Infertility is the inability to produce a new organism naturally. Most male infertility is due to low sperm count and sexual problems.
The World Health Organization defines “infertility” as failure of the male or female reproductive system to achieve pregnancy after 12 months or more of unprotected intercourse. It has been found that 40 percent of this infertility occurs in males, 40 percent in females and 20 percent in both sexes.
