Human chorionic gonadotropin (hCG) is a natural hormone that helps with the final maturation of the eggs and triggers the ovaries to release the mature eggs (ovulation). It also stimulates the corpus luteum to secrete progesterone to prepare the lining of the uterus for implantation of the fertilized egg.

Which hormone is responsible for ovulation?

Luteinizing hormone (LH), the other reproductive pituitary hormone, aids in egg maturation and provides the hormonal trigger to cause ovulation and the release of eggs from the ovary.

Does LH stimulate ovulation?

LH plays an important role in sexual development and functioning. In women, LH helps control the menstrual cycle. It also triggers the release of an egg from the ovary. This is known as ovulation.
