Some gynecological examinations, such as the sex hormone six test, can be performed during menstruation, but other gynecological examinations should be avoided during menstruation. Sex hormone 6 test is mainly used to assess the ovarian function and endocrine condition during the follicular phase, and the test is usually conducted on the 2nd to 5th day of menstruation for the most accurate results. Except for the sex hormone 6 test, which can be performed during menstruation, other gynecological tests such as routine urinalysis, routine leukorrhea, HPV screening, and cervical TCT should not be performed during menstruation due to the fact that menstrual blood may affect the results of the test. Meanwhile, the female reproductive system is more fragile during menstruation, and gynecological examinations at this time are prone to infection. If gynecological examination is needed, it is recommended to go to the hospital and under the doctor’s guidance.
