Patient's question:
NoDoctor's answer:
Progesterone is a natural progestogen secreted by the corpus luteum of the ovary. It has a significant morphological effect on the estrogen-stimulated endometrium in the body and is essential for maintaining pregnancy. Progesterone levels gradually increase with gestational age. The minimum normal progesterone level in early pregnancy is 17.2 ng/ml, and the maximum value is 25.8 ng/ml. Low progesterone levels are mainly caused by luteal dysfunction.
