what is corpus luteum - #19084

I’ve been learning about the menstrual cycle and came across the term corpus luteum, but I’m not entirely sure what it is or how it functions in the body. Could you explain in detail what the corpus luteum is, how it forms, and what role it plays in the reproductive cycle? From what I understand, the corpus luteum is a temporary structure that forms in the ovary after ovulation. How does the corpus luteum form, and why is it important for maintaining pregnancy if fertilization occurs? What hormones does the corpus luteum produce, and how do they support the early stages of pregnancy? What happens to the corpus luteum if pregnancy does not occur? I’ve heard that it eventually degenerates if there’s no fertilized egg to implant in the uterus, but how does this affect hormone levels, particularly progesterone? How does the decline in progesterone lead to menstruation? How do doctors monitor the corpus luteum in cases of infertility or early pregnancy? Are there any conditions or disorders, such as luteal phase defect, where the corpus luteum doesn’t function properly, and how are these issues treated? What symptoms or signs might indicate a problem with the corpus luteum? For example, can an issue with the corpus luteum contribute to irregular periods, difficulty getting pregnant, or early miscarriages? How do doctors diagnose these problems, and what treatments are available to support corpus luteum function? Lastly, can lifestyle factors like stress, diet, or exercise affect the health of the corpus luteum? Are there ways to support hormone balance during the luteal phase of the menstrual cycle, and how can I improve my reproductive health overall?
