Anestria

In veterinary medicine, anestria is the term given to the absence of oestrus . The term can denote both the complete absence of the sexual cycle , better referred to here as acyclie , as well as the quiet running of the sexual cycle ("quiet heat", anaphrodisia ). The cause is impaired ovarian function .

Physiologically, anestria is before puberty and during pregnancy . Acyclie can be congenital in malformations of the ovaries. But it can, even in adverse environmental conditions, nutritional deficiencies ( "Hunger sterility"), after difficult births and at very high milk yield , pyometra , ovarian cysts and ovarian tumors occur. In bitches , hypothyroidism , hyperprolactinemia and overactive adrenal glands are also possible causes. Treatment depends on the cause.
