Patient's question:
The day before my period, progesterone was 0.86—is that normal? If it's the luteal phase? The range for the luteal phase is 5-33. I'm 38 years old and planning to get pregnant.Doctor's answer:
Hello, the normal range of progesterone during non-pregnancy is 5.16-18.56.Advice: Low progesterone indicates luteal phase deficiency, where the corpus luteum fails to secrete sufficient progesterone or degrades prematurely. This leads to poor secretion of the endometrium, making it difficult for the embryo to implant or resulting in early pregnancy loss. It is recommended to first visit a hospital to identify the underlying factors or causes. Then, take progesterone orally or via intramuscular injection for 3-7 days, followed by a recheck of hormone levels. Once progesterone returns to normal, consider pregnancy.
