I ve gone through ur case in most cases of pcod synechiae is rare....it may be due to some bacterial infections associated with pelvic inflammatory disease or tb....since tb is ruled out...u don need to worry....once the synechiae reduces you have more chance of conceiving....if u are obese try to reduce ur weight....if you are still not able to conceive opt for in vitro fertilization intracytoplasmic sperm injection kindly consult obg specialist and ivf specialist
