Circumcision Studied in Africa as AIDS Preventive

Now a growing number of clinicians and policy makers in the region are pointing to a simple and possibly potent weapon against new infections: circumcision for men.

Armed with new studies suggesting that male circumcision can reduce the chance of H.I.V. infection in men, and perhaps in women, health workers in two southern African nations are pressing to make circumcisions broadly available to meet what they call a burgeoning demand.

The validity of the approach is still being tested. But in Lusaka, the capital of Zambia, surgeons at the University Teaching Hospital began offering circumcisions for about $3 some 18 months ago and are urging the government to expand the service nationwide. Dr. Kasonde Bowa, a urologist at the hospital, says about 400 patients a month request the procedure — eight times as many as the surgeons can accommodate.
