While all this raises some interesting questions, the assertion that he had born a hormonal treatment robbing him of his sexual desires, and playing havoc with his body’s hormone balance “with good humour” seems ludicrous. In fact, the treatment was more likely a serious burden, both physically and emotionally. And if Turing acted cheerful in spite of that this suggests he was hiding his real emotions under a mask.
Hear hear. It's a dismissive and flippant assertion of the kind made by a people who deservedly feel guilty. The "chemical castration" was an option created by people who were clearly willing to do worse. No doubt the behavior of the Cambridge Five created a climate justifying suspicion by "the type so inclined".
