Infertility is the inability to get pregnant through frequent, unprotected intercourse. Infertility can be an issue with the male or the female partner, or sometimes both. When steps in the reproduction process do not happen as they should, or timing is off-- a pregnancy will not happen. Many factors can affect your fertility, a few are: Cervical/Uterine problems, Fallopian Tube damage, Ovulation disorder, age, smoking, weight, and even STDs. While not 100%, there are many options for treating infertility issues.
