Frozen Embryo Transfer In Mumbai

What is Frozen Embryo?

The process of freezing an embryo in the lab for future use is called embryo freezing. It is done through cryopreservation, in which the water in the embryo is replaced with cryoprotectant, a medium to avoid crystallization of embryo fluid while preserving it at very low temperatures.

What is Frozen Embryo Transfer?

Healthy eggs are retrieved from a woman’s body. Then through the IVF process, embryos are produced,  developed to a stable stage, tested for chromosomal abnormality, and cryopreserved for future use. Finally, when the couples want to get pregnant, the embryos are thawed and tested for any chromosomal abnormality, and then, a healthy embryo is implanted in the uterus using a catheter and very fine forceps instruments.

Typically multiple embryos are formed to test and implant a healthy embryo via frozen embryo transfer in Mumbai. Often the embryos are products of the previous IVF cycle of either the same or different couples.

Steps In Frozen Embryo Transfer In Mumbai

Frozen Embryo transfer (FET) comprises the following steps:

Step 1 : Monitoring of follicular development

Ovulation is tracked, and the day implantation date is ascertained with sonography, scans, and blood test. These tests will continue until ovulation is properly documented. 

Step 2 : Monitoring Luteinizing Hormone(LH) surge

As the follicles or egg matures, the LH levels in the blood and correspondently in urine will increase automatically. It is crucial to calculate the correct time for embryo implantation.

Step 3 : Tracking ovulation

It is important to track ovulation with sonography and other tests because embryo implantation will fail if ovulation is not timely. In addition, tracking ovulation is important because the uterus releases the natural hormone progesterone that increases the inner width of the uterus and prepares it for implantation or conception. Hence, tracking ovulation will help experts calculate the exact date of implantation.

Step 4 : Embryo transfer

The embryos are thawed on the same day of implantation and implanted in uterine walls by gently holding the embryo in the catheter and passing it through the cervix to uterine walls.

Step 5 : Hormonal supplements and trigger Injection

Not all, but some cases may require progesterone supplementation due to ovulatory dysfunction or luteal phase ( phase between ovulation to pregnancy or menstruation ) inadequacy. The progesterone injections are given until pregnancy is confirmed.

Step 6 : Pregnancy test

Finally, a pregnancy test is conducted on the 15 or 16 th day of implantation. Once it is confirmed, your fertility experts plan for further pregnancy care. However, you might require to perform multiple cycles before falling pregnant.

Success Rates of Frozen Embryo Transfer In Mumbai?

FET techniques use the vitrification (ultra-rapid process of cryopreservation) method, which has an increased success rate of live birth via FET culture. Earlier, FET techniques were not so developed and produced very few vital frozen embryos. However, modern technological advancement has significantly improved results through IVF, IUI, and FET procedures used for assistive reproduction, with much lesser conception failure and miscarriage chances.
