Acute stress induces a rapid increase of testosterone in a songbird: Implications for plasma testosterone sampling KU Leuven Universiteit Antwerpen
Testosterone (T) and glucocorticoids, such as corticosterone, have both been shown to be important for the way vertebrates in general, and birds specifically, react to their immediate environment. For both corticosterone and T, many sources of variation in plasma levels have been demonstrated. Interestingly, a small number of studies on bird species have indicated that acute stress can have a positive effect on plasma T levels, analogous to what ...
Low Free Testosterone is Associated with Hypogonadal Signs and Symptoms in Men with Normal Total Testosterone KU Leuven
Context: During ageing, total testosterone (TT) declines and SHBG increases, resulting in a greater decrease in calculated free testosterone (cFT). Currently, guidelines suggest using TT to diagnose androgen deficiency and to reserve cFT only for men with borderline TT. Objective: To investigate if either low cFT or low TT is more strongly associated with androgen-related clinical endpoints. Methods: 3334 community-dwelling men, aged 40-79, were ...
No evidence for a causal effect of exogenous testosterone on risky decision-making in women : an experiment and meta-analysis Universiteit Gent
While strong claims have been made that testosterone increases risk-taking, the existing literature is inconclusive. Thus, our experiment aimed at addressing some shortcomings of previous work. First, risk-taking was assessed using the Columbia Card Task, which allows to decompose overt risk-taking into three task factors-gain amount, loss amount, and the probability of losing-in both a dynamic, more affective ("hot") and a static, more ...
Effects of testosterone therapy on constructs related to aggression in transgender men : a systematic review Universiteit Gent
Background: Transgender men are assigned female sex at birth, but identify as men. The anabolic and androgenic sex hormone testosterone has been positively associated with aggression. Therefore, transgender men are warned of increasing aggression when initiating testosterone therapy. Aim: To explore the literature regarding the effects of testosterone therapy on aggression-related constructs in transgender men. Methods: Following ...

Testosterone and fathers' parenting unraveled : links with the quantity and quality of father-child interactions Universiteit Gent
Objective Individual differences in quality of father involvement in caregiving might in part be explained by fathers' testosterone (T) levels. We examined the links between fathers' (n = 32) salivary T levels, amount of time spent with their child (12-30 months of age), type of father-child interaction, and fathers' sensitivity. Methods During two home visits, video observations of father-child interactions were conducted to measure fathers' ...
