It is a female reproductive organ that produces female gamete or eggs.

It is present in flowering plants as well as animals

In flowering plants it is the ovary that turns in to the fruit.

The fertilized female gamete turns in to the seed.

Ovaries are egg-producing reproductive organs found in female organisms. They are part of the vertebrate female reproductive system. Ovaries in females are homologous to testes in males. The term gonads refers to the ovaries in females and testes in males.

As female mammals develop within the womb, each ovary develops a number of immature eggs associated with groups of other cells called follicles. While mammals were thought to develop their entire supply of eggs prenatally and soon after birth, new evidence from laboratory mice has called this into question, showing that female mice in fact produce new eggs throughout their reproductive lifetime. However, there is no direct evidence showing that human females produce new eggs after birth. As the animal becomes reproductively mature (the process called puberty in humans), eggs will periodically mature and be released from the ovary (a process called ovulation) so that they will be available for fertilization by sperm. A fertilized egg resulting from union with a sperm becomes a zygote and then an embryo as it develops.

In humans, an egg launched from an ovary has to traverse a slight space before entering the fallopian tube and moving gradually down to the uterus. If fertilized, it implants itself into the lining of the uterus and develops as the pregnancy continues. If the fertilized egg settles into the fallopian tube instead of the uterus an ectopic pregnancy will result. Ectopic pregnancy can also happen if a fertilized egg settles onto the cervix or onto the ovary itself, or if a fertilized egg passes through the gap between the ovary and the fallopian tube into the abdomen
These hormones serve many functions:

They induce and maintain the physical changes of puberty and the secondary sex characteristics.
They support maturation of the uterine endometrium in preparation of implantation of a fertilized egg.
They provide signals to the hypothalamus and pituitary that help maintain the menstrual cycle.
Estrogen plays an important role in maintaining subcutaneous fat, bone strength, and some aspects of brain function

Ovaries are oval shaped and, in the human, measure approximately 3 cm x 1.5 cm x 1.5 cm. The ovary (for a given side) is located in the lateral wall of the pelvis in a region called the ovarian fossa. The fossa usually lies beneath the external iliac artery and behind the ureter.

part of the reproductive system of all female vertebrates. Although not vital to individual survival, the ovary is vital to perpetuation of the species. The function of the ovary is to produce the female germ cells or ova, and in some species to elaborate hormones that assist in regulating the reproductive cycle.

The ovaries develop as bilateral structures in all vertebrates, but adult asymmetry is found in certain species of all vertebrates from the elasmobranchs to the mammals.

The ovary of all vertebrates functions in essentially the same manner. However, ovarian histology of the various groups differs considerably. Even such a fundamental element as the ovum exhibits differences in various groups.

ovary:. One of a pair of female reproductive glands in which the ova, or eggs, ... The ovaries are located in the pelvis, one on each side of the uterus



Normal Ovary and Polycystic Ovary The ovaries are two small organs, ... In women with PCOS, the ovary doesn't make all of the hormones it needs for any of

Polycystic ovary syndrome (PCOS) can result in irregular menstruation, excess hair growth and obesity.

In girls with PCOS, the ovaries produce higher than normal amounts of certain hormones, which can interfere with egg development and release
