We’ve been preaching this for years in our talks and directly with our patients. The body is a delicate balance between pro-oxidants and antioxidants. There is an appropriate time for oxidation and an appropriate time to prevent oxidation. Knowing which to do is something that you should consult with a clinician about. They can run lab tests or perform a physical exam that can help determine which you need.
 
This recent study is more evidence of the damage that can be caused by the vitamins that many companies tout will improve male factor infertility. In this study, the antioxidants essentially created sperm that was not very functional but pretty…looks aren’t everything in the world of sperm either.
 
You could say that the antioxidants gave the sperm premature ejaculation, a process known as sperm decondensation. Because the genetic matierial is released too early, it is ineffective at inducing pregnancy.
