--------------------------------
Materials and Methods:

A total of 84 cycles of ICSI were performed with fresh or frozen-thawed testicular spermfrm hypospermatogenesis patients. Of these, 55 cycles (65.5%) were performed with fresh sperm, and 29 cycles(34.5%) were performed with frozen-thawed sperm. Testicular tissue was frozen with the programmed cell freezer(Cryomagic I, Miraebiotech, Seoul, Korea).

Freezing and thawing procedures
Slow freezing and thawing: A slow-rate freezing protocolwas employed, as described by Lassalle et al. (1985),using a programmable freezer (Cryomagic, Mirae Biotech, Seoul, Korea).

Cryomagic - Automatic Cryopreservation Freezer

Introduction

Our most advanced controlled rate freezers are used to store a variety of critical samples of biological freezing or thawing works. The Cryomagic™ Freezers are available in 3.0 liter & 30 liter sizes. Each model includes a separate control unit, which can create and modify multiple freezing protocols with a compact thermal printer. A DPS-1800 Digital Pump can be chosen as an option, but it is standard to the 3.0 liter chamber. Unlike other analog pumps, the DPS-1800’s digital sensing system secures the samples and device itself preventing from liquid Nitrogen shortage or overheating. Comprehensive CMG 2003 software allows the user to store or retrieve the program files to a PC. At the same time the program offers password controlled access on multiple user levels, time and date stamping, program preview and verification before running and data storage for the last runs for subsequent printing.
