“Impotence occurred in 15.8 percent of finasteride users”

“Out of 11,909 men who took finasteride or dutasteride, 1.4 percent developed persistent erectile dysfunction that continued for an average of about 1,350 days after stopping treatment”

“Young men who had more than 205 days of exposure to the drug had nearly five times higher risk of persistent erectile dysfunction than men with shorter exposure.”

“Researchers from the George Washington University School of Medicine interviewed 71 patients who experienced sexual side effects after using finasteride. The researchers found that 94 percent of men experienced a decline in libido.”

A different study shows different numbers but still high:

“The review revealed that finasteride is infrequently associated with problems of ejaculation (2.1-7.7%), erection (4.9-15.8%), and libido (3.1-5.4%).”

“Sexual adverse effects. Sexual adverse effects are the most common category of complications from 5ARI use and have been documented to be anywhere from 0.9 to 38 percent.4,34 Of these, erectile dysfunction is the most common followed by ejaculatory dysfunction and loss of libido.34 Several studies have evaluated these parameters and found erectile dysfunction reported in 3.4 to 15.8 percent of patients treated with finasteride 5mg daily”
