Improvement in fertility in men with a dietary supplement

This randomized, double-blinded and placebo-controlled trial examined the effects of a dietary supplement on fertility in men with idiopathic subfertility. 83 men with either oligo-, astheno or terato-zoospermia have been enrolled in this study. They were supplemented with a placebo or a dietary supplement containing L-carnitine/acetyl-L-carnitine, L-arginine, glutathione, co-enzyme-Q10, zinc, vitamin B9, vitamin B12 and selenium.

After 6 months of supplementation, more men from the supplemented group had a normal spermiogram in comparison to the placebo group (29/42, 69.0% vs. 9/41, 22.0%, p < 0.001). Moreover, the rate of spontaneous pregnancy was greater with the dietary supplement than with placebo (10/42, 23.8% vs. 2/41, 4.9%,p = 0.017).

Therefore, the dietary supplement tested in this study was effective for normalizing the spermiogram of men with idiopathic subfertility. This improvement was associated with an increased pregnancy rate.
