Ultrasonically guided percutaneous and transvaginal follicle aspiration; a comparative study.

In this study we compare the efficacy of ultrasonically guided percutaneous oocyte collection for in-vitro fertilization with ultrasonically guided transvaginal oocyte collection. Forty-seven patients were prospectively randomized into two groups. Twenty-four patients underwent percutaneous follicle aspiration and 23 patients underwent a transvaginal puncture.

Ultrasonically guided percutaneous and laparoscopic oocyte aspiration: a comparative study.

Oocyte collection for in vitro fertilization was performed in 105 cycles (65 patients) by ultrasonically guided percutaneous puncture (63 cycles) or laparoscopy (42 cycles). During the ultrasonically guided approach an open or closed needle system was used. During both ultrasonically guided and laparoscopic follicle aspiration, all visible follicles were punctured.

Ultrasonographic assessment of Graafian follicle growth under monofollicular and multifollicular conditions in clomiphene citrate-stimulated cycles.

Growth of the dominant follicle was assessed by means of real-time sector scanning in 52 clomiphene citrate-stimulated cycles in 44 patients awaiting laparoscopic oocyte recovery for in vitro fertilization purposes. Follicular growth profiles under both monofollicular and multifollicular conditions were compared with each other and with a reference growth curve derived from 26 ovulatory cycles in 25 spontaneously cycling women. In the clomiphene-stimulated cycles, growth of the dominant follicle under both monofollicular and multifollicular conditions was significantly faster (P less than 0.
