Does age affect sperm quality?

Yes, while men can remain fertile well into later life, sperm quality naturally declines with age. From around the age of 40, there can be gradual changes in sperm count, motility (movement) and morphology (shape). DNA fragmentation within sperm cells can also increase over time, which may make conception take longer and, in some cases, slightly raise the risk of pregnancy complications. If you’re planning to have children later in life, your consultant at Welbeck can arrange a comprehensive semen analysis and provide clear, evidence-based advice on optimising your reproductive health.
