Infertility in Men; Sperm Motility

Infertility is the inability of a man to father a child in a fertile woman. It is diagnosed after one year of regular, unprotected sex. It may be caused by:

  • Low sperm count
  • Low sperm motility
  • Ejaculation problems

For some men, the cause may be unknown. Treatment may include medicine or surgery to repair any problems. Lifestyle changes may also help.

Natural Therapies

Natural therapies may affect sperm motility, count, or concentration in the semen. These therapies do not appear to affect problems with testosterone levels or improve pregnancy rates.

Antioxidants may be part of a treatment plan. Keep in mind that eating a healthy diet with plenty of fruits and vegetables may be more useful than taking supplements.

Herbs and Supplements to Be Used With Caution

Talk to your doctor about all herbs or supplements you are taking. Some may interact with your treatment plan or health conditions.

In general, antioxidant vitamins, and minerals are safe when taken as directed. Do not exceed the recommended daily upper intake levels (ULs).

Excessive zinc is toxic and may cause copper deficiency, impaired immunity, anemia, or other serious problems.
