I doubt it affects attendance much. I've noticed in past years that women's ice hockey games at UConn usually have only a couple hundred people attending no matter if the men's team is playing at the same time or not.
Part of the schedule conflict is due to the weekends being prime time for playing all college hockey games for both sexes. Part of this is also due to the limited availability of the XL Center to the men's ice hockey team, which seems to be the reason that the men's team often plays on Saturday afternoon, which is usually a prime time for women's games. But obviously, if the two teams were playing in the same arena there wouldn't be any conflicts.
When both teams were playing on campus, the tendency was for the men to play on Friday and Saturday nights, while the women play Saturday and Sunday afternoons. When the men didn't have a home game on Friday night, one of the women's games would occasionally slide over into Friday night. Generally speaking, night games are more desirable in college hockey, so it is no real surprise that with the men no longer playing on campus, the UConn women want to play more Friday night games. This would have the advantage of avoiding Saturday or Sunday conflicts with either of the UConn basketball teams, which would be an especially important consideration if either of these teams are playing on campus at Gampel.
