A couple that has been unable to conceive after one year of regular unprotected sexual intercourse is considered infertile. Today, 25 per cent of couples are infertile. There is a worldwide emotional epidemic of infertility.

In Nigeria, infertility, which used to be a small area of gynaecology practice, has now become a huge discipline with several doctors devoting their clinic solely to the practice of treating infertility.

As we get older, our ability to get pregnant decreases. Only one per cent of teenagers are infertile, while a large majority of infertile couples are in their 30s. It is well documented that from our teen years when the last thing we wanted was a child, to our mid 30s when we are finally secure enough to start our family, our ability to conceive decreases almost by 25 per cent.

We know that in all species, there is a very short window - in fact, a matter of days - during each month that the female is fertile and can get pregnant through sexual intercourse. The timing of sex is therefore very important if a species is to have an efficient and high fertility rate.

In humans, women go through a period of 14 days when the follicle in the ovary develops. This starts from day one of the menstruation until the egg is sufficiently mature and ready for ovulation. Once the egg is released at ovulation, there is another 14-day period that it can be fertilised. If sexual intercourse occurs at the right time, then the embryo grows and implants in the uterus, or womb. If sexual intercourse occurs at another time other than the ovulating period, it is very unlikely that the woman will get pregnant.

Animals go through what is described as an "estrus" cycle or "heat." Humans go through a menstrual cycle. Apart from other hormonal variations, one significant difference between humans and animals is that the female sex hormone, estrogen, which increases just before ovulation in animals, is the trigger factor for their sex drive. This hormone is responsible for producing eggs. In other words, animals do not desire to have sex unless there is an egg to be fertilised in the female's womb.

In humans, sex desire is much more complex and is not driven by the female sex hormone, estrogen; but by the male sex hormone, testosterone. This is unique in the animal kingdom and it is especially a human phenomenon.

The small amount of testosterone that the female makes is enough to generate sexual drive in her. It is only few females that recognise the slight increase in testosterone around the ovulation period to enable them deliberately initiate sex at the appropriate time to get pregnant.
