Abstract
History:
Infertility is defined clinically in women and men who cannot achieve
pregnancy after 1 year of having intercourse without using birth control,
and in women who have two or more failed pregnancies. Studies suggest
that after 1 year of having unprotected sex, 15% of couples are unable to
conceive, and after 2 years, 10% of couples still have not had a successful
pregnancy [1,2].In couples younger than age 30 who are generally
healthy, 20% to 37% are able to conceive in the first 3 months [3].Many
different medical conditions and other factors can contribute to fertility
problems, and an individual case may have a single cause, several causes,
or—in some cases—no identifiable cause. Overall, one-third of infertility
cases are caused by male reproductive issues, one-third by female
reproductive issues, and one-third by both male and female reproductive
issues or by unknown factors[4].To conceive a child, a man's sperm must
combine with a woman's egg. The testicles make and store sperm, which
are ejaculated by the penis to deliver sperm to the female reproductive
tract during sexual intercourse. The most common issues that lead to
infertility in men are problems that affect how the testicles work. Other
problems are hormone imbalances or blockages in the male reproductive
organs. In about 50% of cases, the cause of male infertility cannot be
determined
