Low Sperm Count After 40: Is Age-Related Decline Something You Can Fix?

Men continue to produce sperm throughout adult life, but sperm health can change with age. After 40, some men may have changes in sperm count, movement or quality.

Age is not always the only reason. A low sperm count may also be linked to a medical condition, lifestyle factor or medicine. Proper testing helps identify what may be affecting it.

What Does Low Sperm Count Mean?

Low sperm count means that the semen contains fewer sperm than expected. This can make natural conception more difficult, but it does not make pregnancy impossible.

Sperm movement and shape also matter. The fertility health of the female partner is equally important when planning treatment.

What Can Cause It After 40?

Possible reasons include:

• Age related reduction in testosterone production
• Reducing muscle mass which adversely affects metabolic health
• Varicocele
• Hormone problems
• Diabetes, obesity or other health conditions
• Past infection, surgery or injury
• Certain medicines or cancer treatment
• Smoking, heavy alcohol use or anabolic steroids
• Genetic conditions

Sometimes, the exact cause is not found. This does not mean that treatment options are unavailable.

Can Low Sperm Count Be Cured?

There is no single cure for every case. Improvement depends on the cause. Treating an infection, hormone problem or varicocele may help selected men. Stopping tobacco and anabolic steroids, reducing heavy alcohol use and managing long-term health conditions may also support sperm health.

Do not start testosterone or fertility supplements without medical advice. Testosterone taken from outside the body can reduce sperm production, while supplements may not address the actual cause.

How Is It Checked?

The first test is usually a semen analysis. Because results can change, the doctor may recommend another sample. Hormone tests, an examination, ultrasound or genetic testing may be advised depending on the findings.

The female partner should also be evaluated so that the couple does not lose time following a treatment that may not suit their situation.

What Treatment May Be Suggested?

Treatment may focus on the cause or help the sperm and egg meet. Options can include timed intercourse, IUI, IVF or IVF with ICSI. The right approach depends on the sperm report and the complete fertility evaluation of both partners.

At Bavishi Fertility Institute, male and female fertility are assessed together before treatment is planned.
