Endometrial thickness in women with ovulatory dysfunction

This study is designed to evaluate the relationship between endometrial thickness and clinical/biochemical parameters in women with chronic anovulation. One hundred and twenty women with ovulatory dysfunction were prospective included, endometrial thickness and endocrine and metabolic parameters were measured. The interval between the examination day and the day of the most recent menstrual bleeding (the anovulatory interval) for the studied subject was an average of 145 ± 186 days. The endometrial thickness averaged 7.1 ± 3.2 mm. Correlation analyses revealed that the endometrial thickness was positively correlated with body mass index but was not correlated with age, serum androgens, or estradiol (E2) levels. We further classified the subjects into two groups based on endometrial thickness: Group A, endometrial thickness <7 mm and Group B, endometrial thickness ≥7 mm. The anovulatory interval, follicle-stimulating hormone, luteinizing hormone, E2 and androgen levels were not significantly different between Groups A and B. Group B had higher body weight and more risk for metabolic syndrome. We concluded that endometrial thickness in women with ovulatory dysfunction is positively correlated with body weight status but is not correlated with serum androgens or E2 levels.
