The men born by fertilization are sperm evil

The techniques of fertilization are increasingly used to achieve a pregnancy, although this does not represent damage to the mother or to the baby, in the future they could have any effect.

A study published in the journal of medicine, Human Reproduction says that the sons of men subjected to techniques of fertilization have lower quantity and quality of sperm than those who were born in the traditional way.

The report details that this occurs in men who, due to infertility, were submitted to the treatment of intracytoplasmic sperm (ICSI for its acronym in English).

The study

The researchers analyzed a group of 54 men between 18 and 22 years born by ivf, and another group of children born spontaneously.

As a result, it was found that those who were born by techniques of fertilization had almost half of the concentration of sperm and two times less in sperm count and total and total.

In comparison with those that were born spontaneously, the ICSIs were three times more likely to have sperm concentrations below 15 million per milliliter of semen.

ICSI

This procedure was initiated in the Centre of Reproductive Medicine of the Vrije Universiteit Brussel (VUB), in Brussels, Belgium, by Professor André Van Steirteghem, one of the co-authors of this research.

On 14 January 1992 the first baby was born by injection and by 1996, 54 births were registered.

ICSI involves injecting sperm from the father directly in the egg of the mother in a laboratory. Subsequently, the fertilized egg is placed in the belly to achieve pregnancy.

This is a very effective method for those men with sperm of low mobility, because the best are chosen and those are injected in the ovum.

The results are not unexpected

As always Steirteghem and his colleagues knew that the child runs a high risk of inheriting fertility problems from the father, although the results of ICSI could not be confirmed in its entirety due to its young age.

“These results are not unexpected: before ICSI have been done, the expectant parents have been informed that it is very possible that their children may have problems with semen and sperm, as well as their parents”. For all parents, this information was not a reason to refrain from passing by the ICSI, since they said: “If this happens, the ICSI will also be a solution for our children,”, recognizes Professor Van Steirteghem.

Explains that the results of ICSI indicate that a degree of “sub-fecundity” was transmitted to the children, although are necessary more studies, because, although genetics may be important in infertility, other factors may also be involved.

“These findings highlight the need to continue and expand other follow-up studies of children conceived through assisted reproductive techniques, for example, analysis of paired samples of parents and children, and see a greater number of descendants. A challenging project for the VUB however, the health authorities and the funding agencies must provide the means to answer questions about the effects of genetics, mode of conception, patterns of fetal growth and birth weight on the fertility of the men of the ICSI “, he concludes.

“do Not be afraid to approach the patients, even though they teach us in school that we should be a little isolated from the emotions of the patients, I think that, as a human being, you must feel this pain, you must prove those wins and take advantage of these sad moments That makes you a better doctor, scientist and, above all, a human being “, he emphasizes.
