Body image and sexual interests in adolescents and young adults with Prader-Willi syndrome.

BACKGROUND

Hypogonadism is a major feature of Prader-Willi syndrome (PWS), but clinical manifestations are variable. Sexual interests and behavior in this population have not been previously described.

OBJECTIVES

We studied PWS adolescents and young adults to assess 1) satisfaction with physical and sexual development, 2) frequency of romantic and sexual experiences, 3) aspirations and expectations regarding marriage, 4) possible relationships between sexual interests and hormone levels, and 5) the desire for hormonal replacement therapy.

METHODS

The study population consisted of 27 individuals (13 males) ages 17-32 (mean 23.5) years with genetically confirmed PWS. Mean intelligence quotient (IQ) was 75 (range 50-100). We conducted structured interviews using questionnaires specifically designed for this study.

RESULTS

There was a significant negative correlation between IQ and body image in both males and females. IQ showed a positive correlation with interest in dating and romantic activities. Approximately half of PWS males and females reported having been on a date and kissing romantically. All males and 64% of the females wished to be married. Seventy-seven per cent of PWS males wanted hormonal treatment to increase phallic size. We found no correlation between hormone levels and sexual interests. Only 43% of PWS females wanted hormonal medication to achieve regular menstruation.

CONCLUSION

Despite documented hypogonadism, PWS young adults are interested in sexual and romantic issues. The range of sexual activities and expectations is variable. Understanding specific sexual characteristics of each individual is important in order to offer proper anticipatory sexual guidance counseling and for appropriate recommendations for hormone replacement.
