Expensive IVF Drug with No Proof? What You Need to Know About Atosiban

Patient: Dr Malpani, this has been a really tough journey. My last embryo transfer didn’t work, even though everything looked perfect — great embryo, perfect lining. I just don’t understand why it failed.

Dr. Malpani: I completely understand how frustrating that can be. In fact, failed embryo implantation is one of the most perplexing parts of IVF today. You do everything right — you have a top-quality embryo and a thick and receptive endometrium — and yet the embryo doesn't implant. Sadly, this remains a black box in reproductive medicine. We know it happens, but often, we don’t know why.

Patient: But isn’t there anything doctors can do to improve implantation? I heard some clinics are giving a drug called atosiban before embryo transfer to stop uterine contractions. Does that really help?

Dr. Malpani: That’s a great question, and it’s something many patients are now asking. The logic behind Atosiban seems appealing — it’s supposed to block uterine contractions by inhibiting oxytocin, the hormone responsible for contractions. The theory is that during embryo transfer, inserting the catheter might stimulate contractions, and those contractions could "push out" the embryo.

Patient: Right, that’s what my previous doctor said. It made sense at the time — keep the uterus calm so the embryo can implant properly.

Dr. Malpani: Yes, and that’s exactly why so many doctors are using it. The reasoning sounds scientific. But the truth is — just because something sounds logical doesn’t mean it’s true in clinical practice.

Patient: So you're saying it doesn't really work?

Dr. Malpani: Correct. Here's the key point: when we’re doing an embryo transfer, the woman isn’t pregnant yet. The uterus at this stage — what we call a gynaecological uterus — doesn't have the same number of oxytocin receptors as it does during pregnancy. So even if you block oxytocin with Atosiban, it likely won’t have any meaningful effect because the uterus isn’t in a contraction-prone state to begin with.

Patient: Then why is it still being prescribed? Atosiban is expensive!

Dr. Malpani: That’s the unfortunate part. This drug is being heavily marketed by pharmaceutical companies, and doctors — wanting to “do something more” to help their patients — are often quick to try new treatments, especially when a few patients get pregnant after using them. But that doesn't mean the drug caused the pregnancy. Correlation isn’t causation.

Patient: That makes sense. But I think patients like me often just want to do everything possible — even if it’s just for peace of mind.

Dr. Malpani: Absolutely. And that’s what makes this so tricky. When a patient hears, “This might help,” they want to believe it. And when a doctor says, “Let’s try this new drug,” it feels like progress — like we’re leaving no stone unturned. But that hope can be misused, especially when it’s not backed by science.

Patient: So, are there any risks to taking Atosiban?

Dr. Malpani: Medically, it's a fairly safe drug. But the real risk is emotional and financial. It gives you false hope and drains your resources. And when the cycle still fails — as it often does even with Atosiban — you’re left not just heartbroken but also confused and questioning everything. That loss of trust is damaging.

Patient: Wow. And I bet if one patient gets pregnant after Atosiban, that becomes the "proof" it works?

Dr. Malpani: Exactly. Doctors start convincing themselves it's effective. They may even be invited to speak about it at conferences sponsored by the pharmaceutical companies. Other doctors attending the talk start using it, and the myth spreads — not because of solid evidence, but due to clinical anecdotes and marketing.

Patient: So what should a patient like me do instead?

Dr. Malpani: Focus on evidence-based care. Ask your doctor, “What is the actual success rate of this treatment?” and “Is this backed by solid clinical trials?” If it’s not — you’re within your rights to decline it. IVF is expensive and emotionally draining. Don't let anyone pressure you into unproven add-ons.

Patient: Thank you for your honesty, Dr Malpani. I feel so much clearer now. I wish more doctors would explain things this openly.

Dr. Malpani: You’re welcome. My job is not just to treat you but to educate and empower you. You deserve clarity, transparency, and respect in your IVF journey.
