Unexplained infertility is diagnosed when a couple is unable to conceive despite standard fertility evaluations showing no identifiable cause of infertility. These evaluations generally include assessment of ovulation, fallopian tube function, and semen parameters.

Depending on the woman’s age, duration of infertility, previous treatments, and individual medical circumstances, treatment options may include ovulation stimulation combined with intrauterine insemination (IUI). If pregnancy does not occur after an appropriate number of treatment cycles, IVF may be considered following specialist evaluation. Treatment recommendations vary according to individual fertility factors.
