No need to send posts directly to me as well as to CSGnet, Jim. I get
two copies when you do that, and waste Net bandwidth. Anyway, welcome to
the discussion.

Thus, one may want to look at menstrual synchony from a different
perspective, in that it also correlates with ovulatory sychrony.
I understood Jeff Vancouver's question to relate to why where is
sychrony at all. Ovulation is simply part of the menstrual cycle, isn't
it? If anything in this cycle correlates with something else, then all
events in the cycle would correlate with it. But why should one woman's
menstrual cycle be synchronized with another's? And how would that work?
The next comment is triggered by your comment but isn't aimed
particularly at you. In PCT we try to work with data that show phenomena
clearly and that don't carry a lot of negative instances of a proposed
explanation along the positive ones. When studies are reported in
CSGnet, I for one would like to see certain facts reported along with
the results:
1. How many individuals were studied?
2. How many showed the effect that is reported?
3. How many did NOT show the effect that is reported?
It seems to me that any theory has to explain any more-than-negligible
numbers under item 3.
You cite this result:
Jutte (1995) has shown that women's ovulatory pheromones induce a
testosterone response in men.
It would be helpful to me in evaluating this result to know how many
man-woman pairs were studied, how many men showed the testosterone
response, and how many men did not show it. And I would be interested in
any explanation that was offered for the men who did not show it.
