Inability to conceive even after having unprotected sex for almost a year is termed as infertility.  Earlier the treatment was difficult; but recent advancement in medical science such as introduction of female infertility drugs and development of techniques like assisted reproductive technology has made the treatment possible now.

Before administering female infertility drugs it is imperative to identify the cause of infertility.  These drugs are a kind of hormonal therapy; wherein the female ovary is stimulated to produce eggs.  The major cause why a woman is unable to conceive is her inability to produce eggs or in other words there is no ovulation in woman.

In the absence of ovulation there are no eggs and hence the male sperm when reaches the uterus has nothing to fertilize. The female infertility drugs either stimulate the female hormones or even act as hormones to produce the eggs.

Clomiphene and Serophene are the two most commonly used female infertility drugs; the drug Clomiphene stimulates the pituitary glands to produce follicle stimulating hormone (FSH) which in turn stimulates the ovary to produce eggs.  In many of the cases during ovulation two or more eggs are released increasing the chances of having twins.
There are other drugs taken which are FSH, these are administered into the body through injection; these drugs also helps in ovulation but before taking, it should be properly sterilized.

Though these drugs will help in conception in most of the cases; but everything depends how your body react to these drugs.  There are about 20% cases where the doctor is not able to find out the cause of infertility. Nevertheless if you are facing such a problem take proper medication as per the doctor’s advice. If medication fails then there are artificial ways by which you can enjoy motherhood. So, nothing to worry about.
