Serum levels of GCT markers in healthy women or in women with GCT.

Measurements that exceeded the normal reference range are indicated in bold. For inhibin A and B (INHA and INHB), values beneath the detection thresholds by ELISA were defined as normal. For VCP, the reference value was set as the mean of healthy control band intensity in immunoblot analyses+2SD (253 arbitrary units). Note that serum inhibin usually becomes undetectable after menopause in healthy women. Interpretation of premenopausal inhibin values can be difficult due to their secretion both by growing ovarian follicles and by GCTs. NE: not evaluated.
