My libido is very low. very tired. trouble maintaining erection. dr tested me for low t, was on low side of normal. looking for possibly getting rx for low t or viagara maybe. oh, im 51 btw.

Repeat T with free T: Hi. Testosterone levels do fluctuate. Repeat a T and have a free testosterone included. If you're found to be low, testosterone therapy may help. Likewise, the Viagra (sildenafil) family of drugs may help if your T is found to be adequate. Always need to consider other factors like how good is the relationship, depression, not making time for carefree sex, etc.
