How does eastragen effect the realse of egg?

Estrogen doesn't directly *cause* the release of an egg (ovulation). It plays a crucial role in the process, but it's not the trigger. Here's how it works:

1. Follicular Development:

* During the first half of the menstrual cycle, estrogen levels rise gradually.

* This rising estrogen stimulates the growth and development of follicles in the ovaries.

* Inside these follicles, eggs mature.

2. LH Surge:

* The rising estrogen levels eventually reach a peak, which triggers a surge in luteinizing hormone (LH) from the pituitary gland.

* This LH surge is the crucial signal for ovulation.

3. Ovulation:

* The LH surge causes the dominant follicle to rupture, releasing the mature egg (ovum) into the fallopian tube.

Therefore, estrogen is essential for follicle development and maturation, but it's the LH surge that triggers the actual release of the egg.

In summary:

* Estrogen: Prepares the follicle and egg for release.

* LH Surge: The final trigger for ovulation.
