Microsurgical-assisted testicular sperm extraction (m-TeSE) - Group A
A longitudinal incision of 3cm was made along the scrotal raphe using a scalpel. Surgical dissection proceeded layer by layer. The testis was separated from the surrounding dartos and luxated outside the scrotal sac. A longitudinal incision was made in the tunica vaginalis to allow complete exposure of the tunica albuginea. Two Vicryl 2-0 traction sutures were placed 0.5 cm cranially and caudally to the testicular equatorial line, which was subsequently incised with a scalpel for 3/4 of the testicular circumference. In M-TESE, through the operating microscope, a direct examination of the testicular parenchyma was performed under magnification (20-25x). Multiple testicular specimens were excised. The same procedure is performed on the contralateral side, where instead of the operating microscope, the surgeon uses surgical loupes for magnification (3.5 - 5x).
Microscope
The microscope provides a direct examination of the testicular parenchyma at 20-25x magnification.
Testicular sperm extraction performed with surgical loupes (l-TeSE) - Group B
A longitudinal incision of 3cm was made along the scrotal raphe using a scalpel. Surgical dissection proceeded layer by layer. The testis was separated from the surrounding dartos and luxated outside the scrotal sac. A longitudinal incision was made in the tunica vaginalis to allow complete exposure of the tunica albuginea. Two Vicryl 2-0 traction sutures were placed 0.5 cm cranially and caudally to the testicular equatorial line, which was subsequently incised with a scalpel for 3/4 of the testicular circumference. In M-TESE, through the operating microscope, a direct examination of the testicular parenchyma was performed under magnification (20-25x). Multiple testicular specimens were excised. The same procedure is performed on the contralateral side, where instead of the operating microscope, the surgeon uses surgical loupes for magnification (3.5 - 5x).
Surgical loupes
Surgical loupes offer magnification of 3.5-5x.
