Why Is My Sperm Count Low Despite Being Healthy?

Men who look healthy can still have low sperm count due to hidden hormonal, genetic, vascular or lifestyle factors.

Hormones

FSH, LH, testosterone, prolactin and thyroid function influence sperm production. A man may feel healthy but still have a hormonal pattern that reduces sperm count.

Genetics

Some men have genetic or testicular factors that are not visible externally. Severe low count may require specialized evaluation.

Varicocele and infections

Varicocele, past infections, heat exposure, fever and inflammation can reduce sperm production or quality.

Lifestyle and next steps

Smoking, alcohol, obesity, poor sleep, gym steroids and toxins can contribute. Treatment depends on identifying which factors are reversible.
