Supplements have been usually studied in combination with medical infertility treatments. Small studies suggest that males with infertility that take dietary supplements like zinc, vitamin E, or L-carnitine may have improved sperm motility and/or increased success with assisted reproductive technologies.[1] Many other dietary supplements have been studied for infertility with no good evidence of benefit. Some of these supplements include black seed oil, ginger, coenzyme Q10, and vitamin D.[2]
