What Are The Best Days For Embryo Implantation
What is the range of E2 and P4 levels to assure "best probability" of implantation? Day before embryo transfer E2 was 182.2 and P4 was 35.9.
Normal: For progesterone the "range" is not so important as being above a certain level (no one is sure what that is tho!) Most docs would say 35.9 is plenty. You don't say whether frozen-or-fresh transfer, so the numbers can differ, but for a frozen (?) transfer anything between about 150-400 would be considered good. Ask your own doc for more specific answers about the plan, and good luck! ...Read moreSee 1 more doctor answer

Uterus and embryos: Failed implantation is common. An aneuploid embryo, with abnormal chromosomes is likely the cause. A receptive uterus requires normal structure of the uterine lining and surrounding uterus. Hormone preparation and timing must be correct. The transfer procedure itself is sometimes problematic. Cycle monitoring, medications, and ultrasound are essential. Check with an expert in rei. ...Read moreSee 1 more doctor answer

Verifying an appropriate uterine environment (Sonohysterogram or Hysteroscopy). Best of luck ...Read more
Can tetrogens cross to an embryo at implantation? Or does this only happen once the placenta is formed?
Yes, they can: Placenta and embryo evolve from the same structure, which is the clump of cells that originate from the division of the fused sperm/egg. Without blood supply from the mother, these events could not happen. So, with the blood to the evolving fetus/placenta, come the teratogens to the embryo. ...Read more
