Can Pelvic Floor Therapy Improve Sexual Health in Postmenopausal Women? Results from a New Clinical Study
A person’s pelvic floor muscles (the muscles that create a hammock-like structure to hold the body’s pelvic organs in place) can have a noticeable effect on his or her sexual quality of life.
For women, if these muscles are too tight, they may spasm involuntarily and make vaginal penetration painful, a condition known as vaginismus. Alternatively, if a woman’s pelvic floor muscles are too weak, she may experience pelvic floor dysfunction such as urinary or fecal incontinence (leaking urine or stool) and/or pelvic organ prolapse (the descent of a pelvic organ from its normal location and into the vagina). These conditions can make sexual activity painful for women. What’s more, studies have shown that women with weak pelvic floor muscles have more trouble reaching orgasm than those with healthy pelvic floor muscles.
Pelvic floor muscle training (PFMT) is a conservative, low-risk treatment option for mild cases of pelvic floor dysfunction. It involves exercises that target strengthening, relaxing, and generally gaining more control of the pelvic floor muscles. Since pelvic floor dysfunction and sexual dysfunction become more prevalent as women age (and particularly after menopause), the authors of a recent Journal of Sexual Medicine study aimed to investigate how PFMT impacts the sexual function of postmenopausal women.
Seventy-seven postmenopausal women were included in this study, which was conducted at the School Health Center at Ribeirão Preto Medical School – University of São Paulo in Brazil. The participants were split into two groups: the intervention group (40 women) and the control group (37 women).
Those in the intervention group received detailed instructions from two trained women’s health physiotherapists on how to complete a 12-week PFMT protocol. The PFMT exercises, which included holding 10 maximal voluntary contractions for at least 6 seconds each, then completing 5 rapid contractions, were to be done daily in four different positions (sitting, standing, lying down face upward, and on all fours). Twice a week, the women in the intervention group were supervised by the physiotherapists. The women in the control group did not receive any intervention. To assess the women’s sexual function before and after the 12-week period, the researchers used the Female Sexual Function Index (FSFI) questionnaire.
Overall, results showed somewhat contradictory findings. When comparing between groups, the changes from baseline to the 12-week follow-up point were not different between patients receiving treatment or not. However, when analyzed a different way, the group which received PFMT ended up showing a lower rate of sexual dysfunction compared to controls. Based on these findings, the authors concluded that PFMT decreases sexual dysfunction in postmenopausal women. Given the seeming discrepant findings, experts caution against drawing too many conclusions about PFMT without the support of additional, larger studies.
The authors similarly acknowledged that the relatively small sample size was a limitation of the study, as well as the fact that they did not monitor the participants’ medications, some of which might affect sexual function. Furthermore, many members of the intervention group did not return their PFMT adherence assessment diaries at the end of the study, which made it difficult for the researchers to analyze how well the participants adhered to the program. This could be an important aspect of PFMT to study further because poor adherence to any medical intervention can greatly impact patient outcomes.
Nevertheless, the results provide additional information on the potential value of PFMT and suggest that therapy may provide some benefits for postmenopausal women with few risks.

What Is Jelqing, and Does It Actually Work?
The term “jelqing” refers to a set of penis stretching exercises that some believe can make the penis bigger. Although the practice has gained attention and popularity in blogs and internet forums in recent years, there is no scientific evidence that it is an effective way to permanently increase the size of one’s penis. In fact, in some cases, jelqing may actually cause damage to the penis, so it is a good idea to get all the facts before setting off to try it.
What Is the Average Penis Size?
If you have ever wondered how your penis compares to others in terms of size, you are not alone. Many men are curious to know how their penises stack up compared to the average. Unfortunately, general curiosity can sometimes give way to full-on obsession and anxiety about penis size. This can be an unhealthy and often unnecessary fixation, especially because most men who think their penises are too small have perfectly normal-sized penises.
What Is Sensate Focus and How Does It Work?
Sensate focus is a technique used to improve intimacy and communication between partners around sex, reduce sexual performance anxiety, and shift away from ingrained, goal-oriented sexual patterns that may not be serving a couple.
