Several hormones play a crucial role in the female reproductive system: - Estrogen: Produced primarily in the ovaries, estrogen is essential for the development of secondary sexual characteristics and the regulation of the menstrual cycle. - Progesterone: Another ovarian hormone, progesterone is crucial for preparing the uterus for pregnancy and maintaining it. - Follicle-Stimulating Hormone (FSH): Produced by the pituitary gland, FSH stimulates the growth of ovarian follicles. - Luteinizing Hormone (LH): Also produced by the pituitary gland, LH triggers ovulation and stimulates the production of estrogen and progesterone. - Testosterone: Although typically considered a male hormone, low levels of testosterone are also present in women and contribute to libido and bone health.
