of 20% NaCl (T1, n = 8) or 40% NaCl (T2, n = 8). The growth, reproductive characteristics, and histological appearance of the testis in the kids were examined up to nine months of age in different periods. The live weights, scrotal circumference, semen and sexual behavior characteristics were not different among groups. The histogical findings were observed in both testes at nine months of age. Greater intensity of destruction was observed in the testes of T1 and T2 kids than that of C kids. High levels of tubular degeneration were detected in testicular tissue samples in T1 and T2 groups. Based on the results, however, it was concluded that neither 20 nor 40% concentrations of NaCl did ensure the castration effect in the goat kids.

Abstract The elemental status of cattle is one of the important factors, which determine its growth, fertility, fetal development, meat and dairy production, etc. Therefore, the study of content of different elements in cattle organs and tissues and its correlation with cattle characteristics and diet is urgent task. It is also important to develop intravital and low-invasive methods to analyze element content in cattle to regulate its diet during lifetime. In the present work, we have studied the content and distribution of manganese in Hereford cattle from an ecologically clean zone of Western Siberia (Russia). 252 samples were taken from 31 bulls aged 15-18 months. They were collected from various livestock farms in the region and analyzed using atomic absorption spectrophotometry (organs and muscle tissue) and inductively coupled plasma atomic emission spectrometry (hair). The median values of manganese concentration obtained in natural moisture for hair, heart, kidneys, liver, lungs, muscles, spleen, testes, and brain were 25, 0.37, 1.0, 2.6, 0.4, 0.2, 0.4, 0.5, and 0.5 ppm. Accordingly, the concentration of manganese differs significantly in the organs and tissues of animals (H = 188.6, df = 8, p <0.0001). Statistically significant associations of manganese were revealed in pairs: liver-testis, hair-testis, spleen-testis, and heart-brain. The classification of organs and tissues of animals according to the level of content and variability of manganese is carried out. The concentration of manganese in the body is not uniform, most of all it is deposited in the hair and excretory organs of the liver and kidneys. In other organs and muscle tissues, the distribution of manganese is more even and is in the range of 0.2-0.5 ppm. The resulting ranges can be used as a guideline for Hereford cattle bred in Western Siberia. factors growth fertility development production etc Therefore task lowinvasive low invasive lifetime work Russia.

Resumo O status elementar do gado é um dos fatores importantes que determinam seu crescimento, fertilidade, desenvolvimento fetal, produção de carne e laticínios, etc. Portanto, o estudo do conteúdo de diferentes elementos nos órgãos e tecidos do gado e sua correlação com as características do gado e dieta é tarefa urgente. Também é importante desenvolver métodos intravitais e pouco invasivos para analisar o conteúdo de elementos em bovinos para regular sua dieta durante a vida. No presente trabalho, estudamos o conteúdo e a distribuição de manganês em gado Hereford de uma zona ecologicamente limpa da Sibéria Ocidental (Rússia). Foram coletadas 252 amostras de 31 touros com idade entre 15 e 18 meses. Eles foram coletados em diversas fazendas pecuárias da região e analisados por espectrofotometria de absorção atômica (órgãos e tecido muscular) e espectrometria de emissão atômica com plasma indutivamente acoplado (cabelo). Os valores medianos da concentração de manganês obtidos na umidade natural para cabelo, coração, rins, fígado, pulmões, músculos, baço, testículos e cérebro foram 25, 0,37, 1,0, 2,6, 0,4, 0,2, 0,4, 0,5 e 0,5 ppm. Assim, a concentração de manganês difere significativamente nos órgãos e tecidos dos animais (H = 188,6, df = 8, p <0,0001). Associações estatisticamente significativas de manganês foram reveladas em pares: fígado-testículo, cabelo-testículo, baço-testículo e coração-cérebro. É realizada a classificação dos órgãos e tecidos dos animais de acordo com o nível de conteúdo e variabilidade do manganês. A concentração de manganês no corpo não é uniforme, sendo principalmente depositada nos cabelos e nos órgãos excretores do fígado e dos rins. Em outros órgãos e tecidos musculares, a distribuição do manganês é mais uniforme e fica na faixa de 0,2-0,5 ppm.

