One in six couples face the problem of infertility, but only every other couple seeks medical attention. Infertility is defined as a situation where a woman has not been able to conceive for a period of one year, even though the couple has not been using contraception. Infertility is rarely conclusive – this can only be said if the woman has no uterus and fallopian tubes, or if the ovaries have stopped working. It is also very rare for men to have no sperm. But at the same time, the longer the infertility lasts, the less likely it is to become pregnant. Both fertility and the success of the fertility treatment are greatly affected by a woman’s age: as a woman ages, her fertility decreases and the effectiveness of the fertility treatment decreases as well.
