(AP) - Zinc and folic acid have been touted as helping male fertility, but a rigorous government-led study says they don’t.

Both are important for sperm production and are found in many foods.

Previous studies on whether over-the-counter supplements might boost sperm health had conflicting results.

The new study involved almost 2,400 U.S. men. Half took daily supplement pills for six months, the others got dummy pills.

There was no difference in sperm quality or live births.

Researchers said they were disappointed by the results published Tuesday.

Supplements cost about $60 monthly versus thousands of dollars for some invasive fertility treatments.
