Improvement of follicular puncture and oocyte recovery at Erlangen.
The instruments for oocyte collection for IVF developed at Erlangen as a result of experience over a period of two years are described in detail. In a consecutive series of 30 IVF attempts (30 patients), 77 oocytes were collected from 78 follicles. The advantages of our very simple and successful system are discussed, and compared to other systems. Embryo transfer was performed in the 21 patients and four progressive pregnancies resulted.
