		Each ovary is about the size and shape of an almond.
		The ovaries are the main source of female hormones, which control the development of female body characteristics, such as the breasts, body shape, and body hair.

		In humans, the ovaries are two whitish rounded bodies about 25 mm/1 in by 35 mm/1.5 in, located in the lower abdomen on either side of the uterus.
		In botany, an ovary is the expanded basal portion of the carpel of flowering plants, containing one or more ovules.
		The ovaries of female animals secrete the hormones responsible for the secondary sexual characteristics of the female, such as smooth, hairless facial skin and enlarged breasts.

	Carpel - Wikipedia, the free encyclopedia
		In these flowers, the ovary lies physically lower than the lobes of the sepals and petals and below the point of attachment of the stamen filaments — the ovary is still considered to be superior but the flower is termed perigynous.
		In those flowers in which the floral tube is fused with the ovary, the sepals, petals, and stamens appear to grow out from the top of the ovary, and the flower is said to be epigynous and have an inferior ovary.
		The position of the ovary is an important consideration in the identification and classification of plant species, as well as the kind of fruit that develops after fertilization.

	MSN Encarta - Ovary
		Ovary, in anatomy, organ of female animals, including humans, that produces reproductive cells called eggs, or ova (see Reproductive System).
		Each ovary is composed of two portions: an external, or cortical, portion, and a deep, medullary portion.
		The ovary secretes hormones (see Hormone) that, together with secretions from the pituitary gland, contribute to secondary female sexual characteristics and also regulate menstruation.

		In vertebrate animals the ovary also secretes the sex hormones estrogen and progesterone, which control the development of the sexual organs and the secondary sexual characteristics.
		The interaction between the gonadotropic hormones from the pituitary gland and the sex hormones from the ovary controls the monthly cycle in humans of ovulation and menstruation.
		There are two ovaries in the human, held in place on each side of the uterus by a membrane; each ovary is about the size of an almond.

	Polycystic Ovary Syndrome- Health Encyclopedia and Reference
		Polycystic ovary disease (PCO) is a syndrome (cluster of problems) characterized by anovulation, amenorrhea, hirsutism, and infertility.
		Under normal circumstances, follicles deep within the ovaries are stimulated to grow, mature, and rise to h surface of the ovary, where they burst and release an egg to the Fallopian tube, a process controlled by pituitary hormones.
		Polycystic ovary may also be associated with a variety of problems in the hypothalamic-pituitary-ovarian axis, with extragonadal sources of androgens, or with androgen-producing tumors.

	Chickscope 1.5: Explore: Embryology: Day 5 - What Came First - the Chicken or the Egg?: Formation of the Egg...
		In the ovary the follicular cells surrounding the oocyte take the yolk and other nutrients from the bloodstream and pass them along to the oocyte.
		Consequently, the oocyte and the ovarian follicle it is nested in is continually pushed toward the outer edge of the ovary, until it is connected to the ovary by only a stalk.
		Shortly after release from the ovary, the egg's nucleus undergoes meiosis to prepare it for fertilization.

	NBasic Imaging > Ultrasound of Uterus and Ovary
		The normal ovary in the resting (menstrual) phase is moderately echogenic, well marginated and located in the lateral edge of the broad ligament.
		Ovaries are small, and often show a uniform moderately echogenic solid structure.
		Within a given ovary, only one of the developing follicles is "selected" to become a dominant mature graafian follicle, and to ovulate.

	Polycystic ovary syndrome
		Polycystic ovary syndrome is the most common hormonal disorder among women of reproductive age in the United States, affecting an estimated 5 percent to 10 percent.
		In polycystic ovary syndrome, your body produces an excess of androgens, and your ratio of LH to FSH is often abnormally high.
		In the absence of ovulation, the menstrual cycle is irregular or absent.

