On the podcast today, I’m answering a question from Vicky who wrote in to Ask The Egg Whisperer. She wants to know “How much caffeine is ok for the 90 days pre IVF, during stim and after embryo transfer?” I get a lot of questions about how much caffeine is OK during IVF, and when patients are pregnant. It’s my opinion that in the three months before IVF, drinking coffee is not going to hurt your fertility. However, this is a situation where it’s best to go by the saying “everything in moderation.” When it comes to caffeine during stim, I actually sometimes recommend that my patients consider drinking coffee. Why? The meds can make you feel super sleepy when that estrogen fog rolls in. Those same medications can also make you constipated, and a little bit of caffeine can certainly help with the problems of constipation too. After embryo transfer, same thing: those meds just make you feel so sleepy, and sometimes you need a little bit of a pick-me-up.  However, once you're pregnant, coffee can make your heart race. It might make it harder for you to sleep, and cause insomnia, and that can be super irritating. So be careful if you're someone who feels a little anxious. You may want to consider limiting your intake. That said - “One to two cups per day don’t drive an embryo away.” To submit your own question to Dr. Aimee for a future episode of Ask The Egg Whisperer, click here.  Subscribe to my YouTube channel for more fertility tips!
