<s>[INST] Hi, I am due to have an IUI treatment, however now have a cervical polyp.  One RE advises removal prior to treatment another does not.  As am 41 in 2 months time i dont really have the time  for removal and would prefer if i didnt have to however could it interfere with implantation?  not sure how to proceed [/INST] Hi, if the Polyp is on external part of cervix, there is no need to remove it. It will not interfere with implantation.  If polyp is extending inside the cervix that means if it is endocervical then also it will not affect implantation, but it may cause some problems in doing GUI.  But I think it can be taken care of. So, you may not need removal. Hope I have answered your question. Regards Chat Doctor.  </s>
