Does supplementation with zinc improve sperm health or fertility?

    Last Updated: October 13, 2024

    Animal studies show that zinc deficiency is associated with low testosterone, abnormal testicular function, and infertility.[1][2][3][4] Some human studies have reported similar observations,[4][5][6][7] but because of the lack of clinical trials, conclusions about the effect of zinc supplementation on sperm health or fertility aren’t currently possible.[8][9][7][10]
