This study aimed to evaluate the value of serum AMH levels clinically and theoretically.Patients, Animals, and Methods: We detected the serum estradiol, follicular stimulating hormone (FSH), luteinizing hormone (LH), and AMH levels in 144 premenopausal women with breast cancer receiving cyclophosphamide-based chemotherapy. The hormone levels before and postchemotherapy were compared; the correlations among the hormones and amenorrhea and menstrual recovery were analyzed. In addition, the serum AMH levels were detected randomly in 177 normal healthy women and 36 normal female C57BL/6J mice of different ages; meanwhile, the status of ovarian follicles was also examined. Furthermore, 72 Balb/c nude mice with breast cancer were randomly assigned to three groups that received different doses of cyclophosphamide (CTX) (control, 100 mg/kg, and 200 mg/kg), and the alterations in serum AMH levels and ovarian follicles were recorded and analyzed.Results: Chemotherapy-induced amenorrhea was associated with prechemotherapy AMH levels, E2 levels, and FSH levels (P < 0.0001). The recovery of menstruation was associated with prechemotherapy AMH levels (P < 0.0001), but not with E2 and FSH levels (P > 0.05). In patients with breast cancer treated with chemotherapy, the serum AMH levels did not differ significantly between the pre- and post-chemotherapy periods in patients aged < 35 years (P > 0.05), whereas a dramatic reduction was detected in patients aged > 35 years (P < 0.0001). In healthy women, the serum AMH levels declined sharply after 35 years of age (P < 0.0001) and remained relatively stable at a younger age. Similar results were obtained in experiments using normal mice. The cancer-bearing mice exposed to 200 mg/kg CTX exhibited a significant decline in AMH levels and a remarkable decrease in the number of primordial and growing follicles (P < 0.0001).Conclusion: Our results indicate that AMH is an efficient marker for predicting postchemotherapy ovarian function exclusively in premenopausal female patients with breast cancer aged > 35 years.Keywords: anti-Müllerian hormone, ovarian function, cyclophosphamide, breast cancer
