there is no clear evidence that activitiy restrictions after an embryo transfer increase pregnancy rates. . most of the reproductive endocrinologists that i work with do advise light activity for a few up to 14 hours but not strict bed rest. personally i do advise patients to avoid sexual intercourse for up to a week because the prostaglandins in semen can cause strong uterine contractions. again i believe that this is empiric as i don't know of good evidence that demonstrates that intercourse lower the chances of conception. unfortunately we don't have evidence to support everything that we do. .
what are the post-op instructions after an embryo transfer?
