Hypoplasia of Genitals

Ovarian hypoplasia. is the condition in which we present the ovaries small, bean-like, generally smooth surface, without forming follicles and corpora lutea. Clinically no show zeal and ovulation . The absence of heat deficit is a consequence of hormones .

It points to a congenital disorder that depends on hereditary factors linked to a recessive gene for “incomplete penetrance”.

Depending on the volume of the ovaries or the ovaries and the presence or absence offollicles on the surface, establishing the following classification:

First group: Hypoplasia complete. Extremely low and without ovarian follicles.

Second group: Shortage of primary follicles and some secondary and tertiary follicles are atretic.

Third group: Ovaries bearing follicles emit some fecundables eggs.

The internal and external genital tractus is often undeveloped due to a hypofunctioning hypoplastic rudimentary gonads, mainly when it is bilateral.

The hypoplasia may be bilateral or unilateral. In the latter case the ovary often affected is the left, as physiologically in the cow has a lower production capacity.

During the rectal examination the ovary hypoplastic may appear as a slight bulge in the broad ligament, without exceeding the size of a bean.The normal ovary may undergo compensatory hypertrophy.

In cases of double or bilateral hypoplasia, also appears underdeveloped genital tract in general and of the udder.

Unilateral hypoplasia is associated with low fertility and are longer periods between one pregnancy to another.

The pelvis is generally underdeveloped and females may have a certain type of intersex.

Do not give up two or three scans at least several months apart, in animals kept under different conditions to their optimal medium as a result of poor management, change of environment, exploitation and poor nutrition , especially in the time of development, the animal may have identical injuries ovary and not in the rest of the genitals.

Diagnosis is based on clinical data, symptoms and results of repeated rectal examination. To establish an accurate differential diagnosis should provide the optimal forms of exploitation and breeding.

The hypoplasia is recommended the reinstatement of the best means of exploitation and breeding. The use of estrogens is not recommended.

In cases of hypoplasia proven ovarian genetic trait, the only rational behavior to continue is to eliminate the female reproduction and implementation of proper methods of selection and breeding, to prevent the spread of disease by animals showing unilateral hypoplasia or bilateral third group.

It is important to detect hypoplastic bulls for fertility reduced, leading players in the spread, and remove them from production.
