40% Cause Infertility Due To Abnormal Sperm In Men
Infertility among men in recent years has been increasing, more and more Vietnamese men have been diagnosed with no sperm or poor sperm quality.
Modern science clarifies the cause of infertility, and identifies infertility rates between women and men, 40% for women, 40% for men, and the rest for infertility. unexplained birth.
According to WHO, in 2009 the average sperm index of men was 20 million / ml, but by 2010, this index decreased to 15 million / ml. This decline is tending to continue to increase
Sperm abnormality is classified into four main types: spermatogenesis (a condition where sperm count or absence of spermatozoa), motility, normal shape of spermatozoa, and rupture DNA fracture
With the development of modern medicine, each type of abnormal sperm has different directions of intervention.
And hope is constantly being opened to infertile infertile couples.
Little or no sperm
It is estimated that in men with abnormal seminal fluid, the rate of infertility may be as high as 10 - 20%. However, today many men who do not have sperm in semen can still have normal children.
Low sperm count: In this case, the treatment is not difficult. If medical interventions do not work, you may need artificial insemination. By doing this, the sperm will be filtered to leave the live, healthy, fast moving and pumped into the uterus. The effect is about 10 - 20%
In the absence of sperm: There is no sperm in the sample of sperm when ejaculating.
In this case, the treatment will be more complicated. But with current advances in infertility diagnosis and treatment, 70% of infertility cases can still have their own children. If semen analysis does not include sperm (in the case of normal sperm production, but there is a problem in sperm transport); The doctor may biopsy, suck a testicle, take testicle tissue, and scan a microscope to look for healthy sperm.
In the cases of testicular injections mentioned above, because immature sperm do not swim on their own, they cannot perform normal IVF fertilization (let sperm swim to the egg in a test tube), which forces doctors to master. Using a needle to suck sperm and pump directly into the ovule's cytoplasm (ICSI).
Sperm is not moving
Immobilized sperm is a state in which sperm is alive, but cannot move to the egg. In the past, when medicine was limited, these cases often required duplicate news. Until 2005, the method of sperm staining was introduced, allowing the identification of living sperm.
However, this method has certain limitations, because the determination is subjective, depending on the change in density after being dyed.
It was not until the introduction of the Laser Sperm Selection Method (LAISS) that it was truly a new breakthrough. Thanks to this method, the difference between sperm alive and dead without the use of any other chemicals. LAISS is recognized as the safest method, because it only affects the tail of the sperm, does not affect the head (where genetic material is stored), so that the ICSI technique is easily implemented and reaches a Fertilization rates are high for both patients who undergo surgery to collect sperm samples (MESA, PESA ...) and patients who are diagnosed with completely immobile sperm.
Sperm breaks DNA
Regarding genetic abnormalities in male infertility, sperm DNA fragmentation is currently the most common problem.
Sperm DNA fragmentation is the breaking and breaking of DNA strands that cause genetic information errors to reduce conception rate, affect embryo quality, increase the rate of miscarriage and birth defects.
However, no infertility treatment has been applied specifically to patients with fragmented sperm DNA. Sperm filtration and ICSI are still carried out in the same way as other normal infertility patients.
IVF Hopital Center, currently the first and only unit in Vietnam to apply advanced technology in the world, selects sperm by magnetic field (MACS). This method completely removes sperm fragmented DNA, only retains sperm with normal DNA for ICSI, and retains it for later use (freezing).
The MACS method is truly a turning point for Assisted Reproduction with the cause of male infertility, providing optimal efficiency for a IVF cycle.
At IVF Hopital Center, the latest advanced techniques are now applied such as LAISS and MACS, in order to increase the efficiency of in vitro fertilization. With a professional team.
