Patient's question:
Hello! I got pregnant for the first time at the beginning of this year. At 6 weeks, there was a fetal heartbeat and fetal bud, but by week 9, the embryo stopped developing without any symptoms.Doctor's answer:
There are many cases of patients in our reproductive center who have had children despite having interstitial translocations, and both males and females are affected. You don't need to be too anxious about it.The interstitial translocation of chromosome 9 you have is a type of polymorphic variation, which has no significant impact on you personally, but it does slightly increase the chances of early miscarriage and embryonic arrest compared to the general population. If a pregnancy can be sustained beyond the fourth month, the risk of congenital defects in the fetus is similar to that of a normal pregnancy. The child may be completely normal or may inherit your interstitial translocation. Each person's karyotype remains unchanged throughout their lifetime, so the risk of early miscarriage and embryonic arrest for you and your partner will always exist.
Although the karyotype remains unchanged throughout life, improving lifestyle, maintaining a balanced diet, and avoiding toxic and harmful environments can still help enhance the quality of your sperm and eggs, indirectly reducing the risk of some early miscarriages and embryonic arrests. Of course, other tests related to embryonic arrest should also be conducted to rule out other causes.
Regarding pre-pregnancy preparation: A woman's egg maturation cycle is approximately 80 days, meaning that the egg released in the current month began growing two and a half months ago. A man's spermatogenesis cycle is three months, so both partners should ideally start preparing three months before trying to conceive. You can begin by adjusting your lifestyle. For example, both partners should drink 2,000–3,000 ml of plain water daily to help detoxify; ensure a sleep schedule of 10 p.m. to 3 a.m. daily and avoid staying up late, as nighttime is the best time for rest and recovery; focus on consuming fresh fruits and vegetables to enhance antioxidant capacity; try to quit smoking and drinking alcohol and avoid toxic and harmful environments; and the woman should take folic acid and vitamins appropriately three months before pregnancy and during the early pregnancy period. The woman should also consider getting a TORCH test before pregnancy to ensure normal results before conceiving.
