How long after corpus luteum rupture does menstruation occur?
Under normal circumstances, if the corpus luteum rupture is mild, treated promptly, and ovarian function remains unaffected, menstruation usually returns within about one month. However, if the rupture is severe, ovarian function recovers slowly after treatment, or the individual already has an irregular menstrual cycle, the return of menstruation may be delayed to 1–2 months. If there are any concerns, it is recommended to seek medical advice early. Detailed analysis is as follows:

If the corpus luteum rupture is mild and the condition can be controlled with conservative treatment (such as hemostasis and anti-infection measures) without significantly affecting normal ovarian function, and if the person normally has a regular menstrual cycle, the body gradually recovers within one month and the ovaries can normally enter the next physiological cycle. In such cases, menstruation typically resumes within about one month.
If the corpus luteum rupture is severe and requires surgical intervention, causing some trauma to the ovary, ovarian function may take longer to recover postoperatively. Additionally, individuals who already have pre-existing menstrual irregularities may experience further hormonal imbalances due to the body's stress response following the rupture. As a result, the return of menstruation may be prolonged to 1–2 months or even longer. In these cases, close monitoring of menstrual recovery is necessary.
After a corpus luteum rupture, regular follow-up appointments should be conducted as directed by a physician to monitor ovarian function and overall recovery. If menstruation does not resume within more than two months, or if symptoms such as abdominal pain or abnormal bleeding occur, prompt medical evaluation is required.
