I have been taking Levoxyl for several years now. I am not taking other medications for the last several years that I have not taken before Levoxyl. I have noticed less sperm produced and lower sexual endurance during sexual intercourse. Although my free testosterone appears in the normal range and my sperm seems to be fertile, I have concerns that Levoxyl may impact my sexual activity and potentially impact my reproduction capabilties in the future.
