Fresh vs Frozen Embryo Transfers: Why Frozen Gives You a Better Chance at IVF Success

Patient:Dr Malpani, I keep hearing about fresh and frozen embryo transfers. Honestly, I’m confused. What’s the real difference?

Dr Malpani: That’s a great question. In the early days of IVF, all transfers were fresh. We stimulated the ovaries, retrieved eggs, created embryos, and transferred them back in the same cycle.

Patient: That sounds quick and efficient. So why did things change?

Dr Malpani: Because efficiency doesn’t always mean effectiveness. In a fresh cycle, your ovaries are flooded with hormones to produce many eggs. This makes oestrogen levels shoot up — sometimes 10 times higher than normal. While that’s good for egg production, it actually makes the uterus less receptive to the embryo.

Patient: You mean even if the embryo is good, it may not implant?

Dr Malpani: Exactly. Implantation isn’t just about the embryo; it also depends on the uterine lining being ready. When oestrogen is too high, that balance is disturbed.

Patient: So how does a frozen transfer help?

Dr Malpani: With frozen transfers, we separate the two steps. First, we create and vitrify the embryos. Freezing today is so advanced that survival rates after thawing are almost 100% in a good lab. Then, in the next cycle, we focus only on preparing your uterus with just the right hormones. This calm, controlled environment makes the uterus far more receptive.

Patient: So freezing actually improves my chances of success?

Dr Malpani: Yes, in most cases frozen transfers are safer, more predictable, and give better pregnancy rates than fresh ones. It’s one of the biggest improvements in IVF over the last decade.

Patient: That’s really reassuring. I was worried frozen meant lower quality, but now it makes sense why it’s actually better.

Dr Malpani: Exactly. The goal is to give both the embryos and your uterus the best possible conditions. The more you understand, the more confident you’ll feel during treatment.

Patient: Thank you, Dr Malpani. This clears up a lot of my confusion.
