Laser Assisted Sperm Selection of Viable Immotile Testicular Sperm in Azoospermic Infertile Men

Outcome of ICSI Using Laser Assisted Sperm Selection of Viable Immotile Testicular Sperm in Azoospermic Infertile Men: a Randomized Controlled Trial

This study aims to investigate the outcome of ICSI after using LAISS for selection of viable immotile testicular sperm in azoospermic infertile men.

Patients will be randomly assigned to 2 groups. In (LAISS) group, viable immotile testicular sperms will be selected before ICSI using laser assisted immotile sperm selection (study group). In (HOST) group, viable immotile testicular sperms will be selected before ICSI using hypo-osmotic swelling test (control group).

Inclusion Criteria:

• Eligible couples are those undergoing ICSI due to azoospermia with testicular biopsy positive for sperm (either fresh or cryopreserved) following testicular sperm extraction (TESE) or aspiration (TESA).

Exclusion Criteria:

• Cases with female factor infertility or woman age above 35 years will be excluded.
