In the published article, there was an error in Table 2 as published. The incorrect data was included in the last row of the table for 17-OH-progesterone as these were a duplicate of the testosterone values from a few rows above. The corrected table in this corrigendum (Table 1) and its caption Steroid hormone concentrations (nmol/L) in serum and follicle fluid and their relative increase upon CG beta treatment appear below on the next page.

Steroid hormone concentrations (nmol/L) in serum and follicle fluid and their relative increase upon CG beta treatment.
Mean values of steroid hormones (nmol/L) in serum and follicle fluid (FF) in relation to treatment group. The relative increase (%) of steroid hormone levels is indicated in parenthesis. *Denotes statistically significant difference compared with placebo (p<0.05). Results for FF and serum hormones are at oocyte retrieval. Steroid hormones were measured by different assays in serum and FF. hCG, human choriogonadotropin.
