Collection of Eggs from the Fallopian Tube of the Rat

Abstract

DURING the course of recent experiments in collaboration with Mr. P. C. Williams, an account of which will be published later, it has been noted that ovulation and superovulation can be produced in both intact and hypophysectomized immature rats by a single injection of mare serum gonadotrophin followed by a single injection of chorionic (urinary) gonadotrophin. In hypophysectomized rats, ovulation takes place 13–14 hours after the administration of the luteinizing hormone (chorionic gonadotrophin). The number of eggs produced may be very large; in one rat no less than forty-nine eggs were present in the Fallopian tubes.
