131 SPERMATOGENESIS MONITORING WITH AIM TO SELECT OPTIMUM PERIOD FOR PERFORMING EXTRA-CORPOREAL FERTILIZATION WITH SPERMS TAKEN FROM DONOR CURED OF CHRONIC PROSTITIS

by vitrification method at our own cryobank, where they can be stored for years. Samples were cryopreserved as follows: each aliquot was diluted in the same volume of cryoprotectant medium consisting of 15% glycerin, 2% sucrose, 0.4% human serum albumin in aqueous solution. Cryoprotectant medium was added sequentially drop by drop, with constant mixing. Each aliquot was then placed in cryotubes, frozen and transferred to a liquid nitrogen tank until use. Samples can be stored for years and used later for insemination. Results: In the Russian Federation we are establishing the first human sperm bank for cancer patients. The analysis of semen samples indicate that oligozoospermia is present in 76.20% of the semen samples, asthenozoospermia in 57.14% of the samples; only 23.8% of the samples were normozoospermic. Conclusion: Recent advancements in the field of fertility preservation have revolutionized the options available to those who elect to maintain their reproductive potential. Fertility preservation should be an integral part of improving the quality of life in cancer survivors; however, it is neither possible nor ethical to recommend the same recipe for every cancer patient. The primary goal is to cure the cancer, even if the treatment causes sterility.
