RESUMO
We applied the technique of ooplasmic elongating spermatid injection to the treatment of non-obstructive azoospermia. Mature oocytes were injected with elongating spermatids isolated from testicular biopsy material obtained from 13 non-obstructed azoospermic men. Seventy-three oocytes were successfully injected with elongating spermatids and were then cultured for 36 h. At 13 h post-injection 68 oocytes were found to be activated and 52 of them were fertilized. Forty-one 2- to 4-cell stage embryos developed from normally fertilized oocytes were transferred. At least two embryos were transferred to each female partner. Two pregnancies were achieved. Elongating spermatid injection may have a role in the treatment of non-obstructive azoospermia.

Penile prostheses are a well-established form of therapy for erectile dysfunction. We report our experience with 333 cases using the Mentor Alpha I inflatable penile prosthesis. With a follow-up period of 15.4 months, there were 25 (7.5%) complications with 15 (4.5%) major complications that required reoperation. We also review the advantages and the procedures for implanting the penile prosthesis on an outpatient basis or a one-day hospital stay.

We herein review the last 29 patients with priapism treated at our hospitals with respect to the physiology and pathophysiology of erection and priapism, respectively, and present a rational approach to the management of priapism. Emphasis is given to the corpus cavernosum to corpus spongiosum shunt with a vascular anastomosis technique.
