A gene that may explain why men are not able to impregnate a woman was found.
NR5A1 gene mutation was found in a cell that infertile men (infertile) in a small percentage. American Journal of Human Genetics reported.
Scientists from the Pasteur Institute in France and the University of London said that the findings could help physicians to further explore the condition of a man’s infertility.
Experts are hoping they will find the genes that the other weak.
In many cases, doctors can not find the cause of infertility in a man. Whereas half of the cases non-pregnant women caused by this fact.
Infertility in men occurs more commonly in certain families and this made the experts conclude that genetic factors may influence this situation.
Recent research to see that the genes already known this and there are men and women turned out to cause infertility.
NR5A1 tekait with damage to the testicles or ovaries.
This finding states that although there is no physical evidence of these problems, damage to this gene causes complete inhibition of sperm formation.
The experts are monitoring about 315 genes of healthy men who were unable to produce sperm.
They found a mutation in a gene and a more detailed study reveals the existence of sex hormone changes and in one case, mild abnormalities in cellular structure occurs in the testicles.
Scientists from the UCL Institute of Child Health in London and the Institute Pasteur in Paris said, “We conclude that almost 4 percent of men who can not produce sperm carrying the gene NR5A1 has mutated.”
Although these findings may only explain a little of the many cases of infertility in men, believed to be a description of these findings for physicians to deal with the problem yanga there.
Senior Lecturer in Andrology at the University of Sheffield Dr. Allan Pacey said that there was “little sense of shame” concerning the disclosure of the issue of these genes behind male infertility.
“With the complexity of the process of sperm production, it seems that many genes would be involved in and therefore likely to damage genes tekait directly with male infertility,” said Allan.
Allan continued, although this defective gene may only occur on a little man, “We need research like this so that we can obtain enough to organize like a case of infertility problems and make diagnoses based on genes.
