When taking Finasteride for MPB for whatever reason my prolactin sky rockets to 3x greater than top of normal range (confirmed by bloods both on and off finasteride). Being a male i have read that prolactin is the biggest libido and erection killer as far as hormones go - which may well explain why i have such poor libido when on the drug. My ED comes and goes. Is there any objection to combining these drugs ?
