Measuring ovarian reserve in women having laparoscopic surgery.

This study is measuring a hormone called Anti-Müllerian Hormone (AMH) in women who are having keyhole (laparoscopic) surgery on their pelvis or abdomen. AMH is a marker of ovarian reserve — in other words, it gives an idea of how many eggs a woman has remaining. Researchers want to find out how surgery affects AMH levels by taking blood samples before the operation and at two points afterwards. This will help doctors better understand how surgical procedures might affect future fertility.
