3. I do not knowP: no one has asked this q

3. Session Objectives Show that MC is
Effective in preventing HIV infection
Safe
Acceptable in traditionally non circumcising communities
Discuss
Challenges in implementing MC at scale in low resource settings
How MC advocacy, education, counseling, training, and services can be integrated in ongoing HIV prevention programs
The earliest documentary evidence for circumcision is from Egypt. Tomb artwork from the Sixth Dynasty (2345–2181 B.C.) shows circumcised men, and one relief from this period (Ankh Mahor) shows the rite being performed on standing adult males
Genesis (17:11) places the origin of the rite among the Jews in the age of Abraham who lived around 2000 B.C.

4. Male Circumcision Definition
Male Circumcision (MC) is the complete surgical removal of the prepuce (foreskin) covering the head (glans) of the penis
In many countries MC is conducted in the newborn period; in others it is done as a rite of passage to adulthood
WHO and UNAIDS estimate that globally about 30% of males are circumcised. In Africa, nearly 2/3 of men are circumcised.

6. Previously Recognized Benefits of Circumcision
Human Papilloma Virus (HPV)
63% reduction in circumcised men
Cervical cancer in female partners
2.0 – 5.8 times more frequent in women with uncircumcised partners
Urinary tract infections in infants
12 fold increased risk in uncircumcised boys
Syphilis
fold increased risk in uncircumcised men
Chancroid
2.5 fold increased risk in uncircumcised men
Invasive penile cancer in men
22 times more frequent in uncircumcised men
Mostly observational studies : No RCTs

8. MC and HIV Infection: More Evidence
Meta-analysis by Weiss et al shows that MC is associated with 50% lower rate of HIV infection
Quinn demonstrates in Rakai, that partners of HIV positive women who are uncircumcised had an HIV incidence of 6.7/100 py) while partners of circumcised men 0/50 (p = 0.004) (NEJM 2000)
Biologists find that the prepuce contains many Langerhans (HIV target) cells which are easily infected with HIV in vitro
Biological plausibility
Inner mucosa of foreskin is rich in HIV target cells
External foreskin/shaft keratinized and not vulnerable
After circumcision, only vulnerable mucosa is meatus
Foreskin is retracted over shaft during intercourse
Large inner mucosal surface exposure
Micro-tears, especially of frenulum
Intact foreskin associated with infections
Genital ulcer disease
Balanitis/phimosis
Possible increased HIV entry or shedding

9. Male Circumcision: Best Evidence
Randomized controlled trials are the gold standard in health research
10,000 uncircumcised, HIV-negative men enrolled
Intervention group underwent MC in clinical setting
Control group “delayed” MC for 24 months, or end of the trial
All participants received extensive counseling on HIV prevention, risk reduction and condoms
Auvert et al, PloS med 2005, Gray et al, Lancet 2007, Bailey et al, Lancet 2007,

10. Clinical Trial Results
All three clinical trials stopped early due to efficacy
MC was so protective that it was unethical to continue to withhold it from the control group
MC reduced female to male HIV transmission by approximately 60%

11. Male Circumcision for HIV Prevention
Depending on HIV prevalence in the area, we need to do 5 to15 MCs procedures to prevent 1 new HIV infection (numbers needed to treat)
MC is not only cost-effective, it is actually cost-saving given the high costs of ART
NNT for Measles vaccine is about 120, For AMTSL to prevent PPH/severe PPH 16/100
Male circumcision protects men from HIV infection

12. Adverse Events Hemorrhage, hematoma, infection, severe pain, dysuria
Kenya trial: 21 events (1.5%)
Uganda trial: 84 events (3.6%)
Zambia: MC services: 3.6%
Male circumcision provided in health settings is safe

13. Effect of MC on Male to Female Transmission
Discordant couple study from Rakai, Uganda: circumcised men 30% less likely to transmit to female partners
Clinical trial of MC for HIV+ men found that recently circumcised HIV+ men may be more likely to transmit to female partners
Take home messages:
MC should be targeted to HIV-negative men
If HIV+ men request MC, they must be STRONGLY counseled to abstain from sex for at least 6 weeks / until wound is fully healed
Benefit for women partners of HIV positive men
who have MC still controversial

14. Acceptability Studies in Non-Circumcising Communities (9 countries)
Male circumcision is
Universally perceived to improve hygiene
Widely thought to reduce risk of STI
thought to reduces risk of HIV by some
Biggest barriers to MC are cost, and concerns about safety (risk of infection or mutilation), and pain
Most communities want safe, affordable MC services to be available.

