Diagram comparing reproductive pathways: arrows show sexual reproduction forming a diploid zygote from oocyte and sperm, haploid parthenogenesis forming a haploid individual, and two types of diploid parthenogenesis-automixis and apomixis-both resulting in diploid individuals. Symbols indicate haploid and diploid stages. — Animal reproductive system The process of sexual reproduction and several forms of parthenogenesis.

In many mammals, the process of ovulation is regulated by the pituitary gland through the secretion of gonadotropins, specifically follicle-stimulating hormone (FSH) and luteinizing hormone (LH).12

During the follicular phase of the reproductive cycle, FSH promotes the growth and maturation of ovarian follicles. As these follicles develop, they secrete increasing amounts of [estrogen]. This rising estrogen output acts via feedback on the pituitary gland to reduce FSH secretion while simultaneously stimulating the release of LH.231

Ovulation is triggered by a sudden, sharp peak in the secretion of LH. This surge of LH acts on the mature follicle, causing it to rupture and release the egg. Following this event, LH also facilitates the transformation of the ruptured follicle into the corpus luteum, which then begins to secrete progesterone. It is important to note that while this mechanism applies to many mammals, some species, such as cats and rabbits, ovulate in response to the physical stimulus of copulation rather than a spontaneous hormonal peak.23145
