If there is no sensation in the vagina, it is clinically important to rule out the possibility of a herniated lumbar disc. Since a herniated lumbar disc may compress the vulva, or the nerves in the vagina, which would cause a local loss of perception, a CT examination is recommended. In case of pelvic tumor compression, which can also cause no sensation in the vagina, an ultrasound is recommended to find out if there is a tumor in the pelvis. In addition, if the estrogen is low and the ovarian function is low, this condition can also lead to no vaginal sensation. Therefore, it is recommended to have a blood test for sex hormone 6 on the 2nd day of menstruation, mainly to understand whether the ovarian function and estradiol are normal, and then give the necessary treatment according to the results clinically. It is recommended to wear loose underwear to ensure local blood circulation in the vulva.
