Mogen clamp


Mogen clamp

The Mogen clamp, one of the three most common circumcision devices, was invented by Rabbi Harry Bronstein in 1954.[1] It has two flat blades that open approximately 3 mm.[2] The name "Mogen clamp" is a general term for a style of clamp; there are several different manufacturers of specific models.

History and prevalence

Rabbi Harry Bronstein, a mohel from Brooklyn, invented the Mogen clamp in 1954. The name "Mogen" was derived from the Hebrew word מגן (magen), which means shield. Bronstein hoped to standardize circumcision equipment for mohels and doctors.[1] Medical literature reports that the Mogen clamp is (probably) the third most popular circumcision clamp (after Plastibell and Gomco) used by medical practitioners in hospitals.[3]


The hospital circumcision procedure with the Mogen clamp is as follows:

  1. Apply local anesthetic
  2. Use hemostats to draw the foreskin forward
  3. Break any adhesions from the foreskin to the glans penis
  4. Place the Mogen clamp over the foreskin following the angle of the corona, ensuring the glans is not trapped
  5. Use the Mogen clamp arm to close the clamp, crushing the foreskin along a line that is 1mm wide
  6. Excise the foreskin distal to the clamp
  7. Release the clamp arm and remove the clamp
  8. Liberate the glans by pulling the crush line apart
  9. Bandage[4][5]

The hospital procedure usually takes three to four minutes and is virtually bloodless.[5]

Newborn post-procedure care

  • Remove the bandage 48 hours after the procedure
  • Clean the penis by washing gently with water several times per day[6]


  • Fastest:[3] Procedure with Mogen clamp has been found to be from 2.5 times[7] to over ten times[8] faster than with Gomco clamp and almost two times faster than with the PlastiBell technique[9]
  • Preferred by hospital residents and interns vs. PlastiBell in one institution in San Francisco [9]
  • Does not leave a foreign body at the circumcision site vs. Plastibell [5]
  • Least likely to lead to infection[10]
  • Allows full visualization of exactly how much foreskin to remove[3]


  • It is not possible to remove as much inner foreskin as with the Gomco clamp
  • Scar might be crooked if the device isn't perfectly angled and lined up
  • Device does not directly protect the glans during the procedure[5]
  • The glans is not visualized before removal of the foreskin[3]

Complications specific to the Mogen clamp

A 1984 study of 313 circumcisions using the Mogen clamp states "Circumcision using the Mogen clamp is a simple quick, and safe procedure." The study showed that the "complication rate was low (1.6%)."[11]

If the Mogen clamp is placed inappropriately,[12] or is otherwise used in a way outside the manufacturer's specifications,[13] injury to or removal of a portion of the glans penis is possible; several cases of this occurring have been reported.[3][12][14]


A Massachusetts lawsuit regarding a circumcision performed using Mogen Circumcision Instruments' clamp resulted in a $7.5 million judgement against Mogen Circumcision Instruments of New York in 2007. This judgment caused Mogen to go into default.[15]

In a case in which 85% of a child's glans penis was accidentally amputated, and could not be reattached, a lawsuit was filed against Miltex Inc., Miltex Inc.'s parent company Integra Life Sciences Holding Corp., and the doctor who performed the circumcision. Miltex Inc. and Integra Life Sciences Holding Corp. were ordered to pay the child and his mother $4.6 million. The lawsuit against the doctor was dismissed.[1][16][17]
