Androgens have been linked to visuospatial ability. We examined the relationship between serum free testosterone (T) levels and spatial visualization ability in a population-based sample of 450 healthy men between the ages of 35 and 80 years. They were tested on block design and Mini Mental State of Examination (MMSE) draw-a-figure, as well as tasks assessing episodic memory, semantic memory, procedural memory, and verbal fluency. Blood was analyzed for free T and estradiol. Participants were grouped into high or low free T based on age-specific median values. Participants with low free T performed at a superior level on both the block design task and draw-a-figure task as compared to participants with high free T. The results are discussed within the scant body of research on androgens and cognition in men.
