How Does One Even Measure Libido or Propecia’s Effect On It?

Hi Dr Rassman,

I would like to ask a question that has been on my mind for years, but haven’t seen an answer to this question. I’m 30 year old male.

How would I ever know if propecia is having an effect on my libido, sex drive etc? After all, these effects are not practically measurable. For instance, my libido is constantly changing from month to month, and even a day to day basis. How would I ever know it’s having an effect? I don’t currently take propecia, but am considering it. This has been my biggest factor in deciding to take the drug. Appreciate any recommendations that you can make to help measure these effects.

Thanks for a great blog.

One does not measure libido, as this is a subjective call for everyone. You are right — our libidos do vary with mood, age, time of the day, stress in our lives, relationships, etc…

The decision about taking a drug like Propecia should relate to a Master Plan for your hair loss problem.
