I don’t think it’s unreasonable to suppose that anesthetic use has advanced somewhat in the same time period.

I agree that the rate today is probably higher than the 24% that it was in 1995, but keep in mind that a significant number of doctors practicing medicine today graduated from medical school before ~1980 (including the family doctor who cut me).

something that I’m not sure can be said for the female counterpart.

All of the societies in the world which practice FGC also practice MGC, and they use the same level of medical technology on both sexes.

In this African context, genital cutting (of whatever degree of severity) is most commonly performed around puberty, and is done to boys and girls alike. In most cases, the major social function of the cutting is to mark the transition from childhood to adulthood, and it is typically performed in the context an elaborate ceremony. Increasingly, however, African, Middle Eastern, Indonesian, and Malaysian genital alterations (again, of both boys and girls) are being carried out in hospital settings by trained medical professionals—and on infants as opposed to teenagers—on the model of male circumcision in the United States.
