- Well, lets put it this way: less than 10% of medline abstracts on etiology of
- endometriosis mention retrograde menstruation at all. About 1/2 of those that
- do mention it say it has no effect; 1/4 of them say there's no evidence that it
- ever happens at all; & 3 claim that it is universal in all menstruating women.
- One article (out of a couple hundred) *speculates* that "since retrograde
- menstruation is universal" (no evidence provided) and an increase in total
- number of lifetime menstruations is positively correlated with an increase in
- incidence of endometriosis (this has been statistically demonstrated), that
- *maybe* retrograde menstruation *might* deposit sloughed endometrial cells in
- the peritoneal cavity which then implant, causing endometriosis.
-
- Not exactly what I'd call strong evidence.
-
- Exasperatingly <grrrr> there's more research into whether having a job causes
- endometriosis than there is on whether IUDs or cervical caps cause or
- exacerbate it. Oops; I'd better hit SEND before I get myself started.....
