How to Reduce Viscosity in Sperm

When a semen analysis is performed, one factor that is closely examined is viscosity, or the liquidity of the ejaculate. Free-flowing ejaculate lets the sperm travel into the cervical mucus without difficulty; viscous, or thick, ejaculate can slow or even halt the progress of sperm, making it difficult to fertilize the egg. Viscosity can be reduced by using simple lifestyle changes or with medical treatment.

Take a multivitamin that includes zinc. Balancing your nutrients can help to boost semen production.

Avoid diuretics, such as caffeine, nicotine and alcohol. These substances cause dehydration, and when consumed in large quantities can interrupt hydration necessary for semen production. Make sure you are avoiding these substances and are drinking enough water—6 to 8 glasses per day—for proper hydration.

Use a guaifenesin medication. Guaifenesin, an expectorant, can be found in over-the-counter cold and cough medications. The expectorant loosens and frees mucus, allowing it to flow freely.

Have your doctor perform a prostate exam. An infected prostate can prevent semen from liquefying properly; this can be treated with antibiotic therapy.

Have a doctor wash your semen to separate sperm from the ejaculate. The result of a sperm wash is motile sperm in a non-viscous medium, which can then be used for home insemination or intrauterine insemination performed by a doctor.
