This study found that 94% of healthy men reported low libido and 92% reported erectile dysfunction as persistent sexual side effects after using finasteride for male pattern hair loss, with these effects lasting on average 40 months post-discontinuation.

This review discusses persistent adverse effects of 5α‐reductase inhibitors, like diminished libido and erectile dysfunction, in some patients and highlights the need for patient discussions before therapy, especially for androgenetic alopecia.

In this study, oral finasteride improved the quality of life for male patients with androgenetic alopecia, but it did not significantly reduce anxiety or correlate with reported anxiety levels.

This study found that daily oral finasteride may increase hair count and improve hair appearance assessments in men with androgenetic alopecia, but it also appears to raise the risk of sexual dysfunction.

In this study, 19 patients treated with finasteride for androgenetic alopecia developed moderate to severe depression, which resolved after stopping the medication, suggesting an association between finasteride and mood disturbances.

This review discusses the psychological and social impacts of androgenetic alopecia and suggests that medical treatments can have some positive psychological effects, highlighting the condition's moderate stress and impact on body image.

In male pattern hair loss, this study found that finasteride 1 mg daily significantly slowed hair loss and increased hair growth over two years compared to placebo.

Too much androgen can cause hair loss; finasteride may help.

In this study, 5 mg of finasteride per day significantly improved urinary symptoms and reduced prostate volume in men with benign prostatic hyperplasia, but increased the risk of sexual dysfunction.

In this study, men with androgenic alopecia taking minoxidil gel generally showed no evidence of psychological malfunction, but those over 35 experienced greater psychological improvement when they had cosmetic success with the treatment.
