Found out we have a problem

So, back in October/November, we found out my husband has a zero count (they think this could be due to a double blockage (fingers crossed) if it is a blockage there is a hope that a corrective surgery can rectify it. All my tests so far have been normal (still got to get the blue dye test and ultrasound) we have our first appointment at the <a href="https://glowing.com/glow-fertility-program">IVF</a> clinic on Friday 8th March, starting to get nervous and excited all at the same time.

I was just wondering has anyone else had the same problem and had a successful result from a unblocking surgery?
