The success rate of a healthy pregnancy achieved through the Frozen Embryo Transfer (FET) process has increased substantially in recent years. This success has made FETs an increasingly popular option to consider before considering a subsequent fresh IVF cycle.
Frozen Embryo Transfer Process
A FET cycle is one in which the frozen embryos from a previous fresh IVF cycle – or egg donor cycle – are thawed and then transferred to the mother’s uterus for hopeful implantation. Only excess quality embryos are cryopreserved for future FET procedures. With FET, couples can increase their chance of pregnancy per fresh egg retrieval and ultimately save money by avoiding the expense of another fresh IVF cycle.
Higher Pregnancy Success Rates
The FET process does not decrease pregnancy success rates. Recent studies report higher success rates with FET than with fresh embryos. This is because the woman’s body has had time to recover from the physical stress put upon her by fertility medications administered during a fresh IVF cycle.
- FET pregnancy success has improved dramatically over the last several years
- FETs are typically a single embryo transfer after a woman’s body is prepared for pregnancy
- Multiple embryo transfers do not increase a woman’s chances of conception – only the likelihood of a multiple pregnancy
- FET also help couples build balanced families through gender selection.
Dr. Laurence Jacobs’ IVF and FET success rates are based on patient characteristics and treatment protocols.
- Infertility diagnosis
- History of previous pregnancies
- History of previous miscarriages
- Number of failed IVF cycles – fresh and frozen embryo transfers
- Number of embryos transferred in a single cycle
- Type of IVF procedure
- IVF ancillary procedures used – ICSI, Assisted Hatching, In Vitro Maturation
Cutting Edge Vitrification Cryopreservation Technique
Vitrification is the cryopreservation technique used to freeze embryos. Vitrification is a flash-freezing technique that reduces the formation of ice crystals between an embryo’s cells. During the vitrification freezing process, a cryoprotectant is used to protect the embryo from ice crystal formation.
- Ice crystals damage an embryo’s cells
- Vitrification helps embryos achieve a higher rate of survival upon thawing
- Embryos frozen via vitrification – flash freezing – are able to be stored indefinitely
- Survival rate for the freezing and thawing process is 98 percent
Benefits of Frozen Embryo Transfers
- Fertility preservation for future family planning
- Preservation of surplus embryos in case a fresh IVF transfer fails
- Preservation of surplus embryos to allow for future pregnancies after a successful fresh IVF cycle
- Delaying transfer until the woman’s body recovers from her fresh IVF cycle
