These have different goals. Semenax is our top pick among semen-volume supplements: its one small, company-funded trial found a modest volume increase versus placebo, but no change in sperm count, motility or shape. Fertility Factor 5 is aimed at male fertility, with LJ100 Tongkat Ali, Panax ginseng, zinc and selenium, and hasn’t been tested as a product. Men trying to conceive should start with a semen analysis and a doctor.
