which aims to establish the presence or absence of bacteria, fungi and Trichomonas in the urogenital system of the patient. By Ordinance 28 of the Law for Assisted Reproduction the test is compulsory prior to any type of assisted reproductive procedure (intrauterine insemination or in vitro fertilization).

According to the recommendations of the World Health Organization before giving a sample for a microbiological smear, the patient should first urinate, then wash with soap the external genitalia and dry them. This should be done in order to minimize the risk of contamination with bacteria. Giving the sample in a specially designated room at the clinic is preferred to bringing it from home for the same reason.
