In vitro fertilization and birth after ultrasonically guided transurethral aspiration of oocytes.

We have described an in vitro fertilization and embryo transfer accomplished by ultrasonically guided transurethral transvesical oocyte aspiration. Follicular aspiration using ultrasonography is a suitable alternative to traditional laparoscopic methods, and may have several advantages, including avoidance of surgical and general anesthesia complications. Further experience with this technique will clarify the benefits and/or risks, and this work is continuing.
