The bovine dominant ovarian follicle.
Central roles in reproductive biology (i.e., growth and development of the oocyte, steroidogenesis, and ovulation) are played by the ovarian dominant follicle (DF). The DF is different from other follicles because it can escape atresia (the fate of all other follicles), and if exposed to the LH surge, its cells will differentiate into the corpus luteum. The DF was originally studied by looking ...
متن کاملOvulation of the preovulatory follicle originating from the first-wave dominant follicle leads to formation of an active corpus luteum
The objective of our study was to compare the characteristics of the corpus luteum (CL) formed after ovulation of the dominant follicle (DF) of the first follicular wave (W1) and those of the CL formed after ovulation of the DF of the second (induced) follicular wave (W2). Non-lactating Holstein cows were used for this study. In Experiment 1, cows were treated with PGF2α and GnRH on days 6 and ...

efl students gender and socioeconomic status: the use of politeness strategies in the first and second languages
within the components of communicative competence, a special emphasis is put on the “rules of politeness,” specifically the politeness strategies (brown and levinson, 1978) that speakers deploy when performing the request speech act. this is because the degree of imposition that making a request places upon one’s interlocutor(s) has been seen to be influenced by several factors among which, as ...
Endocrine dynamics associated with follicle development in pigs: a review
A significant increase in growth of follicles that are selected for ovulation seems to occur on days 14-17 of the estrous cycle. In pigs there is a continuous growth of follicles without appearance of dominant follicles or follicle waves during the estrous cycle. There is a general consensus that a decrease of FSH during the follicular phase is accompanied with the selection of ovulatory follic...
