Patient's question:
I am 36 years old this year, with irregular menstruation, which has lasted for a year. I will have my period if I take progesterone, but I won't if I don't.Doctor's answer:
The reasons for the absence of menstruation may be due to a deficiency in any of the links of the hypothalamus-pituitary-ovary axis, or the underdevelopment of the uterus itself. Some girls may also experience pseudomenorrhea or cryptomenorrhea due to congenital defects or postnatal damage in the lower reproductive tract, such as the cervix, vagina, hymen, labia, etc., leading to obstruction or adhesion. Although menstruation occurs, it cannot flow externally. Therefore, it is even more important to carefully identify the cause and treat it promptly.
