Half of all cases of infertility are due to male factor, and recent news articles and research have put male fertility back in the spotlight.
The good news is that unlike women who are born with all of the eggs they will ever have, men continue to produce sperm. So what a man does now can improve his fertility two to three months from now.
Diet, lifestyle and nutritional supplements — all can affect a man's fertility. These factors can also affect a couple's chances at a successful in vitro fertilization (IVF). A recent Brazilian study of 250 men who were undergoing IVF with intracytoplasmic sperm injection (ICSI)published in the journal Fertility and Sterility found that the chances of a successful IVF increase if men have diet high in fruit and grains, and low in red meat, alcohol and coffee. The men's weight and diet had an effect on sperm concentration and motility (how well sperm swim).
