Should We Offer In Vitro Fertilization to Couples with Unexplained Recurrent Pregnancy Loss?

In clinical practice, empirical treatments are often offered to couples with recurrent pregnancy loss, including in vitro fertilization.

At present, there is not enough evidence to justify IVF as a treatment option in couples with unexplained recurrent pregnancy loss.
