Women's perception of male erectile dysfunction drugs in the general population.

The aim of this study is to investigate trends in women's perception of male erectile dysfunction (ED) drugs in the general population.We designed an online questionnaire survey and randomly invited an initial total of 2370 women to respond to it from a database population that included 450,000 men and women recruited through an Internet-based market research company. The 17 items of the questionnaire comprised 9 items related to socio-cultural background and 8 items related to the perception of ED drugs, ED itself, and sexual relations.A total of 1262 women (53.2% of those initially invited), ranging in age from 20 to 77 years, participated. Among the participants, 83.3% were aware of the existence of ED drugs, but only 12.0% showed some interest in them, 46.4% and 43.2% of the participants claimed to have an unfavorable image of ED drugs, and of men using ED drugs, respectively. Among the participants, 45.2% stated that if their partners suffered from ED at present or in the future, they would not desire their partners to use ED drugs, and 25.5% stated that they would not accept it. Multiple logistic regression analysis revealed that higher age had a negative impact on knowledge, interest and image of ED drugs, the image of men using ED drugs, and the importance of sexual relations.Our findings reveal that a high proportion of women have a negative perception of ED drugs and associated issues in Japan.
