Why IVF Failure?

A Complete Guide to Understanding Why IVF Failure.

IVF failure can happen even when everything seems normal. It often occurs due to hidden issues with embryo quality, uterine environment, or timing of implantation.

Embryo quality plays one of the most critical roles in IVF success. Even when embryos appear healthy under a microscope, they may carry genetic abnormalities that prevent implantation or cause early miscarriage.

Implantation Failure Reasons

Implantation occurs when the embryo attaches to the uterine lining. This process depends on perfect timing between embryo development and endometrial receptivity.

Immune System Issues

Some research suggests that immune reactions may prevent implantation.
