AbstractSexual dysfunction is one of the most bothersome adverse drug effects seen in men and women taking antipsychotic medications and negatively impacts medication adherence. Antipsychotic medications are associated with hyperprolactinemia, which is known to contribute to sexual and hormonal side effects in men. However, testosterone also plays a key factor in male sexual function and may be affected by abnormal prolactin levels through gonadotropin-releasing hormone inhibition. This study was a pilot study undertaken to assess the prevalence of elevations in prolactin levels, related reductions in testosterone levels, associated symptoms of sexual dysfunction and breast abnormalities in male participants, and related distress to these symptoms in men taking prolactin-elevating antipsychotic medications. The study was conducted as a cross-sectional study. Our results showed a notably high prevalence of sexual side effects in this population, with gynecomastia occurring in 50% and penile-related symptoms in 73%. Additionally, we found elevated prolactin levels in 68% and low testosterone levels in 55% of our participants. This study was limited in its power due to a small sample size of 22 men and the lack of a control group. Still, even in our relatively small sample, we see a trend of hyperprolactinemia being associated with low testosterone and a significant correlation of low testosterone levels with penile-related symptoms. This suggests that testosterone plays a major role in the sexual side effects reported by men taking antipsychotics, although larger studies are needed to further categorize this relationship.
