Fertility, fecundity, sex ratio and the accessory sex glands in male golden hamsters

The ventral prostates, dorsolateral prostates, coagulating glands (anterior prostates), ampullary glands and/or seminal vesicles of male golden hamsters were excised bilaterally. The effects of these treatments on fertility, fecundity and sex ratio of offspring were studied. Total removal of the glands or ablation of the ventral prostates alone reduced fertility. The lack of secretions from the coagulating glands and seminal vesicles in the seminal fluid all favoured a higher proportion of male pups born in a litter. Absence of all or any of these glands did not appear to affect litter size.