17. % of Participants Who Would Choose to Circumcise a Male Child, if Offered in a Safe Hospital Setting, Free of Charge: Botswana (data shown only for responses following informational session) %
Background: Male circumcision is known to reduce the risk of acquiring HIV, but few studies have been performed to assess its acceptability among either children or adults in sub-Saharan Africa. Methods: We conducted a cross-sectional survey in nine geographically representative locations in Botswana to determine the acceptability of male circumcision in the country, as well as the preferred age and setting for male circumcision. Interviews were conducted using standardized questionnaires both before and after an informational session outlining the risks and benefits of male circumcision. Results: Among 605 persons surveyed, the median age was 29 years (range 18 – 74 years), 52% were male, and > 15 tribal groups were represented. Before the informational session, 408 (68%) responded that they would definitely or probably circumcise a male child if circumcision was offered free of charge in a hospital setting; this number increased to 542 (89%) after the informational session. Among 238 uncircumcised men, 145 (61%) stated that they would definitely or probably get circumcised themselves if it were offered free of charge in a hospital setting; this increased to 192 (81%) after the informational session. In a multivariate analysis of all participants, persons with children were more likely to favor circumcision than persons without children (Adjusted Odds Ratio 1.8, 95% CI = 1.0, 3.4). Most participants (55%) felt that the ideal age for circumcision is before 6 years, and 90% of participants felt that circumcision should be performed in the hospital setting. Conclusions: We conclude that male circumcision is highly acceptable in Botswana. The option for safe circumcision should be made available to parents in Botswana for their male children. Circumcision might also be an acceptable option for adults and adolescents, if its efficacy as an HIV prevention strategy is supported by clinical trials.

Clear international guidance now available.

19. Results and Lessons Learned
Participants with minimal surgical skills can be trained to competency in short courses
Training more that one provider per site is critical
Adverse events are minimal
Standardized training materials work well
Investment in developing high performing training sites is essential
Early follow up of trainees reinforces training.
All participants with previous surgical experience can become competent in the MC procedure during the course
Participants with little surgical experience need more practice with surgical skills (i.e., suturing)
All participants become competent in counseling and group education skills during the course
Participants are better able to use their new skills if they are trained as a team rather than one provider per facility
groups allow MC “alumni” to stay in touch to share challenges and solutions

20. Frequently Raised Issues: Risk Compensation
Won’t circumcised men believe they are 100% protected and stop using condoms and/or increase their number of sex partners?
Response:
Valid concern
No evidence of risk compensation or disinhibition from the MC trials or post-trial surveillance
valid concern
so far there is no evidence of risk compensation or disinhibition from the MC trials or post-trial surveillance. The Kenya trial suggests that counseling received before and after MC can actually reduce risky behavior. Modeling data suggest that risk compensation would have to be quite significant to undermine the protective effects of MC.

21. Frequently Raised Issues: Women’s Issues
MC does not help women and might even put them at risk if circumcised men refuse condoms or resume sex too early. We should focus on microbicide research and the female condom instead of wasting our energy on something that won’t help women.
Response:
MC scale up will reduce HIV incidence in women as well as men
MC communication should also target women so that they know the importance of abstinence during wound healing
There is no evidence that circumcised men are abandoning condoms
There are important gender issues to address in MC, but MC scale up will reduce HIV incidence in women as well as men. While recently circumcised, HIV+ men who resume sex too early appear to be at high risk to transmit the virus. However, men can only transmit HIV if they are infected, and the target population for MC scale up will be HIV-negative men. MC services should include provider-initiated CT so that men learn their HIV status as well as counseling on the importance of abstinence during wound healing (6 weeks). MC communication efforts should target women so that they also know the importance of abstinence during wound healing. So far there is no evidence that circumcised men are abandoning condoms; if anything data from the trials suggests that circumcised men find it easier to use a condom.

