Spontaneous conception during in vitro fertilization prior to embryo transfer during the COVID-19 lockdown

Abstract

Intercourse during IVF treatment traditionally had been discouraged for the purpose of avoiding trauma to the hyperstimulated ovaries, optimizing semen parameters, and preventing multifetal conception and ovarian hyperstimulation syndrome. The probability of spontaneous conception during an IVF cycle is minimal; however, a few cases have been reported in the literature. Recently, there was a case of unexplained infertility with no conception for 12 years and she conceived spontaneously post ovum pickup prior to embryo transfer. Previously she underwent six cycles of follicular monitoring timed intercourse and six cycles of IUI. Given the infrequent prevalence of such an occurrence, we aim to present and discuss this case.
