Swimming exercise for 1, 2 and 3 hr for 5 days/week for consecutive 4 weeks, results in a significant reduction in testicular, epididymal, prostetic, seminal vesicle somatic indices; epididymal sperm count, sperm motility; preleptotine spermatocytes, mid pachytene spermatocytes and stage 7 spermatids; plasma levels of testosterone, luteinizing hormone; testicular delta5, 3beta-hydroxysteroid de...
Background: The aim of this study is to survey the protective effects of betaine against cadmium and on sperm quality including progressive motility, sperm membrane integrity, concentration as well as testicular weight. Materials and Methods: Thirty adult male rats were allocated to the following three groups (n=10 in each group): control-saline, cadmium-saline and cadmium-betaine. Induction of...
Background: Given diabetes mellitus has an adverse effect on spermatogenesis and male fertility, the aim of the present study was to investigate the effect of L-carnitine administration on spermatogenesis and testicular structure in diabetic rats induced with Stereptozotocin. Methods: In this experimental study, fifteen rats were randomly divided into 3 groups: control group was received citra...
context to review and summarize the literature regarding the current status of postchemotherapy laparoscopic retroperitoneal lymph node dissection (pcl-rplnd) in patients with testicular germ cell tumor. evidence acquisition a comprehensive review of the english literature was performed using the pubmed database using the terms “laparoscopy” or “laparoscopic”, retroperitoneal lymph node dissect...
conclusions the inhibition of mini-puberty period in male rats was demonstrated to have an effect on their testicular function to some extent. results serum t and lh levels peaked at two hours after birth, while fsh peaked at hour 0, and bilateral testicular weight peaked at four hours after birth. the rats that underwent ether inhalation five minutes after birth had markedly reduced serum horm...
Background and purpose: Studies have indicated that phytoestrogens in soybean can influence the reproductive system. The aim of this study was to investigate the effect of hydroalcoholic extract of soybean on testicular tissue and pituitary-gonad axis in male rat. Materials and methods: Forty adult male Wistar rats were randomly allocated into five groups including control, sham, and three...
Adult male wild rabbits were exposed to artificial daylengths of 8L:16D, 13L:1 1D or 20L:4D after being taken from the wild during September, when testicular size was minimal. In all groups the testes grew and those in 20L:4D grew more quickly than did those in 8L:16D or 13L:11D. Rabbits kept in the 3 daylength treatments for the whole study maintained enlarged testes after the initial growth p...
This study investigated the effects of sub-chronic administration of sub-lethal doses of amitraz on some testicular parameters of Albino rats. Twenty-four adult male Albino rats (100 ± 10 g) randomly assigned into four groups were used for the study. Groups A, B and C received 10.0, 2.0 and 0.4 mg/kg amitraz in 10 ml/kg water while group D received equivalent volume of water orally and daily fo...
Many studies have demonstrated an association between diffuse bilateral testicular microlithiasis (TM) and gonadal and extragonadal germ cell tumors. Nevertheless, it is still uncertain whether ultrasound surveillance is really necessary in patients with TM in the absence of other risk factors such as previous testicular cancer, a history of cryptorchidism or testicular atrophy. We report the c...
