Gender Selection in Human embryos

History of gender selection in human embryos In the process of human history, newborn sex is often a welcome surprise, an uncontrollable aspect of the life cycle. With advances in technology, parents can not only know the sex of their children before they are born, but also can choose the gender of their children before embedding the womb. Since the early 1990s, Alan Handside and her colleagues succeeded in finding and transplanting female embryos for several couples at risk of X-linked recessive disorder, preimplantation genetic diagnosis (PGD) Are already available (Handyside, 1990).

According to the desires of parents, the gender selection of the IVF is often mistakenly called "gender selection" and is the process of selecting embryos through their sex chromosomes to produce male or female offspring throughout the in vitro fertilization cycle. In many cases, clinics can only select by gender from medical reasons related to x chromosome disease. The main method of gender selection is by a program called Pre-implantation Genetic Diagnosis (PGD). As part of the extracorporeal circulation cycle, many embryos are made, then the highest quality embryos are usually transplanted into the womb's uterus. PGD ​​is used to investigate genetic defects before implantation, but you can identify the sex of the embryo in the same process. The embryo of the desired gender is then selectively transplanted into the uterus of the female.

Selection of gender is an attempt to achieve the target gender by controlling the sex of future generations. It can be selected before and after embryo transfer and at birth. Preimplantation genetic diagnosis (PGD) and minimally invasive techniques are two new technologies to achieve embryonic selection. Identification of prenatal sex is done after implantation, ie blood test of fetal DNA from the 7th week of pregnancy. Microsoft's technology is a process of classifying sperm to increase the possibility that ova will be fertilized by sperm with targeted chromosome. A more accurate and accurate but more expensive and invasive technique is a method of producing and analyzing embryos in vitro or in vitro prior to implantation in a woman's uterus. PGD ​​is used for screening genetic diseases during embryonic stage. Unfortunately, the choice of gender is illegal in most parts of the world.
