Please explain. The DSM does not state this.
Please explain how that's propaganda. I must admit that I haven't yet read all the 34 studies there, but the method of the summary at least is pretty sound.
1. Sets aside suicide rate as not as important.
2. Meta analysis. Notoriously prone to some fairly obvious bias.
3. 12 of the 34 (33) studies employ populations that won't produce a statistically significant result in MtF, FtM, or both groups. You can't simply add all these populations together, or take an average. That's sloppy science.

4. "Summary" conclusions noted only state some improvement in quality-of-life, with failure to set any kind of baseline mental health.
5. Detailed Results include unsourced criticism of data that doesn't agree with findings, indicating yet more confirmation bias.
The bottom line is, meta analysis is extremely dodgy at best, and scientifically invalid at worst. The author, Greta Una is not a scientist or even skilled researcher, and exhibits many hallmarks of confirmation bias. I wouldn't necessarily say that a transsexual person doing the search is invalidated, but given the other prejudices exhibited, it may be indicated here.
The first of them is actually covered in that "propaganda" summary I linked (as one of 3 studies that show a decline in quality of life - as opposed to 26 studies that show an improvement).
The second one is not available for free (and was published after the summary), but the abstract doesn't mention that it would be about changes before and after transition.
The third one (also published after the summary) is 302 pages long - it would have been nice if you would point me to where it covers our question. I looked through it but didn't find anything on it.
You don't like actual scientific explanation, fine. But I wish you'd say so, rather than just dismiss it out of hand.
