Function of the male sex organs in heroin and methadone users.

The function of the secondary sex organs was found to be markedly impaired in 29 participants in a methadone maintenance program. The ejaculate volume and seminal vesicular and prostatic secretions were reduced by over 50 per cent in methadone clients, as compared to 16 heroin addicts and 43 narcotic-free controls. Serum testosterone levels were also approximately 43 per cent lower in methadone clients than in controls or heroin users. Although the sperm count of methadone clients was more than twice the control levels, reflecting a lack of sperm dilution by secondary-sex-organ secretions, the sperm motility of these subjects was markedly lower than normal. On all measures of secondary-sex-organ and testicular function, heroin addicts appeared to fall between the methadone and control subjects, but, with the exception of sperm motility, the deviation from control values did not reach statisitcal significance.

Sexual function and vaginal anatomy in women before and after surgery for pelvic organ prolapse and urinary incontinence.

OBJECTIVE: We sought to describe sexual function in women before and after surgery for either prolapse or urinary incontinence, or both. STUDY DESIGN: Women completed questionnaires, and vaginal dimensions were measured before and at least 6 months after surgery for prolapse or incontinence. Comparisons were made with signed-rank tests or the McNemar test. RESULTS: Eighty-one (49%) of 165 women were sexually active before and after surgery; their mean age was 54. 0 +/- 9.9 years. Mean frequency of intercourse did not change. Dyspareunia was reported by 6 (8%) women preoperatively and 15 (19%) women after surgery; dyspareunia persisted postoperatively in 1 woman, developed in 14, and resolved in 5 (P =.04). Dyspareunia occurred in 14 (26%) of 53 women after posterior colporrhaphy (P =. 01) and in 8 (38%) of 21 women who had Burch colposusupension and posterior colporrhaphy performed together (P =.02). Vaginal dimensions decreased slightly after surgery; however, this did not correlate with any change in sexual function. Preoperatively, 66 (82%) women were satisfied with their sexual relationships, compared with 71 (89%) who were satisfied postoperatively. CONCLUSION: Sexual function and satisfaction improved or did not change in most women after surgery for either prolapse or urinary incontinence, or both. However, the combination of Burch colposusupension and posterior colporrhaphy was especially likely to result in dyspareunia.

The G-spot: a modern gynecologic myth.

The G-spot is an allegedly highly erogenous area on the anterior wall of the human vagina. Since the concept first appeared in a popular book on human sexuality in 1982, the existence of the spot has become widely accepted, especially by the general public. This article reviews the behavioral, biochemical, and anatomic evidence for the reality of the G-spot, which includes claims about the nature of female ejaculation. The evidence is far too weak to support the reality of the G-spot. Specifically, anecdotal observations and case studies made on the basis of a tiny number of subjects are not supported by subsequent anatomic and biochemical studies.

Reproductive ability of workmen occupationally exposed to lead.

The reproductive ability of 150 men occupationally exposed to lead were studied by clinical and toxicological analysis. Subjects were divided into four groups: lead-poisoned workmen (23) and those showing a moderate (42), slight (35), or physiologic absorption (50). Findings show that (1) Lead poisoning as well as moderate increased absorption of lead decrease the fertile ability of men. An increased frequency of asthenospermia, hypospermia, and teratospermia have objectified the decrease. (2) Slight increased or physiologic absorption of lead do not significantly influence the fertile ability of workmen. (3) Hypofertility induced by lead is due, perhaps, to its direct toxic effect on the gonads, as no interference with the hypothalamopituitary axis were evidenced.

Actual and desired duration of foreplay and intercourse: discordance and misperceptions within heterosexual couples.

One hundred and fifty-two heterosexual couples reported their actual and ideal duration of foreplay and intercourse, as well as their perceptions of their partners' desired duration of foreplay and intercourse. Further, participants reported the duration of foreplay and intercourse that they felt most men and most women wanted. Ideal length of foreplay did not differ for men and women. However, men reported a significantly longer ideal duration of intercourse than did their partners. The ideal duration of foreplay and intercourse were significantly longer than the actual duration for both genders. The women, but not the men, significantly underestimated their partners' desired duration of foreplay and intercourse. Further, both genders exhibited faulty stereotypes concerning men's but not women's ideal scripts. Men were seen as desiring a significantly shorter duration of foreplay and intercourse than the ideal reported by the men in the study. Both men's and women's perceptions of their partners' ideal duration of foreplay and intercourse were found to be more strongly related to their own sexual stereotypes than to their partners' self-reported sexual desires, suggesting that people rely on sexual stereotypes when estimating their partners' ideal sexual scripts. Men's and women's ideal scripts and men's and women's sexual stereotypes concerning the opposite gender's ideal duration of foreplay were found to uniquely predict the foreplay performance script. For intercourse, men's and women's ideal scripts and men's stereotypes concerning the duration of intercourse that women want uniquely predicated the performance script. We present potential reasons for the discrepancy in individuals' performance and ideal scripts.

Gender differences in the content of cognitive distraction during sex.

This study compared 220 college men and 237 college women on two types of self-reported cognitive distraction during sex, performance- and appearance-based. Affect, psychological distress, sexual knowledge, attitudes, fantasies, experiences, body image, satisfaction, and sexual function were assessed with the Derogatis Sexual Functioning Inventory and the Sexual History Form to determine associations with distraction. Between-gender analyses revealed that women reported higher levels of overall and appearance-based distraction than did men, but similar levels of performance-based distraction. Within-gender analyses revealed that women reported as much of one type of distraction as the other, while men reported more performance- than appearance-based distraction. In women, appearance-based distraction was predicted by negative body image, psychological distress, and not being in a relationship, while performance-based distraction was predicted by negative body image, psychological distress, and sexual dissatisfaction. In men, appearance-based distraction was predicted by negative body image, sexual dissatisfaction and not being in a relationship, while performance-based distraction was predicted by negative body image and sexual dissatisfaction. Investigating the content of cognitive distraction may be useful in understanding gender differences in sexual experience and in refining cognitive components of sex therapy.
