[|Human|] On day 13 th my follicle size was 18 x 16....was given ChatDoctor shot then itself...when i returned to hospital on day 15th for u/s for follicular study i got to know that the right side ovary/follicle had grown to 25 x 21....does this mean that i did not ovulate after 36 hours of ChatDoctor shot? Why is the size this big? Is it cyst?
[|AI|]  Hello, The cyst which is seen is most likely a corpus luteal cyst, which is formed after the rupture of the follicle that is ovulation. There are certain other signs also on USG to confirm ovulation like irregularity of cyst, free fluid in pelvis, increased blood flow around the cystic area which should also be taken into consideration. Still in small percentage of cases, the follicle might not rupture and remain as lutenist unruptured follicle. Hope this is helpful.
