[edit]anyone have a image of what this sheath might look like?
The "sheath" is in fact the remains when of the amniotic sac. It is a very thin membrane, pale and whiteish. The remains of the twin may have disintegrated completely, leaving just an empty sac, or if the bones have started to form ( (ie. after about 12 weeks of gestation) it contains the mummified body of the twin, called the fetus papyraceous, or "paper fetus".

Defunct Sources in Article & Non-Heterosexual Orientation???
[edit]The current article uses published but erroneous sources (Boklage 2006). The Boklage article cites absolutely garbage research papers from the Indian Academy of Sciences. One of which is the (improperly cited) source for the idea that twin survival is explanatory for homosexuality, which is a hilarious article (Klar 2004, J Genetics). The methods say the author was on a gay beach and came back to look at their hair whorl direction, like come on. Later research (Rahman 2009) does an actual study and finds no relationship between hair whorl and sexuality. The article seriously needs to be rewritten. — Preceding unsigned comment added by Frankendubs (talk • contribs) 14:12, 22 October 2024 (UTC)
- I've independently encountered the same articles, and I am going to remove the mention of "non-heterosexual sexuality" in the article. There's no reason to keep clearly debunked information in there.

Consequences to the psyche of a survivor
[edit]I think this section could really do with some more references and alternative theories. I know that this is a fairly contested subject within psychology, but only one opinion is presented here.
I also think the section needs to be rewritten to match wikipedia standards, it appears to be written by someone trying to plug their website. The information within that section also appears highly dubious.
In fiction.
[edit]the Stephen King book "The Dark Half" is a fictitious development directly based on this very real medical phenomenon. 103.12.191.32 (talk) 06:21, 22 September 2024 (UTC)
Historical detection during teenage years.
[edit]I have no reference for this, but I have read in more than one place (and yes I realize that this is hardly "authoritative" LOL) that back before there were X-rays and CT scans and Ultrasounds, that often teenagers as they went through puberty and the teenage growth spurt would suddenly develop various "strange" symptoms, which would eventually resolve to be evidence of an absorbed twin. The two examples that I read were:
Teenagers having unexplained headaches is a fairly normal phenomenon. Such headaches normally fade with time. However, if they didn't, but instead got worse and worse, often the headaches would be bad enough to warrant exploratory skull surgery. Such surgery would find - somewhat alarmingly at the time, remembering we are talking about a long time ago - "inappropriate" bone fragments (ie, fragments of a type of bone clearly not belonging to the skull), or perhaps some teeth.
The other one was that teeth or bone fragments would slowly "emerge" through the skin, having been "pushed out" by the normal asymmetric teenage growth. 2001:8003:E40F:9601:741D:63C3:A05A:37D9 (talk) 08:37, 23 September 2024 (UTC)
