The hormones secreted by the ovaries include estrogen, progesterone and a small amount of androgen. Different hormones have different uses, as follows: 1. Estrogen, which plays a very important role in the growth and development of the body. It can help the vagina, fallopian tubes and uterus to mature gradually, and can also promote the stability of the body’s characteristics. 2. Progesterone, which is supported by estrogen, can only manifest itself. The main role of progesterone is in the three areas of breast, uterus and heat production. Progesterone can keep the body temperature stable when menstruating and keep the fetus stable when pregnant. 3, androgen, androgen is generally less in women’s bodies and is also less secreted by the ovaries. Its main role is to maintain body functions and organ development, but also to effectively regulate the pituitary gland, so one of the three hormones is indispensable.
