When we talk about fertility, much of the focus tends to fall on women and their biological clock. But the truth is, age affects male fertility too. While men do not experience a sudden drop in fertility like women do with menopause, age can still significantly impact sperm quality and overall reproductive health.

As men get older, particularly after the age of 40, there are noticeable changes in sperm count, motility (how well sperm can swim), and morphology (shape of the sperm). These changes can make it more difficult to conceive naturally and may increase the time it takes to achieve a pregnancy. In addition, older paternal age has been linked to a higher risk of miscarriage and certain genetic conditions in offspring.

At London Andrology, we regularly see men of all ages concerned about their fertility. One of the most important messages we can share is that male fertility is not fixed — it can be supported, assessed, and in many cases, improved with the right lifestyle changes and medical interventions.

Factors such as smoking, excessive alcohol, being overweight, stress, and lack of exercise can all affect sperm health — and their impact becomes more pronounced with age. That’s why it’s important for men who are considering starting a family, especially later in life, to take proactive steps toward their reproductive health. This includes having regular check-ups, getting a semen analysis, and addressing any underlying health conditions early on.
