Finasteride-associated male infertility

TLDR Finasteride may cause male infertility, stopping it can help.
This document discusses a case study of a male patient who experienced infertility while taking finasteride for androgenic alopecia. After discontinuing the medication, the patient's semen volume and sperm concentration improved. The authors suggest that finasteride at a dose of 1 mg may have an adverse effect on male fertility in cases of pre-existing subfertility, and cessation of the drug could be taken into consideration in infertile male patients with impaired semen parameters who are taking finasteride at the 1-mg dose.
