Hot yoga (vinyasa)

Hey I wondered if any of you have had successful pregnancies while attending  heated yoga classes (90 degrres F). I'm trying to concieve now & have been doing heated yoga classes for awhile now but wondered if the heat might effect the sperm while ttc inside of me (as I'm ovulating) I just really get a lot of mental benefits and it helps to destress me when I do yoga so I don't wanna quit but I will, if it's not so good in that department ! Anybody know?
