Ovulation is a key part of the menstrual cycle and involves several stages:
1. Follicular Phase: Starts on the first day of menstruation and ends with ovulation. Follicle-stimulating hormone (FSH) stimulates the growth of ovarian follicles.
2. Ovulatory Phase: A surge in luteinizing hormone (LH) triggers the release of a mature egg from the ovary. This usually occurs around the middle of the menstrual cycle.
3. Luteal Phase: After the egg is released, the empty follicle transforms into the corpus luteum, which secretes progesterone to prepare the uterine lining for a potential pregnancy.
Each phase plays a crucial role in preparing the body for a possible pregnancy.

Ovulation is a finely-tuned process involving hormonal interplay: 1. Follicle Development: In the first half of the menstrual cycle, follicle-stimulating hormone (FSH) from the pituitary gland stimulates the growth of ovarian follicles. 2.

Ovulation is a finely-tuned process involving hormonal interplay:
1. Follicle Development: In the first half of the menstrual cycle, follicle-stimulating hormone (FSH) from the pituitary gland stimulates the growth of ovarian follicles.
2. Mature Follicle Selection: Around mid-cycle, usually one follicle becomes dominant, maturing and producing estrogen.
3. LH Surge: The rise in estrogen triggers a surge in luteinizing hormone (LH) from the pituitary gland.
4. Egg Release: The LH surge causes the mature follicle to release its egg from the ovary into the fallopian tube, typically around day 14 in a 28-day cycle.
5. Luteal Phase: After the egg is released, the follicle transforms into the corpus luteum, secreting progesterone to prepare the uterine lining for a potential pregnancy.
This sequence ensures that an egg is available for fertilization during the most fertile part of the menstrual cycle.
