Generally, after the use of Povidon suppositories, the disease is cured and the intercourse is allowed only after one week of discontinuation. Povidon suppositories are mainly used for patients with mycosis fungoides, cervical erosion or senile vaginitis. Sexual intercourse during treatment in such patients can affect the therapeutic effect of the medication and also cause the partner to suffer from infectious diseases at the same time. Therefore, firstly, sex should be performed only after the disease has been cured. Secondly, although the pessary does not contain hormonal substances, it has estrogen-like effects, and after one week of use, it can transform the bottom cells of the patient’s vaginal cells into middle cells and rejuvenate the vaginal mucosa, and sex after one week of discontinuation will not affect this process. In the process of using Povidon suppositories, care should be taken to keep the local pubic area dry and clean to avoid contamination, which may affect the efficacy or aggravate the infection.
