What is the cause of low progesterone?

Patient's question:

No

Doctor's answer:

Under normal circumstances, a gestational sac and fetal heartbeat can be observed on ultrasound at 7-8 weeks of pregnancy. Progesterone is a gestational hormone that plays a role in maintaining pregnancy. Low progesterone levels are associated with an increased risk of miscarriage, as well as embryonic developmental abnormalities and luteal function insufficiency of the ovary.
