Selenium and NAC increase sperm count

Selenium and N-acetyl-cysteine increased and normalized sperm, in a recent study. 

Some infertile men have low sperm counts, poor sperm quality and impaired sperm movement. In a fertility study, researchers wanted to see if selenium and/or N-acetyl-cysteine (NAC) could improve sperm health. About 500 infertile men took 200 mcg of selenium per day, 600 mg of NAC per day, these two nutrients combined or a placebo.

After 26 weeks, men who had taken selenium and N-acetyl-cysteine together had more sperm with normal structure and form, more balanced levels of a group of hormones that regulate and control the number of sperm, more concentrated sperm counts and better sperm movement. Good sperm movement, or motility, refers to the ability of sperm to move toward the egg. Doctors concluded, “These results indicate that supplemental selenium and N-acetyl-cysteine improve semen quality,” adding, “we advocate their use for male infertility treatment.”
