After pregnancy, vibrating masturbators should not be used because during the first 3 months and last 3 months of pregnancy, whether it is sexual activity or using masturbators, it may stimulate uterine contractions, leading to the possibility of miscarriage and premature birth in clinical practice.

If a masturbator is used during mid pregnancy, improper use of the vibrator can cause strong stimulation and lead to miscarriage, resulting in placental abruption or symptoms of threatened miscarriage. If the vibrating masturbator is not cleaned due to lack of hygiene, it may lead to infection of pathogens and inflammation of the reproductive tract, causing serious consequences in clinical practice. Therefore, vibrating masturbators should not be used after pregnancy.

In addition, even if sexual activity is possible during mid pregnancy, it is particularly important to note that sexual movements must be gentle and the frequency of sexual activity should not be too high.
