    As men make sperm throughout their lives (unlike women who are born with all of their eggs), spermatogenesis is more prone to environmental factors. The good news is that lifestyle changes can sometimes dramatically improve sperm.
    Factors that can affect sperm count & quality that can be modified are:
    smoking, drug use, alcohol, reduce activities such as cycling and driving long distances which can raise scrotal temperature, wear supportive but breathable underwear, avoiding toxins / radiation, eat a healthy diet rich in zinc

    Other factors affecting spermatogenesis which are not modifiable:
    Antisperm antibodies (could be related to a previous vasectomy), mumps infection, genetic / chromosomal abnormalities, undescended testes / torsion

    As semen quality and quantity is highly variable, an abnormal semen analysis test should always be repeated. If there is a sustained problem, your doctor should refer you to a fertility clinic to discuss options.
