LillyM he recommends it for everyone. We did 5 cycles with Wazza in 6 months and found that we got much better results on the last cycle, so we'd both been on supplements and DH had been icing for 6 months. Some of the supplements take 4-6 months to really take effect (Co-Q10 and DHEA I think). DH continued to ice through until heartbeat was detected and wore boxers until we reached the end of the first trimester. We also used PICSI for the last 4 cycles and that improved fert rate and number/quality of day 5 embryos significantly.
