Gonadal and extragonadal sperm reserves of the domesticated adult African greater cane rat (Thryonomys swinderianus).
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(...
متن کاملOn the development of extragonadal and gonadal human germ cells.
Human germ cells originate in an extragonadal location and have to migrate to colonize the gonadal primordia at around seven weeks of gestation (W7, or five weeks post conception). Many germ cells are lost along the way and should enter apoptosis, but some escape and can give rise to extragonadal germ cell tumors. Due to the common somatic origin of gonads and adrenal cortex, we investigated wh...

15 صفحه اولTesticular development, daily sperm production and epididymal sperm reserves in 15-mo-old Angus and Hereford bulls: effects of bull strain plus dietary energy.
Bull calves (n = 143) were obtained from two strains of Angus and two strains of Hereford cattle for which replacements were selected on the basis of superior feedlot growth performance on either high- or medium-energy diets. From weaning to slaughter at 15 mo of age, bulls were fed either the high-energy (80% grain + 20% forage) or medium-energy diet (100% forage) corresponding to their strain...
