The ovary (from Latin ōvārium 'egg') 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 ovaries are endocrine glands, secreting various hormones that play a role in the menstrual cycle and fertility.
An ovary releases an egg around the middle of your menstrual cycle (around day 14 of a 28-day cycle) in a process called ovulation. Each of your ovaries has thousands of ovarian follicles. Ovarian follicles are small sacs in the ovaries that hold immature eggs.
The ovary is the female gonad. It is a paired intraperitoneal endocrine organ typically found in the lower left and right quadrants of the abdomen, respectively.

Making, storing, and releasing ovary hormones. Your ovaries produce two types of hormone: estrogen and progesterone. Estrogen is an important hormone for both sexes, though less is produced by males.
Learn about the structure, location, components and function of the female gonads, the ovaries. Find out about the ligaments, vasculature, lymphatic drainage and innervation of the ovaries, and their clinical relevance.
Learn about the structure, location, blood supply, and function of the ovary, the female gonad that produces eggs and hormones. Find out how the ovary develops from the embryonic gonadal ridge and releases ova in a cyclic manner.
In the ovary, all eggs are initially enclosed in a single layer of cells known as a follicle, which supports the egg. During the follicular phase (first part of the menstrual cycle), one or two ovarian follicles grow due to the action of FSH. As the follicle grows it produces oestradiol. As oestradiol levels rise this induces the hypothalamus ...
By puberty, when you'll most likely receive your first period, the number of eggs in each ovary is around 200,000-400,000. During the childbearing years, approximately 300-500 eggs will develop and be released during ovulation. After menopause, the ovaries will stop producing eggs and atrophy (shrink). Due to a loss of ovarian functioning ...
The ovary is a ductless reproductive gland in which the female reproductive cells are produced. Females have a pair of ovaries, held by a membrane beside the uterus on each side of the lower abdomen.
