hi shijiaxin, 2 yrs ago my husband was diagnosed with teratozoospermia and it was a big setback for us. What we did was we went round consulting chinese physicians to build up good health. As I was about to give IUI a try with my gynae, suprisingly I got pregnant. Despite the diagnosis, I gave birth to a healthy baby boy on Sep 2010. So dont give up yet and keep trying.... Good luck to you!
