Do trans men experience menopause, or does it happen artificially if someone is taking testosterone?
"Trans men" are women (= adult human females) so it doesn't really matter, does it?
... but yeah, they would go through some weird changes if/when their female hormones get switched off. Taking male hormones on top would alleviate some symptoms, but not all. You can't change sex, but you can mess up your body by trying to do so.
When it comes to biology/medicine, made up social categories and gender feelings aren't particularly relevant. The only definition of man/woman that makes sense in that context is the male/female sex binary.
