We performed this study to evaluate use of fresh and frozen sperm samples in non-obstructive azoospermia microdissection testicular sperm extraction micro-TESE-ICSI treatment. In 43 participants we used fresh sperm and frozen sperm in the remaining 39 cases. Neither the age of male partners FSH concentrations were
Using Fresh and Frozen Testicular Sperm Samples in Couples Undergoing ICSI-MicroTESE Treatment
An update on sperm retrieval techniques for azoospermic males
The introduction of the technique of intracytoplasmic sperm injection to achieve fertilization, especially using surgically retrieved testicular or epididymal sperm from men with obstructive or non-obstructive azoospermia, has revolutionized the field of assisted reproduction. The techniques for the retrieval of spermatozoa vary from relatively simple percutaneous sperm aspiration to open excision testicular biopsy and the more invasive Micro-TESE. The surgical retrieval and cryopreservation of sperm, especially in men with non-obstructive azoospermia, to some extent ensures the availability of sperm at the time of intracytoplasmic sperm injection. In addition, this strategy can avoid unnecessary ovarian stimulation in those patients intending to undergo in vitro fertilization-intracytoplasmic sperm injection with freshly retrieved testicular sperm when an absolute absence of sperm in the testis is identified. Several different methods for the cryopreservation of testicular and epididymal sperm are available.
Using Fresh and Frozen Testicular Sperm Samples in Couples Undergoing ICSI-Micro TESE Treatment
An update on sperm retrieval techniques for azoospermic males. Sandro C. The use of non-ejaculated sperm coupled with intracytoplasmic sperm injection has become a globally established procedure for couples with azoospermic male partners who wish to have biological offspring. Surgical methods have been developed to retrieve spermatozoa from the epididymides and the testes of such patients.
