Effect of Primidone Drug on LH, FSH, Testosterone Hormones Concentration and Testicular Tissue Changes in Adult Male Rat
Background: Primidone is effective in the treatment of epilepsy. In this research the effects of primidone on LH, FSH, testosterone hormones, body weight and testicular tissue in adult male rats, was studied. Material and Methods: In this experimental study, 50 adult male Wistar rats, weighing approximately 180-200 g were divided into 5 groups of 10 animals. Groups: control group, Sham group an...
متن کاملSeasonal variation in seminal characteristics, testicular measurements and plasma testosterone concentration in Iranian Khalkhali bucks
The aim of the present study was to determine seasonal variations in semen characteristics, testicular size, and plasma testosterone concentration in Iranian Khalkhali goats. An artificial vagina was used to collect semen from 10 bucks (2–4 years of age), from November 2013 to October 2014. Testicular circumference was higher (P<0.05) from September to October. Ejaculate volume, sperm ...
متن کاملEnvironmental and Genetic Contributors to Salivary Testosterone Levels in Infants
Transient activation of the hypothalamic-pituitary-gonadal axis in early infancy plays an important role in male genital development and sexual differentiation of the brain, but factors contributing to individual variation in testosterone levels during this period are poorly understood. We measured salivary testosterone levels in 222 infants (119 males, 103 females, 108 singletons, 114 twins) b...
متن کاملPopulation variation in age-related decline in male salivary testosterone.
BACKGROUND Age-related declines in free and bioavailable testosterone are frequently reported for Western populations, but interpopulation variation in this pattern has not previously been investigated. METHODS Salivary testosterone was measured using a consistently applied protocol on morning samples collected from men in four populations (USA, Congo, Nepal, and Paraguay) representing differ...
متن کاملEffect of tamoxifen on testosterone concentration and sperm count in adult male rats
Introduction: Tamoxifen is a nonstroidal antiestrogen prescribed for treatment of breast cancer. The aim of this study was to investigate the effect of tamoxifen on testosterone level in the serum and sperm count in the epididymis of adult male Wistar rats. Methods: Three groups of rats received 200, 400 and 600 µg/kg body weight tamoxifen dissolved in solvent (60% ethanol in physiological ...
