Clinical Trial Summary

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).

Eligibility

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.

Related Conditions & MeSH terms

• Azoospermia
• IVF

Intervention

Device:
• Laser Assisted Immotile Sperm Selection
LAISS will be performed using diode laser system at the lowest working power with a single laser shot at the lower one third of the sperm tail. If sperm tail curling occurred, the sperm is then viable and will be utilized for ICSI after immobilization in PVP.

Procedure:
• Hypo-osmotic Swelling Test
HOST will be performed by transferring immotile sperms from incubation droplet into HOST droplet, with any sperm showing tail swelling will be identified as viable and will be utilized for ICSI after immediate transfer and immobilization.
