Prevalence of diminished ovarian reserve in Chinese women with follicular cysts and menstrual disorders.

OBJECTIVES: To assess the prevalence of diminished ovarian reserve (DOR) in Chinese women with follicular cysts and menstrual disorders and relationship to hormonal markers. METHODS: 117 women with follicular cysts and menstrual disorders, aged 24 ∼ 53 (39.19 ± 6.61) years; measurements of height, weight, follicle-stimulating hormone (FSH), luteinizing hormone (LH), E2, progesterone (Po), prolactin (PRL), total testosterone, AMH, follicular cyst diameter, endometrial thickness. Three age groups were compared: 1) 21 ∼ 30 years, 2) 30 ∼ 40 years, 3) > 40 years. RESULTS: Total prevalence of DOR 86.3%, in the groups 50%, 81.6%, and 98.4%, in group-3 significantly higher than in group-1 and 2. 34.2% of the 117 patients complained of cessation of regular menstruations or amenorrhea, 65.8% of abnormal uterine bleeding. Follicular cysts disappeard in cycle-1 for 98 (83.8%) and in cycle-2 for 117 (100%) patients. AMH decreased with age, significantly different between the three groups. Total testosterone in group-1 and 2 was significantly higher than in group-3. In total AMH had a negative correlation with age and E2 (p < 0.01) and positive correlation with total testosterone (p < 0.05). CONCLUSIONS: Assessing ovarian reserve with follicular cysts and menstrual disorders is important because often pointing to DOR. The overall prevalence of DOR was high; even young women (<40 years) with follicular cysts and menstrual disorders had a low level of AMH. So AMH can be used as a marker to define DOR with higher sensitivity than other markers like FSH and E2. Primarily, these results only apply to Chinese women and should be confirmed in further studies.
