Mt boyfriend is 24 and was recently tested as having low testosterone. He has a level of 341. We have had many problems in our year long relationship, all relating to his lackof sex drive. He has little to no desire for sex. He enjoys being with me, but there has been no sexual contact since his test. His doctor gave him a prescription for androgel and he has been using it for about 2 1/2 weeks. He says he feels no change in libido at this point. He does say he feels healthier and i have noticed a change in his mood. How long does it normally take for a change in libido to occur. I know that everyone is different. The information packet said at 3 months there was an almost certainty there would be an increase. I assume it happens before that. Right now we both love each other and are just waiting to see if the medicine an help us have a relationship. I am in love and feel i have found my soul mate...i just want to know how long I should wait before we both have to admit to ourselves that things with us may never work out due to this issue. So any guidelines as to how soon it should work would be appreciaited. Anyone else out there in these types of drugs your help would be appreciated also. He is taking androgel 5%. Thank you all.
