Endometrial Lining and Post-Transfer Bed Rest

I recently saw a patient in my practice, Pacific Fertility Center, who had recently undergone a retrieval and she inquired about a couple matters that I get asked about all the time. For starters, she inquired as to what is the optimal endometrial lining on the day of the HCG shot (i.e. 36 hours before egg collection); i.e. 9 mm, 10 mm, 11mm, 12 mm, or greater; additionally, she inquired about the value of bed rest following an embryo transfer.

For starters, as long as the endometrial thickness reaches 8-9 mm with a good pattern, the pregnancy rates should be fine. There isn’t any strong evidence that endometrial thickness beyond 9mm (i.e. 10, 11, 12 mm etc.) will produce higher pregnancy rates.

Furthermore, bed rest is not necessary after an embryo transfer. Gravity does not play any role in implantation success, i.e. embryos do not fall out. We recommend you try to live as relaxed and stress free a life style you can. Eat a normal balanced diet with your prenatal vitamins and avoid exercise until the pregnancy test.

If this scenario sounds familiar to you, or if you have any additional questions, drop me a line. I’d love to hear from you!
