HOW MANY EMBRYOS TO TRANSFER IN IVF: CHENNAI EXPERT GUIDE
If you are planning IVF anywhere in INDIA, one common question couples ask is: how many embryos should be transferred?Choosing the right number of embryos can affect your chances of pregnancy, as well as the health and safety of both mother and baby.
At Iswarya Fertility Centre , Chennai, our team of specialists carefully studies each couple’s age, health, embryo quality, and fertility history to recommend the safest and most effective approach.
This guide explains everything you need to know about embryo transfer in IVF, including factors influencing the decision, risks, benefits, and expert advice.
WHAT IS EMBRYO TRANSFER IN IVF?
Embryo transfer is a key step in the IVF process. After eggs are collected from the woman and fertilised with sperm in the lab, the healthiest embryos are selected.
During the transfer, one or more embryos are gently placed into the woman’s uterus using a thin catheter. Most patients find the procedure painless, and it usually doesn’t require anesthesia. Once transferred, the embryo tries to attach to the uterine lining, which may result in pregnancy.
WHY THE NUMBER OF EMBRYOS MATTERS
The number of embryos transferred can influence:
Pregnancy success rate
Risk of twins or multiple pregnancy
Mother’s and babies’ health
While transferring multiple embryos may seem like a faster route to pregnancy, it can increase complications. Transferring a single embryo reduces these risks, though it may slightly lower the chance of pregnancy in certain cases.
At Iswarya Fertility Centre, Chennai, our approach is personalized. The right number of embryos is decided based on medical evidence, not guesswork.
SINGLE EMBRYO TRANSFER IN CHENNAI
Single Embryo Transfer (SET) involves placing one embryo into the uterus. This approach is increasingly preferred because it offers safety with excellent pregnancy outcomes.
When SET is recommended:
High-quality embryo
Women under 35
First IVF attempt
Couples looking to reduce the risk of twins
Any remaining healthy embryos can be frozen for future cycles, increasing your chances without repeating the full IVF process.
MULTIPLE EMBRYO TRANSFER: BENEFITS & RISKS
Multiple embryo transfer means transferring two or more embryos in one IVF cycle. Some couples consider this to improve success in a single attempt.
Benefits
Increased chance of pregnancy per transfer
Useful for older women or lower-quality embryos
Reduces need for immediate repeat cycles
Risks
Higher chance of twins or triplets
Premature birth or low birth weight
Pregnancy complications (high BP, gestational diabetes)
Emotional, financial, and medical stress
At Iswarya Fertility Centre, Chennai, doctors only suggest multiple transfers when medically necessary.
