Patient's question:
Can hypothyroidism cause habitual abortion?Doctor's answer:
Habitual abortion and luteal phase defect are related. This primarily refers to insufficient progesterone secretion by the corpus luteum or premature luteal regression, which leads to poor endometrial secretion. Severe luteal phase defect can also cause difficulties in implantation of the zygote and increase the risk of recurrent miscarriage in the early stages of pregnancy. Therefore, if habitual threatened abortion occurs in the early stages of pregnancy, it is essential to undergo further detailed examination to confirm whether it is caused by luteal phase defect and then actively treat it.
