Changes in laboratory parameters. (A) Serum hCG (measured in international units per liter), estradiol (E2; in picograms per milliliter), and testosterone (T; in nanograms per deciliter) were all significantly higher than baseline after 1 week on study. Progesterone (P; in nanograms per milliliter) did not change from baseline. (B) Serum albumin was significantly higher at days 28 and 56 in Arm 2 only. Data are presented as mean ± standard error of the mean (SEM). *P < .05 compared with baseline.
