Complete Bed Rest After Embryo Transfer: Myths & Facts

Traditionally, bed rest has been recommended for women after any medical procedure. For instance, after delivery of a baby, women were prescribed 6 weeks of bed rest until it was ultimately proven that that inactivity increased their risk of DVT (blood clots in the deep veins).

Now that IVF has been around for around 4 decades, it is time to review how we advise patients going through treatment and reconsider whether bed rest is still advisable.

In the early days of IVF, women were restricted to bed rest for 2 weeks after an embryo transfer. In fact, patients were not even allowed to stand up for quite some time after the procedure. Instead they were transported to a hospital gurney and relocated to a hospital bed—even using a bedpan when required instead of going to the toilet. It gradually became apparent that such severe limitation wasn’t needed. Back in 1997, the first study appeared suggesting that even a 24 hour period of bed rest was unnecessary. Specifically they demonstrated that even when patients were only limited to 20 minutes of activity restriction; pregnancy rates were comparable.

Subsequently, in 2005 a much larger and well-designed study found that when patients were allowed to get up immediately after their embryos were placed; their pregnancy rates were as good as patients that were asked to lie flat for an hour. Finally, a 2011 review of all the published research on this subject confirmed that there is no advantage to bed rest and instead that there may be a disadvantage being totally sedentary. This isn’t surprising since inactivity combined with high levels of oestrogen can promote blood clot formation as well as a rise in insulin resistance. In contrast, exercise reduces inflammation, lowers stress hormone levels and promotes healthy blood flow.
