What’s the truth about the results?

Based on their analysis, the researchers concluded that IVF might result in more pregnancies than other treatment options for unexplained fertility, but this remains uncertain and more research is needed on birth rates, adverse outcomes, and costs.

As outcomes, future trials should use adverse effects and cost of treatments as well as birth rates.

For now, said Dr. Pandian, "IVF is becoming popular when there is no specific explanation for infertility and it may be able to overcome a variety of problems. However, it is expensive, complicated, and can have many adverse effects, such as multiple births."
