"Breast lobular hyperplasia" is a common breast disease among middle-aged women. Data shows that women who had their first child after the age of 30, have never given birth, did not breastfeed after childbirth, had multiple abortions, or have infrequent sexual activity, have a higher incidence of breast hyperplasia. It can be seen from this that there is still a very close relationship between breast lobular hyperplasia and sexual activity.
