True fertility in men is best confirmed by a semen analysis (sperm count 15 million/ml, motility 40%, normal morphology 4% according to WHO criteria), but several everyday signs can suggest good reproductive health: Consistent healthy libido and erectile function Normal morning erections and spontaneous erections Stable energy levels and mood (reflecting balanced testosterone) Normal ejaculation volume and no pain during ejaculation Overall good physical health (healthy weight, no chronic fatigue, no obvious hormonal symptoms like excess body fat around the midsection or reduced muscle mass) However, many men with completely normal appearance and libido can still have suboptimal sperm parameters (low motility, DNA fragmentation, etc.) that only show up on testing
