Handling sperm motility problems
ICSI is a technique in which a healthy sperm is chosen and made immotile first.Then with the help of very fine injection syringe, the sperm is introduced into the egg so that the egg can be fertilized.
ICSI is very useful for patients with poor counts and problems and is must for TESA /PESA samples as sperms taken out from testis are nonmotile.
Even samples with no motile sperms can give pregnancies with ICSI.
Nowadays ICSI is more liberally used even in normal semen samples as it gives better pregnancy rates.
