in this article is that the subject took female hormones. I highly doubt
that this comes under the letter of the letter of the law of Lo Silbash
(although, I agree that it would be included in the spirit). Also, mah
dino? Rambam (Hilchos Nashim 2) discusses the various simanim, if these
are all surgically or chemically induced does it halachically change one's
gender? And, Lu Y'tzu'yer that Surgeons manage to have a (?former?) man
give birth - do we say Banim harey hein k'simanim? Comments?>>

Believe it or not, but there are actually pre20th century meqorot dealing
with that. The matter is in dispute. Interestingly, the Tyity Eli-eyer,
who quotes the older material on the matter, concludes that gender change
is halakhicallz valid. Others disagree. Sources in a pdf provided upon
request. (I gave a shi'ur on this before last Purim)
