The effects of increasing neutral distraction on sexual responding of women with and without sexual problems.

This study examined the influence of distraction on genital and subjective sexual responses of women with (N=20) and without (N=21) sexual problems. Female-produced erotic film fragments were presented to induce sexual response and a vaginal photoplethysmograph was used to measure genital sexual responding. Subjective sexual arousal was assessed in real time using a rotating button and, retrospectively, with visual analogue scales. Distraction load was manipulated through different verbal instructions on how to deal with pairs of digits. The results revealed an equally strong impeding effect of distraction on genital sexual responses and on subjective sexual responses when these were measured retrospectively in women with and without sexual problems. However, distraction did not affect subjective sexual responses when these were measured in real time. The implications of the finding that distraction equally affects women with and without sexual problems are discussed.

Emotions during sexual activity: differences between sexually functional and dysfunctional men and women.

The present study investigated the differences in emotional response to automatic thoughts presented during sexual activity between sexually functional and dysfunctional men and women. A total of 376 participants (160 women and 120 men without sexual problems and 47 women and 49 men with a DSM-IV-TR diagnosis of sexual dysfunction) completed the Sexual Modes Questionnaire (SMQ male and female versions; P. J. Nobre & J. Pinto-Gouveia, 2000) and measures of sexual functioning: The International Index of Sexual Function (IIEF; R. C. Rosen et al., 1997), and The Female Sexual Function Index (FSFI; R. C. Rosen et al., 2000). The SMQ is a combined measure constituted by three interdependent subscales: Automatic Thought subscale (AT), Emotional Response subscale (ER), and Sexual Response subscale (SR). Emotions were assessed by the ER subscale, where participants endorsed emotional reactions (worry, sadness, disillusion, fear, guilt, shame, anger, hurt, pleasure, satisfaction) to a list of automatic thoughts (AT subscale) that may occur during sexual activity. Results showed that both men and women with sexual dysfunction had significantly less positive emotional reactions to automatic thoughts during sexual activity. Sexually dysfunctional men had significantly more emotions of sadness, disillusion, and fear, and less pleasure and satisfaction, compared to men without sexual problems. Women with sexual dysfunction had significantly less pleasure and satisfaction, and more sadness, disillusion, guilt, and anger. Findings were congruent with recent studies indicating that emotions related to depressed affect (sadness, disillusion, lack of pleasure) as opposed to negative emotions (mostly related to anxiety) were stronger correlates of sexual dysfunction.

Cardiovascular risks of sexual activity.

The risks associated with sexual activity relate in part to the pathophysiology of the cardiovascular response to sexual activity. This review addresses this subject and reviews studies that directly address the cardiovascular risk associated with sexual activity.

Female sexual behavior: fluctuations during the menstrual cycle.

This longitudinal prospective study was designed to examine the influence of menstrual cycle phase on female sexuality. Sixty-nine normally cycling women monitored their sexual behavior including both heterosexual and autosexual activities and their basal body temperature daily over two or three consecutive menstrual cycles. Temperature charts were used to ascertain five cycle phases (menstrual, postmenstrual, ovulatory, luteal and premenstrual) and data were analyzed using analyses of variance with repeated measures. The results supported a significant cyclic fluctuation in sexual behavior with both female-initiated and male-initiated sexual activities peaking in the ovulatory phase. Moreover, the findings indicated that women experienced increased sexual arousal and sexual pleasure as they progressed from the menses to the premenstruum. These data suggest that human sexual behavior may be influenced by hormonal fluctuations and cognitive factors associated with the menstrual cycle.

Physiological changes during copulation in male and female stumptail macaques (Macaca arctoides).

Radiotelemetric recordings were made of uterine contractions in female stumptail macaques, and of heart and respiratory rate in stumptail monkeys of both sexes, before, during and after copulation. These data were fed into a multichannel recorder, along with a spoken record of behavioral changes. Males' heart and respiratory rates were raised during penile thrusting, reached a peak and then fell sharply after ejaculation. Uterine movements were similar during successive copulations. After uterine movements associated with penile thrusting prior to ejaculation a rise in contraction force occurred which lasted about 15 seconds. It is in this period, if ever, that a climax face was displayed by the female. The female's look-back and reach-back behaviors were not linked to either the pattern of uterine contractions or the occurrence of the climax face.
