Patient's question:
What are the symptoms of progesterone deficiency?Doctor's answer:
Luteal phase deficiency refers to a condition where follicular development and ovulation occur during the menstrual cycle, but there is insufficient secretion of progesterone during the luteal phase or premature luteal regression, leading to poor secretory response of the endometrium. It is generally characterized by a shortened menstrual cycle, resulting in menstrual frequency. Sometimes, although the menstrual cycle falls within the normal range, the follicular phase is prolonged and the luteal phase is shortened, making it difficult for patients to conceive or prone to early pregnancy loss.
