After the follicle ruptures, it enters the luteal secretion phase. When luteal cysts need to subside, they usually need to have a normal menstrual period and will be completely eliminated when they are reviewed 3-5 days after menstruation. Because luteal cysts are affected by changes in the body’s hormone levels, such as progesterone, they must wait until progesterone has completely withdrawn for menstruation before they can recover and disappear. Do not be overly nervous and anxious, because even if a cyst is formed in the corpus luteum, it is a physiological cyst that may exist in most women clinically, and it will recover after a period and will not affect normal reproductive function. However, if it persists 3-5 days after the end of menstruation, it is recommended to exclude any pathological factors, possibly not the corpus luteum, and tumor marker examination is needed to determine if there is any abnormality according to the situation.
