Bbhope.... the main BTs that DH had were: Inhibin B, Androstenedione, TSH, FSH, LH, Oestradiol, Testosterone, SHBG, Free Androgen Index and micro-deletion of the Y chromosone. If you do go to Dr G then it would be very useful to have those results before you see him. I don't know if he does phone consults, but that would also be worth investigating, but again you would need all the BTsdone at your end first of all. Dr G uses some formula with some of those results to come up with his percentage rating, however with my DH he never gave us a percentage, but said words like "excellent chance" and "very good chance". However here are a few stats:
- sperm found in up to 70% of men who have FSH levels greater than three times normal (hence why Dr G tests FSH, when most FS only think of it as a female test). Other studies say that FSH has no correlation.
- sperm is found in app. 50% of men, who have not had sperm found by other means (e.g. aspirations and biopsies). This alone, is a major reason for trying mTESE.
- sperm is found in almost 80% of men who have had some sperm found by other means. My DH technically landed in the successful 80%, but unfortunately just finding 1 sperm, didn't really amount to much :-((
- percentage chance of finding sperm in men with Sertoli cell-only is only about 20-25%.
All of those stats are pretty easy to find on the internet, but it's things like that that Dr G uses to give his "percentage chance" of finding sperm. Hope that's of use?
