By the end of the follicular (or proliferative) phase of the thirteenth day of the menstrual cycle, the cumulus oophorus layer of the preovulatory follicle will develop an opening, or stigma, and excrete the oocyte with a complement of cumulus cells in a process called ovulation.
14 sie 2023 · There are two distinct phases of ovarian follicle development: gonadotropin-independent growth and gonadotropin-dependent growth. These phases also are known as pre-antral growth and antral growth, respectively. The gonadotropins are follicle-stimulating hormone (FSH) and luteinizing hormone (LH).
The follicular phase, also known as the preovulatory phase or proliferative phase, [1] is the phase of the estrous cycle (or, in primates [2] for example, the menstrual cycle) during which follicles in the ovary mature from primary follicle to a fully mature graafian follicle.
1 gru 2023 · Although assessed in only two cases to date, the administration of LH for a 1- or 2-month period has been shown to contribute to an increase in AFC, suggesting that LH has a positive effect on the progression of follicles through the early stages of folliculogenesis (La Marca and Longo, 2022).
18 sty 2022 · The pre-ovulatory period is the phase of the menstrual cycle in which follicular development occurs that will lead to an ovarian follicle becoming the so-called dominant follicle. This dominant follicle contains the oocyte that will be released into the fallopian tubes with ovulation.
11 maj 2017 · Pre-antral follicular development includes the primary to secondary follicle transition and the development of secondary follicles to the per-antral stage. When follicles leave the resting pool, the granulosa cells become cuboidal and begin to express markers of cell proliferation.
22 sty 2007 · Mural granulosa cells: targets and transducers of ovulatory signals. Pre-ovulatory follicles contain two distinct sublineages of granulosa cells that arise during folliculogenesis as the cell populations segregate upon formation of the fluid-filled follicular antrum.
