In couples where there is a decrease in sperm motility, intracervical pathology in the sense of chronic inflammation (capacitation, i.e., activation of spermatozoa occurs in the cervix) and at least one fallopian tube is patent, ovarian stimulation is performed on the patient, and on the days when ovulation is expected, sperm obtained through masturbation is collected, processed in the laboratory using one of the methods (swim-up or density gradient), and then returned to the uterine cavity via a catheter up to the openings of the fallopian tubes. An ultrasound is performed to check if ovulation has occurred, and a blood bHCG test is done two weeks after insemination.
