It is a known fact that the advanced and most evolved class of animal kingdom – the homo sapiens reproduce sexually. But there are cases where humans reproduce through asexual modes. Asexual reproduction in humans is carried out without the immediate use of fertilization of the male and female sex cells (the sperm and egg). It is carried out by fusing a few parts of human sperm, embryo, the egg or unnatural genes to reproduce a new human fetus which further undergoes maturation and development depending upon the medical procedures. It is usually carried out in case of infertility using the assisted reproductive treatment such as the IVF(Invitro fertilization).
However, there is a mode of asexual reproduction which occurs naturally in a woman’s body which is known as the monozygotic twinning. It is a kind of asexual reproduction which has been used for decades in the IVF cycles, a type of human cloning. Other types of asexual reproduction that is carried out artificially as part of IVF is the cloning by somatic cell nuclear transfer.
The latest advancement in the field of medicine has given rise to a new breakthrough in the domain of asexual reproduction referred to as the ‘3-parent-embryo’ which involves the use of several techniques, for instance, the mitochondrial transfer which is again another kind of cloning. The concept is that three parents can be used to produce one single embryo if the mitochondria, which are usually found in the female egg, is replaced by the mitochondria from the third party in case of any defect.
