Case 1: 27-year-old male without any clinical or surgical antecedent of relevance. Between January and July of 2014, he was under treatment with finasteride 1mg/day for androgenetic alopecia, without any adverse effects. After a non-protected sexual relationship and the necessity to initiate prophylactic antiretroviral treatment, he suspended the intake of finasteride because of digestive intolerance, and resuming its use in September of 2014. After twenty days, he began showing signs of low libido and less morning erections, as well as penile shrinking, therefore decided to discontinue the drug 10 days later.
