Background: Sperm cryopreservation becomes a relatively routine process in assisted reproductive centers. However, there must be ensured quality of washed human normal sperm and cryopreservation to successful fertilization. Objective: To evaluate the quality of washed human normal sperm after cryopreservation. Subjects and method: 30 normal semen samples, each sample was divided into two parts for washed and unwashed spermatozoa. All samples were cryopreserved in 1, 2 and 30 days. Evaluating and comparing the quality of sperm before and after which washed, pre-cryopreservation and post-cryopreservation between the groups were performed. Results: The quality of sperm after washing was more significantly improved than before washing. Post-cryopreservation, the quality of sperm was reduced time by time but within an accepted limitation. There was not a significant difference between the two ways of preparation before cryopreservation. Conclusions: The quality of sperm at post-cryopreservation was reduced (both washed sperm and unwashed sperm). The quality of washed sperm is reduced continuously with time, but there was no difference between the two studied groups.

The authors give first experience on the utilisation of homograft with dura mater and bone from homograft Bank of Cho Ray hospital in the repair of dura mater and bone defects in 17 craniotomies with encouraging results. They hope to get in the future more convincing results

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.
