Abstract

Spermatozoa were collected by microaspiration from the corpus epididymidis of a 42-year-old man with secondary obstructive azoospermia and used for in vitro fertilization. At insemination 61% of the spermatozoa were motile, with a motility index of 157. One of five eggs was fertilized and this was subsequently transferred to the patient's wife at the two-cell stage. Ultrasound examination and changing hormone levels confirmed an ongoing pregnancy, which is currently at 30 weeks of gestation. This technique will provide a useful alternative for the management of some infertile men with obstructive azoospermia.
