<s>[INST] Hi, I am 28 Years old. I have been trying to concieve since last 1 year but with no result. I have got my initial checkups done. Thyroid is normal, HCG test is normal. Last month I got follicular study done nad on 17th day my follicle size was 27mm but it was not ruptured yet. can this be the reason of me not able to concieve. Please help [/INST] Hello, Thanks for the query to H.C.M. Forum. Usually when dominant follicle attain the size of 20 mm approximately it rupture and liberate ovum . In your case follicle maturation occurs but it did,t liberate ovum , that was the reason of not getting pregnancy. In my opinion once again consult one more gynecologist and get his opinion that what was wrong?Only follicles study will find out the exact reason .Good luck. Dr. HET </s>
