About this study

This study aims to evaluate the impact of sexual intercourse and orgasm in the 72 hrs following embryo transfer of blastocysts on the clinical pregnancy rate. An impact on sexual activity and a decrease in the frequency of intercourse has been observed in infertile couples. In couples who undergo assisted reproductive technology (ART), sexual relations have an additional component that can condition them, such as the fear of influencing the outcome of the cycle. The usual practice in ART cycles has evolved towards a preference for blastocyst-stage embryo transfer, both in fresh in vitro fertilization (IVF) cycles and in frozen embryo transfer (FET) cycles. The investigators consider it important to elucidate whether coital intercourse after embryo transfer (ET) has an impact on the clinical pregnancy rate after the transfer of blastocyst-stage embryos.
