In the primitive jawless fish, and some teleosts, there is only one ovary, formed by the fusion of the paired organs in the embryo.

Except in teleosts, the oviduct does not directly contact the ovary.

The most primitive ray-finned fishes retain the simple structure also found in lungfishes, but in teleosts, folds of peritoneum enclose the ovary and upper part of the tube, fusing them into a single structure.

Mosquitofish are within the infraclass teleostei and as all teleosts, mosquitofish lack a uterus so production of oocytes and gestation occur within the ovary of a female mosquitofish.

The ovary is inferior with often a thin tubular portion at its apex formed by joined tepals or the tip of the ovary.

In the narrowest definition, the Amaryllidaceae sensu stricto is characterized by an umbellate inflorescence with an inferior ovary.

The ovary is superior.

* Ovary: The end of the mammal oviduct nearest to the ovary is the infundibulum of uterine tube

The ER is expressed in specific tissues including the ovary, uterus and breast.

The ovary is an ovum-producing reproductive organ, often found in pairs as part of the vertebrate female reproductive system.

The ovary ( for a given side ) is located in the lateral wall of the pelvis in a region called the ovarian fossa.

The part of the broad ligament of the uterus that covers the ovary is known as the mesovarium.

Thus, the ovary is the only organ in the human body which is totally invaginated into the peritonium, making it the only intraperitoneal organ ( not to be confused with interperitoneal ).

In birds, reptiles, and monotremes, the egg is relatively large, filling the follicle, and distorting the shape of the ovary at maturity.

Amphibians and reptiles have no ovarian medulla ; the central part of the ovary is a hollow, lymph-filled space.

In most birds and in platypuses, the right ovary never matures, so that only the left is functional.

The procedure is to take a part of the ovary and carry out slow freezing before storing it in liquid nitrogen whilst therapy is undertaken.

The ovary is superior with basal or free-central placentation.

The ovary is superior.

The ovary is inferior and topped by two nectaries, the stigma is funnel-shaped.

An individual that produces both types of gametes is called hermaphrodite ( a name applicable also to people with one testis and one ovary ).

The ovary is three-celled, ripening into a three-celled capsule.

A recent finding indicates that ovary development and maintenance is an active process, regulated by the expression of a " pro-female " gene, FOXL2.

However, once ovulation occurs, in addition to estrogen, the ovary will also start to produce progesterone.

Plants which reproduce sexually also have gametes, however, they are produced in the anther and ovary.

A scar also may remain on the seed coat, called the hilum, where the seed was attached to the ovary wall by the funiculus.

For example, 46, XY individuals who have a female phenotype, but also have testes instead of ovaries --- a group that includes all individuals with complete androgen insensitivity ( CAIS ), as well as some individuals with partial androgen insensitivity ( PAIS ) --- are classified as having " male pseudohermaphroditism ," while individuals with both an ovary and a testis ( or at least one ovotestis ) are classified as having " true hermaphroditism .".

Abdominal adhesions from other intraabdominal surgery, or ruptured ovarian cysts can also affect tubal motility needed to sweep the ovary and gather an ovulated follicle ( egg ).

Semi-conservative therapy preserves a healthy appearing ovary, but also increases the risk of recurrence.

Central obesity is a symptom of Cushing's syndrome and is also common in patients with polycystic ovary syndrome ( PCOS ).

The pistillate ( female ) flowers are also without calyx or corolla, and consist of a single ovary accompanied by a small, flat nectar gland and inserted on the base of a scale which is likewise borne on the rachis of a catkin.

The female flower also has no calyx or corolla, and comprises a single-celled ovary seated in a cup-shaped disk.

However, it is also effective in treatment of hirsutism associated with insulin resistance ( e. g. polycystic ovary syndrome )

There is also evidence that leptin plays a role in hyperemesis gravidarum ( severe morning sickness of pregnancy ), in polycystic ovary syndrome and a 2007 research suggests that hypothalamic leptin is implicated in bone growth.

All these symptoms are non-specific and can also arise with a range of problems other than cancer, and a diagnosis can only be made following confirmatory investigations such as computed tomography ( CT ) scans, laparotomy and / or a biopsy of the ovary.

The fruit of the family Asteraceae is also so similar to an achene that it is often considered to be one, although it derives from a compound inferior ovary ( with one locule ).

Neighboring accessory cells in the ovary can also provide nutritive help of two types.

The ovary is often also associated with a storage sac for sperm, and a copulatory duct termed Laurer's canal.

Royalactin also induces similar phenotypical change in the fruitfly ( Drosophila melanogaster ), marked by increased body size and ovary development.

Estrone ( E1, and also oestrone ) is an estrogenic hormone secreted by the ovary as well as adipose tissue.

GnRH and GnRH receptors are also found in cancers of the breast, ovary, prostate, and endometrium.

Polycystic ovary syndrome ( also known as Stein-Leventhal syndrome ) and hyperprolactinemia can also cause anovulatory cycles through hormonal imbalances.

Patients who are suffering from Stein-Leventhal syndrome ( also referred to as polycystic ovary syndrome, or PCOS ) can also suffer from anovulation.
