Allow me to put on pediatrician hat - actually its the goofy tie that does it - ah there …
There is really no particular good medical reason to get or to not get a baby circumcised. The benefits are real but very small and the risks are real and also very small. Pretty much a wash. My boys were circumcised as a matter of religious obligation but if not for that we would have opted out as my personal basic belief is that the burden of proof of benefit is on the doing rather than on the not doing. Even for a minor surgical procedure like this one.
The AIDS risk reduction is real and possibly significant given the African location albeit discretion and condoms are a much better option.
lee actually one of the small benefits of circumcision is a lower risk of UTIs.
As for effect on sexual function, we actually know very little. In general circ’ed males have a more varied sex life but that might be sociocultural selection bias. And some circ’ed adult males with sexual dysfunction blame their dysfunction on their circumcision status whereas uncirc’ed adult males with sexual dysfunction have to find something else to blame. Studies of adult males circumcised as adults for medical reasons show no consistent pattern other than lasting a bit longer.
