[Pregnancy by micromanipulation in a case of excretory azoospermia associated with a natural spermatocele].
Microinjection of capacitated sperm into the perivitelline space of oocytes has been performed in a case of male infertility attributed to excretory azoospermia. In this particular case, a spermatocele detected five years ago was observed, which provide motile spermatozoa. These sperm collected by direct puncture into the cyst, were capacitated using discontinuous Percoll gradient. After ovarian stimulation, seventeen oocytes were collected. Nine of them were used for classical IVF whereas the other eight were submitted to microinjection. Only one oocyte of the second group fertilized and cleaved 48 hours later. A clinical pregnancy was achieved after embryo transfer and a normal, healthy boy delivered at term.
