Eleven women with polycystic ovary syndrome (PCO) were treated with Laparoscopic Multiple Punch Resection (MPR) of the ovarian follicle and capsule and studied by hormone analysis before and after MPR. In 90.9% of the patients, ovulation appeared to occur within 9 weeks and 63.6% conceived within 26 weeks. No changes in serum LH and FSH levels were seen before and after MPR, but testosterone levels which were in the upper normal range or slightly elevated before treatment were reduced after MPR. Endocrine responses to MPR were similar to those described previously after wedge resection. Laparoscopic MPR is a simple and least invasive method and makes it unnecessary to worry about periovarian adhesion after operation. Furthermore, other causes of infertility can be examined by laparoscopy. MPR appeared to be a promising alternative treatment for patients with PCO.
