Spatial abilities are not related to testosterone levels and variation in the androgen receptor in healthy young men.

Androgens modulate brain functions such as cognition, emotions and ability. Several studies have shown a correlation between testosterone levels and mental rotation. The aim of the present study was to confirm the influence of salivary testosterone levels, 2D/4D ratio (such as a putative marker of prenatal testosterone), and sensitivity of androgen receptor on the mental rotation in healthy young men.

Genetic polymorphisms related to testosterone metabolism in intellectually gifted boys.

Prepubertal testosterone levels are lower in intellectually gifted boys. The aim of this pilot study was to analyze potential genetic factors related to testosterone metabolism in control and gifted boys. Intellectually gifted (IQ>130; n = 95) and control (n = 67) boys were genotyped.

Polymorphisms of candidate genes in Slovak autistic patients.

Autism is one of the most genetically influenced neuropsychiatric disorders. However, its detailed genetic basis is far from being clear. Genome-wide association studies have revealed a number of candidate genes, mostly related to synaptogenesis and various neuroendocrine pathways.
