Abstract
The associations were examined in women between personality traits and steroid hormones, particularly androgens, as well as polymorphisms in genes regulating androgen concentration and effects. Women, all 42 years of age and premenopausal (n = 270), were recruited randomly. Conventional “masculine” and “feminine” personality traits were examined by questionnaire and set in relation to psychosocial and socioeconomic conditions, behavior in childhood, hormones, risk factors for disease, and polymorphisms in microsatellites in the CYP aromatase and the androgen receptor gene. The proportions of personality traits considered as being dominated by “masculinity” (M) or “femininity” (F) were 44.9%, respectively 15.0%, the rest consisting of a combination of M and F (33.2%) or “undifferentiated” (6.9%). M characteristics were positively associated with education, sporting, self-confidence, and good adaptation to work situation. M scores correlated with reports of “tomboyism” as girls. There was essentially no difference in hormones or disease risk factors between M and F women. The number of (CAG) repeats in the microsatellite of the transactivating domain of the androgen receptor was 19 (2.3; M and SD). M characteristics were more pronounced in the presence of longer repeat stretches (n > 20). No associations were found with F scores. There were no significant associations to the number of tetranucleotide repeats (TTTA) in the fourth introne of the aromatase gene. It was concluded that a majority of women showed M type of personality traits, associated with normal hormones, somatic health, and a long microsatellite in the transactivating domain of the AR gene.
