ABSTRACT
<p><b>OBJECTIVE</b>To investigate the effectiveness of testicular sperm cryopreservation in male fertility preservation by evaluating the clinical outcome of ICSI cycles with frozen-thawed testicular sperm for azoospermia patients.</p><p><b>METHODS</b>We retrospectively analyzed 96 samples of cryopreserved testicular sperm obtained by testicular biopsy, vasovasostomy (V-V), vasoepididymostomy (V-E) , of which 55 were subjected to 60 ICSI cycles with frozen-thawed testicular sperm. We evaluated the rates of sperm recovery, fertilization, cleavage, transferable and good-quality embryos, clinical pregnancy, pregnancy outcome, and health of the newborns.</p><p><b>RESULTS</b>All the frozen testicular sperm samples were recovered successfully. The rates of fertilization, 2PN fertilization, cleavage, available embryos and good-quality embryos were 77.6, 69.4, 99.4, 84.5 and 40.8%, respectively. There were transferable embryos in all cycles. Fresh embryos were transferred in 52 of the 60 cycles, with the clinical pregnancy rate of 57.7% (30/52), including 19 singletons and 11 twins, and the rates of implantation and miscarriage were 38.7% (41/106) and 3.33% (1/30). Up to the present time, there have been 20 healthy newborns, including 12 boys and 8 girls, and another 13 ongoing pregnancies. No birth defects have been found so far.</p><p><b>CONCLUSION</b>Desirable clinical outcomes can be obtained from ICSI cycles with frozen-thawed testicular sperm, and testicular sperm cryopreservation is an effective method of fertility preservation for azoospermia males.</p>
