Why Circumcise?

Circumcision should be a decision of the parents. This decision may be based on religion, culture, ethnicity, medical considerations, or individual choice.

The religions of Islam and Judaism require circumcision. For the special needs of the Jewish circumcision please see the web site pertaining to Brit milah.

  • As for the cultural, ethnic or individual choice for circumcision, these issues should be left to the parents.

  • Medical considerations are numerous:
    1. Cancer of the Penis. This disease, which can be fatal, is non-existent in circumcised males.
    2. Urinary Tract Infections. Urinary tract infections are significantly reduced in the first year of life in circumcised males.
    3. Sexually Transmitted Diseases (STD). The transmission of STDs is significantly reduced when the male partner is circumcised. This includes HIV (AIDS). In the 7th Conference on Retroviruses and Opportunistic Infections, held in Vancouver, beginning January 30, 2000, a study by Calvin Cohen, MD was reported. This study was entitled, Ongoing Transmission: Causes, Cases, and Correlate - Viral Load and Risk of Heterosexual HIV Transmission. In this study, the following was reported: '''Of note, they reported that the risk of male-to-female transmission was the same as female-to-male, both showing about a 12% risk per year. A higher risk was noted in uncircumcised males, with a rate of 16.7%, while there were no seroconversions observed in the circumcised men (probability less than .0001).
    4. Medically Necessary Circumcisions. Approximately 10% of uncircumcised males will require circumcision, later in life, for medical reasons. This will incur greater cost and morbidity than infant circumcision. There are many absolute medical indications for circumcision:- phimosis, paraphimosis, repeated episodes of balanitis and balanoposthitis, hygienic care considerations, painful intercourse due to foreskin problems. Men who become quadriplegic or senile often have problems with urination. These men will require the use of an external aid in order to drain their bladders. Urologists agree that placement of such an external aid or appliance can only be done on a circumcised penis thereby requiring surgery at this late stage in life. Even the uncircumcised senile nursing home resident, who does not need an appliance, still requires the indignities of having a health care aide administer his daily penile hygiene. Late circumcision exposes the patient to risk of morbidity and mortality far greater than in the neonatal period. Obviously, the psychic damage in the young child or man is avoidable when infant circumcision has already been accomplished.

    Booking and Preparing for Non-Ritual Circumcisions

    Please note that I have moved overseas. I plan to spend 3 to 5 months a year in Toronto. When I am in Toronto, I plan to be available to do circumcisions. My schedule will be available on this website as well as on my voicemail message. Messages left outside of published dates will not be answered. If you need to get in touch with me regarding a circumcision performed in the past, send an email to:

    I will next be available for circumcisions from July 17, 2023 to Sept. 1, 2023. Any messages left before July 7, 2023 will not be returned.

    As I no longer have a physical office, I will be doing circumcisions in the home of the baby and family. Remember to only leave messages regarding booking if this website or my voicemail message indicates that I am available.

    The following are instructions for booking and preparing for a non-ritual circumcision:

    1. To book a non-ritual circumcision, please call the circumcision line at 416-635-5012. Then, at the prompt, push “0” and “0” again. Leave a clear message for the booker with your name, phone number and the age of the baby. She will call you back unless you are calling outside the dates of our availability.

    2. The booking person will register the baby in our system. She will send you an email with all the instructions for preparing for the circumcision. That email will also contain a consent form for the circumcision procedure and the recommended ring block anaesthesia. You must read this form, print it, sign it and have it ready to give to us when we arrive.

    3. You will be given the option of applying EMLA cream to assist in pain control. If you wish to use EMLA, you will have to buy it and apply the cream one hour before the scheduled procedure. You should be aware that the tube warns of a rare complication called methemoglobinemia if used in babies under the age of six months. Two Toronto pediatricians published a paper in the New England Journal of Medicine which found the cream to be safe in young babies.

    4. Aftercare instructions will be explained to you, the parents and a written copy will be given to you. Aftercare mainly requires Vaseline and gauze to be applied to the wound at every diaper change for two days.

    5. Circumcision is often done today in hospitals or other clinics using one of several available methods involving various clamps. These can take 5 to 15 minutes. Our procedure uses the “Mogen” clamp. Using this instrument reduces the time to about one minute, thereby, also reducing the baby’s discomfort.

    Post Circumcision Instructions

    1. For two days, each time you change the baby's diaper, wrap a new gauze with vaseline around the penis.

    2. During those two days, you may sponge bathe the baby but do not immerse him in water.

    3. After the two days, you may give him a full bath and you can stop the dressing changes.

    4. If there is every any significant bleeding, don't panic. As will be explained in the office, apply pressure to the base of the shaft and hold while calling me right away any time or day or night at 416-635-5012. If it is after hours, weekends or holidays, listencarefully to the instructions on the answering machine and leave a clear message with your name and PHONE NUMBER. The system will page me and you should get a call back almost right away. If you do not hear from us within 1/2 hour try one more time. If you still don't hear in 1/2 hour then go to emerg. This pertains ONLY to significant bleeding and not to a drop or so.

    5. Watch for signs of infection. You would see a pus-like liquid (not a film) which is runny, yellowish, greenish or clear.It may have a bad odour or be tinged with blood. It only needs to be treated with an ointment. It is normal to have a green or yellow film which is DRY and cannot be rubbed off. If you are not sure, please call.

    6. On day one, if the baby has been fed, changed, burped, picked up, cuddled and had his nap but still will not settle down, you can give him a dose of baby's tylenol or tempra. The dose will vary according to age and weight and can be found on the bottle. If needed, you can repeat this dose once after four to five hours.

    Please feel free to ask me any questions you might have.
