Hello lovely ladies!  I'm Lisa, my husband Kevin and I have been TTC for a year.  I am facing this whole new world of <a href="https://glowing.com/glow-fertility-program">fertility treatment</a>/questions/concerns that I honestly never expected to have...  I was wondering if some of you have maybe had similar stories, and what you're doing/have done to treat these issues.  I have of course been Googling my thumbs off, but my follow up with my OB/Gyn isn't until the 5th, and I'm struggling.
So here's where we're at:  I have had all my bloodwork done and levels came back normal.  My husbands, however, is not good.  His testosterone is REALLY low (137), with really bad sperm motility (4%), fairly bad morphology, (6%), and normal sperm count.
We are being referred to a urologist and an endocrinologist, to determine possible causes for the issues my husband is facing.  What has me so upset is the extremely low success rate of <a href="https://glowing.com/glow-fertility-program">IUI</a> in cases with such low motility and possible necessity of <a href="https://glowing.com/glow-fertility-program">IVF</a>, which is apparently also not very effective in couples like us.  😔
Is there anyone out there who has dealt with such low motility rates and low testosterone?  Has anything worked for you?
