Dr. Héctor Izquierdo, gynecologist at IVF-Spain tells us in this video the adequate levels of estrogen and progesterone to carry out an embryo transfer. As the doctor tells us:
We don't have the case for an adequate level of estrogen to carry out the transfer or there are no studies described that tell us that a level must be reached. The important thing is that the endometrial line, the part of the uterus where the embryo is going to be implanted, is adequate, greater than 8 mm. In the case of progesterone, there is clinical data that shows us that a progesterone greater than 10 ng/dL helps the pregnancy to be effective.