Abstract In 2015-2016, the Zika virus (ZIKV) caused a major epidemic in the Americas, increasing cases of microcephaly and Guillain-Barré syndrome. During this period, the discovery of ZIKV sexual transmission intensified studies on the impact of this virus on the reproductive organs. For this study, 2-month-old male BALB/c mice were infected with 1.26 x 106 PFU/mL of ZIKV in solution via the intravenous route. After three, seven, and fourteen days post-infection (DPI), blood and testicle samples were obtained to detect ZIKV RNA. The authors observed that the infected animals had slower weight gain than the control group. Viremia occurred only at 3DPI, and the ZIKV RNA was detected in one testis sample at 7DPI. The histopathological analysis of this organ revealed intense disorganization of the seminiferous tubules' structure, inflammatory infiltrate, necrosis, hemorrhage, fluid accumulation, congestion of blood vessels, and reduced sperm count. Ultrastructural analysis showed nuclear changes in tubule cells, activation of interstitial cells, and morphological changes in spermatozoa, in addition to fragmentation and decreased electron density of the genetic material of these cells. Thus, despite causing predominantly asymptomatic infections, ZIKV can cause significant subclinical and transient damage, including to male reproductive organs. 20152016, 20152016 2015 2016, 2016 2015-2016 (ZIKV Americas GuillainBarré Guillain Barré syndrome period organs study 2monthold monthold 2 month old BALBc BALB c 126 1 26 1.2 10 PFUmL PFU mL route three seven postinfection post infection DPI, DPI , (DPI) group 3DPI 7DPI tubules structure infiltrate necrosis hemorrhage accumulation vessels count cells spermatozoa Thus infections damage 2015201 201 2015-201 12 1.

RESUMO O cádmio (Cd) é um poluente ambiental que afeta vários tecidos e órgãos, inclusive o testículo. Muitos estudos demonstraram que a toxicidade do Cd causa comprometimento testicular por meio de estresse oxidativo e ação inflamatória. Portanto, este estudo teve como objetivo demonstrar a toxicidade testicular do Cd e a ação protetora da zeólita contra os efeitos deletérios do cádmio. Ratos machos adultos receberam Cd em uma dose de 30mg/kg/dia por 28 dias consecutivos com ou sem zeólita, que foi administrada em uma dose de 100mg/kg/dia por 28 dias. Foram avaliados o peso dos testículos, os espermatozoides (contagem, motilidade e anormalidades), a testosterona sérica e o hormônio luteinizante (LH), as enzimas testiculares fosfatase ácida (ACP) e fosfatase alcalina (ALP), as citocinas inflamatórias fator de necrose tumoral alfa (TNF-α), interleucina-1beta (IL-1β) e fator nuclear Kappa B (NF-κB) e estresse oxidativo. Aqui, descobrimos que o cádmio causou alterações nas características dos espermatozoides, distúrbios nos hormônios sexuais, declínio nas enzimas testiculares, conteúdo elevado de malondialdeído (MDA), diminuição da glutationa (GSH), aumento do fator nuclear Kappa B (NF-κB) e níveis de citocinas pró-inflamatórias do fator de necrose tumoral alfa (TNF-α) e interleucina-1beta (IL-1β) no homogenato do testículo. Em contraste, a zeólita alterou significativamente esses efeitos deletérios, e o mecanismo em potencial envolveu a regulação negativa do Fator Nuclear Kappa B (NF-κB), do Fator de Necrose Tumoral Alfa (TNF-α) e da interleucina-1beta (IL-1β), restaurando a glutationa (GSH) e reduzindo o malondialdeído (MDA). Além disso, a zeólita foi associada a uma maior taxa de gravidez. Nossos dados sugerem que o estresse oxidativo e a inflamação são responsáveis pela lesão testicular induzida por Cd e que a administração conjunta de zeólita exerce um efeito protetor por meio da via NF-κB /TNF-α/IL-1β.

