Tobacco's Silent Threat: How It Devastates Male Fertility and Sperm Health

• Tobacco, in all forms (smoked, chewed, passive), directly damages sperm health, often without immediate symptoms, impacting men trying to conceive.
• It reduces sperm count, impairs motility, and increases abnormal sperm shapes, crucial factors for natural conception.
• Toxins like nicotine, cadmium, and hydrocarbons cause oxidative stress and DNA fragmentation in sperm, affecting embryo development.
• Tobacco use disrupts hormones, lowering testosterone and impairing cells vital for spermatogenesis, further reducing sperm production.
• Quitting tobacco can significantly improve sperm quality within 3-6 months, as sperm regeneration takes about 74 days, making damage largely reversible.

Why It Matters: Tobacco severely harms male fertility through DNA damage and hormonal disruption, but quitting can reverse much of the impact.
