The most likely defect to happen in a missed abortion
is a chromosomal anomaly. This need not repeat in the future pregnancies. Adequate folate
intake and proper guidance help a lot. Please avoid another pregnancy
for at least 3-4 months after the abortion. Genetic counselling
could be needed if there is a family history or if repeated abortions occur. TORCH titres and other investigations may be done as needed. Hope you find this information useful. Wish you good health.
