The Osmolality of Sex-the Science of Vaginal Moisturizers and Lubricants.

Abstract

More than half of women report using vaginal lubricants during their lifetime. Despite such ubiquitous use, most healthcare providers don't ask about their use and may not feel comfortable counseling a patient about how to choose the best product. The purpose of this review is to explain the difference between different vaginal products, address the factors that affect the efficacy of vaginal products, and provide evidence on the use of these products for masturbation and the use of sex toys, penile-vaginal intercourse, anal intercourse, and for couples seeking to become pregnant.
