The third category for preventing pregnancy works by suppressing the action of an egg maturing in the ovary.

This hormone cocktail suppresses ovulation, keeping the immature egg safely sequestered in the ovary.

Roughly fifteen days before fertilization can happen, the anterior pituitary gland secretes follicle stimulating hormone, FSH, which ripens a handful of follicles of the ovary that then release estrogen.

Once the egg leaves the ovary, it is directed into the Fallopian tube by the finger-like fimbriae.

And with menstruation what happens is the brain triggers the ovary to start producing an egg.

But with menstruation, that choice comes from the ovary.
