“…The recovery rates of intact spermatozoa are highly dependant on the pre-freezing sample quality (de Paula et al, 2006). Poor quality semen may be more prone to DNA damage and cell death after cryopreservation than normal semen samples and thus have lower fertilizing capacity (Borges et al, 2007). It has been shown that reactive oxygen species (ROS) production impacts membrane fluidity and the recovery of motile, viable spermatozoa after cryopreservation.…”

“…Although most studies comparing ICSI using fresh or thawed spermatozoa do not reveal differences in reproductive outcome (18,19), it appears that ICSI performed with motile spermatozoa gives better results with respect to immotile ones (20,21). As a matter of fact, ICSI performed using cryopreserved spermatozoa from patients with different types of cancer or pathologies gives rise to variable clinical pregnancy and live-birth rates (12,22).…”

Objective: To evaluate post-thawing sperm parameters in a large series of men cryopreserving for different cancers and oligospermia. Design: Retrospective observational study. Setting: Semen cryopreservation laboratory. Patient(s): Six hundred twenty-three patients undergoing semen cryopreservation for cancer or oligospermia who discontinued banking. Intervention(s): None. Main Outcome Measure(s): Postcryopreservation sperm motility and viability. Result(s): In oligospermic men, recovery of motile sperm after cryopreservation was possible in only a few out of the 219 samples cryopreserved for this problem. Similarly, independent of the reason for which cryopreservation was required, if one basal semen parameter fell below the 5th percentile of the World Health Organization reference values, recovery of motile and viable spermatozoa after thawing was low. Among samples cryopreserved for cancer, those with testicular cancer showed the lowest basal semen quality and recovery after thawing. In cases of hematological cancers or other types of cancers, motility recovery was similar to that of non-cancerrelated samples. Receiver operating characteristic analyses demonstrate that basal progressive and total motility predict the recovery rate of motile sperm after thawing with high accuracy, sensibility and specificity. Conclusion(s): Our study demonstrates the ability of prefreeze semen parameters to predict cryosurvival in terms of sensitivity and precision. Using this information, the clinician could perform appropriate counseling about the future possibilities of fertility for the patient. (Fertil Steril Ò 2013;100:1555-63.

“…Several reports have described the lack of knowledge on the part of oncologists about ART (8)(9)(10). The success rates of IVF and ICSI treatments using cryopreserved semen are currently almost as high as those using fresh semen (11,12). The use rate of cryopreserved semen differs widely between the different studies.…”
