An abnormal semen analysis, such as a low sperm count, always needs a second test 1-2 months later for confirmation. Based on how low the count is, and/or sperm quality tests like motility and morphology (the % of normal-shaped sperm) are, we may do hormonal or genetic blood work. In some guys taking tablets or rarely shots can increase count. Men who are overweight may get better sperm numbers and quality by losing weight, and men should cut down heavy alcohol use and quit using tobacco, avoid illegal drugs and anabolic steroids, and review any prescription drugs with their MD.
