摘要: Purpose: To compare fertilization and pregnancy rates of fresh frozen-thawed testicular sperm injections (TESE-ICSI). Methods: Sperm collected from the testes 28 azoospermic patients by an open biopsy technique was used for initial ICSI or cryopreserved. Results: Fresh-sperm treatment (28 cycles) resulted in a 58.1% rate 32.1% clinical per embryo transfer, while (24 subsequent had 54.5 29.2%, respectively. The PR lower using nonobstructive azoospermia (9.1%) than obstructive (46.2%). declined to 0% upon fourth attempt. Conclusions: Fertilization, cleavage, were unaffected use. A 57.1% cumulative achieved latter. significantly patients.
