Characteristics of men who report persistent sexual symptoms after finasteride use for hair loss.

Symptomatic finasteride users had “significantly lower International Index of Erectile Function composite score” and “significantly lower scores for each of its domains of erectile function, sexual desire, orgasmic function, intercourse satisfaction, and overall satisfaction”… There exists “a significant positive correlation between a subset of Beck Depression Inventory scores related to negative attitude and blood oxygen level-dependent activity in the right nucleus accumbens, left pregenual anterior cingulate cortex, right insula, right lateral orbitofrontal cortex, and left posterior cingulate, as well as a negative correlation between BDI subscores and BOLD activity in the right parahippocampal/ fusiform gyrus. This neural circuitry overlaps with functional abnormalities that have been identified in major depression.”
