Question
A woman experienced her first pregnancy at the beginning of the year. At 6 weeks, she had a heartbeat and fetus bud, but at 9 weeks, the embryo suddenly stopped growing without any signs. She inquired about the relationship between chromosomal abnormalities and prenatal abortion.
Answer
Chromosome karyotype is lifelong and unchangeable. The 9th chromosome arm inversion is a polymorphic change that may increase the risk of early pregnancy loss and prenatal abortion. Improving lifestyle and avoiding toxic and harmful environments can help improve the quality of sperm and egg, reducing the risk of early pregnancy loss and prenatal abortion. Prenatal preparation includes adjusting lifestyle, eating a balanced diet, getting enough sleep, and enhancing antioxidant capacity to improve fertility quality.
