Viability and fecundity of human semen specimens cryostored and transported at 5 degrees C using the Bio-Tranz shipping.
This study was designed to assess the viability and fecundity of semen stored at 5 degrees C for 24 hours using the Bio-Tranz shipping system. Semen specimens were assessed for motility and sperm membrane integrity at the time of collection and 24 hours after storage in the Bio-Tranz. In group 1 (n = 61), specimens were diluted in TYB, processed and used for intrauterine insemination (IUI), leaving an aliquot for storage for 24 hours in the Bio-Tranz. In group 2 (n = 67), specimens were diluted in TYB, stored for 24 hours in the Bio-Tranz and then processed and used for IUI. In both groups, the total motile sperm used for IUI was similar and the women that underwent IUI were standardized for ovulation prediction and time of insemination. The overall sperm characteristics between the two groups were within normal range. Significant decreases were noted in sperm motility and membrane integrity in both groups after storage. Similar pregnancy rates were obtained between the two patient populations. The use of the Bio-Tranz shipper is extremely convenient for patients requiring semen evaluation, cryostorage or IUI and other assisted reproductive technologies.
