There are multiple causes of infertility and in many patients more than one cause may be present. AART begins with a thorough evaluation. Common causes of infertility can include abnormal sperm parameters in 35% of cases, ovulation and egg quality disorders in 25% of cases, pelvic adhesions, endometriosis, fallopian tube disorders, uterine disorders and, in 5%-10% of cases, specific factors cannot be identified.

Most of the tests required for infertility evaluation are done at certain times of the menstrual cycle. Treatment is seldom helpful until investigations are completed. Above all, success in establishing pregnancy requires a period of close cooperation between the patient, their partner and their medical team.
