Embryo transfer ( Fresh/Frozen)

Embryo Transfer (Fresh vs. Frozen)

The Final Step of IVF – Carefully Timed, Precisely Performed

Embryo transfer is a key stage in the IVF process where a fertilized embryo is placed into the woman’s uterus. Depending on the treatment plan and medical factors, the embryo may be transferred either fresh (immediately after fertilization) or frozen (cryopreserved and transferred later).

🧬 Fresh Embryo Transfer

• When: Done 3 to 5 days after egg retrieval and fertilization

• How: The best-quality embryo(s) are selected and transferred during the same cycle

• Ideal For:

  • Women with regular cycles

  • Good endometrial lining

  • No risk of ovarian hyperstimulation syndrome (OHSS)

✅ Pros:

• Shorter treatment timeline

• No need to wait for a new cycle

⚠️ Cons:

• Hormone levels during stimulation may affect uterine receptivity

• May increase OHSS risk in high responders

❄️ Frozen Embryo Transfer (FET)

• When: Embryos are frozen after IVF and transferred in a later, natural or hormone-controlled cycle

• Why Choose FET:

  • To allow the body to recover from ovarian stimulation

  • When the endometrium wasn’t ideal in the fresh cycle

  • For genetic testing (PGT-A)

  • To reduce risk of OHSS

✅ Pros:

• More flexibility in timing

• Potentially better implantation rates

• Safer for women at risk of OHSS

⚠️ Cons:

• Slightly longer process due to delay

• Requires thawing and re-evaluation of embryo viability

🧡 How Embryo Transfer Works (Both Fresh & Frozen)

1. Embryo Selection: Best quality embryo is chosen

2. Procedure: A thin catheter is used to place the embryo in the uterus under ultrasound guidance

3. No Anesthesia Needed: It’s quick and painless

4. Post-Transfer Care: Medications to support implantation and a pregnancy test after 12–14 days

🌈 Which Option Is Right for You?

The choice between fresh and frozen embryo transfer depends on:

• Age and hormonal response

• Quality and number of embryos

• Uterine lining readiness

• Presence of any risk factors like OHSS

Every embryo holds the promise of life.
Whether fresh or frozen, we make sure it’s placed with the utmost care, at the right time—for the best chance at success.
