Testicular weight, Sertoli cell number, daily sperm production, and sperm output of sexually mature rabbits after neonatal or prepubertal hemicastration.
The present study was conducted to investigate the influence of hemicastration and age at hemicastration on the subsequent testicular development of male rabbits through sexual maturity. Thirty New Zealand white rabbits were left intact or were hemicastrated on Day 35, 49, 77, or 105 postconception.

T ESTICULAR spermatid reserves have been quantified for bulls, buffalo-bulls, deer, boars, rabbits, guinea pigs, roosters and humans. Generally, a modification of the technique described by Amann and Almquist (1961) has been used. Daily sperm production can be calculated by dividing the value for testicular spermatid reserves by a time divisor which is the number of days of production these res...
متن کاملInfluence of naturally unilateral cryptorchidism on the histomorphometry of the testes and daily sperm production in West African Dwarf goats
Quantitative histology of the descended testis of unilateral cryptorchid bucks was compared with testis of normal bucks to evaluate the reproductive potentials of the scrotal testis in unilateral cryptorchids, using light microscopy techniques. The contralateral scrotal testes of the unilateral cryptorchids and the testes of the normal bucks contained profiles of seminiferous epithelium and eac...
متن کاملMethamphetamine induces abnormal sperm morphology, low sperm concentration and apoptosis in the testis of male rats.
Methamphetamine has been reported to be an important drug in the field of reproductive toxicology. The aim of this study was to investigate the effects of methamphetamine administrations on sperm morphology, sperm concentration and apoptotic activity inside seminiferous tubule in male rats. Rats were administered a dose of 8 mg kg(-1) , intraperitoneally (IP), for acute group and a dose of 4 mg...
