Frozen Embryo Transfer: A type of IVF Treatment

Frozen Embryo Transfer

Patients should be aware that around 50% of them will have embryos suitable for freezing. In most cases, the maximum storage time is ten years; however, this may be increased under specific conditions. In best IVF Centre in Delhi NCR, around 85% of embryos can survive the freezing and thawing procedure and remain viable. 

Why do embryos need to be frozen?

Many people choose to freeze their embryos for a variety of reasons.

  • It eliminates the need for many “fresh” IVF/ICSI cycles, as well as the ovarian stimulation and egg retrieval that go along with them.
  • There is no need for you to undergo another ovarian stimulation procedure. As a consequence, there may be less medicine and less stress.
  • You may save your embryos for future pregnancies by freezing them.
  • Before implantation, you may do pre-implantation genetic testing on the embryos to screen for common chromosomal problems.
  • Embryo freezing may be necessary to enable the uterine environment to return to normal before implantation, which doctors may prefer. By allowing the embryo to develop in its natural environment, waiting may help enhance the odds of becoming pregnant.
  • It might save money. Repeated ovarian stimulation may be more costly than several transplants.
  • Because fertility decreases with age, storing embryos while you’re young may help you increase your chances of becoming pregnant later in life. For people who aim to start a family in their 30s, this is very important.
  • Patients at risk for ovarian hyperstimulation syndrome may be advised to undergo frozen embryo transfer procedure.
  • You may have to cancel a fresh embryo transfer due to an unavoidable circumstance, such as a sickness, the flu, etc.

What is the procedure for doing this?

After the uterine lining has been appropriately prepared, frozen embryos are thawed and placed in the womb. This cycle does not need the stimulation of your ovaries or the collecting of eggs, as the embryos have already been implanted. If you are emotionally and physically ready, a frozen embryo transfer treatment cycle may be performed at any time after your first treatment. An appointment with an embryologist or a doctor is required if your first time was undergoing this procedure.

Natural or hormone-regulated cycle? 

You may thaw and transfer embryos frozen in the natural and hormone-regulated cycles. However, each therapy has its advantages and disadvantages. Frozen embryo transfer in the clinic is performed mainly in hormone-regulated cycles. Here, your ovaries are “turned off”, and oestrogen and progesterone hormones are administered to help prepare the lining of your uterus for pregnancy. During the first 12 weeks of pregnancy, the hormones are maintained.

A natural cycle of frozen embryo transfer might be appropriate if you are known to ovulate regularly and on your own. You won’t have to take any hormones because of this. It is impossible to predict when ovulation will occur during a natural cycle; therefore, your embryo transfer may take place on a day when doctors are unable to treat you. You may not be able to proceed with your embryo transfer in that cycle. Even though this is disheartening, the embryos are unaffected since they haven’t been thawed.

How Long Does a Frozen Transfer Cycle Take?

The duration of a frozen embryo transfer cycle is between three and four weeks. Your uterine lining will be prepared for implantation throughout the first two weeks of your pregnancy. In the third week, when your lining is ready, you’ll start taking progesterone supplements. After 3 or 5 days of progesterone support, embryo transfer occurs.
