Stress can significantly impact male fertility by disrupting hormone levels, specifically increasing cortisol, which can lower testosterone production and sperm quality. Chronic stress may lead to erectile dysfunction and decreased libido. Stress can also affect semen quality, altering sperm motility and morphology. Diagnostic tests, such as semen analysis and hormone tests, help assess fertility health, identifying issues influenced by stress that may require targeted treatments like stress management techniques or medical interventions.
