If you are concerned about your fertility, the first thing for you to know is that you are not alone. According to World Health Organisation (WHO), about 15% of couples of childbearing age seek medical help for infertility, usually after about two years of failing to conceive.

The problem can stem from both female and male issues. Generally speaking, source of infertility is

• Exclusively with female in about 30 - 40% of cases.
• Exclusively with male in about 10 - 30% of cases.
• A combination of both partners having detectable abnormalities in 15 - 30% of cases.

After medical examinations, causes of infertility remain unexplained in only 5-10% of couples. WHO believes that there are around 60-80 million infertile couples in world.

Now, whilst this may come as no real consolation (but may help put situation in some context) - becoming pregnant is not that easy, even for people who do not have fertility problems!

It's a little known fact that humans are one of least fertile creatures on earth. There is only a fairly short time within menstrual cycle when conception is possible, making chances of conception only 25% each month. It is estimated that 10% of normally fertile couples fail to conceive within their first year of attempt and 5% after two years.

Between 2 and 10% of couples worldwide are unable to conceive a child and a further 10 - 25% experience secondary infertility, in other words, they are unable to conceive a second or subsequent child.
