RECURRENT MISCARRIAGES/ PREGNANCY LOSSES
Infertility and spontaneous abortions are 2 forms of reproductive failure.
The risk of a spontaneous abortion is 15% to 20% mostly during the first trimester; thereafter, the risk is lower.
30% to 50% of implanted embryos are lost in the first few weeks of pregnancy
Chromosomal abnormalities of the embryo cause more than half of the early losses.
A genetic cause is less likely with late first-trimester or second-trimester losses.
