Polycystic, also known as polycystic ovary syndrome (PCOS), is also known as menstruation. In PCOS, menstruation will not come due to the disruption of sex hormone secretion in the body. Patients with polycystic ovary syndrome have multiple small follicles growing and developing on both ovaries, but these follicles are not mature enough to be normally discharged from the ovaries, and the body’s secretion of progesterone is reduced, while menstruation requires not only estrogen, but also progesterone, and when the body loses the role of progesterone, it will lead to lack of menstruation. If polycystic ovary syndrome is not treated in time, it will affect the normal menstrual cycle of women, resulting in scanty menstruation, amenorrhea, and some women have dribbling after menstruation and disturbed menstrual cycle. Polycystic ovary syndrome not only affects women’s menstruation, but also affects ovulation, lowering the probability of conception, so it is important to go to the hospital in time for targeted treatment.
