Rogaine and erectile dysfunction
To date, no scientific studies have made a connection between Rogaine and sexual dysfunction. Men who take Rogaine and experience problems with libido, erection, or performance will often find another contributing factor that explains their symptoms.

At this time, there is still no confirmed evidence that Rogaine adversely affects the male libido, although research continues.
