Fertility clinics address cases of recurrent implantation failure (RIF) by employing various strategies aimed at improving outcomes for patients undergoing assisted reproductive technology (ART) processes. Some of the advanced techniques and protocols commonly used include:

1. Pre-implantation Genetic Testing (PGT): This technique involves screening embryos for chromosomal abnormalities before implantation, thus increasing the chances of successful implantation and reducing the risk of miscarriage in cases of RIF.

2. Endometrial Receptivity Analysis (ERA): ERA is a procedure that helps determine the optimal window of implantation by analyzing the receptivity of the endometrium. This personalized approach can be crucial in cases of RIF.

3. Lipidomics and Metabolomics: These advanced techniques involve analyzing the lipid and metabolic profile of the endometrium to assess its receptivity and make necessary adjustments to improve the chances of implantation.

4. Hysteroscopy and Endometrial Scratch: Hysteroscopy allows direct visualization of the uterine cavity to identify and treat any abnormalities that may be hindering implantation. Endometrial scratch is a procedure that triggers a healing response in the endometrium, potentially enhancing implantation.

5. Intrauterine Infusion of Platelet-Rich Plasma (PRP): PRP contains growth factors that can stimulate tissue repair and regeneration. Infusion of PRP into the uterus has shown potential in improving endometrial recept
