I always tell my patients that the risk of sexual dysfunction or loss of libido was between 2-4% but this article suggests that these side effects were not seen in their study of over 600 men from all age groups. This suggests a strong psychological impact that could be the cause of the sexual complaints reporting “there is evidence of a nocebo effect (an adverse side-effect that is not a direct result of the specific pharmacological action of the drug)“. The link below is a copy of the article which should be read by our audience. The main thrust of the article, however, was that “recent research … suggests that men with alopecia may be inherently more susceptible to sexual dysfunction regardless of treatment and that sexual dysfunction is not uncommon in the general population regardless of alopecia status.” I personally know the first author, Dr. Robert Haber and he is an honest and diligent clinician who I trust.
