The female version of testes is ovaries. The ovaries are a pair of reproductive organs located in the female pelvis, one on each side of the uterus. They are made up of several different types of cells and produce hormones such as estrogen and progesterone. The ovaries also produce and release eggs (ova) during a woman's menstrual cycle. During sexual intercourse, the ovaries can also release up to two million eggs, which can potentially be fertilized by sperm.
In addition to producing eggs, the ovaries also produce and secrete hormones such as estrogen and progesterone. Estrogen is responsible for the development of female secondary sexual characteristics such as breast development and regulation of the menstrual cycle. Progesterone helps to regulate the menstrual cycle and prepare the uterus for pregnancy.
Unlike testes, which produce sperm cells, ovaries do not produce sperm. Instead, the sperm cells are produced in the testes and are then transported to the female reproductive system through the vas deferens.
Overall, the ovaries are the female equivalent of the testes and are responsible for the production of eggs and hormones. They are essential for reproduction and the development of secondary sexual characteristics in women.
