Does cryopreservation of sperm affect icsi fertilization rates in patients with non-obstructive azoospermia or cryptozoospermia?

RESULTS: The patient’s hormone levels remained menopausal until August 2011 when a peak estradiol level of 1166 pmol/L and FSH of 10.2 IU/L and LH morphology alone drives the current practice to transfer multiple embryos of 15.3 IU/ L was recorded indicating ovarian function. A decision was then to patients to maximize the chances of pregnancy. Unfortunately, this made to proceed with an IVF cycle and the patient was stimulated with an aro- practice leads to a high rate of multiple births and associated complica- matase inhibitor, letrozole, at 2.5mg from day 2 to 6 of a natural menstruation tions for both mothers and children.

OBJECTIVE: Our aim was to compare ICSI outcomes in patients with non-obstructive azoospermia or cryptozoospermia using fresh or frozen ejaculated or testicular sperm in order to determine possible differences.
DESIGN: A retrospective cohort study.
MATERIALS AND METHODS: Two hundred seventy four patients were evaluated from 1999-2011: One hundred twenty two TESE procedures were We compared ICSI outcomes during the first cycle in each technique per- formed according to the sperm origin (testicular/ejaculated) and processing (frozen/fresh): group 1a: frozen testicular (48 cycles), group 1b: fresh testic- ular (22 cycles), group 2a: frozen ejaculated (66 cycles) and group 2b: fresh ejaculated (138 cycles). The statistical analyses used were Kruskal Wallis RESULTS: In 76 of the TESE cycles (62%) sperm cells were found. No statistical significant difference was found in fertilization rate using fresh testicular or frozen testicular sperm (49.2% vs 52.7% respectively). The fertilization rate was significantly higher when ejaculated sperm cells were used (61.5%) in comparison to testicular sperm (50.3%), P¼0.002. Further-more, fresh ejaculated sperm were found to have better fertilization rates(64%) than frozen ejaculated (55.8%), P¼0.025, or frozen testicular sperm CONCLUSION: In women undergoing ART, resection of SM or the (49%), P¼0.002. More oocytes were injected with motile sperm in the fresh submucous component of IM restored fertility like the infertile controls’ ejaculated group (96.4%) than in the frozen ejaculated groups (87.9%) p¼0.03. Fertilization rates were significantly higher when motile spermswere used (62.5%) compared to immotile (30%), P¼0.001, regardless the CONCLUSION: In cases of cryptozoospermia frozen ejaculated sperm is inferior to fresh ejaculated sperm. In cases of non obstructive azoospermia we would recommend uncoupled TESE/OPU if no back up donor sperm is an option, since no major differences in fertilization rates were found, and A. K.
