Does circumcising an HIV-positive man increase his risk to transmit HIV?

[return to first circumcision page]

Best evidence: Yes, circumcised men seem to transmit HIV faster

This answer comes from the one trial which looked at the issue.[1] During 2003-7, researchers in Uganda ran a study to “test whether male circumcision would reduce transmission of HIV…to their uninfected female sex partners.” The study recruited HIV-positive intact men and their HIV-negative partners (wives, steady partners), then on a random basis circumcised some men but not others, and then followed all partners, testing women from time-to-time to see who got HIV (to be sure a woman’s HIV came from her man, the study confirmed that a couple’s HIV were similar).

The study found circumcised men were 1.58 times more likely to transmit compared to intact men: 18% (17 of 92) of  women with circumcised partners got HIV compared to only 12% (8 of 67) of women with intact partners.[1] But because the trial saw only 25 new infections, there was a 28% chance this result was a statistical accident due to chance only.

Notably, the relative risk for women with a circumcised man increased over time: during the first 6 months partners of circumcised vs intact men were 1.46 times more likely to get HIV; from 6-12 months, they were 1.52 times more likely to get HIV; from 12 to 24 months, they were 2.3 times more likely to get HIV. (However, these statistics are unreliable because of small numbers of infections.)

But the study was stopped early…

By design, the trial was supposed to follow all women for two years; in other words: “the female acquisition end point cannot be determined prior to the completion of the trial.” [p 38 in reference 2]. This trial design makes sense, because once men are circumcised to see what happens to women’s HIV risk, men’s foreskin cannot be reattached.

Despite the plan to follow women for two years, the research team stopped the trial early. The excuse was that the study was unlikely to show circumcising an HIV-positive reduced the risk he would infect his partner.

Here’s what Jim Thornton (former editor, British Journal of Obstetrics and Gynaecology) says about stopping the trial early[3]: “Consider a treatment which affects husbands and wives. Treating one automatically treats the other. Evidence accumulates that it is good for the husband but results are unclear for the wife. It would be bonkers to stop when interim data showed a non-significant harmful trend for wives, on the grounds that the treatment was never going to be good for them, and then go ahead and implement it!   But that’s what the authors of the only trial ever to test the effect of male circumcision on HIV transmission to the woman did…”.

The trial was unethical (and illegal?)

The trial was unethical by design: Researchers recruited HIV-positive men even if they were not willing to learn their HIV status and to warn their partner. “[A]bout a quarter” of HIV-positive men did not tell their partners they were HIV-positive.[1]

Following women at risk without warning them is unethical. It may have been illegal as well. According to Ugandan law, “any person who unlawfully or negligently does any act…which he or she knows or has reason to believe to be likely to spread the infection of any disease dangerous to life commits an offence and is liable to imprisonment for seven years.”[4]

Researchers (and UNAIDS) disregard women’s risk to get HIV from circumcised men

The research team recommended “…circumcision for remaining HIV+…men who had completed their 2 year follow-up…”[5] Compounding the damage, researchers did not insist on couple counseling before circ’ing HIV-positive men, even though many women were not aware their partners had HIV.

Similarly, the research team recommended circ’ing men in Africa whether they are HIV-positive or not, and without insisting on prior HIV tests and couple counseling. UNAIDS offers the same anti-women advice: “The offer of male circumcision should neither depend on a person undergoing an HIV test, nor on a person being…HIV-negative.”[6]

Don’t forget women’s non-sexual risks for HIV!

There’s a lot of evidence that much if not most HIV among women in Africa comes from healthcare and other bloodborne risks. For example:

  • A survey among students 5 high schools in Umgungundlovu District of KwaZulu-Natal found 135 HIV-positive girls of which 77 (35%) reported they were virgins.[7]
  • 15 studies of new HIV infections in pregnant and early postpartum women in Africa report women getting new infections at rates from 6.1% to 19% per year;[8] these rates are higher — many are much higher — than could be expected from sex.

    Can a circumcised man transmit HIV virus after 3 years of circumcision?

      Hi Socks,
      Thanks for your question. The answer is: Yes.
      Even after the circumcision wound heals, a circumcised man who is HIV-positive transmits HIV through sex about as easily as an intact (uncircumcised) man.

    Can a newly circumcised HIV negative man transit virus if he resume sex during healing period.

    • Anonymous June 29, 2018 at 9:34 pm

      Some confusion here? If the man is HIV-negative, he can’t transmit whether he is circ’ed or intact. If he’s HIV-positive, he could infect his sex partner if the wound has not healed, and he may have an increased risk to transmit even after the wound has healed.
