Effect of Alpinia officinarum Hance rhizome extract on spermatogram factors in men with idiopathic infertility: A prospective double-blinded randomised clinical trial.

Abstract

Despite scientific advances, many of the treatments in male infertility remained indeterminate. In recent years, the attention to herbal remedies as an effective treatment for male infertility is considerable. We designed this study to determine the effects of Alpinia officinarum on the results of semen analysis in men with idiopathic infertility. In this clinical trial, seventy-six participants with idiopathic infertility were included in the intervention (plant treatment: n=31; placebo: n=29). Participants were randomised to take capsules containing dried extract of A.officinarum rhizome or placebo on a daily (total daily dosage of 300mg) basis for 3months. After 12weeks of intervention, the sperm count and total number of spermatozoa with normal morphology were increased in participants treated with A.officinarum extract compared with the placebo group. The mean sperm count was initially 52×106 ±24×106 /ml which changed to 71×106 ±23×106 /ml, after intervention (p=0.043). Also, the mean percentage of spermatozoa with normal morphology was 14.34%±9.16% before the treatment which significantly increased to 19%±14.89% (p<0.001). Alpinia officinarum, a traditional medicine remedy, can be effective in the improvement of sperm morphology and sperm count in idiopathic infertility without causing adverse effects.
