The number of female physicians is small. However, the proportion of female physicians in Sweden in 2005 was similar to the proportion in our study (internal medicine 31%, surgery 14% and urology 11% female physicians). The medical specialities were selected because of expected experience of treating patients with infections or for perioperative prophylaxis.
