How does the gender selection process work?
In this technique embryos are produced from eggs and sperm of the couple. On the third day, when the embryos have reached approximately 8-cell stage, we take one of the cells off the embryo (this can be done safely), and analyze its chromosomal make up. This then allows us to determine whether the embryo, from which the cell was taken, was female or male. Only embryos of the desired gender are then transferred into the uterus, making this a very reliable technique of sex selection.
