TAILIEUCHUNG - Oocyte Retrieval

Laparoscopy Before the era of clinical in vitro fertilization (IVF), oocytes were acquired by laparotomy (1). Aside from the escalating scientific interest in fertilizing and culturing human oocytes in vitro, the development of laparoscopic surgery also facilitated the use of IVF in treatment of infertile couples. At the end of 1960, the laparoscopic technique made it possible to retrieve human oocytes quite simply for both research and clinical purposes. The technique played a key role in the start of collaboration between Edwards, the scientist with the knowledge of how to fertilize and culture human oocytes in vitro, and Steptoe,. | 7 Oocyte Retrieval Matts Wikland Department of Obstetrics and Gynecology University of Gothenburg and Fertility Centre Scandinavia Gothenburg Sweden INTRODUCTION Laparoscopy Before the era of clinical in vitro fertilization IVF oocytes were acquired by laparotomy 1 . Aside from the escalating scientific interest in fertilizing and culturing human oocytes in vitro the development of laparoscopic surgery also facilitated the use of IVF in treatment of infertile couples. At the end of 1960 the laparoscopic technique made it possible to retrieve human oocytes quite simply for both research and clinical purposes. The technique played a key role in the start of collaboration between Edwards the scientist with the knowledge of how to fertilize and culture human oocytes in vitro and Steptoe a clinician mastering a technique that could be used to harvest oocytes in women with tubal infertility 2 . Subsequently laparoscopy became the technique of choice for oocyte aspiration during the first 10 years of this clinical IVF era. Different technical aspects surrounding this technique were published at that time by those groups involved in the early clinical practice of IVF 3-5 . Retrieving oocytes under the guidance of a laparoscope was a fairly simple technique with a high oocyte recovery rate. However general anesthesia was routinely needed and only in certain patients was it performed with local anesthesia 6 . Furthermore laparoscopy exposes healthy women to risks that are not negligible and it is rather an expensive method. In order for IVF to evolve into a procedure that could 117 118 Wikland be afforded by many women there was a need to find a technique for oocyte retrieval that could be performed as an outpatient surgical procedure. Even in those cases when laparoscopy was performed using local anesthesia it was still quite a technically demanding technique using expensive instruments and unsuitable to performing .
