I am researching the subject:
Came across this analysis of 36 studies methodologically good-to-rigorous, examining the impact of circumcision on men's sexuality:
\"The researchers scoured the world medical/sexuality literature and found 36 methodologically good-to-rigorous studies examining the impact of circumcision on men's sexuality. The two best reports met the gold standard of research, placebo-controlled, randomized clinical trials, both in southern Africa, where circumcision has become an extremely cost-effective approach to controlling AIDS.' Researchers in Kenya surveyed the sexual function, pleasure, and satisfaction of 2,784 uncircumcised sexually active adult men. Then they circumcised 1,391 of them, and re-surveyed the entire group every six months for two years. In every survey, the two groups showed no statistically significant differences in sexual function, pleasure, or satisfaction. The researchers also asked the circumcised men additional questions focusing on any differences they noticed before and after the procedure. At the two-year mark, 99.9 percent of the men said they felt 'satisfied with their circumcisions,' and far from decreasing penile sensitivity, 72 percent said their sensitivity had increased. In addition, 78 percent said circumcision made it easier to don condoms.' Researchers in Uganda conducted a similar trial involving 4,456 uncircumcised adult men, 2,210 of whom got circumcised. Before-and-after surveys showed no differences in sexual desire, erection issues, or other measures of sexual function, pleasure, and satisfaction. Two years after the procedure, 99.9 percent of the uncircumcised men said they felt 'satisfied or very satisfied' with their sex lives, while among those who'd been circumcised, the figure was a statistically equivalent 98.4 percent.The other 34 studies showed similar results. \"Source:
