Clinical and Experimental Dermatology2024
Summary (paraphrased)
This scoping review searched for peer-reviewed studies on isotretinoin and sexual dysfunction using a broad set of terms covering erectile, ejaculatory, libido, arousal, orgasmic, fertility, and menstrual outcomes. It included 55 manuscripts (8 animal, 46 human studies with 2,420 patients): 18 case reports/series, 2 case-control, 4 cross-sectional, 6 longitudinal, 3 pharmacovigilance reports, and 13 cohort studies, mostly at 0.5-1.0 mg/kg/day for 1-6 months. More than half of human studies reported beneficial or neutral effects on sexual function, and 89% were Oxford evidence level 4. The authors conclude the evidence for a link is very weak, argue that heterogeneous definitions of sexual dysfunction make studies hard to compare, and call for standardized definitions and a causality framework.
Why it’s in the corpus
The most comprehensive mapping of the isotretinoin-sexual-dysfunction literature (55 papers); documents exactly why this field is stuck — low-level evidence and inconsistent definitions — and is essential context for any PRSD claim in the corpus.
