Abstract
IT has been postulated1–3 that a waning corpus luteum in the presence of a developing follicle is necessary to produce œstrus in the ewe. One attempt to test this hypothesis by treating the anœstrous ewe with 2–5 mgm. progesterone before gonadotrophin injection yielded negative results1. Pretreatment with 40–100 mgm. testosterone propionate has resulted in some 75 per cent incidence of œtrus following pregnant mare serum injection4; but rates of conception are low. This low conception is due to either suppression of ovulation or to faulty synchronization between ovulation and œstrus3.
