Summary. The article presents
the research results as to the negative impact of the usage of progestin hormonal
contraceptive drugs on the reproductive system in clinically healthy cats and
dogs and in the emergence of this pathology at different methods of
application. During the research 243 cats and 134 dogs were examined, four
research groups of healthy cats and dogs aged from 1.5 to 5 years were selected
and formed for studies. All groups of animals were prescribed
oral hormone containing contraceptive drugs with active ingredient megestrol acetate. Groups were formed
according to the common animal owners asked oral hormonal contraceptive for the
suppression of sexual function in cats and dogs. Medicaments were
prescribed to the experimental animals within 2 years. It was proved that the best way to use progestogenic
drugs for cats and dogs is a period of about 7–15 days before the estrus.
The changes that have occurred are reversible in the reproductive system. In
the appointment of contraceptives at the time of proestrus
increases the probability of disease of the reproductive system in cats and
dogs. When using the direct drugs for interrupting the heat in cats and dogs,
especially in a dose at 2–6 times exceeded, it
could lead to irreversible damage of the reproductive system in most animals.
