Orgasm without organisms: science or propaganda?

The worldwide epidemic of sexually transmitted diseases (STDs) presents a major public health challenge to medical practitioners and educators as they seek to implement preventive educational strategies in the adolescent population. The serious consequences of many STDs and the insufficient impact of condom promotion in this high-risk group have led to increasing recognition that sexual intercourse is medically unwise for young adolescents. As a result of this recognition, some educators have proposed that adolescent sexuality education focus on the explicit teaching of noncoital sexual activities, sometimes called outercourse. This paper explores the emergence of this educational strategy, the assertion that noncoital sexual activities will positively impact the rising incidence of STDs and unplanned pregnancy in teenagers, and the hypothetical benefits of adolescent noncoital sex.

Naltrexone-induced augmentation of sexual response in men.

BACKGROUND: To ascertain the role of endogenous opioids in sexual response, naltrexone, an opiate receptor antagonist, was administered to men, and its effect on selected self-report measures of sexual response to masturbation was recorded. METHODS: The data are based on results from 20 healthy, sexually active (alone or with a partner) men, aged 20-29 years, who ingested naltrexone (25 mg/day x 3) or placebo in a randomized, double-blind crossover design. There was at least a 14-day interval between drug and placebo treatment. Between 18 and 22 h after the most recent dose of drug or placebo, subjects viewed sexually explicit videos in privacy for 2 h. They were instructed to masturbate and have as many orgasms as desired. The following three different self-report measures of their responses were recorded: number of orgasms; intensity of sexual arousal, and orgasmic intensity. RESULTS: Under the naltrexone condition, the volunteers experienced a significantly greater mean number of orgasms (3.4 +/- 0.2 SEM) than under the placebo condition (2.6 +/- 0.3). The total number of orgasms was 67 under the naltrexone condition and 51 under the placebo condition. At the first orgasm, the measure of intensity of arousal was significantly greater in the naltrexone (3.9 +/- 0.2) than placebo (3.4 +/- 0.2) condition, and the measure of orgasmic intensity was significantly greater in the naltrexone (3.7 +/- 0.2) than in the placebo (3.0 +/- 0.3) condition. CONCLUSIONS: The present study provides evidence that endogenous opioids modulate orgasmic response and the perceived intensity of sexual arousal and orgasm in men. The findings suggest that naltrexone could be clinically useful in cases of inhibited sexual desire and erectile dysfunction.

Relationships among cardiovascular, muscular, and oxytocin responses during human sexual activity.

To determine the psychophysiological correlates of hormonal response during sexual activity, systolic blood pressure (SBP), anal electromyography (EMG), and anal photoplethysmography (APG) were monitored continuously throughout testing in 13 women and 10 men. Each subject completed two or more tests of self-stimulation to 5 min beyond orgasm. Blood samples were obtained continuously for measurement of oxytocin (OT) levels. In both men and women, very high positive correlations were observed between the percentage change in levels from baseline through orgasm of: OT and SBP; OT and EMG intensity prior to and during orgasm; APG and EMG. The number of anal contractions and duration of orgasm were also highly correlated. Two patterns of orgasm were defined by the presence or absence of a quiescent period between orgasmic contractions. EMG and APG amplitudes correlated with the pattern of orgasm. Subjective orgasm intensity correlated significantly with increased levels of OT in multiorgasmic women only. The positive correlations between measures are consistent with a possible functional role for OT in human sexual response.

Group therapy for nonorgasmic women: two age levels.

A group method of therapy was used for the treatment of primary orgasmic dysfunction ten women below and ten women above 35 years of age to determine the appropriateness of this therapy for younger and older females. The treatment combined a Masters and Johnson style of behavioral therapy and self-stimulation therapy. At termination, 70% of the younger women were orgasmic, with 80% orgasmic at 6-month follow-up. Zero percent was coitally orgasmic. Forty percent of the older women were orgasmic at therapy termination, with 60% orgasmic at 6-month follow-up. One women was orgasmic during intercourse. There was general enhancement of the sexual relationship in all participating couples. Group therapy may be less successful for older women, who may be more successfully treated individually.
