The most common problem is a declining sex drive. It takes a lot of stimulation to bring an erection, and when Willy finally does perk up he's no match for the woodies of yesteryear, nor is the ejaculation as strong. The amount of semen is also much less, and if you care to measure, you will find that the testicles are a bit smaller than before.
最普遍的是性慾減退，要刺激很久才能勃起，勃起時不再剛硬昂然，射精的強度減弱，射精量明顯減少，仔細觀察，還會發現兩顆「小蛋蛋」已略有萎縮呢。
