Introduction Few studies have looked at prevalence estimates for female sexual dysfunctions in combination with personal distress, although existing diagnostic criteria for sexual disorders include both aspects. Further, the variation in female sexual function has been shown to be largely explained by unique nongenetic factors. Such factors may include partner sexual function and perception of sexual compatibility with a partner, factors which may also be associated with sexual distress. Aim We investigated the association between female sexual dysfunction and distress as well as their association with partner compatibility. Methods In order to assess sexual function and distress, the Female Sexual Function Index and seven items from the Female Sexual Distress Scale were used in a population-based sample of 5,463 women, aged 18–49 years. The women were, based on cutoff points, classified as either having neither dysfunction nor distress, one of them, or both, separately for each dysfunction. Further, the associations between partner compatibility, distress, and sexual dysfunctions were analyzed. Sexual compatibility with partner was investigated by using several items exploring, for example, amount of foreplay, interest in sex, and communication about sexual matters. Main Outcome Measures Associations between partner compatibility and female sexual function and sexual distress. Results The proportion of women reporting both sexual dysfunction and distress ranged from 7% to 23%, depending on the dysfunction. Desire disorders followed by orgasmic disorders were most common. All compatibility variables were significantly associated with distress and with most of the sexual dysfunctions. The main complaints of the women were “too little foreplay” (42%) and “partner is more interested” (35%). The women feeling distress or having a sexual dysfunction reported more incompatibility with partner compared with functional women. Conclusions The findings highlight the importance of addressing partner compatibility for successful treatment and counseling of female sexual dysfunctions.

Introduction A number of different theoretical approaches to understanding the etiology of ejaculatory dysfunction have been proposed, but no behavior genetic study has yet, to our knowledge, been conducted to explore the genetic and environmental influences on ejaculatory dysfunction. Aim The aim of the present study was to explore the genetic and environmental effects on premature (PE) and delayed (DE) ejaculation in a population-based sample. Methods The genetic and environmental influences on PE and DE were investigated in a population-based sample of 1,196 Finnish male twins, age 33–43 years, with 91 identical and 110 complete twin pairs. Several different aspects of ejaculatory function were measured by a self-report questionnaire (e.g., latency time, subjective experience of ejaculatory control). Factor analyses distinguished two subcomponents of ejaculatory function, and subsequently, composite variables measuring PE and DE were created. Structural equation modeling was performed on the composite variables. Main Outcome Measures Measurement of genetic and environmental effects on PE and DE. Results The results suggested moderate genetic influence (28%) on PE, but not on DE (0%). There was a moderate familial effect on DE with shared environmental effects accounting for 24% of the variance. However, omission of the shared environmental component did not directly result in a significantly decreased model fit for DE, and omission of the additive genetic component did not directly result in a significantly decreased fit for the PE model. Conclusions The findings from the present study provide useful information regarding the etiology and understanding of ejaculatory dysfunction.

The factor structure and reliability of the Female Sexual Function Index (FSFI) was evaluated in a Finnish population based sample of 2,081 women, age 33-43 years. In addition, associations between female sexual function and age, psychological distress, alcohol use, hormone based contraceptives, child sexual abuse (CSA), and adult sexual abuse were examined. The results supported a six factor solution for the FSFI with high internal consistencies, in line with earlier research in clinical populations. Psychological distress was positively associated with every dimension of the FSFI except desire problems. Age was associated with fewer pain problems. Alcohol use was associated with every dimension of the FSFI, but the direction of the association depended on if it was drinking in general or in connection to intercourse. More drinking in general was related to fewer sexual function problems while drinking in connection to intercourse was related to more sexual function problems. No significant correlation was found between adult sexual abuse and sexual function but between CSA and lubrication, satisfaction, and pain problems. Usage of oral contraceptive pill was not significantly associated with sexual function. The use of hormone based intrauterine systems was significantly associated with less pain and more desire, arousal, and satisfaction. In conclusion, the study supports use of the FSFI for assessing sexual function not only in clinical samples but also in population based samples. The associations found between sexual function and other important variables showed the complexity of sexual function.

OBJECTIVE. Body image and perceived attractiveness were examined, and the impact of age, gender, and body mass index (BMI) was analyzed and discussed from an evolutionary and a sociocultural perspective. METHOD. The population-based sample consisted of 11,468 Finnish men and women aged 18 to 49 years. RESULTS. Both age-related decrease and increase in body satisfaction was detected as well as interactions between age and gender. Some effects were nonlinear. Women were generally less satisfied with their bodies than men. BMI had a stronger influence on women's body image than men's. DISCUSSION. It was proposed that it is insufficient to merely study how age affects general body image because adults might become more satisfied with some aspects of their bodies as a function of age and less satisfied with other aspects. Body satisfaction might also fluctuate during different phases of the adult life, and the patterns possibly differ between men and women.
