OBJECTIVETo search for an optimal protocol and freezing conditions for the cryopreservation of microamount round spermatids of the mouse.
METHODSWe compared the survival rates of frozen-thawed microamount round spermatids of the mouse achieved by vitrification or standard slow freezing with different concentrations of glycerol (5, 7, or 9%) and different lengths of equilibrium time (0, 15, 30, 45, or 60 min).
RESULTSUnder the conditions of 7% glycerol and 30 min equilibrium, both vitrification and standard slow freezing achieved high survival rates of spermatids, and the former obtained an even higher rate than the latter ([72.9 ± 15.4]% vs [58.2 ± 17.7]%, P < 0.05).
CONCLUSIONA high rate of frozen-thawed microamount round spermatids of the mouse can be achieved by vitrification under the conditions of 7% glycerol and 30 min equilibrium.

Objective To analyze the outcomes of frozen-thawed blastocyst and cleavage embryo transfer after whole embryos cryopreservation. Methods The data of 489 IVF-ET cycles in reproductive medicine center of our hospital from September 2012 to August 2013 were analyzed retrospectively. Whole embryos cryopreservation in 214 patients were carried out with vitrification method and served as group A , 275 cycles performed fresh embryo transfer were served as group B. Then group A and group B were subdivided into group A1 (83 cycles),group A2 (131 cycles), group B1 (120 cycles)and group B2 (155 cycles)according to blastocyst transfer or cleavage-stage embryo transfer. The clinical outcomes of all groups were compared each other. Results The pregnancy rate and embryo implantation rate in group A1 were significantly higher(71.1% ,53.0%)than those in group A2, B1 and B2 (A2 group: 57.3%, 34.0%, B1group: 55.0%,42.1%, B2 group: 52.9%, 32.7%,respectively)(P<0.05). The embryo implantation rate in group B1 were higher than those in group B2 (P < 0.05). Conclusion F-ET after whole embryos freezing could significantly improve the embryo utilization rate and clinical pregnancy rate. Frozen-thawed blastocyst transfer could get better clinical outcomes than frozen-thawed cleavage-stage embryo transfer.
