Women reported less interest in sex, less pleasure and more pain than men.

In a study of the endocrinology of the perimenopausal years, levels of serum FSH, estradiol (E2), immunoreactive inhibin (INH), testosterone, and sex hormone-binding globulin were measured in a population-based sample of 380 women (mean age, 49.4 yr; range, 45.6-56.9 yr). Subjects were divided into women who reported continuing regular menstrual cycles (27%; group I), a change in menstrual flow without a change in frequency (23%; group II), a change in frequency but no change in flow (9%; group III), changes in both frequency and flow (28%; group IV), and at least 3 months since their last menstrual period (13%; group V). After adjusting for age and body mass index, the geometric mean FSH increased across menstrual groups and, compared with group I, was 53% higher in group IV (P < 0.0005) and 253% higher in group V (P < 0.0001). Age- and body mass index-adjusted geometric means for E2 and INH in group V were 54% and 53% of those in group 1, respectively (P < 0.005, P < 0.0001). Women in group V who did not have a menstrual period in the next year had higher FSH and lower E2 and INH levels than those who subsequently went on to have at least one more menstrual period (P < 0.05). FSH was negatively correlated with E2 (r = -0.30) and INH (r = -0.39), whereas INH was positively correlated with E2 (r = 0.45). We conclude that an increase in serum FSH and decreases in E2 and INH are the major endocrine changes associated cross-sectionally with the menopausal transition.

Introduction People with sexual interests in bondage and discipline, “sadomasochism” or dominance and submission (BDSM) have been seen by many professionals as damaged or dangerous. Aim To examine sexual behavior correlates of involvement in BDSM and test the hypothesis that BDSM is practiced by people with a history of sexual coercion, sexual difficulties, and/or psychological problems. Methods In Australia in 2001–2002, a representative sample of 19,307 respondents aged 16–59 years was interviewed by telephone. Weighted data analysis used univariate logistic regression. Main Outcome Measures Self-reported demographic and psychosocial factors; sexual behavior and identity; sexual difficulties. Results In total, 1.8% of sexually active people (2.2% of men, 1.3% of women) said they had been involved in BDSM in the previous year. This was more common among gay/lesbian and bisexual people. People who had engaged in BDSM were more likely to have experienced oral sex and/or anal sex, to have had more than one partner in the past year, to have had sex with someone other than their regular partner, and to have: taken part in phone sex, visited an Internet sex site, viewed an X-rated (pornographic) film or video, used a sex toy, had group sex, or taken part in manual stimulation of the anus, fisting or rimming. However, they were no more likely to have been coerced into sexual activity, and were not significantly more likely to be unhappy or anxious—indeed, men who had engaged in BDSM scored significantly lower on a scale of psychological distress than other men. Engagement in BDSM was not significantly related to any sexual difficulties. Conclusion Our findings support the idea that BDSM is simply a sexual interest or subculture attractive to a minority, and for most participants not a pathological symptom of past abuse or difficulty with “normal” sex.

The findings of this study suggest that operative intervention in first childbirth carries significant psychological risks rendering those who experience these procedures vulnerable to a grief reaction or to posttraumatic distress and depression.
