Abstract | BACKGROUND: METHODS: RESULTS: In premenopausal women, caffeine intake was inversely associated with luteal total and free estradiol, and positively associated with luteal progesterone levels (P-trend = .02, .01, .03, respectively). Coffee intake was significantly associated with lower luteal total and free estradiol levels, but not luteal progesterone levels (P-trend = .007, .004, .20, respectively). Among the postmenopausal women, there was a positive association between caffeine and coffee intake and SHBG levels (P-trend = .03 and .06, respectively). No significant associations were detected with the other hormones. CONCLUSIONS:
