Abstract

The article provides an overview of professional literature on reproductive studies of cats, the definition of the main factors influencing the development of infertility in cats: hormonal changes, lack of sufficient stimulus during pairing, leading to ovulation, inability to fuse, ovarian cyst, chronic inflammatory processes in reproductive organs systems, infections, some parasites or the simplest, hereditary problems, including chromosomal abnormalities (genetic or congenital defects such as pseudoharmophioditis, true hermaphroditism, mosaicism, infantilism, freemantry) described congenital aplasia of the ovaries, trauma affecting the reproductive organs. The conditions of detention that considerably affect the reproductive system are considered. It has been established that insufficient stimulation is one of the most common causes of infertility, which is relevant for cats because they are characterized by induced ovulation. Most animals with an abnormal set of sex chromosomes are infertile, treatment methods have not been developed. Inadequate feeding is perhaps the most important cause of infertility in cats. The connection between lack and (or) excess in the diet of Calcium, Phosphorus, Iodine, Cobalt, Cuprum, Manganese, other macro-and micro elements, and inability to reproduce is established. The role of microorganisms in the emergence of infertility of cats of infectious diseases (leukemia, infectious peritonitis, panleukopenia, chlamydia, toxoplasmosis) is considered. Extension of the intraperitoneal period arises from the stage of the anestrus. Such clinical picture is observed in cats older than 8 years with hypothyroidism and hyperadrenocorticism, obesity and cachexia, the appointment of drugs with antinuclear activity. Among gynecological diseases in cats, the most common diseases are pyometra, endometritis and vaginitis. It has been established that the most frequently diagnosed diseases of the uterus of female dogs and cats are cystular hyperplasia of the endometrium in combination with the pythometer, data on the etiopathogenesis of these diseases is given. The scientific data on the application of ultrasound diagnostics, hormonal level studies, vaginal cytology, the use of hysterosalpingography, x-ray for more accurate diagnostics of causes of infertility of cats are given.
