Deep-cryopreservation (at –196oC) of human spermatozoa in glycerol, GEYC and sperm freeze media shows that after preservation, the quality of spermatozoa is the same in GEYC and sperm freeze but higher in glycerol medium with statistically significant level (p<0.01). The CSF of deep-cryopreservation of human spermatozoa in GEYC and sperm freeze media reached an efficacy of CSF  50%.

In GEYC medium self prepared in our laboratory, 30 deep-cryopreserved samples of human spermatozoa showed that the quality of preserved spermatozoa met the criteria of AATB. GEYC medium could be prepared at our laboratory with low cost and suitable to Vietnam’s conditions.
