Picture: David. It often happens that when someone has had a limb amputated, they experience feelings in the limb they haven’t got any more – the ‘phantom limb’ phenomenon. The phantoms may be just temporary, a curious by-product of the operation. Sometimes the feelings are partial – where an arm has been removed, for example, patients may feel as though they still had their hand, but attached to the shoulder without any intervening arm. Sometimes the experience is more of a problem, with feelings of intense pain in the amputated part which won’t go away and can’t be treated by normal means.

I therefore winced slightly on learning that as well as phantom limbs, there are phantom penises, experienced by those who have undergone a penectomy (a word which is well worthy of a wince in itself). V.S.Ramachandran, who devised an ingenious way of using mirrors to help people with phantom limb pain, by fooling the brain into briefly believing that the missing limb was back, has now turned his attention to penises, together with P.D. McGeoch. This time the research is not about pain relief, however, but gender identity, where the possession or lack of a penis is clearly highly relevant.
Penectomies, it seems, are performed for two main reasons; to eliminate a malignant cancer, or as part of gender reassignment treatment. Since male-to-female transsexuals typically feel themselves to be ‘a woman in a man’s body’, Ramachandran and McGeoch reasoned that their response to penectomy might well be different from that of other patients. And so it proved: while 58% of men who have undergone penectomy for other reasons reported sensation in a phantom penis afterwards, only 30% of those who had done so as part of gender reassignment had a similar experience. So people who felt that a penis was not part of their true body image were much less likely to experience a phantom penis after removal.

Stranger still, perhaps, 62% of a group of female-to-male transsexuals reported having had phantom penis sensations before any surgery. In many cases the sensations dated back for years: in others, they did not occur until hormone treatment had begun. No non-transsexual women, unsurprisingly, reported the sensation of having a phantom penis (‘even when prompted’ as the researchers say).
Ramachandran and McGeoch conclude that the study backs the view that gender identity feelings are hard-wired into the brain, and in transsexuals may be at odds with actual physical shape. They recognise, however, that there are some potential criticisms of the way the research was done.

One weak point is the risk of confabulation. By asking female-to-male transsexuals whether they had ever had phantom penis sensations, were the researchers discovering a phenomenon, or creating one? Transsexuals often have to struggle for the acceptance of their view of themselves; they have a natural reason to want to assert anything that might strengthen their case. The experience of a phantom penis would clearly be a useful piece of evidence in this context. Since female-to-male transsexuals by definition feel that they ought to have a penis, it may not be much of a leap to say they feel as though they have one, once the possibility is suggested.

To some extent, moreover, male-to-female transsexuals might have been inclined to feel that any report of phantom sensations was letting the side down in some subtle way; suggesting that they or their bodies somehow couldn’t give up the idea of having a penis very readily. Indeed, an old Freudian theory which the researchers pour scorn on, had it that the symptoms of phantom limbs expressed an unconscious desire that the limb was still there, so reasoning along those lines is by no means impossible.

However, the researchers have a number of counterarguments. Perhaps the most striking is that female-to-male transsexuals were often able to report details of the phantom penis and its behaviour, saying that it fell short of their ideal penis, for example. Surely an imagined penis, a wish-fulfilment penis, would be fully satisfactory? Less convincingly, I think, the researchers quote cases where the subjects reported the phantom penis behaving in ways – morning or unprompted erections, for example – which a female subject allegedly would have been unlikely to add to a confabulated account. I suspect the female subjects are likely to have been more aware of this kind of detail than the researchers suppose.

At the end of the day, we seem to have some suggestive evidence, but not a fully convincing case. Ramachandran and McGeoch rightly say that evidence from brain imaging studies would be very useful – notably in establishing whether a pre-operative female-to-male transsexual having a phantom penis experience has similar brain activity to a male having normal penis sensations.

    I think that the 7-11 or so dimensions contribute to the way of thinking. If a 2d person has a hard time perceiving a 3 d person, then we, 3d people have a hardtime deciphering the other dimensions, which can be proven mathematically. So my conclusion? Lack of understanding of the dimensions, leading to phantom penis or phantom arm or whatever big word you want to call it.

    It seems that the phenomenon can be extended to some wearings too and hence we can talk about phantom glasses and phantom hats! Since we, as normal people, cannot know what it is like to have phantom limbs, can we conceive it by a comparison to these cases?

    I can definitely identify with the idea of phantom glasses – I’ve often attempted to push non-existent glasses back up my nose – but I’m not sure whether it helps.

    None of this is particularly surprising once one understands that the phenomenal and the physical worlds are not one and the same. Normally coupled by the senses, they can “come apart”, as in cases of phantoms.

    The question that interests me is whether phantom appendages and imaginary ones are just extremes of a continuum, or are phenomena different in kind. I am inclined to suspect the former, being able to imagine such pecularities as a nose like Pinocchio’s, or perfectly normal vulva (I am a straight male). Ramachandran’s trick for regaining control of phantoms seems to support that, too.

    As a post vaginoplasty transsexual woman, I had no sense of phantom male appendage after surgery or any time after. There was a great sense of body congruity post surgery and what was created surgically felt correct. That was years ago, these days, I don’t even think much of that part of my anatomy. It all feels like what it should have been since birth. In my case, the brain mapping theory appears to hold to some degree. This has also been the same experience of other transsexual women I know who have had the same surgery. There are a number of current theories that point to gender identity as a condition of birth and not influenced by nurture alone.

    Neat post! I don’t know why Google doesn’t make it easier to find this kind of stuff…. Keep it coming though!
