![عکس صفحه اول مقاله: Follicle and systemic hormone interrelationships during spontaneous and ablation-induced ovulatory waves in mares Follicle and systemic hormone interrelationships during spontaneous and ablation-induced ovulatory waves in mares](/preview/png/2074293.png)
The characteristics of ovulatory follicular waves were studied for spontaneous waves and waves induced during the next estrous cycle by ovarian follicle ablations and administration of PGF2α 10 days after ovulation in 21 mares. In the induced group, both the days of the FSH surge and day of deviation were more synchronized, LH concentrations were greater before and after deviation, estradiol concentrations were greater after deviation, and the ovulatory follicle grew at a faster rate (3.4 ± 0.2 compared with 2.7 ± 0.1 mm/day). The frequency of two dominant follicles/wave was not different between induced waves (7 of 21) and spontaneous waves (9 of 21), but both dominant follicles ovulated more frequently in induced waves (6 of 7 waves compared with 0 of 9).
