Eligibility

Inclusion criteria

Inclusion criteria: Age from 21 to 35 years. Women diagnosed with RIF (defined as failure to achieve pregnancy after at least two embryo transfers with high quality embryos). Couples undergoing infertility evaluation and treatment. Both partners providing informed consent for genetic testing.

Exclusion criteria

Exclusion criteria: Women with known uterine abnormalities, thrombophilia, or autoimmune disorders. Cases with chromosomal abnormalities detected in either partner.

Design outcomes

Primary

MeasureTime frame
Prevalence of HLA Class I and II mismatch with KIR genotypes in women with repeated implantation failure, and implantation rate after personalized immunomodulatory treatment in mismatch couplesTimepoint: Time Points: Baseline, 4 weeks, 8 weeks Baseline (before IVF cycle), 4 weeks after embryo transfer (biochemical pregnancy), and 8 weeks after embryo transfer (clinical pregnancy with cardiac activity)

Secondary

MeasureTime frame
1. Distribution of activating & inhibitory KIR genotypes in repeated implantation failures & their association with specific HLA alleles. 2.Implantation rate & Clinical pregnancy rate after personalised treatment in mismatch couples. 3. Comparing the prevalence of HLA-C-KIR mismatch among the fertile controls & RIF patients Timepoint: 1. At baseline 2. At 12 weeks. 3. At study completion
