This study aimed to compare the effectiveness of NAC plus low dose contraceptive with low dose contraceptives alone. This was a randomised trial on a sample of women who underwent conservative laparoscopic surgery for ovarian endometrioma. Patients were randomly assigned either to the NAC plus low dose contraceptive group ( = 48) or low dose contraceptive alone ( = 52). To evaluate the recurrence rate transvaginal ultrasound was performed. Pelvic pain was assessed using a visual analogue scale (VAS). All assessments were performed at two points in time: 3 and 6 months post-surgery and compared between the two regimens. The findings indicated that reduction in the recurrence rate of endometrioma and pelvic pain were similar between both groups. The findings showed that adding N-acetylcysteine to low dose contraceptive treatment has a similar effect in reducing the recurrence rate of endometrioma and pelvic pain when compared to low dose contraceptives alone.Impact statement Endometriosis is a frequent benign disease-producing inflammatory response with mild to severe symptoms. Although surgical removal of ectopic lesions is the first-line intervention, the recurrence rate of the disease is high. Thus this study aimed to compare the effectiveness of N-acetylcysteine plus low dose contraceptive with low dose contraceptive alone. The findings showed that adding N-acetylcysteine to low dose contraceptive treatment has a similar effect in reducing the recurrence rate of endometrioma and pelvic pain when compared to low dose contraceptives alone. It is recommended to increase the duration of drug administration in future studies.
