The Fast Size Extender, though not extensively tested, has received some validation from mainstream medical sources. But that makes it a true rarity among the nonprescription methods of male enhancement. Most are a waste of money, and some are downright dangerous, doctors say. Sometimes men with erection problems or a diminished libido have low levels of testosterone, Boyle says. Testosterone deficiencies can also affect mood and energy levels. Boyle tests for testosterone levels and prescribes it as a topical gel, though she warns it is only safe when prescribed and monitored by a physician. Nonprescription testosterone, such as the kind used by some bodybuilders, is dangerous, she warns.Instead of furtively turning to untested methods, men with persistent concerns should consider opening up about them with their doctors. That's because performance problems sometimes act as an early warning signal for serious health problems. Your doctor might be able to prescribe something that can really help, or least provide a valuable dose of perspective about what constitutes "normal" sexual performance.
