Patient's question:
Why does abdominal pain occur after embryo transfer in IVF?Doctor's answer:
After embryo transfer, abdominal pain reappears. First, it is suspected to be threatened miscarriage. The embryo is implanted into the endometrium, and the uterine cavity is affected by foreign substances, leading to reflexive uterine contractions, which is one cause of abdominal pain. Another possible cause is luteal phase defect, which can also result in abdominal pain. This is because, after a normal pregnancy, the ovary forms the corpus luteum to nourish the embryo's growth and development. However, in IVF, the embryo is implanted into the endometrium and can only rely on externally supplied progesterone to nourish itself, which may lead to symptoms of threatened miscarriage. It is recommended that you go to the hospital promptly.
