Question 531828
Here's my try.
You should get another opinion, too
-----------
One of the male players has 7 women he can choose
as a partner, minus his wife = 6
The number of possible pairs is 7*6 
-----------
The other male player is one of the 6 remaining, and
he can choose one of  6 remaining women, minus his wife = 5
The number of possible pairs is 6*5.
-----------
The number of possible matches is 7*6*6*5 = 1260
