Comparing two methods for frozen embryo transfer

This trial compares a new method to time a frozen embryo transfer (using a test called ERA) with the standard method. The goal is to find the best time to transfer a high-quality embryo in women who have had multiple failed IVF attempts (recurrent implantation failure).

This study compares two types of natural cycle preparation for frozen embryo transfers to see which leads to more pregnancies. It may be a good fit if you are using your own eggs, have regular cycles, and are planning a frozen embryo transfer.

This trial tests whether giving a medication called a GnRH agonist (which affects hormones) before a frozen embryo transfer can improve the chances of pregnancy in women with infertility. It aims to see if this treatment helps the uterus accept the embryo better.

This study compares two types of fertility medications (a natural progesterone injection versus a GnRH antagonist injection) to see which better prevents early ovulation during IVF when all embryos are frozen for later transfer. If you are freezing all embryos for medical or personal reasons, this trial may help improve your chances of success.

This trial compares two ways to prepare the uterus for a frozen embryo transfer: a natural cycle or a new method using hormonal stimulation during the early part of the cycle. It may help improve success rates for people using their own eggs and sperm.

This study measures changes in your blood immune markers during frozen embryo transfer when the embryo is chromosomally normal. It may help clinics understand what blood immune patterns relate to successful pregnancy in natural or hormone-prepared cycles.
