  • Roughly fifteen days before fertilization can happen, the anterior pituitary gland secretes the follicle-stimulating hormone, FSH, which ripens a couple of follicles of the ovary that then release estrogen. (hospitalninojesus.com)
  • When the estrogen level is high enough, the anterior pituitary gland releases a surge of LH, which triggers ovulation and causes the follicle to rupture and release the egg. (hospitalninojesus.com)
