It is known that human reproduction is relatively ineffective. Each month, a couple with no problems conceiving, it is only 7% chance of achieving pregnancy. The chances are further reduced in those with fertility problems, even to this objective cannot be spontaneously in 15% of cases.

However, advances in assisted reproduction were able to reverse the fate of many. From birth in 1986 of the first IVF babies in Argentina until the present, assisted reproduction remained steady growth.

In less than 25 years, diagnosis, description of the various disorders that may affect reproduction, the selection of eggs and sperm and the implementation of assisted reproductive technology (including advances) allowed better results when implementing an action strategy.

In acaridae is still possible to preserve fertility in cases where the woman must receive cancer treatments like chemotherapy or radiotherapy, to avoid the inheritance of disease from the selection of embryos, defer motherhood through the cry preservation of eggs and increasingly control more effectively the multiple gestation, “said Gabriel Fishbone, head of the Center for Reproductive Medicine in Gynecology and Reproduction Studies (Cagier).

However, the degree of effectiveness of these innovations also depends on a crucial variable: the age of the woman. Despite scientific advances, the female biological clock remains intact. “From the age of 35 fertility declines and increases the risk of genetic abnormalities in offspring,” said Fishbone.

That is why a couple does not realize that pregnancy after a year of searching should consult a reproductive specialist, a diagnosis and begin the necessary studies without further delay. Especially if it comes to women over the barrier of 35.

First is a history in which notes all the antecedents that may be related to the difficulty of achieving a pregnancy, for example, registration of sexually transmitted diseases, surgery, chronic problems, drug use, alcohol or cigarette.

Through control of temperature, hormone analysis and implementation of translational ultrasound, we studied whether the woman is ovulating normally. “Then there is a ray of the uterus and fallopian tubes called a hysterosalpingogram, which evaluates the path traveled by sperm and egg to meet,” he added.

Also important is the Gynecologic ultrasonography to rule out uterine fibroids that may affect the implantation or cause abortions.

The man, meanwhile, should be studied simultaneously, and that male problems represent 50% of cases. In this case seeks to establish if your semen is normal and if after intercourse, the sperm find the underlying cause of the uterus and cervix ascend. It is recommended to make a study of compatibility between sperm and cervical mucus as, of course; they must swim through the substance in his rise to the egg.

This battery of studies to identify the causes of reproductive disruption by 80%, 20% balance will be elucidated by more complex studies such as immunological, genetic or infectologists.

In conclusion, Fishbone said, “time, diagnosis and treatment are the main variables along the path to meet the goal of parenting.”
