Valid point, although I suppose it depends on whether we equate 'anti-androgen' with 'pro-oestrogen' drugs.
It appears that Turing was given anti-androgen drugs (probably cyproterone acetate, which apparently was all the rage in Europe then) in order 'to reduce male sexual interest.'
Interestingly, I found: 'cyproterone acetate suppresses production of oestrogen due to its antigonadotrophic effect.' As both men and women produce oestrogen, this would suggest that whatever the normal oestrogen level in Turing's body, it would have been reduced not augmented.
I did a quick scoot around the net to find out a bit more about judicial chemical castration. In all the references I found, it appears that the clear objective of chemical castration when used as a punishment was to reduce libido in a male convicted of a sexual offence (probably best to leave aside the moral discussion about what constitutes a sexual offence - eg Turing).
Thinking about it, it would seem a pretty pointless exercise to give anti-androgen drugs to a man convicted of a sex crime if all it did was make them grow breasts (unless the embarrassment factor alone is considered to be a deterrent).
