While you may have conceived your first child with ease and deliver her healthy afterwards, you are still likely to become a patient of a condition we call secondary infertility.

A strange condition it is, secondary infertility is characterized by the inability to conceive after a year of unprotected sexual intercourse following the delivery of the first child. The causes involve both of the participants yet for the quarter of the reasons studied, causes are multi-factorial.

The primary factor in secondary infertility is age.

It is known that women, while being conceived are already equipped with the precise number of egg cells that will mature as they age.

The pick release of these egg cells occurs during the midyears woman commencing at her twenties. Then comes menopause, which is simply the lack or absence of egg cells since they were already released and used previously. If there were any left during the latter years towards menopause, the egg cells are likely to be unhealthy and incapable of becoming fertilized, even with well-timed intercourse. At these years (age 45 and above), the possibility of forming a zygote is only 6%.

While we may presume that some more eggs may be left from the whole batch, they still would not be able to fertilize since they have been for long, exposed to environmental hazards that are contributors to the degeneration of egg quality.

Lesser studies on male secondary infertility were conducted though. Yet the link between the lessened quality of sperm cells is likely to be the main and determining reason.

Another condition why secondary condition appears is the introduction of a new partner. If a male or female were able to produce a child previously, changes in a new partner's nature may severely affect the capacity to conceive once more.

To complete the known reasons to secondary infertility, it would be best that we view some troubles concerning pathology.

Essentially, the problem focuses on the interruption of any of the vital steps by which fertilization occurs.

For one, healthy sperm and egg cells must be produced. If the problem occurs in here chances are, either of the couple may have developed secondary infertility.

Second, a supportive environment must be provided. In the absence of a favorable place to nurse the zygote, there is no sense to fertilize egg and sperm cells.

Again, we must understand that there are many conditions that will intensify the chance of becoming infertile. All these may develop after the first successful pregnancy.
