For males, testosterone and progesterone levels are presented; for females, estradiol and progesterone concentrations are shown.
Data were expressed as Median (min, max). For data analysis, samples below the limit of quantitation (LOQ) of each analyte were assigned the LOQ value (Testosterone: 5 pg/mL; Estradiol: 0.5 pg/mL).
