  1. *Values are presented as means ± standard deviation or as percentages. Patient characteristics did not differ between both groups except for DHEAS (P < 0.001), total testosterone (P < 0.001) and free testosterone (P < 0.01), all three the consequence of DHEA supplementation for women with LFOR between baseline evaluation and IVF cycle start. For further detail, see text.
  2. Percentages among antibodies represent percentages of patients with positive antibody tests.
  3. **BMI, body mass index.
  4. ***Defined by presence of at least 1 positive laboratory test.
