Should I stop doing Bikram yoga if trying to get pregnant?

Stick to regular. Bikram yoga ("hot" yoga) is a system of yoga that is classically done in rooms heated to 105 degrees f and run for 90 minutes. This degree of hyperthermia is clearly bad for male fertility, but should probably be avoided for women as well. Regular yoga with ample stretching in a normal temperature environment will decrease chances of dehydration and will still give benefits of traditional yoga.
