Intromittent organ:
An intromittent organ is a general term for an external organ of a male organism that is specialized to deliver sperm during copulation. Intromittent organs are found most often in terrestrial species, as most aquatic species fertilize their eggs externally, although there are exceptions. For many species in the animal kingdom, characteristic of internal fertilization. [Wikipedia]
There might be a word missing there, although I’m not sure what it might be. I ran across this word/phrase on Greg Fallis’ blog:
To some Doctor Who fans, however, there is one immutable characteristic of the Doctor. One physical facet of the Doctor’s being than is indispensable, regardless of the regeneration process. One supreme, conclusive physical attribute that defines the Doctor. An extendable intromittent organ that acts as a sperm delivery system. To these fans, the Doctor’s physical body is apparently nothing more than an extension of the Doctor’s dick. Absent that organ, the Doctor is a sham.
In other words — no dick, no Doctor.
