Preovulatory follicles were removed from ewes during estrus to determine hormonal, ovarian and behavioral responses. In Experiment 1, new follicles were recruited and ovulated within 4 days, and a second estrous period was observed in most ewes. In Experiment 2, follicles were removed at Day 0 (estrus), Day 3.5 and Day 7.0 to determine responses to repeated follicular removal in the absence of a corpus luteum (CL). Ewes in two groups were given exogenous progestin at the time of first or second surgery. Each follicular removal was followed by a surge of follicle-stimulating hormone (FSH) and follicular growth, and in many cases, behavioral estrus and/or a surge of luteinizing hormone (LH) was detected around the time of the next follicular removal. Although not necessary for display of estrus, treatment with progestin during follicular maturation increased the number of ewes showing estrus. When the newly developing follicles were allowed to ovulate, resulting corpora lutea produced low levels of progesterone or had a short life span.
