Metformin improves semen characteristics of oligo-terato-asthenozoospermic men with metabolic syndrome

Fertil Steril. 2011 May;95(6):2150-2. doi: 10.1016/j.fertnstert.2010.12.009. Epub 2010 Dec 30.

Abstract

To examine the appropriate treatment of oligo-terato-asthenozoospermic patients with metabolic syndrome, 45 patients were treated with metformin for 6 months. The use of metformin was associated with a statistically significant reduction in insulin resistance and sex hormone-binding globulin levels, a statistically significant increase in serum androgen levels, and a consequent improvement in semen characteristics.