22. Frequently Raised Issues: Surgical Capacity
I would love to implement MC in my country but we have limited surgical capacity with long waiting lists. How can I justify using our scarce surgical resources for non-emergency surgery?
Response:
It will not be easy to reach thousands of young men
Train clinical officers and nurses to provide MC.
“import” volunteer surgeons from other countries.
Train nurse-midwives to provide newborn MC. This will reduce the numbers of adolescents & adults who need MC
This is indeed a major challenge. MC is an investment in the future that will ultimately reduce the burden on healthcare workers as fewer people will need HIV clinical care; in fact, MC is not only cost-effective it is cost-saving. In high prevalence countries as few as 5 to 15 MCs will prevent one HIV infection. That said, it won’t be easy to reach hundreds of thousands of young men. Solutions include task shifting from doctors to clinical officers or nurses and “importing” volunteer surgeons from other countries. If nurse-midwives are taught to provide newborn MC the numbers of adolescents and adults who need MC will eventually decrease. Clinical officers and nurses who have been taught adult MC will be available for other minor surgeries, freeing up doctors and surgeons to work on more complex cases. Ideally, MC can build surgical capacity.

23. Frequently Raised Issues: Traditional Circumcisers
In our country we have many traditional circumcisers. Why can’t we train them to do MC for the non-circumcising communities?
Response:
Most men from non-circumcising communities want medical, not traditional circumcision
Complication rates in traditional circumcision are very high (more than 30%)
Medical circumcision is safer and less painful because local anesthesia is used. Healing time is faster because the wound is sutured
The acceptability studies show that most men from non-circumcising communities want medical, not traditional circumcision. In addition, research in Kenya has found very high (more than 30%) complication rates in traditional circumcision. Medical circumcision is safer and less painful because local anesthesia is used. Healing time is faster because the wound is sutured. WHO, UNAIDS and PEPFAR encourage training of health professionals rather than traditional circumcisers

24. Frequently Raised Issues: Traditional Circumcisers
We want to scale up medical MC in our country but the traditional circumcisers are opposed to it, and they are very powerful in the community.
Response:
Involve the traditional circumcisers in the program to get their input. Encourage traditional circumcisers to do the whole initiation ceremony and all of the education for the initiates but have the MC done by a skilled provider

25. Frequently Raised Issues: Newborn MC
I heard that newborn MC is much easier to perform than adult MC. Can we just train nurse- midwives to do newborn MC and forget about the adults?
Response:
Newborn MC is easier and cheaper than adult MC
Newborn MC is an important investment but won’t have an impact on HIV incidence for about 25 years
Ideally both adult and newborn MC should be scale up simultaneously
It is true that newborn MC is much easier than adult MC. In addition, there are no concerns about sex before wound healing. However, if your country just focuses on newborn MC, you will miss the opportunity to reduce HIV incidence among adults. Newborn MC is an important investment but won’t have an impact on HIV incidence for about 25 years. Ideally both adult and newborn MC should be scale up simultaneously.

26. Frequently Raised Issues: Newborn MC
During antenatal care the nurse-midwife asked me if I wanted to have my child circumcised (if it is a boy). I always thought circumcision was for adolescents. Is it safe to circumcise such a small baby?
Response:
Newborn circumcision is safe for healthy babies if done by a trained health professional
The wound heals much faster than in adolescents or adults
Newborn circumcision is safe for healthy babies if done by a trained health professional. In fact, the wound heals much faster than in adolescents or adults. The nurse midwife will explain how to care for the wound. It is important to follow these instructions and to return if there are any problems. If you decide not to circumcise your son as an infant but want to circumcise him later it is probably best to wait until he is an adolescent. Toddlers and young children usually can not hold still for MC under local anesthesia and there are risks with general anesthesia (putting the child to sleep for surgery).

27. Conclusion
Male circumcision is the most effective HIV prevention strategy we have right now that is not user dependant
User dependant methods such as abstinence, being faithful, and condoms provide additional benefits
