The young mans thighs and abdomen would be tied and others would pin him down on a table. The genitals would be washed with pepper water and then cut off.

In other cases they might be paid to become eunuchs. They served in many capacities, from supervising public works, to investigating crimes, to reading public proclamations. Thailand
In Siam (modern Thailand) Indian Muslims from the Coromandel Coast served as eunuchs in the Thai palace and court. The Thai at times asked eunuchs from China to visit the court in Thailand and advise them on court ritual since they held them in high regard. Burma

For several centuries, Muslim Eunuchs were tasked with honored roles in Medina and Mecca. They are thought to have been instituted in their role there by Salah ad-Deen Ayubi, but perhaps earlier. Their tasks included caring for the Prophet Muhammad’s tomb, maintaining borders between males and females where needed, and keeping order in the sacred spaces. They were highly respected in their time and remained there throughout the Ottoman Empire’s control of the area and afterward. In the present day, it is reported that only a few remain.
Coptic involvement
In the 14th century, the Muslim Egyptian religious scholar Taj-al-Din Abu Nasr Abdal-Wahhab al-Subki discussed eunuchs in his book Kitab Muid al-Niam wa Mubid al-Niqam (Arabic: كتاب معيد النعم ومبيد النقم), a title that has been translated as Book of the Guide to [Divine] Benefits and Averting of [Divine] Vengeance and also as Book of Tutor of Graces and Annihilator of Misfortunes. In a chapter dedicated to eunuchs, Al-Subki made "the clear implication that eunuchness is itself an office," Shaun Marmon explained, adding that al-Subki had specified occupational subgroups for the tawashiya [eunuchs]: the zimam watched over women, and the muqaddam al-mamalik over adolescent boys.Edmund Andrews of Northwestern University, in an 1898 article called "Oriental Eunuchs" in the American Journal of Medicine, refers to Coptic priests in "Abou Gerhè in Upper Egypt" castrating slave boys. Coptic castration of slaves was discussed by Peter Charles Remondino, in his book History of Circumcision from the Earliest Times to the Present, published in 1900. He refers to the "Abou-Gerghè" monastery in a place he calls "Mount Ghebel-Eter". He adds details not mentioned by Andrews such as the insertion of bamboo into the victim. Bamboo was used with Chinese eunuchs.
