Today’s discussion is about, if artificial methods of fertilization used in infertile couples have any detrimental effects on the newborns. Interestingly small amount of increased risk of mental retardation is feared of to occur in the newborn, although risk of autism were almost excluded. The specific cause of such decreased mental capabilities are yet to unfold but proposed hypothesis is the need of traditional methods of at least 2 embryos implantation in utero, during the in vitro fertilization (IVF). More than one embryo implantation increases the risk of developing multiples like twins or triplets and this increased the chance of preterm or low birth weight problems. And these are already blamed for affecting mental functions sometimes. Henceforth, one embryo implantation instead might be a better solution.
Some also suspect ICSI i.e. intracytoplasmic sperm injection (where a sperm is injected inside the cytoplasm of the egg), during this procedure, method of natural selection can’t take place since the sperm is chosen by humans rather than nature, which may not be the healthiest sperm. Whereas in IVF generally sperms are allowed to compete in a dish in lab to fertilize the ovum and mimic the natural process that takes place in internal reproductive organs of women.
