Hey there, Sue,
Hysterosonography is a technique by which the uterus can be photographed offering more detail than a regular US, a TVUS, and sometimes, even a D&C. An ultrasound is done after the uterus is partially filled with sterile saline(introduced through the vaginal canal and cervix). From what I have read, the procedure is only slightly uncomfortable, and, it offers a great deal more information.
The follicles being referredd to are the "fingers" that guide the egg into the fallopian tube at ovulation; I am not certain what, if anything, is meant by 'physiologic' preceeding the word.
I am not absolutely certain, but I seem to remember 6mm to be in the average endometrial thickness.
Your patience is quite rare in this arena!
I hope Peace continues to follow you dian
Thank you for responding. i was able to get a hold of my doctor and he called the ob/gyn i am going to see and asked her to see me sooner. so, i have an appointment feb.9 instead of feb.21. i am really happy about that, so i can try to find out what is going on. thanks again.
