My sister and her dh have been ttc and they finally sent dh for a sperm test. He had no sperm at all. The specialist says there is a blockage. He is scheduled for an extraction and then a surgery to repair the problem They want to try AI with his sperm ASAP because the DR. said the surgery won't likely be successful for about 3 years!?! They have also been told they should try IVF. My sister has been charting her cycles for a year. She is in perfect health and is ovulating etc etc. Why would they need to use IVF??<img alt="" class="inlineimg" src="http://www.mothering.com/discussions/images/smilies/confused.gif" style="border:0px solid;" title="Confused">:
