There are many reasons for the decrease of progesterone value, among which the more common ones are ovulation disorder, luteal insufficiency, ovarian hypoplasia and so on.
1. Ovulation disorders: for example, polycystic ovary syndrome and hyperprolactinemia may affect ovulation and lead to ovulation disorders, and cause a drop in progesterone.
2. Luteal insufficiency: If a woman’s corpus luteum is not functioning properly, it will lead to the endocrine function being affected, the hormone level in the body will change, and the amount of progesterone secreted will be insufficient.
3. Ovarian hypoplasia: As ovarian function begins to decline, hormone levels in the body change, progesterone decreases, and a shortened menstrual cycle occurs.
Progesterone may also decline due to other reasons, it is recommended to go to the hospital in time to find out the cause and then targeted treatment.
