Synonym(s): premature ovarian failure.

ovarian

pertaining to an ovary.

ovarian agenesis
one or both ovaries absent; usually accompanies defects of the tubular reproductive organs.
ovarian anomaly
includes ovarian dysgenesis (see below), agenesis (above) or hypoplasia, as in Swedish Highland cattle.
ovarian bursa
a pouch formed by the mesosalpinx and the mesovarium that encloses the infundibulum of the uterine tube and the ovary. It is shallow in the mare and does not enclose the ovary. It is capacious in sows and deep with a fat-filled wall in the bitch.
ovarian bursitis
inlammation of the ovarian bursa; likely to affect the function of the ovary and ovulation.
ovarian cycle
the cycle of follicle maturation and rupture, then luteinization and regression of the corpus luteum followed by recommencement of the cycle, unless pregnancy intervenes.
ovarian cyclicity
the regular appearance of estrus as an indication of the regular occurrence of estrous cycles.
ovarian cyst
see cystic ovarian disease (below).
cystic ovarian degeneration
persistent cysts derived from ovarian follicles which do not ovulate. Follicular cysts are thin-walled and fluctuant, and often multiple. Luteal cysts have a thick wall of luteal tissue about the cyst, are firm to palpate and do not rupture easily. There is abnormal estral behavior, either anestrus or nymphomania, and diminished fertility.
Cystic corpora lutea form after ovulation has occurred and do not interfere with reproduction. They have a characteristic ovulation papilla.
cystic ovarian disease
common disease of cows, less common in sows, characterized by gross abnormalities of estrus, either anestrus or more frequent and prolonged. In cows the cysts can be palpated per rectum.
ovarian dysgenesis
small, inactive ovaries lacking germ cells such as occur in mares lacking a second X chromosome.
ovarian follicle
see ovarian follicle.
follicular ovarian cyst
see cystic follicle.
ovarian hormones
estrogens, progesterone.
ovarian hypoplasia
functional hypoplasia in immature females and undernourished females of all ages are common findings; in the absence of these risk factors hypoplasia is genetic in origin in Swedish Highland and possibly white Ayrshire cattle.
ovarian imbalance
an alternative name of endocrine dermatoses caused by abnormalities of ovarian function in bitches. Type I, associated with cystic ovaries or functional ovarian tumors, consists of a bilaterally symmetrical alopecia, gynecomastia, enlargement of the vulva, and abnormalities of the estrous cycle. Type II is a bilaterally symmetrical alopecia, sometimes with seborrhea, in spayed bitches. It is responsive to treatment with estrogen. Called also estrogen-responsive dermatosis.
ovarian inflammation
intrafollicular ovarian hemorrhage
hemorrhage into an ovarian follicle occurs in all species during ovulation; also rarely in anovulatory follicles.
luteal ovarian cyst
see luteal cyst.
luteinized ovarian cyst
see luteal cyst.
ovarian neoplasms
includes mostly granulosa cell tumors, but also rarely carcinomas, fibromas, thecomas, sarcomas.
ovarian pain
a rare cause of colic in mares; identifiable by eliciting pain by rectal palpation of ovary.
premature ovarian failure
defective differentiation of ovarian tissue and the patient shows no signs of pubertal estrus until long past the customary age.
ovarian rebound
return of cyclical ovarian activity after a period of inactivity, usually pregnancy and parturition.
ovarian remnant syndrome
the return of estral activity in a desexed female; due to failure to remove all of the ovarian tissue or to dropping, and allowing to implant, a piece of the ovary.
rete ovarii ovarian cyst
a convoluted system of epithelial cell cords and tubules occupying part of the ovarian medulla; the cysts are found mostly in the hilar region of the ovary.
ovarian serous inclusion cyst
similar in size and appearance to, but distinguishable from, ovarian cysts by their intraovarian position; lined by cuboidal epithelium thought to be pinched off from indentations of surface epithelium.
tubular epithelial ovarian cyst
formed from epithelial cells from the surface of the ovary.
