AIM Viable spermatozoa could be recovered from the cauda epididymides for the purpose of preservation of genetic material of male animals with desirable traits and for use in reproductive biotechnology. The aim of this study was to determine the effect of storage time on testicular and epididymal biometry, sperm reserves and epididymal sperm characteristics of red Sokoto bucks post mortem. MA...

Studies on the beneficial effects of vitamins E and D supplementation on functions of caput and cauda epididymides, their spermatozoa, vas deferens and seminal vesicle of sodium fluoride (NaF) treated (10 mg/kg body weight) male mice (Mus musculus) were carried out. The NaF treatment resulted in significant decrease in the body and epididymis weight but those of vas deferens and seminal vesicle...

A number of reproductive parameters were evaluated in 12 adult indigenous boars. The seminal vesicles, prostate and bulbourethral glands had masses of 184.41 +/- 18.00 g, 16.69 +/- 2.42 g and 142.05 +/- 16.12 g, respectively, while the penile length measured 45.71 +/- 4.49 cm. The testes and epididymides had masses of 211.82 +/- 26.74 g and 108.81 +/- 11.49 g. The number of sperm averaged 2.78 ...

Cyclohexanol administration (25 mg/kg/day orally for 40 days) produced a brief period of infertility in rabbits by inhibiting the process of spermatogenesis at the spermatocyte and spermatid levels. Seminiferous tubule and Leydig cell nuclear dimensions were reduced. The lumen of epididymides and ductus deferens were devoid of spermatozoa. Cyclohexanol administration reduced the concentrations ...

Reports that men with mucoviscidosis were sterile and that portions of their genital tracts were atretic prompted us to investigate the genital tracts of 15 male infants with mucoviscidosis who died within the first year of life and came to necropsy. The genital tracts of all of these infants were abnormal, the abnormalities being confined to mesonephric derivatives. Hypoplastic or absent ducti...

Gonadal and extragonadal sperm reserves were determined in twenty sexually matured domesticated African greater cane rats. Mean (+/-SD) sperm numbers in testes and epididymides were 150.40+/-12.93x10(9) and 259.33+/-13.68x10(9), respectively. The mean epididymal distribution of spermatozoa was found as follows: 67.53+/-12.43x10(9) in caput, 89.10+/-13.20x10(9) in corpus, and 102.70 +/-13.71x10(...

Rats and mice were vasectomized to study the pathological changes in the development and resolution of vasectomy induced sperm granuloma. Epididymal weights were increased in all groups of vasectomized animals, whereas testicular weights did not change. Granuloma in the form of yellow nodular masses of cysts were present at the lower pole of the epididymis. It consisted of a pool of sperm and o...
