Can a thin endometrium cause repeated IVF failure?

Yes. A thin uterine lining - typically defined as less than 7 millimetres at the time of embryo transfer — is associated with lower implantation rates and increased IVF failure. The endometrium must be adequately prepared to receive an embryo. When the lining does not thicken despite standard oestrogen preparation, further investigation and additional treatment are needed before proceeding. Options include extended oestrogen priming, intrauterine PRP infusion, and vasodilatory agents. Dr Pallavi Chalasani's existing blog on thin endometrium covers this condition in detail.
