| ovarian branch of uterine artery | Terminal branch of uterine artery (with tubal branch) which runs through mesovarium supplying ovary from medial aspect and anastomosing with ovarian branch of ovarian artery. Synonym: ramus ovaricus arteriae uterinae. (05 Mar 2000) |
|---|---|
| ovarian bursa | <anatomy> The peritoneal recess between the medial aspect of the ovary and the mesosalpinx. Synonym: bursa ovarica. (05 Mar 2000) |
| ovarian cancer | <gynaecology, oncology> A malignant tumour of the ovary is the leading cause of death from gynaecologic malignancies. Often diagnosed in later stages, symptoms include abdominal pain, increasing abdominal girth and abnormal uterine bleeding. Birth control pill use is thought to reduce the risk of ovarian cancer. (05 Jan 1998) |
| ovarian colic | Lower abdominal pain due to torsion or twisting of an ovary, as with an ovarian cyst. (05 Mar 2000) |
| ovarian cycle | The normal sex cycle which includes development of an ovarian (graafian) follicle, rupture of the follicle with discharge of the ovum, and formation and regression of a corpus luteum. (05 Mar 2000) |
| ovarian cyst | <gynaecology> The ovary will form a fluid filled cyst on the surface of the ovary each month after an egg is released from the ovary during normal ovulation. Larger cysts can cause pain and bleeding (rupture). (27 Sep 1997) |
| ovarian cystic disease | <gynaecology> A painful condition associated with the recurrent formation of large ovarian cysts. Distention of the ovarian capsule causes pain and rupture of a larger cyst can, in rare instances, cause internal bleeding. Treatment often includes hormone manipulation (birth control pills). (05 Jan 1998) |
| ovarian cysts | General term for cysts and cystic diseases of the ovary. (12 Dec 1998) |
| ovarian dysmenorrhoea | A form of secondary dysmenorrhoea due to disease of an ovary. (05 Mar 2000) |
| ovarian failure, premature | Premature failure of ovulation associated with hypergonadotropinism and hypoestrogenism in women under the age of 40. The aetiology appears to be multifactorial and many cases are idiopathic. When follicles are present but the ovaries are unable to respond to gonadotropins, resistant ovary syndrome results and this may be associated with autoimmune disease. Even when there is a loss of ovarian follicles, it is not always complete. Permanent and irreversible loss of follicles is termed premature menopause (menopause, premature). (12 Dec 1998) |
| ovarian fibroma | <radiology> Bilateral in 10%, malignant counterpart (fibrosarcoma) very rare, associated with Meigs syndrome (12 Dec 1998) |
| ovarian fimbria | The longest of the fimbriae of the uterine tube; it extends from the infundibulum to the ovary. Synonym: fimbria ovarica, infundibulo-ovarian ligament. (05 Mar 2000) |
| ovarian follicle | <biology, gynaecology> In mammals the group of cells around the primary oocyte proliferate and form a surrounding noncellular layer. A space opens up in the follicle cells and the whole structure is then the ovarian Graafian) follicle. (05 Jan 1998) |
| ovarian fossa | A depression in the parietal peritoneum of the pelvis; it is bounded in front by the obliterated umbilical artery, and behind by the ureter and the uterine vessels; it lodges the ovary. Synonym: fossa ovarica, Claudius' fossa. (05 Mar 2000) |
| ovarian function tests | Methods used for assessment of ovarian function. (12 Dec 1998) |
