Patient's question:
A few days ago, I went to the hospital for a prenatal check-up. The doctor found that my yolk sac was larger than 8mm. My friend told me that a yolk sac larger than 8mm indicates fetal malformation, and I'm very scared. Is a yolk sac larger than 8mm a sign of malformation?Doctor's answer:
The yolk sac has a direct impact on fetal development. After a woman becomes pregnant, the normal size of the yolk sac is between 5 and 6 millimeters. It can be slightly larger, but only within 8 millimeters. If it is larger than 8 millimeters, it can easily cause fetal malformation. However, this statement is not entirely absolute. It is recommended to relax, rest more, regulate the hormone levels in the body, and undergo regular check-ups to see if it returns to normal within a few weeks.
