Why is this?

Well, it is because a young woman is fertile only a few days in a month. When you get older or have any health problems ovulation (egg release) becomes rarer. It may happen once in 2-3 month or even more rarely.

So, when a woman is fertile for only 1-2 days in 2-3-4 months it gets very complicated to pinpoint their fertile days. And often this is only the reason why a pregnancy does not occur.

The best way to identify your ovulation day is by using a natural method. Identifying ovulation time with special devises can lead to mistakes, especially devises that check the level of hormones in the urine.

The level of hormones in urine increases later then it happens in the blood. So, when you see your ovulation time on a urine analysis devise it could be too late, especially in older women as the egg has already been released.

Secondly, when you identify you ovulation time it is important to deliver the highest amount of sperm possible. To achieve this, your partner should abstain from any sexual activity for at least 3 days before your ovulation time occurs to build up the amount of sperm. No ejaculation at all for 3 days.

Thirdly, it is important to have sexual intercourse not just randomly around ovulation time but on the exact day when a fresh egg has just been released.

The last research shows that an old egg (which has been released 2-3 days ago) is unlikely to end up in a healthy pregnancy. And even when an old egg meets sperm and fertilization does occur the fetus will not survive long and pregnancy will finish with an early stage miscarriage. A woman in this case may not even realize she is having a miscarriage. It normally looks like an overdue period that happens to be heavier than normal.

Old sperm that has been released for more then 24 hours can also be potentially defective. This can give the same result like the old egg, ending up with an early stages miscarriage.

That means that having intercourse before the exact ovulation time is not very beneficial to falling pregnant and achieving a healthy pregnancy.

To sum up, many older women or women with different medical problems may have only 1-2 days in a few or many months when they can fall pregnant. They often miss this time so to them it looks like they are infertile.

This problem can be solved by knowing the exact ovulation day and the best way is to pinpoint the time using natural methods. It also important to avoid old egg and old sperm which are normally potentially defective and don't end up in a viable pregnancy.

And finally, building up sperm for the exact ovulation day can be an indispensable tip to falling pregnant successfully.
