Normally, fertilization occurs when one sperm gets into the fallopian tube and attaches to the egg. Every sperm cell has one chromosome, the X chromosome or the Y chromosome. If the chromosome is X, then the fetus is male. If the chromosome is Y, then the fetus is female.
However, too much sperm count will result in the buildup of sperm cells (polyspermy). Polyspermy can produce extra chromosomes (combination chromosomes) that can compromise the sex determination of the fetus, due to abnormal chromosomes or triploid chromosomes, such as XXX, XXY, or XYY.
According to a 197 report by Nora Blacwell and colleagues, the tripoloid chromosome will fall into the uterus and last only a few hours. This is why the accumulation of sperm in the egg can result in miscarriage and failure of pregnancy.
In addition, Patricia Jacobs and colleagues followed reports on the origin of triploid chromosomes in humans in 1978 at maternity homes in Hawaii. As a result, 21 out of 26 fetuses had a miscarriage due to triploid chromosomes.
Triploid chromosomes are relatively common in humans. It is estimated that it affects 1-3 percent of all conception.
To know the cause of recurrent miscarriages and make it difficult for you to have children, doctors usually recommend that men perform sperm quality tests. Thus, you can make treatment or lifestyle changes that can improve the quality and quantity of your sperm to be normal.
