Once married, every couple expects to have their own babies. It is their first and foremost dream. But it is impossible to predict when an individual couple will succeed in achieving pregnancy.

And if you have been having sexual intercourse two or three times a week, at about the time of ovulation without any form of birth control for a year or more and have not become pregnant, you meet the definition of being "infertile". Couples who have never has a child are said to have "primary infertility", those women who have become pregnant at least once, but are unable to conceive again said to have "secondary infertility". Eminent Unani Hakeem describes that the chances of achieving pregnancy for a couple in a given cycle depend upon many factors, and the most important ones are: - ;           The age of the woman. As age increase the number of eggs and their quality starts decreases. ;           Frequency of intercourse, couples who have less frequent intercourse have diminished chance of conceiving. ;           "Trying time" that is how long the couples have been trying to get pregnant.
