Q: What are the key functions of testosterone?
A: As the primary male sex hormone, testosterone is responsible for the development and maintenance of the physical attributes that distinguish men from women. Just as men have low levels of estrogen, the main female hormone, women have testosterone but at much lower levels than in men. In both sexes, testosterone plays an important role in sexual desire, without which men are unlikely to have an erection. But it plays no direct role of consequence in the physical mechanics of erectile function.
Q: What are normal testosterone levels?
A: Testosterone levels vary significantly from one man to another, and they do tend to decrease as a man ages. However, normal T-levels range widely from 300 to 1,200 nanograms per deciliter, according to UrologicalCare.com. Interestingly, a man with 300 nanograms per deciliter might enjoy normal erectile function, while a man with much higher T-levels could be diagnosed with ED. In other words, T-levels are not a reliable indicator of a man’s ability to get and keep an erection, which depends to a very large extent on the strength of blood flow to his penis.
Q: What are the symptoms of low testosterone?
A: As previously noted, a drop in sexual desire is often associated with a testosterone deficiency. Other common symptoms include anxiety, depression, difficulty concentrating, elevated cholesterol levels, irritability, and weight gain. If you suspect that you are suffering from low testosterone, consult your doctor who might prescribe hormone replacement therapy to nudge your T-levels back into the normal range if blood tests confirm a deficiency.
If you’re having difficulty getting and keeping an erection, the drugs most likely to help are the oral ED drugs, such as Viagra, which are known collectively as PDE5 inhibitors. If you have a doctor’s prescription for Viagra or another PDE5 inhibitor, you can fill it locally or use it to order the medication online. eDrugstore.com, a longtime online facilitator, sells only FDA approved drugs that are sourced exclusively from licensed U.S. pharmacies.
