Taking medication for hair loss might cause sexual problems.
research Comments concerning the real risk of sexual adverse events secondary to the use of 5-ARIs
The document concludes that the risk of sexual side effects from 5-alpha-reductase inhibitors is low and often temporary, but more research is needed on potential permanent effects.
research Women Also Use 5α-Reductase Inhibitors—Reply
Women also use 5α-reductase inhibitors, and their effects differ from men.
research Pharmacokinetic parameters and mechanisms of inhibition of rat type 1 and 2 steroid 5α-reductases: determinants for different in vivo activities of GI198745 and finasteride in the rat 3 3Abbreviations: r5AR1, rat 5α-reductase 1; r5AR2, rat 5α-reductase 2; and DHT, dihydrotestosterone.
