Frozen Embryo

Why to Consider a Frozen Embryo Transfer Rather Than a Fresh Embryo Transfer?

People who experience difficulties conceiving naturally can opt to pursue Assisted Reproductive Technology (ART) treatments like in-vitro fertilization (IVF). In a fresh (ET) or frozen embryo transfer (FET), reproductive endocrinology and fertility specialists transfer an embryo to a patient’s uterus to help patients conceive. FETs and ETs work differently and can have unique advantages depending on the patient’s body and needs.

At MCRM Fertility, we offer both frozen and fresh embryo transfers to improve the chances of conception. A fresh embryo transfer involves the retrieval of an egg, its fertilization and transfer of resultant embryo to the uterus after about five days of embryo development. Frozen embryo transfers usually occur several weeks but can occur even years after the original oocyte retrieval and fertilization. Here are some considerations as to why your fertility doctor may recommend or you may choose to have a frozen embryo transfer (FET):

Potentially Higher Pregnancy Rates

Women with PCOS or endometriosis may have higher live birth rates following a frozen embryo transfer rather than a fresh embryo transfer. This is because the hormonal effects from an egg retrieval on the uterine lining have dissipated by the time of the frozen embryo transfer.

Safer Recovery from IVF

Fresh embryo transfers entail higher risks of ovarian hyperstimulation syndrome (OHSS). OHSS is a condition in which a very high ovarian response to medications in IVF, given before an egg retrieval, may lead to some of the body’s water leaking from the blood vessels into the abdomen. OHSS can be very uncomfortable and unsafe. With frozen embryo transfers, the risks of OHSS can be minimized.

Opportunity for Embryo Genetic Testing

Our clinic offers pre-implantation genetic testing for aneuploidy (PGT-A) testing of embryos to ensure an embryo has a normal chromosomal number and/or knowledge of embryo sex prior to transfer. By freezing embryos, time is allowed for genetic experts to evaluate for healthy embryos and selection of preferred sex if so desired. Frozen embryo transfers of chromosomally normal embryos selected by PGT-A testing have higher probability of causing live births, especially in certain age groups. Patients with specific genetic disorders may benefit from more in-depth testing of the embryo’s genes through the use of pre-implantation genetic testing for monogenic disorders (PGT-M). PGT-M, also necessitates a frozen embryo transfer rather than a fresh embryo transfer. Selection of a nonaffected embryo reduces the risk of passing along a genetic disorder to a child.

Less Costly Fertility Treatment

ART and fertility treatments can be expensive. Prior to egg retrieval, patients will likely have to undergo fertility testing and purchase medications. Conception is not guaranteed after an embryo transfer; however, one advantage of IVF is often surplus embryos that may be frozen for future embryo transfers. Thus, if the first embryo transfer does not lead to a pregnancy, a patient can undergo a frozen embryo transfer of an existing embryo rather than repeat the IVF process again.

MCRM Fertility helps you avoid the extra costs of repeating fertility medication and egg retrieval by selecting the best quality embryo ; thus, reducing costs of unsuccessful embryo transfers. This efficient selection can save money and time, so you can focus on preparing for your child.
