What causes brown discharge during the luteal phase?

Bleeding during the luteal phase accompanied by brownish discharge is usually caused by various factors. It may be ovulation-related bleeding, which occurs due to a temporary drop in estrogen levels during the luteal phase, leading to shedding of the endometrium and subsequent bleeding. Insufficient luteal function can also cause fluctuations in estrogen and progesterone levels, resulting in premature shedding of part of the endometrium and producing brownish discharge. Gynecological conditions such as cervicitis or cervical polyps may also lead to abnormal vaginal bleeding, manifesting as brownish discharge during the luteal phase. To determine the exact cause, it is recommended to seek timely medical evaluation through appropriate examinations, followed by targeted treatment based on the underlying cause. Maintaining a healthy lifestyle and good hygiene practices are also important measures for preventing such conditions.
