Tip 2: Stick to Zinc and Selenium Supplementation
Zinc and selenium together can improve sperm quality and vitality, shorten sperm liquefaction time, promote spermatogenesis, and enhance immunity. Only when sperm vitality is improved can male sexual performance be maintained. It is medically recommended for men over 50 to take Yuzhiyuan pills for 2-3 months, which greatly helps promote sperm production, improve sperm activity, and maintain male sexual function.
