Despite decades of study, sexual dysfunction in women remains difficult to measure: UNC researchers
November 18, 2005 | |
Since the 18th century, scientists have been trying to describe the differences between men and women when it comes to relationships, love and sexuality. Women’s lives have been studied worldwide, yet researchers still have very little consistent information about women’s sexual needs, according to researchers at the University of North Carolina at Chapel Hill.”Unlike many other scientific disciplines that are built on sequential research with similar methodologies, studies of women’s sexuality seem to start from ground zero,” said Dr. Suzanne L. West, epidemiology professor in UNC’s School of Public Health. “There has been little consistency in the measures of women’s sexual behaviors, especially sexual dysfunction, so much of the past research cannot be compared and put into context.”
In a paper published in the most recent volume of the Annual Review of Sex Research, West and co-authors Lisa Vinikoor, also of UNC’s School of Public Health, and Dr. Denniz Zolnoun, a physician with the UNC School of Medicine’s department of obstetrics and gynecology, analyzed results of more than 85 studies on female sexual function and dysfunction. Vinikoor is a graduate student in epidemiology, and Zolnoun is a physician affiliated with the UNC School of Medicine’s department of obstetrics and gynecology. The researchers found a huge variation in research methodologies, not only in what questions women in these studies were being asked, but in how they were being asked and who was studied. Early studies focused on women’s sexual satisfaction and orgasm, trying to characterize female sexual response using the same framework as that for males. More recent studies have taken into account that female sexual response may change during the reproductive life cycle and often includes psychological or emotional factors that, while important, are difficult to measure. Many of the studies, perhaps because of methodology or protocol, seem conflicting, which is why it is so important for scientists to have some consistency in the way they conduct their research, West said. For example:
“The more we know about the patterns and severity of sexual dysfunction, the better equipped we will be to find solutions. However, for this field to advance, there needs to be a valid determination of who has sexual dysfunction and what factors influence its occurrence,” West said. “Sexual dysfunction is important to both the woman and her partner, with respect to their relationship. It is also important to society as a whole, as sexual dysfunction and dissatisfaction is reflected in divorce rates, domestic violence, single-parent families and future intimate relationships.” West and Vinikoor also are affiliated with UNC’s Cecil G. Sheps Center for Health Services Research, and West is a part of the UNC Center for Women’s Health Research leadership team and is a faculty member in UNC’s department of obstetrics and gynecology. The Annual Review of Sex Research is published by the Society for the Scientific Study of Sexuality.
