According to wiki the men have won the conference tourney 9 times in the following years:
1990, 1996*, 1998*, 1999*, 2002*, 2004, 2011*, 2016* (Am), 2024*
And they have won the regular season 11 times in:
1990*, 1994*, 1995*, 1996*, 1998*, 1999*, 2002*, 2003*, 2005, 2006, 2024*
And every year the men won one or other the women did too so the total is 14 if you count either reg or tourney titles. (7 tourney title sweeps and 9 regular season sweeps.)
1990*, 1994*, 1995*, 1996*, 1998*, 1999*, 2002*, 2003*, 2004*, 2005*, 2006*, 2011*, 2016*, 2024*
The * represent women's championships corresponding to the men's - two stars mean both reg and tourney, one means only one. The women won the regular season every year the men did except for 2005 and 2006, and the tourney every time except 1990 and 2004. They have combined for five sweeps of all four in 1996, 1998, 1999, 2002, 2024
NB Didn't included men's Yankee conference titles as they date back to pre - women's team days and ECAC tournament wins date to the dark days of the early women's team (1976, 1979)
On Edit: ** seems to change to * and italics when posted so changed to BLUE for women's doubles
