Candiani M, et al. – In this small, multicenter, randomized clinical trial, researchers investigated the efficacy of CO₂ laser vaporization vs traditional cystectomy in treating endometrioma in terms of ovarian reserve preservation in a cohort of 60 study participants who were randomized to laparoscopic stripping: cystectomy or CO₂ laser vaporization. On assessing both antral follicle count and serum anti-Müllerian hormone levels as measures of ovarian reserve, they identified that CO₂ technology caused minimal damage to adjacent healthy ovarian tissue and could be an alternative treatment for endometrioma.
