I'm just thinking this through again, as there is a logical flaw in
statement. If we take a
​random ​
sample space limited to just overwrites where men are overwriting women or
women are overwriting men, then the ratio of men:women is irrelevant, given
a large sample. Effectively even if men outnumber women by 80% or 90%, the
numbers of overwrites of type "male-female" and "female-male" should be
almost the same in /both directions/. If the figures are not similar, then
other factors are at play than just that there are more men contributing to
the project.

Testing this theory, I went to the English Wikipedia database and checking
over all time, found:

+-------------+----------+
| sex         | count(*) |
+-------------+----------+
| female-male |       63 |
| male-female |      127 |
+-------------+----------+

Checking the all time figures for Commons shows:

+-------------+----------+
| sex         | count(*) |
+-------------+----------+
| female-male |     1309 |
| male-female |     2220 |
+-------------+----------+

​Quickly going to French (far less statistically significant):

+-------------+----------+
| sex         | count(*) |
+-------------+----------+
| female-male |        1 |
| male-female |       12 |
+-------------+----------+

German:​

+-------------+----------+
| sex         | count(*) |
+-------------+----------+
| female-male |        6 |
| male-female |       39 |
+-------------+----------+

The conclusion has to be that women are
​at least /twice/ as likely to have an image overwritten by a man on our
projects than the reverse happing. The numbers are sufficiently large for
it to appear a meaningful result.
