Estradiol-17β (A) and FSH (B) concentrations in 14 ewes that were isolated from contact with rams for 30 days, and primed for 6 days with an intravaginal sponge containing 60 mg of MAP during the nonbreeding season; rams were introduced at sponge withdrawal. Time with respect to the sponge withdrawal is equal to the time for ram's introduction. Ewes ovulated and came into estrus (n = 5; -■-), ovulated without estrus (n = 5; -▲-), or neither ovulated nor came into estrus (n = 4; -◆-). BR = pooled values from the period before rams were introduced.
