STRESS, DRUGS AND CIGARETTES ARE AMONG THE MAIN CAUSES OF THE PROBLEM
The infertility may be becoming a bigger problem for men than for women. In search of the European Society of Human Reproduction and Embryology, in 52% of cases, treatment to combat male infertility has been overcoming the technique used in women who want children and can not.
Traditionally, in the same proportion infertility affects both sexes. But according to the study in 2005, the fall in the quality of sperm - because of environmental toxins - is among the factors contributing to the increase in male infertility.
According to the specialist in assisted reproduction, Dr. Marcos Sampaio, environmental factors have become very concerned. "Urban growth afloat, the increasing number of cars on the streets, the use of insecticides and solvents, all these factors could affect the fertility of human beings. It is a public health problem that deserves attention, "he explains.
In Brazil, data from the Ministry of Health show that men are responsible for 40% of cases of sterility. In Origen Clinic, which specializes in assisted human reproduction, the number is the same. Among the most common causes of male infertility are abnormal dilation of the veins of the testicles, decrease in the failure of the testes, hormonal changes, surgical trauma, the production of anti-sperm antibodies and genetic disorders. Alcohol, tobacco and drugs also lead to infertility.
"The psychological aspect should also be taken into consideration. Stress can lead to changes in central nervous system, causing a weakened form of pituitary function. Thus, the production of hormones that act in the testis decreases and there is a decrease in production of sperm, "explains the expert Marcos Sampaio.
Espermograma
The espermagrama is the first examination to be done when there is suspicion of male infertility. From the analysis of semen, there are the quality and vitality of spermatozoa. To reach a definitive diagnosis, the examination should be repeated at least three times, every 90 days, as the sperm pass through a process of maturation and renewal every 72 hours.
When the result of the test detects problems in quality or quantity far below the need for a natural pregnancy, you can use the techniques of assisted reproduction such as artificial insemination and in vitro fertilization. |
