Ovaries are the sex organs of women and are the place where follicles develop and mature. Ovarian cells can secrete estrogen and progesterone, which play an important role in promoting the formation of female sexual characteristics and maintaining a certain level of sexual desire. If a woman has both ovaries removed, she can soon enter menopause and show signs of aging, so the ovaries are the most important gland for women. In the ovaries, the eggs can be discharged into the fallopian tubes after maturation. At this time, if they meet with sperm, they can develop into a fertilized egg, which can enter the uterus to be laid on the endometrium and can give birth to a new generation. If for some reason you are exposed to radiation for a long time or receive radiotherapy for a disease, you will easily damage your ovaries and may experience premature ovarian failure.
