Abstract

|
|
Purpose: Various causes may be the etiology of gynecomastia. We investigated the levels of serum estradiol (E2), testosterone (T), ratio of E2 to T (E2/T) as well as associated diseases, drugs as the cause of gynecomastia.
Materials and Methods: E2, T, E2/T in 37 patients from gynecomastia patients (GP) and 10 healthy men were measured, and the associated diseases and drugs in 68 GP were also evaluated. Ultrasound for the adrenal gland diseases, physical examination or ultrasound for the testicular pathology were performed.
Results: The cause of gynecomastia varied according to the age. The levels of E2, T, E2/T in control group (CG) were 35.3 ± 3.9 pg/㎖, 5.0 ± 0.4 ng/㎖, 7.1 ± 0.5. Those in GP were 48.7 ± 7.1 pg/㎖, 4.3 ± 0.3 ng/㎖, 12.0 ± 1.8, respectively. The difference of E2/T as well as E, T between CG and GP was not significant. Various associated diseases or drugs were found in GP. Adrenal diseases or testicular cancer were not found in GP.
Conclusions: The difference of E2/T between CG and GP is not the only cause of gynecomastia. Thus, the consideration of the age as well as associated diseases or drugs will be helpful for the better understanding of high E2/T as the cause of gynecomastia.
