Not all the sperms of a person with weak spermatozoa are weak, and it is sufficient to select one normal sperm among them, so the success rate is very high, about one or two times.
In vitro fertilization (IVF) is a procedure in which sperm and eggs are taken out of the body and fertilization is completed outside the body to form a fertilized egg with early development, which is then injected into the mother’s uterus to continue development and form a baby. Weak spermatozoa is defined as having less than 30% of spermatozoa in forward motion and almost no symptoms other than a low chance of pregnancy.
In vitro techniques for low sperm or weak sperm motility, the possibility of having a baby is very low, and it is necessary to improve the chances through assisted reproduction technology, which removes one of the sperm with the strongest growth capacity in the semen through a very thin pipette and injects it into the egg cell, and this technology is very mature nowadays, so the success rate is very high.
