Does moxibustion affect ovulation?
Under normal circumstances, properly administered moxibustion based on accurate syndrome differentiation does not affect ovulation and may even assist in regulating it. However, blind use of moxibustion or inappropriate application for certain constitutions may interfere with ovulation. If in doubt, it is recommended to consult a healthcare professional beforehand. Detailed analysis is as follows:

Moxibustion has the effects of warming the meridians, dispelling cold, and regulating qi and blood. For individuals with cold-deficient constitution or impaired ovulation due to stagnation of qi and blood, targeted moxibustion at specific acupoints can improve pelvic blood circulation, warm the uterus, help regulate endocrine function, and create favorable conditions for ovulation—without negatively affecting normal ovulatory processes.
However, individuals with yin deficiency and internal heat or damp-heat accumulation may experience aggravated internal heat due to the warming nature of moxibustion, potentially leading to endocrine disorders and subsequent disruption of ovulation. Additionally, blindly applying moxibustion to abdominal acupoints, overusing it, or undergoing sessions that are too long or too frequent may disrupt the body's balance, impair ovarian function, and cause ovulatory abnormalities.
Moxibustion should be performed only under the guidance of a qualified practitioner who can determine whether one’s constitution is suitable. If discomfort such as menstrual irregularities or excessive body heat occurs after moxibustion, treatment should be stopped immediately and medical advice sought.
