Research Abstract	Fifty-eight women aged 18-33 years collected matched blood, saliva, and urine specimens once a week for four consecutive weeks (N=58*4=232 matched specimens). We 1) evaluated the effect of moderate underweight on fecundability of women using progesterone levels across a cycle, and 2) tested the validity of using salivary and urinary progesterone levels as a surrogate measure for blood progesterone levels. Among the participant women, no effect of underweight on progesterone levels was observed. The salivary progesterone levels seemed to differ according to past hormonal contraceptive use, whereas the blood or urinary progesterone levels did not differ.
