Pituitary gland

I have had unexplained infertility for years. I did a year of different medications, injections, timed intercourse, and <a href="https://glowing.com/glow-fertility-program">iui</a>. Recently I got a head injury and had an mri and it was discovered that my pituitary gland, which controls hormones, is enlarged. Has anyone ever had this problem? Or successfully figured out a way to still conceive with this issue?
