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).

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

Patient discussion about Ovaria.

Q. my little sister have her periode badly.it stay for a months somethimes what can cause that? Since she start having her periode is been a problem and anybody cannot give us a straight answer she's been a hospitolize and had to have blood transfussion she's always anemic and sh'es been putting on pills but her body did not react good to it we had to stop.Sometimes she fells so weak that she pass out.The doctor say she may need to hospitolized again she doenst want to and we dont know how to help her she just wants a normal teenager and get ready to go away to collegebut we are scare that may not happens,she loves school so much and she feltthat she will never be a normal woman like everybody and scare that she may never have children one day i tell her to not be worry about it but i feel helpless.Please tell me what's wrong with her since nobody seems to give us a straight answers.Is follicular cyst of ovaries can put her in so much pain.

A. My daughter is 23 years old and has had a continuous period for 2 months. She had DNC surgery about a year ago - which helped for a few months. This situation has put a damper on her sexual lifestyle with her husband. Any idea what would cause this condition? Rhartman@txgas.com.

Q. Dear Doctors,I had cyst in my left ovary and poped it off,after that I have a small pain every day. in HSG everything was OK.my Pop smir is ok and in histroscopy every thing was ok. would you please ask me why I have this pain?

A. as Ann already mentioned - this is a good place to get good advises, not diagnosis... my advise to you is to ask the gyno how long there should be pain after the surgery. i'm sure it take couple of days minimum but i would ask him about it. if there's something wrong he'll know what to do.
sorry i can't help more...
