This one should be a no-brainer, but anabolic steroids are really bad for erectile functioning. Steroid use can lead to infertility, reduced sperm count, and they can really mess up a person's natural testosterone levels. Over time, the steroids interrupt the body's normal hormonal axis, resulting in low testosterone, which can cause erectile dysfunction. For most men, it takes three to 12 months to recover their sperm count after getting off steroids but the damage done depends on how much of the drug was taken and for how long.
