Thanks for the replies. We have already gone through 2 unsuccessful ivf/icsi procedures and 4 fet, with 1 chemical pregnancy which was lost at 2 weeks, the drs blamed it on the low quality of the embryos from bad/ unhealthy sperm. We decided to do the surgery for my husband now as it takes 3-6 months to see results, and not to do aything in the meantime. We opted for the angioplasty option and were hoping they could get to the vericoceles on both the right and left sides. They were able to fix the large vericocele on the left, but also, bc of anatomical structures, weren't able to pass into the right vein they needed. The dr advised us to wait and see what if any results we get, and only then consider going for the actually surgery, I dont think we will, even if we dont get good results. Just a few words for people considering doing the angioplasty procedure- it is long, and your dh is left awake during the whole procedure, my husband said he could feel the catheter moving in his body, and at some points he felt a lot of pressure and some discomfort. The dr said this is very rare. He was told he could resume activities of all sorts the next day, but dh was sore and he had a lot of discomfort around the area where the stint and chemicals had been inserted. Whats amazing about the surgery, is immediately after, the vericocele collapses, and if, like us, there had been a high grade vericocele, you couldnt feel it anymore1 We are hoping that it will help at least some of the sperm parameters and will keep everyone posted in a few months when we go back to check results. Thanks for all the info!
