Chat determining sex
A number of methods use the size of differential to sort semen into X- or Y-bearing sperm.
Sperm sorting is based on the theory that the lighter Y sperms will collect separately from the heavier X sperms."The sorted sperm can then be used for artificial insemination where sperm is introduced into a woman's uterus at the time of ovulation," explains Sascha.
If the Y-bearing sperm penetrate the egg, then the baby is a boy (XY).
If the X-bearing sperm penetrate, then the baby is a girl (XX).
Down syndrome, one of the most well-known genetic conditions, is caused by an extra copy of chromosome 21.
Generally, the larger the extra chromosome is in size, the more severe problems it will cause.
But do these methods open the flood gates to creating designer babies, and are these procedures readily available? When you fall pregnant, you may expressly (or quietly) wish for a certain gender.
But it isn't actually up to the woman to choose the sex of the baby.
It can also be used in women who have recurrent pregnancy loss due to a chromosomal abnormality, women of advanced maternal age and women with repeated in-vitro fertilisation (IVF) failure," says Sascha. Sex selection (the ability to choose the sex of a future child) is now technically possible.Something that used to be left to nature is now in our hands.One of the most accurate methods of sex selection is pre-implantation genetic diagnosis (PGD), which works similarly to IVF.It allows couples the chance to screen embryos before they're implanted.
