Summary. The data from 636 patient cycles from an outpatient‐based in‐vitro fertilization and embryo transfer programme are presented. Between 1984 and 1988, 545 women (86%) underwent ultrasound directed follicle aspiration (UDFA) exclusively by the perurethral route. The mean follicle aspiration rate was 93%, and the mean number of oocytes per procedure was 5.8. The complication rate was 6%, but none was major. From July 1985 the clinical pregnancy rate per UDFA was 17% and per embryo transfer 21%. The perurethral approach was used in combination with another UDFA route in 91 women (14%) but the need to change route decreased with increasing operator experience. Perurethral UDFA is an efficient and safe method for harvesting oocytes.
