There are certain conditions in which even after adulthood the eggs do not mature in the ovaries. Immature eggs in ovaries is the main cause of infertility in women. The ovaries are two small organs, about the size of your thumb, that are located in the female pelvis. They are attached to the uterus, one on each side, near the opening of the fallopian tube. The ovaries contain the female gamete cell, called the oocyte. In the female reproductive system, an egg matures in either one of the two ovaries this occurs approximately every 28 days.

The term is used when the female gamete is not capable of movement (non-motile). If the male gamete is capable of movement, the type of sexual reproduction is also classified as oogamous. Cryopreservationof ovarian tissue, often called ovarian tissue cryopreservation, is of interest to women who want to preserve their reproductive function beyond the natural limit, or whose reproductive potential is threatened by cancer therapy, for example in hematologic malignancies or breast cancer. The procedure is to take a part of the ovary and carry out slow freezing before storing it in liquid nitrogen whilst therapy is undertaken.