ABSTRACT Cadmium (Cd) is an environmental pollutant affecting various tissues and organs, including the testis. Many studies demonstrated that Cd toxicity causes testicular impairment through oxidative stress and inflammatory action. Therefore, this study aimed to demonstrate Cd's testicular toxicity and the protective action of zeolite against cadmium's deleterious effects. Adult male rats were given Cd at a dose of 30mg/kg/day for 28 consecutive days with or without zeolite, which was given at a dose of 100mg/kg/day for 28 days. Testis weight, sperm (count, motility, and abnormalities), serum testosterone and luteinizing hormone (LH), testicular enzymes Acid phosphatase (ACP) and Alkaline phosphatase(ALP), inflammatory cytokines Tumor Necrosis Factor Alpha (TNF-α) , interleukin-1beta (IL-1β) , and Nuclear Factor Kappa B (NF-κB) and oxidative stress were evaluated. Herein, we found that cadmium caused alterations in sperm characteristics, sex hormone disturbance, decline in testicular enzymes, elevated malondialdehyde (MDA) contents, decreased glutathione (GSH), increased Nuclear Factor Kappa B (NF-κB) and pro-inflammatory cytokines Tumor Necrosis Factor Alpha (TNF-α) and interleukin-1beta (IL-1β) levels in testis homogenate. In contrast, zeolite significantly amended these deleterious effects, and the potential mechanism involved the downregulation of Nuclear Factor Kappa B (NF-κB), Tumor Necrosis Factor Alpha (TNF-α) and interleukin-1beta (IL-1β), restoring glutathione (GSH) and reducing malondialdehyde (MDA). Also, zeolite was associated with an increased rate of pregnancy. Our data suggested that oxidative stress and inflammation are responsible for Cd-induced testicular injury and co-administration of zeolite exerts a protective effect via NF-κB /TNF-α/IL-1β pathway.

Abstract Tadalafil, a potent phosphodiesterase inhibitor 5 (PDE-5), is commonly used for the management of erectile dysfunction. However, its therapeutic potential extends beyond this indication. This study aimed to investigate the impact of tadalafil on the recovery of testicular parenchyma in male Wistar rats exposed to testicular thermal stress. Fifty-four Wistar rats were subjected to testicular thermal stress and randomly assigned to receive either tadalafil treatment (TAD) or no treatment (control). TAD was administered intraperitoneally at a dose of either 0.9 mg/kg or 1.8 mg/kg. Biometric parameters, histopathological assessment of the testis, serum testosterone levels, oxidative stress, and interleukin levels were evaluated on days 7, 15, and 30 after thermal shock. The animals were euthanized at the end of each experimental period, and samples were collected. TAD treatment maintained testicular weight and reduced the testicular degenerative process up to day 7 post-injury. However, despite TAD therapy, serum testosterone levels were decreased in the treated groups at days 7 and 15 post-thermal stress. TAD also decreased TNF-α and NO levels at different doses but had no effect on IL-6. The treatment with TAD after heat shock demonstrated anti-inflammatory and antioxidant properties but did not prevent the aggravation of testicular lesions in subsequent periods, even with the systematic reduction in TNF-α and NO levels. Therefore, this selective PDE-5 inhibitor, at the dosages used, did not have a positive impact on testosterone levels during the post-thermal stress period, which could compromise the resumption of the spermatogenic process.

ABSTRACT. Oxidative stress is the result of an imbalance between the production of oxidant precursors and the capacity of antioxidant defense. Oxygen free radicals play an important role in causing diseases. In this study, the protective effect of ethanolic avocado on apoptosis caused by oxidative damage in the tissue of albino rats was investigated. 24 male albino rats of the Faculty of Veterinary Medicine in Mosul, Iraq, which were kept in standard conditions for at least 10 days before and through the experimental work, were examined. Four groups of rats include the control group (healthy group), the group of male rats with ethanolic avocado consumption; The third group of male rats that were treated with 0.5% of hydrogen peroxide H2O2; and the fourth group of male rats that were treated with both 0.5% H2O2 and avocado ethanolic extract (50 mg kg-1 BW) for four weeks. After fixing the tissues of the liver, kidney, lung, spleen and testis in 10% buffered formalin, they were stained with hematoxylin. TUNEL assay was performed using the TUNEL cell death assay kit to detect apoptotic cells. In this investigation, the histology results in four groups of rats showed that in the rats that were treated with avocado, there were minor tissue changes in their liver, kidney, and intestine, and the tissues of these organs were healthy. In TUNEL staining, it was also shown that there are no apoptotic cells in the liver, kidney and testis cells in avocado-treated rats. The results showed that ethanolic Avocado is useful against oxidative stress damage and it may be used to protect tissues against oxidative stress.

