Rabbit Zygote Transport and Development Following Various Methods of Ovulation Induction

Abstract

Ovulation was induced in artificially inseminated rabbits by injection of LH [luteinizing hormone], HCG [human chorionic gonadotrophin] or cupric sulfate. Naturally mated does served as controls. Fewer ova were released following copper-induced ovulation, but neither tubal transport of the zygotes nor their rate of development appeared to be altered by the substances injected. The degree of ovum development attained by 48 or 72 hr of gestation was not related to rate of travel through the reproductive tract. Endometrial activities of carbonic anhydrase and alkaline phosphatase were also determined.
