Abstract
The ventral prostates, dorsolateral prostates, coagulating glands, seminal vesicles and/or ampullary glands were bilaterally removed from adult male hamsters. Removal of these glands did not affect the fertilization rate and cleavage of the embryos at 48 h post coitum (p.c.). Air-dried preparations of the embryos showed a delay in cleavage at 72 h p.c. and a significant number of degenerated embryos was also found in females mated with males from which all the male accessory sex glands had been removed. A significant implantation loss was also observed at 122 h p.c. The results suggest that, in the golden hamster, removal of the male accessory sex gland causes a slower cleavage rate in embryonic development and a significant embryonic loss during pregnancy.
