Treatment for infertility will depend on the underlying cause. Unfortunately, not all causes can be treated by surgery, medications, or both. Even if the suspected underlying cause of infertility has been treated, not all women will conceive. In about 10% to 15% of infertile couples, the cause is usually not found after a standard clinical and laboratory evaluation. This is term as unexplained infertility. Deciding what to do, if anything, when a fertility evaluation is completed may not be easy. Any treatment for conceiving is actually “maximizing fertility potential” rather than “curing infertility.” There is no guarantee that any of them will result in the successful birth of a baby. Ultimately, if conventional therapies do not achieve the desired pregnancy, then the last resort will be assisted reproductive technology (ART). This refers to procedures such as in vitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI).
