Abstract
Purpose
Is it safe and effective to perform controlled ovarian stimulation (COS) and oocyte retrieval (OR) in prepubertal and peripubertal patients?
Methods
In this retrospective cohort study, data of 20 pre-/peripubertal patients who underwent COS and OR for the purpose of oocyte cryopreservation (OC) between 2008 and 2023 were reviewed. Following COS, all OR procedures were performed transabdominally using a vaginal ultrasound probe. Ovarian reserve was assessed by serum FSH, LH, estradiol, AMH, and antral follicle counts (AFC) in all subjects. All mature oocytes were vitrified.
Results
Mean age of the patients was 15.05 ± 1.87, mean AMH was 0.84 ± 0.8 ng/ml, mean FSH was 6.39 ± 3.95 IU/L, mean estradiol was 61.6 ± 51.9 pg/ml, mean LH was 4.69 ± 3.46 IU/L, and mean AFC was 5.5 ± 5.82. Among the patients, 12 had regular menstrual cycle, 5 had irregular menstrual cycle, whereas 3 patients still did not have their menarche yet. The indications for OC were as follows: primary ovarian insufficiency (n = 7), ovarian surgery for ovarian tumors (n = 5) or ovarian torsion (n = 1), mosaic Turner syndrome (n = 2), acute lymphoblastic leukemia (n = 1) anaplastic B-cell lymphoma (n = 1), Ewing’s sarcoma (n = 1), Noonan syndrome (n = 1), and Thalassemia (n = 1). The mean number of oocytes retrieved, MII oocytes frozen, and maturation rate were 5.11 ± 5.0, 3.92 ± 4.48, and 75.1 ± 25.6%, respectively. Stepwise linear regression analysis demonstrated a positive correlation between AFC and number of total oocytes retrieved and number of MII oocytes. In the case diagnosed with Noonan syndrome, all 7 retrieved oocytes were MI and all frozen at MI phase. No patient had any complication related to COS or OR.
Conclusion
Even though number of the enrolled subjects is limited and mean AMH is lower in our cohort, we demonstrated that performing COS and OR is safe in pre-/peripubertal patients. If required, transabdominal route can be performed in this age group for OR. AFC appears as a prognostic factor for stimulation outcome in this age group. Pediatric patients or young adolescents at risk for primary ovarian insufficiency should not be discouraged from utilizing OC.
