Repeated Implantation Failure
Causes, Diagnostic Tests & Treatment Options
Repeated implantation failure (RIF) occurs when multiple embryo transfers fail to result in pregnancy despite transferring good-quality embryos. Understanding the underlying causes is essential for improving IVF outcomes.
What is Repeated Implantation Failure?
Repeated implantation failure refers to a condition where embryos fail to implant in the uterus after several IVF attempts. While definitions vary among fertility specialists, it is commonly diagnosed when:
- Three or more embryo transfers fail
- High-quality embryos are transferred but pregnancy does not occur
- No clear cause is identified through routine testing
Common Causes of Repeated Implantation Failure
Embryo Genetic Abnormalities
Chromosomal abnormalities are one of the most common causes of implantation failure.
Uterine Abnormalities
Structural conditions like fibroids, polyps, or scar tissue may prevent embryo attachment.
Endometrial Receptivity Issues
The uterine lining may not be receptive at the time of embryo transfer.
Immune System Factors
Immune responses may interfere with embryo implantation.
Hormonal Imbalances
Hormones such as progesterone must be properly regulated for successful implantation.
Male Factor Infertility
Sperm DNA fragmentation may affect embryo development.
Diagnostic Tests for Repeated Implantation Failure
ERA Test
Evaluates whether the uterine lining is receptive during embryo transfer.
PGT-A Genetic Testing
Tests embryos for chromosomal abnormalities before transfer.
Hysteroscopy
Examines the uterine cavity for structural abnormalities.
Immune Testing
Identifies immune system factors affecting implantation.
Thrombophilia Screening
Detects blood clotting disorders affecting pregnancy.
Sperm DNA Fragmentation
Evaluates sperm DNA integrity.
Treatment Strategies
- Personalized embryo transfer timing
- Genetic embryo screening
- Treatment of uterine abnormalities
- Hormonal therapy adjustments
- Immune system treatment
