Figure 1From: Endocrine and Ovarian Changes in Response to the Ram Effect in Medroxyprogesterone Acetate-primed Corriedale Ewes During the Breeding and Nonbreeding SeasonA) Diameter of the ovulatory follicle (RE:-■-; C:-◆-), and LH levels (RE:-●-; C:-▲-) normalized to ovulation. B) FSH (RE:-■-; C:-◆-) and estradiol-17β (RE:-●-; C:-▲-) normalized to the LH surge. Ewes were primed for 12 days during the breeding season with an intravaginal sponge containing 60 mg of MAP. Unlike control (C) ewes (n = 5), ram effect (RE) ewes (n = 6) were isolated from contact with rams 30 days before sponge withdrawal.Back to article page
