Can Endometrial Scratching Boost IVF Success Rates?

Can Endometrial Scratching Boost IVF Success Rates?

When a patient or couple begins an IVF cycle, we are always hopeful that success will be achieved in the very first cycle. Despite excellent pregnancy rates, some patients may require more than one cycle to achieve a healthy pregnancy. Most failed cycles occur because the embryo was genetically abnormal and not healthy enough to develop into a baby. Sometimes other factors play a role, too. For instance, if the uterine lining is not optimized, then it may be more difficult for an embryo to implant. Women who have had multiple failed IVF cycles, despite seemingly good-quality embryos, may be candidates for what we call “endometrial scratching.” Can endometrial scratching boost IVF success rates? Studies suggest that, in women who have failed prior IVF cycles, endometrial scratching appears to improve the implantation rate of a subsequent cycle.

What Is Endometrial Scratching?

Endometrial scratching typically involves performing an endometrial biopsy around day 21 of the menstrual cycle. The biopsy is performed with a very small pipelle (tiny plastic tube) that is inserted through the cervix and into the uterus. A small sample of endometrial tissue is obtained. The procedure often causes cramping, and we recommend taking an over-the-counter pain reliever ahead of time. Endometrial scratching can also be done at the time of a hysteroscopy.

Can Endometrial Scratching Boost IVF Success Rates?

The mechanism behind endometrial scratching is not entirely understood, but we speculate that disrupting the lining of the uterus releases growth factors that help to improve embryo implantation. Patients who have failed two or more IVF cycles seem to benefit the most from this procedure. Some studies suggest that endometrial scratching may be as much as 70% more likely to result in a clinical pregnancy as opposed to no treatment (in patients with more than two prior failed cycles).
