When considering IVF (In Vitro Fertilization), one of the key decisions couples face is choosing between Frozen Embryo Transfer (FET) and Fresh Embryo Transfer. Both methods have their advantages and specific considerations, making it essential to understand which option is best for your fertility journey. If you're looking for the best IVF centre in Delhi, clinics like Shivam IVF offer both procedures with expert guidance to maximize your chances of a successful pregnancy.
Understanding Fresh Embryo Transfer
A Fresh Embryo Transfer occurs shortly after the egg retrieval process, typically within 3–5 days. Here’s how it works:
- The eggs are retrieved and fertilized in the lab.
- The best-quality embryos are selected for immediate transfer into the uterus.
- Any remaining embryos can be frozen for future use.
Advantages of Fresh Embryo Transfer
- Shorter treatment cycle: Since the embryo is transferred immediately, there's no waiting period.
- Natural timing: Some believe transferring fresh embryos may better align with the body's natural reproductive process.
- No freezing risks: Although freezing technology has improved, some embryos may not survive the thawing process.
Disadvantages of Fresh Embryo Transfer
- Higher risk of ovarian hyperstimulation syndrome (OHSS): If the woman’s ovaries are overstimulated during ovarian stimulation, it may affect implantation success.
- Lower pregnancy rates in some cases: Studies suggest that fresh embryo transfers may have slightly lower success rates compared to frozen transfers.
Understanding Frozen Embryo Transfer (FET)
A Frozen Embryo Transfer involves freezing embryos for later use, usually in a future menstrual cycle. Here's how it works:
- After egg retrieval, embryos are frozen using advanced cryopreservation techniques.
- In a later cycle, the frozen embryos are thawed and transferred to the uterus.
Advantages of Frozen Embryo Transfer
- Higher pregnancy success rates: Recent studies show that FET has slightly higher success rates compared to fresh transfers.
- Lower risk of OHSS: Freezing embryos allows hormone levels to stabilize before implantation, reducing the risk of OHSS.
- Better uterine receptivity: A woman’s uterus may be more receptive in a natural cycle rather than immediately after ovarian stimulation.
- Flexibility: Allows couples to plan for a pregnancy at a time that suits them best.
Disadvantages of Frozen Embryo Transfer
- Longer wait time: Couples must wait for a future cycle to proceed with implantation.
- Freezing risks: Although rare, some embryos may not survive the thawing process.
Which Option Is Better?
The choice between FET and fresh embryo transfer depends on multiple factors, including age, embryo quality, and underlying fertility conditions. Many fertility specialists at Shivam IVF, one of the best IVF centres in Delhi, recommend FET due to its higher success rates and reduced risks. However, for some couples, fresh transfers may be a suitable option, especially if the conditions for implantation are optimal.
Consulting a qualified fertility specialist is essential to determine the best course of action based on your unique situation. Whether you choose fresh or frozen transfer, Shivam IVF provides advanced reproductive care to help you achieve your parenthood dreams.
