It has come to the authors’ attention that their presentation of the progesterone data in the manuscript is inconsistent and has the potential to generate confusion to readers. Unfortunately, there were two typographical errors in the manuscript that should be corrected.
The title lists the progesterone units as ng/dl. In fact, the correct unit is ng/ml. This same error is made on page 1397 (within the materials and methods section). This should also read as ng/ml.
Also, to be clear, the units for progesterone levels should be ng/ml in figure 1.
