Frequently, couples will undergo all the recommended diagnostic tests for infertility and there will be no answer to the cause of the infertility. This does not mean nothing is wrong; it means that at this point in fertility research, the cause of the problem cannot be identified.

However, unexplained infertility is among the most successfully treated diagnoses. The treatment for unexplained fertility centers around the fact that these women are able to get pregnant, but may need assistance to have the event occur sooner. Treatment tries to speed up the occurrence of this event.
