As the term implies, unexplained infertility is a type of infertility whose cause is unknown. The diagnosis is given to couples who have tried to conceive for 1 year (when the female’s age is under 35 years) or 6 months (when the female’s age is over 35 years) after all other causes have been ruled out, i.e. ovulatory function, uterine cavity, fallopian tubes, and semen analysis are normal.

When deciding on a treatment, we take into consideration the female’s age, her ovarian reserve (how many eggs she has), the duration of the couple’s infertility, and how many children the couple would like to have. Effective treatments include superovulation and intrauterine insemination (IUI), and when those don’t work our high success rate with in vitro fertilization (IVF) should reassure couples that their chances of “taking a baby home” are excellent.
