We will conduct this study to estimate the effect of laparoscopic cystectomy on ovarian reserve in endometriotic cysts versus non-endometriotic cysts.
After eligibility and consenting, all participants aged 18-45 years presented to Benha University or the Endometriosis center with ovarian cyst diagnosed via transvaginal ultrasound or MRI will undergo laparoscopic ovarian cystectomy. Data will be collected regarding, 1. Baseline clinical data will be collected by healthcare providers including age, BMI, parity, previous pelvic surgery, duration and type of infertility, duration of cyst once diagnosed till time of laparoscopic surgery, laterality of cyst and size. 2. Baseline ovarian reserve will include * AMH will be measured within 1 month before laparoscopic surgery. * AFC will be measured within 1 month preoperative via transvaginal ultrasound in the early follicular phase of the menstrual cycle (cycle days 2-4). * FSH will be measured within 1 month preoperative between day (2 and 4) of the menstrual cycle. 3. Intraoperative data will be collected by trained operating room nurse including: * Operative time which is the time lapse between insertion of Veress needle trocar for preparation till the removal of the 10 mm umbilical trocar. * Estimated intraoperative blood loss(mL) where it calculated by = (Total weight of wet gauze after surgery (g) - Total weight of dry gauze before surgery (g)) + (Amount of fluid in suction bucket (g) - Weight of flushing fluid (g)used) * laterality of the Cyst, number of cauterizations, cyst rupture, adverse effects including soft tissue or organ injury. 4. Postoperative follow up * Early postoperative follow up with first 24-48 hours during hospital admission recording complications such as fever, intraperitoneal hemorrhage or postoperative pain calculated by NPRS (Numeric Pain Rating Scale) (0-10) where 0 mean no pain and 10 mean intense or intolerable pain or through VAS (Visual Analogue Scale). * Longterm complications will be structurally soliced via telephone calls every 2 weeks till the end of the follow-up period including fever, surgical site infection, readmission or reoperation. * At 3-month postoperative AMH, FSH will be re-evaluated at the same laboratory, and AFC will be re-evaluated by the same ultrasonography.

Laparoscopic excision of ovarian cyst under general anesthesia. The procedure includes: (1) CO₂ pneumoperitoneum creation via Veress needle through a 1-cm umbilical incision until intraabdominal pressure reaches 15 mmHg; (2) insertion of a 10-mm umbilical trocar and telescope; (3) placement of two or more 5-mm ancillary trocars under direct visualization; (4) incision of the ovarian capsule using monopolar scissors; (5) identification and careful dissection of the cyst wall from adjacent ovarian tissue using traction with grasping forceps; (6) hemostasis achieved using electrocoagulation or sutures; (7) plication and approximation of the ovarian incision edges; (8) for endometriosis cases, excision or cauterization of visible endometriotic lesions; (9) histopathological examination of the excised specimen to confirm diagnosis. The procedure is performed in both arms (endometriotic and non-endometriotic cysts) using identical surgical techniques.

RECRUITINGAbsolute Change in Serum Anti-Müllerian Hormone (AMH) Level
The absolute change in serum anti-Müllerian hormone (AMH) level from baseline to 3 months after laparoscopic ovarian cystectomy, calculated as the difference between preoperative AMH value (measured within 1 month before surgery) and postoperative AMH value (measured at 3 months after surgery). Comparison will be made between the endometriotic cyst group and the non-endometriotic cyst group.
Time frame: Baseline (preoperative, within 1 month before surgery) and 3 months postoperatively
Preoperative AMH Cutoff Value Predicting Postoperative AMH ≥ 1 ng/ml
Receiver operating characteristic (ROC) curve analysis to determine the optimal preoperative serum AMH cutoff value that predicts maintenance of serum AMH ≥ 1 ng/ml at 3 months postoperatively. Sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) will be calculated.
Time frame: Baseline (preoperative, within 1 month before surgery) and 3 months postoperatively
Change in Antral Follicle Count (AFC)
The change in antral follicle count (AFC) from baseline to 3 months after laparoscopic ovarian cystectomy, assessed via transvaginal ultrasound in the early follicular phase (cycle days 2-4). Comparison will be made between endometriotic and non-endometriotic cyst groups.
Time frame: Baseline (preoperative, within 1 month before surgery) and 3 months postoperatively
Change in Serum Follicle-Stimulating Hormone (FSH) Level
The change in serum follicle-stimulating hormone (FSH) level from baseline to 3 months after laparoscopic ovarian cystectomy, measured on cycle days 2-4. Comparison will be made between endometriotic and non-endometriotic cyst groups.
Time frame: Baseline (preoperative, within 1 month before surgery) and 3 months postoperatively
Correlation Between AMH Change and Clinical Variables
This platform is for informational purposes only and does not constitute medical advice. Always consult a qualified healthcare professional.
Analysis of the correlation between the change in serum AMH level and various clinical variables, including number of cauterizations, cyst size (cm), laterality (unilateral/bilateral), cyst type (endometriotic/non-endometriotic), age (years), and body mass index (BMI, kg/m²). Pearson or Spearman's rank correlation coefficients will be calculated as appropriate.
Time frame: 3 months postoperatively
Intraoperative and Postoperative Complications
Description and comparison of intraoperative and postoperative complications between the endometriotic and non-endometriotic cyst groups, including: intraoperative cyst rupture, organ injury (bladder, bowel, uterus, fallopian tubes, major blood vessels), hemorrhage; early postoperative complications (within 24-48 hours) including fever, intraperitoneal hemorrhage, and postoperative pain measured by NPRS (0-10) or VAS; and long-term complications (up to 3 months) including surgical site infection, readmission, reoperation, and cyst persistence or recurrence.
Time frame: Intraoperative period, early postoperative period (24-48 hours), and up to 3 months postoperatively