Resumo O polvo com chifres Eledone cirrhosa, uma espécie de tamanho médio encontrada no Golfo Arábico ao largo da Arábia Saudita, foi coletado mensalmente no Golfo Arábico ao largo da cidade de Dammam durante o período de janeiro a dezembro de 2022. As amostras foram dissecadas e preparadas para exame por microscopia eletrônica. Durante a maturação genital, os túbulos seminíferos se estabelecem nos testículos, com espermatogônias ativas se dividindo. Espermatócitos 1 são observados no túbulo, seguidos de aumento de espermatogônias e espermatócitos em agosto. A espermiogênese começa com espermátides esféricas evoluindo para espermátides alongadas. Em setembro, as espermatogônias ativas, as divisões meióticas e o aumento da espermiogênese continuam. Os espermatozoides aparecem na Bolsa de Needham, indicando maturidade sexual. O ovário passa por vários estágios de desenvolvimento, com oócitos no estágio I em junho e julho, seguido pelo estágio II em outubro e novembro. No estágio IIIc, os cordões foliculares invadem o citoplasma do oócito, formando numerosas inclusões lipídicas e grânulos proteicos. O citoplasma contém cisternas de retículo endoplasmático e um Aparelho de Golgi pouco desenvolvido. O estágio IV ocorre em novembro, caracterizado pelo máximo desenvolvimento dos cordões foliculares e pelo início da vitelogênese. O ooplasma contém numerosas inclusões lipídicas, um sincício e células secretoras. A partir de dezembro, os oócitos do estágio V estão principalmente presentes, indicando a fase de atividade de secreção máxima. As plaquetas da gema acumulam-se no ooplasma do ovócito e o córion se forma na zona pelúcida. Em janeiro, os primeiros óvulos lisos são encontrados no ovário de alguns polvos e sua proporção aumenta continuamente. Este estudo teve como objetivo investigar a ação mitogênica da gonadotrofina bem como identificar os períodos de intensa multiplicação celular durante o ciclo sexual por meio de métodos citológicos. cirrhosa Saudita 2022 eletrônica genital testículos dividindo túbulo agosto alongadas setembro continuam Needham julho novembro IIIc oócito proteicos desenvolvido vitelogênese secretoras presentes máxima acumulamse acumulam pelúcida continuamente citológicos 202 20 2

Abstract The horned octopod Eledone cirrhosa, a medium-sized species found in Arabian Gulf off Saudi Arabia, was collected monthly from the Arabian Gulf off Dammam city during January to December 2022. Samples were dissected and prepared for examination using transmission electron microscopy. During genital maturation, seminiferous tubules are established in the testis, with active spermatogonia dividing. Spermatocytes 1 are observed in the tubule, followed by an increase in spermatogonia and spermatocytes in August. Spermiogenesis begins, with spherical spermatids evolving into elongated spermatids. In September, active spermatogonia, meiotic divisions, and increased spermiogenesis continue. Spermatozoa appear in Needham's pouch, indicating sexual maturity. The ovary undergoes various stages of development, with oocytes at stage I in June and July, followed by stage II in October and November. In stage III, follicular cords invade the oocyte's cytoplasm, forming numerous lipid inclusions and protein granules. The cytoplasm contains cisternae of endoplasmic reticulum and a poorly developed Golgi apparatus. Stage IV occurs in November, characterized by the maximum development of follicular cords and the beginning of vitellogenesis. The ooplasm contains numerous lipid inclusions, a syncytium, and secretory cells. From December, stage V oocytes are mainly present, indicating the activity phase of maximum secretion. Yolk platelets accumulate in the oocyte ooplasm, and chorion forms at the zona pellucida. In January, the first smooth eggs are found in some octopuses' ovary, with their proportion increasing steadily. This study aimed to investigate the mitogenic action of gonadotropin and identify the periods of intense cell multiplication during the sexual cycle using cytological methods. cirrhosa mediumsized medium sized Arabia 2022 microscopy maturation testis dividing tubule August begins September divisions continue Needhams Needham s pouch maturity July November III granules apparatus vitellogenesis syncytium cells present secretion pellucida octopuses steadily methods 202 20 2

