Final answer:
To assess adhesions and blockages of the fallopian tubes caused by PID, laparoscopy is the most effective method, and blockages can be treated with IVF or surgery.
Step-by-step explanation:
Adhesions and blockages of the fallopian tubes due to pelvic inflammatory disease (PID) would be best assessed with laparoscopy. This surgical procedure involves inserting a tiny camera into the abdomen through a small incision to directly inspect the reproductive organs. Optionally, if a blockage is confirmed, it can be treated by opting for in vitro fertilization, or surgically removing the obstruction and then re-ligating the ends of the fallopian tubes.
