Hello. I'm 41 and my first iui (frozen sperm) didn't work. I'll give it a second chance in two months. I'm on vitamins, folic acid, good eating habits, moderate exercise and I don't have any hormonal problems (just some mild PMS symptoms.) Should I take evening primrose oil and vitex? I don't have any ovarian problems and already took medication for a slightly high prolactine level. Your advice will be highly appreciated. By the way, is there a way to help frozen sperm last longer once the procedure is done? Thank you!!!!
