Gender Selection Process :
- Preimplantation Genetic Testing (PGT):
- During IVF, multiple embryos are created in a laboratory through fertilization of eggs with sperm. After a few days of growth, a small sample of cells is removed from each embryo for genetic testing.
- The embryos are then screened to determine their sex, and only embryos of the desired sex are selected for transfer into the woman’s uterus.
- PGT is typically used in cases where there is a risk of passing on genetic disorders linked to a specific sex or when couples have a strong preference for a particular gender.
- Sperm Sorting:
- Sperm sorting, also known as sperm sex selection, involves separating sperm based on their X or Y chromosomes, which determine the sex of the resulting offspring.
- Techniques such as flow cytometry or density gradient centrifugation are used to separate sperm based on their DNA content, as sperm carrying X chromosomes (responsible for female offspring) have slightly different DNA content than those carrying Y chromosomes (responsible for male offspring).
- The sorted sperm are then used for artificial insemination or in vitro fertilization to increase the likelihood of conceiving a baby of the desired sex.
- Sperm sorting techniques are less commonly used than PGT and may have lower success rates.