	Ovary 1
		Most of the mass of the ovary is divided into an outer cortex and an inner medulla.
		The stroma (which is found in both the cortex and medulla) is the region of connective tissue deep to the tunica albuginea into which follicles and blood vessels are embedded.
		In this large view of the ovary you can see several stages of follicular development, the earliest of which are the primordial follicles.

	ACS :: Treatment for Germ Cell Tumors of the Ovary
		Women with benign (non-cancerous) germ cell tumors such as mature teratomas (dermoid cysts) are cured by removal of the portion of the ovary (ovarian cystectomy) containing the tumor, or rarely, by removal of the entire ovary.
		If cancer has spread beyond the ovaries (stage IC and higher), the involved ovary and tube will be removed and debulking may be done (removing as much cancer as possible without damaging or removing essential organs).
		If careful staging has determined that a grade 1 immature teratoma is limited to one or both ovaries, the patient may be treated by removing the ovary or ovaries containing the cancer and the fallopian tube or tubes.

	Ovarian Cancer (Cancer of the Ovary) - Patient UK
		Ovaries are small and round, each about the size of a walnut.
		The ovaries and other internal organs can be seen and biopsies (small samples) can be taken to be looked at under the microscope to detect and confirm cancer cells.
		If the cancer is at a very early stage, (just confined to the ovary and not spread) then an operation to remove the affected ovary and associated fallopian tube may be all the treatment required.

	Polycystic Ovary Disease
		Twenty-four (39%) had characteristic polycystic ovaries on ultrasound, an exaggerated response of 17-hydroxyprogesterone to leuprolide, or both, suggesting ovarian hyperandrogenism and the diagnosis of mild polycystic ovary syndrome.
		The aim of this study was to quantify pulsatile LH secretion, burst frequency and mass, LH half-life, and the approximate entropy (ApEn) or (dis-) orderliness of LH release in adolescents with polycystic ovary syndrome (PCOS), combining a high-precision immunofluorimetric LH assay with deconvolution techniques.
		Polycystic ovary syndrome (PCOS) is classically characterised by ovarian dysfunction (oligomenorrhoea, anovulation and infertility), androgen excess (hirsutism and acne), obesity, and morphological abnormalities of the ovaries (cystic enlargement and stromal expansion).

	Follicular Cystic Ovary Disease: Overview - The Merck Veterinary Manual
		However, all the signs relate to the focal primary lesions, namely, thin-walled cysts in the ovary and the disruption of the normal endocrine events of the estrous cycle—especially absence of the negative feedback of progesterone from the CL on the hypothalamus and pituitary.
		The actions of the various hormones produced or the absence of the stabilizing action of high progesterone from the normal CL during ~75% of the estrous cycle (or both) are responsible for the changes seen in the genital tract, body conformation, and general behavior.
		Under the influence of hormones produced by the cystic ovary or the lack of hormones (especially progesterone) normally present during estrous cycles, the uterus undergoes palpable changes, which in turn vary with the duration of the cystic condition.

		Dr Carina Hilders and her colleagues believe that by moving the whole of the ovary and its blood vessels and attaching it to blood vessels in the arm, the success rate will be greatly improved.
		During the surgical treatment for the cervical cancer, they removed one of the patient's ovaries and transplanted it to the front of her left upper arm.
		However, they pointed out that it would not be suitable for women treated with chemotherapy because this cancer treatment targets the whole body and could potentially damage the ovaries regardless of where they are located in the body.

	Long-Term consequences of Polycystic Ovary (Site not responding. Last check: 2007-09-23)
		However, several attempts have been made to quantify the prevalence of polycystic ovaries in community-based studies (3-5) suggesting that approximately 20% of women of reproductive age demonstrate the ultrasound picture of polycystic ovaries, with half that number having clinical or biochemical signs of anovulation pr androgen excess.
		Jarvele and colleagues(13) found that the ovaries defined as polycystic (based on finding 8 or more subcapsular follicles of 2-8mm in diameters) were larger than normal ovaries, but they could not find any difference in echogenicity of the stroma between polycystic ovaries and normal ovaries.
