Change Type: Update
Change Details: The original online version of this article was revised: In the abstract, the second sentence of the methods section read: “Total and free serum testosterone, dehydroepiandrosterone, androstenedione, dehydroepiandrosterone (DHEA), DHEA-sulfate, and sex hormone-binding globulin (SHBG) levels were analyzed.” It should have read: “Total and free serum testosterone, dihydrotestosterone, androstenedione, dehydroepiandrosterone (DHEA), DHEA-sulfate, and sex hormone-binding globulin (SHBG) levels were analyzed.” In addition, the middle dot (ꞏ) was missing in units such as “nmolꞏL<sup>−1</sup>” and “pmolꞏL<sup>−1</sup>”. In the discussion section, the citation “Haverinen et al. 2022, 2022” incorrectly displayed the year twice. The citation should read “Haverinen et al. 2022”. In the discussion section, hyperlinks were missing for the references “Haverinen et al. 2022; Wiegratz et al. 2003”. The following reference was inadvertently omitted from the reference list: “Abraham GE (1974). Ovarian and adrenal contribution to peripheral androgens during the menstrual cycle. J Clin Endocrinol Metab 39(2):340–346.
