Although the prevailing opinion is that emotional processes are influenced by sex hormones, the literature is still inconclusive. The aim of the current study was to examine the effects of gonadal suppression on brain activity during affective picture processing. Twenty-one female-to-male (FtM) transsexuals and 19 control women were recruited and underwent(More)
Functional magnetic resonance imaging (fMRI) analysis is usually carried out with standard software packages (e.g., FSL and SPM) implementing the General Linear Model (GLM) computation. Yet, the validity of an analysis may still largely depend on the parameterization of those tools, which has, however, received little attention from researchers. In this(More)
OBJECTIVE To investigate the effect of hormonal androgenic treatment on antimüllerian hormone (AMH) serum levels in female-to-male (FtM) transsexuals. Polycystic ovary syndrome (PCOS) is associated with elevated AMH levels. Some hypothesize that the high AMH level is a consequence of androgen-induced excessive development of small antral follicles. However,(More)
INTRODUCTION In the literature, verbal fluency (VF) is generally described as a female-favoring task. Although it is conceivable that this sex difference only evolves during adolescence or adulthood under influence of sex steroids, this has never been investigated in young adolescents. AIM First, to assess sex differences in VF performance and regional(More)
OBJECTIVE Little is known about the function of the ovarian neuronal network in humans. In many species, copulation influences endocrinology through this network. As a first step, the possible influence of ovarian mechanical manipulation on pituitary and ovarian hormones was evaluated in polycystic ovarian syndrome (PCOS) and regularly cycling women. (More)
OBJECTIVE To study effects of overexposure to androgens and subsequent antiandrogenic treatment on brain activity during working memory processes in women with polycystic ovary syndrome (PCOS). DESIGN In this longitudinal study, working memory function was evaluated with the use of functional magnetic resonance imaging (MRI) in women with PCOS before and(More)
