We saw Dr. Sherins - He is through Columbia Fertility- but I would imagine anyone (i.e. non CF patient) could go see him. My husband and I were both impressed... he knew his stuff and was VERY THOROUGH with his testing... he did both hormone and chromosomal testing on my DH in addition to the "standard" urological test. He was very well versed on what treatment would work best for us and what our odds would be. He doesn't sugar coat things but he is very compassionate (had to break out the tissues for me a couple of times

)--
REALLY SUCKS you are going through this but if you have to I would say Sherins is as good as they come. Good Luck!
