ovary /ova·ry/ (o´vah-re) the female gonad: either of the paired female sexual glands in which oocytes are formed.ova´rian Ovary. Inset shows the ovarian microstructure, with the stages of ovarian follicle development depicted counterclockwise from the top right, showing follicles progressively more mature: from primordial to primary, secondary, then tertiary, followed by ovulation, and finally corpora lutea from maturation to degeneration. polycystic ovaries ovaries containing multiple small follicular cysts filled with yellow or bloodstained thin serous fluid, as in polycystic ovary syndrome.
Ovary One of the two almond-shaped glands in the female reproductive system responsible for producing eggs and the hormones estrogen and progesterone. Mentioned in: Dysmenorrhea, Hormone Replacement Therapy, Infertility, Infertility Drugs, Menopause, Oral Contraceptives, Ovarian Torsion, Turner Syndrome ovary [ō′vərē] Etymology: L, ovum, egg one of the paired female gonads found on each side of the lower abdomen, beside the uterus in a fold of the broad ligament. At ovulation, an egg is expelled from a follicle on the surface of the ovary under the stimulation of the gonadotrophic hormones follicle-stimulating hormone (FSH) and luteinizing hormone (LH). The remainder of the follicle (corpus luteum) secretes the hormones estrogen and progesterone, which regulate the menstrual cycle by a negative-feedback system in which an increase in estrogen decreases the secretion of FSH by the pituitary gland and an increase in progesterone decreases the secretion of LH. Each ovary is normally firm and smooth and resembles an almond in size and shape. The ovaries generally are homologous to the testes. ovary pl. ovaries; the female gonad; either of the sex glands in the female in which the ova are formed and from which the sex hormones, estrogen and progesterone, are released. Small, round bodies varying in size with the species and the stage of the estral cycle, they are located one each at the end of the ovarian (fallopian) tubes, in the ovarian bursa. In birds two ovaries are present but usually the right one remains small and nonfunctional. accessory ovary very rare in domestic animals; usually located close to or attached to a normal ovary. See also supernumerary ovary (below). cystic ovary see cystic ovarian disease supernumerary ovary occurs widely situated from normal ovary, formed presumably from a separate anlage in contradistinction to an accessory ovary which results from a splitting of the embryonic gonad and is usually attached to the normal gonad. occult primary malignancy Occult cancer, unknown primary A malignancy of unknown 1º site or origin that is symptomless, which first manifests itself as metastases or secondary–paraneoplastic phenomena, and usually has a poor
prognosis; OPMs are problematic as appropriate therapy requires that the primary malignancy be eradicated, and many remain obscure despite aggressive diagnostic work-up; certain malignancies metastasize to certain sites with greater than expected
frequency; in OPMs affecting the brain, the primary arises in the lungs in up to 85% Treatment Up to 30% of Pts with metastases from an occult primary adenoCA may respond to chemotherapy–mitomycin C, adriamycin, vincristine; poor response is
more common in ♂ and in Pts with liver and/or infradiaphragmatic metastases
