Resumo
In the feline species, progestins, GnRH agonist implants and melatonin implants are the three main non-surgical contraceptive approaches that are important to discuss today. When available, those can actually come handy in many clinical situations when surgery cannot be performed or should be avoided. To date though, those only offer short to medium term options. Research using gene therapy is however on its way, with encouraging preliminary results. A long term alternative using this technology might become available in the future, changing how we approach contraception in cats in our veterinary clinics.

Endometritis refers to an inflammation of the uterine mucosa that does not extend beyond the stratum spongiosum. Recent studies indicate it is a common finding in 30-50% of bitches suffering from infertility/subfertility. This disorder is subclinical, and its diagnosis involves sampling the uterus, whether it is by performing a cytology from flushing the organ or histology on collected uterine biopsies. Its pathophysiology remains unclear in 2021. Some cases are associated with cystic endometrial hyperplasia, which leads to disruption in the uterine clearance mechanisms after breeding ; while other appear as a pure inflammatory process. While we dont have all the answers yet, there is no doubt today that these disorders must be included in the differential diagnosis of infertility in the bitch. The work that has already been done on this topic already offers some idea on how to approach these cases in our veterinary clinics.
