Abstract Background In vivo studies involving molecular markers of the follicle wall associated with follicular fluid (FF) milieu are crucial for a better understanding of follicle dynamics. The inability to obtain in vivo samples of antral follicle

The negative effect of estradiol-17beta (E2) on LH, based on exogenous E2 treatments, and the reciprocal effect of LH on endogenous E2, based on hCG treatments, were studied throughout the ovulatory follicular wave during a total of 103 equine estrou

Regulation of circulating gonadotropins by the negative effects of ovarian hormones in mares

Autor: O J, Ginther, E L, Gastal, M O, Gastal, M A, Beg

Publikováno v: Biology of reproduction. 73(2)

The functional and temporal relationships between circulating gonadotropins and ovarian hormones in mares during Days 7-27 (ovulation = Day 0) was studied using control, follicle ablation, and ovariectomy groups (n = 6 mares/group). In the follicle-a

Differential blood flow changes between the future dominant and subordinate follicles precede diameter changes during follicle selection in mares

Autor: T J, Acosta, E L, Gastal, M O, Gastal, M A, Beg, O J, Ginther

Publikováno v: Biology of reproduction. 71(2)

Diameter deviation during a follicular wave is characterized by the continued growth of the developing dominant follicle and reduced growth and regression of the subordinate follicles. This study considered the hypothesis that reduced blood flow in t
