Patient's question:
Age: 23Description of Problem: For several years, I have experienced bleeding symptoms outside of my menstrual period. Sometimes the blood is dark brown. Is this a symptom of luteal insufficiency? I would like to ask for detailed symptoms, causes, or factors related to luteal insufficiency, as well as its effects. Is it highly likely to cause infertility? Does it have any relation to breast health?
Doctor's answer:
Luteal atrophy is a type of ovulatory dysfunctional uterine bleeding. The main symptoms are continuous bleeding during menstruation, prolonged duration, and generally normal cycles. The primary issue is insufficient luteal function, specifically inadequate levels of progesterone to maintain the second half of the menstrual cycle. It can affect pregnancy, primarily because the fertilized egg needs sufficient luteal progesterone to firmly implant in the uterine lining after ovulation. This mainly impacts the stability of implantation, making early bleeding and miscarriage more likely. Regarding the irregular bleeding outside of your period, it's unclear which phase it occurs in. If it matches the above description, you should start using progesterone injections (10-20mg) once daily, beginning 8-12 days before your expected period. It's not significantly related to breast health.
