<s>[INST] Respected Sir, My wife have been suffering from the LUF syndrome. We tried thrice for IUI but we could not able to sucesss for pregnant. In two times foliceles were not ruptued though shape and size was very good.The right side of phelopine tube is blocked and having one large folice in left overy. Give suggestion to us. YYYY@YYYY [/INST] Hi,It would best if you met a good IVF specialist and considered IVF.With one blocked tube, repeated unruptured follicles and 3 IUIs it is very unlikely that the IUI will succeed. IVF have a 40% chance of success in a good clinic and would be the best treatment to consider in your situation.Hope this helps.Regards. </s>
