The ovary (from Latin ōvārium 'egg, nut') is a gonad in the female reproductive system that produces ova; [1] when released, an ovum travels through the fallopian tube/oviduct into the uterus. There is an ovary on the left and the right side of the body.
The human female reproductive system is made up of the internal and external sex organs that function in the reproduction of new offspring. The reproductive system is immature at birth and develops at puberty to be able to release matured ova from the ovaries , facilitate their fertilization , and create a protective environment for the ...
Menstrual cycle The menstrual cycle is a series of natural changes in hormone production and the structures of the uterus and ovaries of the female reproductive system that makes pregnancy possible. The ovarian cycle controls the production and release of eggs and the cyclic release of estrogen and progesterone. The uterine cycle governs the preparation and maintenance of the lining of the ...

An ovarian follicle is a roughly spheroid cellular aggregation set found in the ovaries. It secretes hormones that influence stages of the menstrual cycle. At the time of puberty, women have approximately 200,000 to 300,000 follicles, [1][2] each with the potential to release an egg cell (ovum) at ovulation for fertilization. [3]
Ovulation marks the end of the follicular phase of the ovarian cycle, and the start of the luteal phase. Ovulation is the release of egg cells from the ovaries as part of the ovarian cycle for most vertebrates. In women, this event occurs at the end of the follicular phase, when the ovarian follicles rupture and release the secondary oocyte ...
In all mammals, the ovum is fertilized inside the female body. Human ova grow from primitive germ cells that are embedded in the substance of the ovaries. [10] The ovum is one of the largest cells in the human body, typically visible to the naked eye without the aid of a microscope or other magnification device. [11]
In animals (including humans), the male sex organs include the testicles, epididymides, and penis; the female sex organs include the clitoris, ovaries, oviducts, and vagina. The testicle in the male and the ovary in the female are called the primary sex organs. [1] All other sex-related organs are known as secondary sex organs.
