Females have a pair of ovaries located in the abdomen.
ovary is the parimary female sex organ which produces one ovum during each menstrual cycle. ( Mature `underset(+)(O) 14 to 40` Year).
Ovary also produces two grups of steroid hormones called estrogen and progesterone.
ovary is composed of ovarian follicles and stromal tissues. The estrogen is synthesized and secreted mainly by the growing ovarian follicles.
After ovulation, the ruptured follicle is converted to a structure celled corpus luteum, which secretes mainly progesterone.
Estrogens produce wide ranging actions such a stimulation of growth and activities of female secondary sex organs, development of growing ovarian follicles, appearance of female secondary sex characters, mammary gland development etc.
Estrogens also regulate female sexual behaviour.
Progesterone supports pregnancy. It also acts on the mammary glands and stimulates the formation of alveoli which store milk and milk secretion.
