The body's physical response to sexual urges is a complex blend of hormones, nerves, and emotional responses. Sounds sexy, doesn't it? When someone experiences sexual dysfunction, it is likely that some component of this complex blend is missing or malfunctioning.
The causes of sexual dysfunction are numerous. In men, an erection relies upon the penis filling with and trapping blood. If there are any underlying circulatory problems like high blood pressure, nerve problems such as neuropathy, or certain conditions including diabetes, a man may not be able to reach an erection.
Since sperm needs the liquid created in the prostate to travel, men who have prostate cancer or who must have their prostates removed may experience problems with sexual function, too. Surgery to remove the prostate often destroys nerves, which may lead to impotence.
In both men and women, hormones are a major ingredient in this complex blend. Testosterone, usually associated with male traits, is actually a requirement for sexual response in both genders. Men going through andropause, a process similar to menopause in women, will have lower levels of testosterone.
Female sexual dysfunction can be caused by physical or psychological issues, or a combination of the two. Physical causes include cystitis, vaginitis, and vaginal dryness. Women who have experienced abuse as a child or as an adult may face difficulties with sexual response. Depression can also be a cause, and stress could also be a contributing factor.
Medications can also contribute to sexual dysfunction. Oral contraceptives and antidepressants are both very common causes of sexual dysfunction.
