The Fertility Test Most Men Are Never Offered | Dr Michael Eisenberg and Dr Natalie Crawford

Male fertility is a critical, often overlooked component of reproductive health that serves as a vital indicator of a man’s current and future physiological well-being. With male factors contributing to 50% of infertility cases, routine semen analysis is essential for identifying potential issues before they become chronic. Sperm health is highly malleable, with lifestyle interventions—such as prioritizing sleep, optimizing diet, and avoiding toxins like cannabis and exogenous testosterone—significantly improving parameters within a 90-day cycle. Because sperm quality correlates with metabolic health and longevity, proactive testing provides actionable data for long-term health management. Couples should move beyond the traditional "wait-and-see" approach, as early diagnostic testing empowers partners to address underlying issues, optimize their chances of conception, and mitigate risks associated with advanced paternal age and environmental exposures.
