What is IVMTS (In vitro Maturation of Testicular Sperm) ?
The recovered testicular sperm are sometimes so immature that they have minimal motility or none at all. According to Human Fertilization and Embryology Authority (HFEA) of UK Guidelines, non-motile sperm should not be used to inject the eggs. There is a risk that nonmotile sperm might not be alive. Such sperm may also carry a higher risk of chromosomal abnormality. In vitro Maturation of Testicular Sperm (IVMTS) involves keeping the testicular sperm in a culture medium under optimal conditions where they can attain physiological maturity and acquire motility.
