I was watching a StarTrek episode the other day (the original with Kirk, Spock, McCoy, Sulu, Chekov and Scott), and began wondering. In the world of intergalactic interaction(ii), there are males of several planetorial and galaxial backgrounds. Were they like Earthlings and of long histories which included both pros and cons towards circumcision? Did they have various religious sects which either praised and requested circumcision or forbade it under risk of excommunication from the religion? Research, found that Vulcans in particular are left untouched, although the reasoning may be disturbing to many. Introduction To Vulcan Physiology - Star Trek Online Geekipedia The Vulcan male reproductive organs parallel those of most other known humanoid/vulcanoid beings. The Vulcan penis is an erectile structure without external sheath or foreskin, therefore Vulcans have no need for circumcision. As part of the evolutionary process of T'Khasi life, the male organ is almost fully retracted into the body when not in use as a protective measure. Vulcans also have two testes in a scrotal structure that is close to the body, not pendulous, and a prostatic body that produces and stores seminal fluid. Once ejaculated, the sperm of Vulcans is viable for a maximum of about 30 hours before losing mobility. It is believed that Vulcan males remain fertile during their entire adult life. Yes, there we have it, Vulcans are without skin. How about the Klingon or the Ferengi or the Cardassian? It can be presumed that given their similarity, the Romulans are like the Vulcans and don't possess skin either. From further reasearch, I found whispers that Klingons are uncircumcised for the most part- which hinted that it may be done as part of retribution upon slaying an enemy (maybe even just capturing an enemy). So, if the Montgomery Scott were captured by Klingons, he might indeed have his foreskin sliced off as part of negotiations between Starfleet and the Klingons. I wonder how they'd handle it if they captured Spock; though, since he is half human (his mother), perhaps he has an always external penis and was born with a foreskin, if so, was he circumcised? I am still not sure about Cardassians and Ferengis. Here too, a whisper was found that had a Cardassian quite disgusted when someone mentioned being circumcised. I am also curious as to the foreskin quotient of each group and of the earlier Klingons (Kirk generation) compared to those of later Klingons, who were vastly different in appearance.
