Recurrent Miscarriage
Recurrent miscarriage, or repeated pregnancy loss, is medically defined as three or more consecutive miscarriages. However, even if you have experienced one or two losses and wish to understand the cause or reduce the risk of another, Cosmomed is here to support you.

Pregnancy loss is the most common complication of early pregnancy, affecting 25–30% of confirmed pregnancies. The leading cause of miscarriage in the first trimester is chromosomal abnormalities in the fetus, responsible for nearly 50–60% of early losses. These abnormalities usually occur due to random errors as the embryo grows and divides, and the risk increases as the mother’s age rises because egg quality naturally declines.

How can I reduce the risk of miscarriage?
Since many miscarriages occur due to chromosomal issues, one effective approach is Genetic Testing through Comprehensive Chromosomal Screening (CCS). CCS (also known as embryo screening) examines all 24 chromosomes to detect any missing or extra chromosomes, including conditions such as Trisomy 13, Trisomy 18, and Trisomy 21. CCS also assesses the X and Y chromosomes, making gender selection for family balancing possible. By ensuring that only chromosomally normal embryos are transferred, CCS significantly lowers the chance of miscarriage.
How do I know if my miscarriage was due to a chromosomal abnormality?
Chromosomal testing can be performed on the pregnancy tissue (Products of Conception) after a miscarriage. This test helps determine whether a chromosomal issue was the cause. Microarray Chromosomal Analysis—using advanced techniques such as SNP and oligomer evaluation—can detect polyploidy (a common cause of loss, especially in molar pregnancy) and rule out maternal cell contamination. Results are typically available within approximately 7 working days.
