Infrared heat pad

I was wondering what your thoughts are on using one on a low setting to improve circulation and help egg quality ? When I was seeing a traditional Chinese practitioner religiously he recommended using a moxa stick, which is pretty much infrared heat at certain points on my lower stomach. Because I don't like the smell of moxa, I got an infrared heat pad instead and have been using it on my stomach for an hour per night. Anyone know if this is helpful/not helpful before ivf ? I couldn't really find any research on it. I am due to start stimming in 2 weeks.
