a surge in the level of the luteinizing (LH) hormone.
primary follicle/oocyte
LH Leutenizing hormone- it stimulates the release of the oocyte into the fallopian tube, i.e. ovulation. [Do not confuse with FSH- follicle stimulating hormone, which stimulates the growth/maturation of the follicle containing the oocyte IN the Ovary.]

graafian follicle
Once the oocyte has been released from the follicle, it is swept up into the fallopian tube by the fimbriae. The oocyte then begins its journey towards the uterus, where it may be fertilized by sperm if present. If fertilization occurs, the resulting embryo implants in the uterus and pregnancy begins.
Yes, although the odds are lower. A dominant follicle is a single follicle with a maturing oocyte in it that is much larger than all the other follicles that started to develop in this cycle. The dominant follicle is the one that will eventually rupture and release a fertile oocyte, so not having a dominant follicle means the cycle is more likely to not be a fertile cycle.

The central chamber of the Graafian follicle is known as the antrum. It is a fluid-filled space that forms during the maturation of the follicle, containing follicular fluid rich in hormones and nutrients. The antrum plays a crucial role in the development of the oocyte and is involved in the regulation of follicular growth and ovulation. As the follicle matures, the antrum enlarges, leading to the eventual release of the oocyte during ovulation.
A primary follicle consists of a primary oocyte surrounded by a single layer of enlarged cuboidal epithelium. Recall that previously, there was a primary oocyte in a primordial follicle surrounded by a thinner single layer of squamous follicular cells.
The hormone that plays a crucial role in the development and release of a secondary oocyte is luteinizing hormone (LH). It is released by the pituitary gland and triggers ovulation, the process by which the mature ovarian follicle releases the secondary oocyte.
