Anecdotal Reports. The manufacture of rogaine (generic minoxidil) does not report any sexual side effects. A search of the internet reveals many anecdotal reports of sexual side effects from rogaine but no supportive scientific data. Another popular medication used to treat hair loss, Propecia (generic finasteride), is well known to cause erectile dysfunction and loss of libido in a small percentage of patients.
Rogaine (minoxidil) Oral rogaine (minoxidil) (pill) can cause side-effects but not related to sexual functions. Propecia can cause erectile dysfunction & changes in libido but rarely.
Does propecia (finasteride) cause less desire for sex, difficulty in achieving an erection, or a decrease in the amount of semen. I am using minoxidil for alopecia.
Possibly. Propecia (finasteride) is a testosterone antagonist, so it could cause all the symptoms you mention.
