The endometrial scratch is a minor surgical procedure performed before IVF treatment to potentially increase pregnancy success rates. During this intervention, a small catheter creates a controlled injury to the uterine lining, which may trigger a healing response that makes the endometrium more receptive to embryo implantation. While research shows promising results for certain patients, especially those with previous failed IVF attempts, the procedure’s effectiveness continues to be studied by fertility specialists worldwide.
Understanding Endometrial Scratching
Endometrial scratching is a minimally invasive procedure designed to enhance the chances of embryo implantation during fertility treatments. This innovative technique involves creating a minor, controlled injury to the endometrial lining of the uterus, typically performed before an IVF cycle or embryo transfer. The procedure has gained significant attention in reproductive medicine due to its potential to increase pregnancy success rates by up to 20% in certain patient groups. During the procedure, a small catheter is used to create microscopic scratches in the endometrium, triggering a series of biological responses that can improve receptivity to embryo implantation.
Research has shown that endometrial scratching can be particularly beneficial for patients who have experienced repeated implantation failure or those preparing for their first IVF cycle. The procedure is typically performed during the luteal phase of the menstrual cycle, approximately 7-10 days before the expected start of the next period.
The Science Behind Endometrial Scratching
The biological mechanism behind endometrial scratching is based on the body’s natural healing response. When the endometrium is gently scratched, it initiates a complex cascade of cellular events that can enhance the endometrial environment for implantation. This process involves the release of growth factors, cytokines, and other beneficial compounds.
Studies have demonstrated that the procedure can increase endometrial thickness by up to 33%, creating a more optimal environment for embryo implantation. The enhanced thickness and improved blood flow contribute to better endometrial receptivity and increased chances of successful pregnancy.
The key benefits of endometrial scratching include:
- Increased production of adhesion molecules
- Enhanced endometrial vascularization
- Improved synchronization between embryo and endometrium
- Reduction in scarring tissue formation
Inflammatory Response
The controlled injury from endometrial scratching triggers a local inflammatory response that plays a crucial role in improving implantation rates. This inflammation leads to the release of pro-inflammatory cytokines and growth factors that help create an optimal environment for embryo attachment.
The inflammatory process involves several key stages:
- Initial inflammatory response
- Recruitment of immune cells
- Release of growth factors
- Tissue remodeling
- Enhanced endometrial receptivity
Growth Factors and Hormones
During the healing process following endometrial scratching, there is a significant increase in the production of growth factors and hormones. These include vascular endothelial growth factor (VEGF), platelet-derived growth factor (PDGF), and various interleukins that promote tissue repair and regeneration.
The release of these biological compounds leads to:
- Enhanced endometrial blood supply
- Improved tissue regeneration
- Better hormonal response
- Increased endometrial receptivity

The Procedure Process
The endometrial scratch procedure, also known as endometrial injury or endometrial biopsy, is a minimally invasive technique designed to enhance embryo implantation success rates. During this procedure, a specialized physician creates controlled micro-injuries to the endometrial lining using specific medical instruments, triggering a healing response that can improve receptivity to embryo implantation.
Research has shown that this controlled injury initiates a local inflammatory response, releasing growth factors and cytokines that promote endometrial regeneration. Studies indicate that this process can increase endometrial thickness by up to 33%, creating a more favorable environment for embryo implantation.
Timing of the Procedure
The timing of an endometrial scratch is crucial for its success. The procedure is typically performed during the luteal phase of the menstrual cycle, specifically between days 19-24 of the cycle preceding the IVF treatment. This timing ensures optimal endometrial preparation and regeneration before embryo transfer.
Clinical studies have demonstrated that performing the scratch during this specific window maximizes its benefits, as the endometrium is most responsive to the controlled injury during this phase. The healing process typically takes between 2-3 weeks, allowing sufficient time for the endometrial lining to recover and become more receptive.
Optimal Scheduling
For the best results, the endometrial scratch should be scheduled:
- At least one full cycle before the planned IVF treatment
- During the luteal phase (typically days 19-24)
- After ovulation has been confirmed
- When there are no active infections present
What to Expect During the Procedure
The endometrial scratch is performed as an outpatient procedure that typically takes 10-15 minutes. Patients remain fully conscious during the procedure, though mild discomfort may be experienced. The process begins with a speculum examination, similar to a routine gynecological check-up, followed by careful cleansing of the cervix.
Most patients experience minimal discomfort, though some may feel mild cramping during and shortly after the procedure. It’s recommended to:
- Take over-the-counter pain medication 30-60 minutes before the procedure
- Avoid strenuous activity for 24-48 hours afterward
- Monitor for any unusual symptoms or complications
- Stay well-hydrated and maintain normal daily activities
Medical Tools Used
The procedure utilizes several specialized medical instruments:
- Pipelle catheter – A thin, flexible plastic tube used for endometrial sampling
- Speculum – For accessing and visualizing the cervix
- Antiseptic solution – For cleansing the area
- Sterile equipment – Including gloves and cleaning materials