Resumo Como o extrato aquoso da flor de Dolichandrone serrulata (DSF) demonstrou ter algumas propriedades farmacológicas, sua toxicidade sistêmica ainda não foi avaliada. Este estudo teve como objetivo investigar o efeito da toxicidade subcrônica do extrato de DSF em parâmetros bioquímicos e estruturas histológicas do fígado, rim, testículo e epidídimo mais os vasos deferentes. Ratos machos adultos foram administrados com DSF em 100, 300 e 600 mg / kg de peso corporal por meio de gavagem oral por 48 dias consecutivos, enquanto os ratos controle receberam água destilada. No final do experimento, amostras de sangue, fígado, rim, testículo e epidídimo mais canais deferentes foram coletados para determinar as alterações dos componentes bioquímicos séricos, incluindo ALT, ALP e níveis de creatinina e estruturas histológicas. Os resultados revelaram que o peso corporal e o consumo de comida ou água do controle e de todos os grupos tratados com DSF não foram significativamente diferentes. Verificou-se que o DSF aumentou significativamente o peso do epidídimo mais os canais deferentes, mas o rim e o fígado diminuíram no grupo de alta dose (P valor < 0,05). As alterações histológicas, incluindo fibrose de tais tecidos vitais e reprodutivos, não foram encontradas após a administração, mas os níveis de ALT, ALP e creatinina foram significativamente alterados nos grupos tratados (valor P < 0,05). No entanto, seus níveis alterados ainda estavam em intervalos normais. Em conclusão, esses achados demonstraram que o extrato da flor de D. serrulata não apresentou toxicidade subcrônica nas estruturas vitais e reprodutivas, mas alterou ligeiramente algumas funções hepáticas e renais.

Abstract Although Dolichandrone serrulata flower (DSF) aqueous extract has been shown to possess pharmacological properties, its systemic toxicity has still to be evaluated. The present study aimed to investigate the sub-chronic toxicity effect of DSF extract on biochemical parameters and histological structures of liver, kidney, testis, and epididymis plus vas deferens. Adult male rats were administered DSF at 100, 300, and 600 mg/kgBW via oral gavage for 48 consecutive days while control rats received distilled water. At the end of the experiment, blood, liver, kidney, testis, and epididymis plus vas deferens samples were collected to determine any changes to serum biochemical components including ALT, ALP, and creatinine levels and histological structures. The results revealed no significant difference in body weight and food or water consumption between control and the DSF-treated groups. It was found that DSF significantly increases the weight of epididymis plus vas deferens, while the kidney and liver showed a decrease in the high dose group (P value < 0.05). Histological changes in these vital and reproductive tissues including fibrosis were not observed after administration but ALT, ALP, and creatinine levels were significantly altered in the treated groups (P value < 0.05). These altered levels, however, were still within normal ranges. In conclusion, these findings demonstrated that D. serrulata flower extract had no sub-chronic toxicity on vital and reproductive structures but slightly altered some liver and kidney functions.

ABSTRACT Purpose: The gubernaculum seems to be the most important anatomical structure in the testicular migration process. The objective of this paper is to review current literature regarding the role of gubernaculum testis nerves in testicular migration. We conducted a comprehensive literature review about the gubernaculum testis innervation. A PubMed database search was performed in April 2024, focusing on gubernaculum testis and cryptorchidism and genitofemoral nerve (GFN) and calcitonin gene-related peptide (CGRP) gene. The gubernaculum has its own nerve supply, the GFN, descending on the anteromedial surface of the psoas muscle from L1-L2 segments. The second phase of testicular descent is regulated by androgens and CGRP, released from the sensory nucleus of the GFN. The GFN doesn't directly play a role in testicular migration but there is a theory that shows a regulatory function of this nerve in hormonal action during this process. The gubernaculum testis has important structural alterations during the testicular migration and the genitofemoral nerve and CGRP gene are of great importance in this process. The genitofemoral nerve provides motor innervation to the cremaster muscle and gubernaculum, which helps regulate the position of the testes within the scrotum.
