Frozen Embryo Transfer (FET)

A Second Chance, Precisely Timed

In modern fertility care, freezing embryos is not just a backup plan — it’s a strategic, science-led choice. At Sparsh IVF, Frozen Embryo Transfer (FET) allows us to transfer embryos in a cycle where your body is fully prepared, your hormones are balanced, and your chances are optimized.

Whether you’ve frozen embryos for medical reasons, want to delay pregnancy, or are returning after a failed fresh transfer, FET brings new hope with careful timing and personalized precision.

What Is FET?

Frozen Embryo Transfer (FET) is a process where previously frozen embryos — created through an IVF or ICSI cycle — are thawed and transferred into the uterus in a later menstrual cycle.

This separation of embryo creation and transfer allows:

  • Better synchronization with the endometrial lining
  • Time for recovery after egg retrieval
  • Use of genetically tested (PGT-A) or donor embryos
  • Flexibility for personal or medical reasons

FET has become a preferred method globally due to high success rates, improved embryo survival, and greater control over cycle timing.

When Is FET Recommended?

FET is commonly advised in cases such as:

  • Surplus embryos from a fresh IVF/ICSI cycle
  • Failed fresh embryo transfer
  • PGT-A / PGT-M testing cycles
  • Fertility preservation due to cancer or social reasons
  • High estrogen or progesterone in fresh cycle affecting lining
  • Risk of OHSS (Ovarian Hyperstimulation Syndrome)
  • Couples using donor eggs or donor embryos

At Sparsh IVF, nearly 60–70% of IVF transfers today are done via FET because of its safety and flexibility.

The FET Process at Sparsh IVF

FET can be done in:

  • Natural cycle (for women with regular periods)
  • Hormone replacement cycle (HRT) with estrogen and progesterone
  • Modified natural cycle with ovulation support

Our team decides the best approach based on your hormonal profile, cycle history, and previous response.

  • Daily oral estrogen (or patches) to grow uterine lining
  • Ultrasounds monitor endometrial thickness (ideal: ≥7–8 mm)
  • Once lining is adequate, progesterone support is added
  • Embryo transfer is timed according to embryo age and progesterone exposure
  • Embryos are thawed with a >95% survival rate using vitrification
  • The best-quality embryo is selected
  • The procedure is painless and does not require anesthesia
  • After 10–15 minutes of rest, patients return home the same day
  • Progesterone supplements continue
  • A blood test is done 10–12 days later to confirm pregnancy

Fresh vs. Frozen Transfer: Which Is Better?

Key Differences:

ParameterFresh TransferFrozen Transfer (FET)
TimingSame cycle as egg retrievalLater cycle
Hormone BalanceMay be affected by stimulation drugsMore natural or controlled
Endometrial ReceptivitySometimes suboptimalBetter synchronized
Embryo ScreeningNot possible in freshIdeal for PGT-tested embryos
Risk of OHSSHigherNegligible

Frozen Embryo Transfer Success Rate:

  • Women <35: 60–65%
  • Ages 35–40: 50–55%
  • With PGT-A tested embryos: up to 70%

Our team handles this process with absolute confidentiality and sensitivity.

Benefits of Frozen Embryo Transfer

  • Greater control over cycle timing
  • Improved uterine receptivity
  • Lower risk of hormonal complications
  • Highly successful with donor and PGT cycles
  • Safer for high-risk patients or thin endometrium

Common Concerns About FET

Yes. In fact, recent research shows higher implantation and live birth rates with FET, and fewer complications like preterm labor.

 At Sparsh IVF, we use vitrification, the most advanced freezing method. Our thaw survival rate is consistently above 95%.

Yes — but our team strongly recommends Single Embryo Transfer (SET) in FET cycles to reduce risk of twins or complications.
