<s>[INST] hello, im under infertility treatment. I was given 3 fsh injections and on day 14 my follicle size is @ 35 mm and endometrium thickness is @ 11 mm. Now I had a HCG shot 10,000 units. Could you please tell me whether 35 mm size can release a egg and could it be still a follicle or just a cyst? FYI - I had a laproscopy in order to puncture my cysts 2 months back... [/INST] Hi, 35mm follicle might be just be a cyst. But more importantly, if you didn't have cyst in previous scan of this cycle, it might indicate corpus luteum (formed after follicle is ruptured).  Considering the second optimistic property you can go ahead with treatment. </s>
