2017 Study Abstract

Objective
To investigate the association between urinary triclosan concentrations and antral follicle count (AFC), a well-accepted marker of ovarian reserve, among women from a fertility center.

Design
Prospective cohort study.

Setting
Hospital fertility center.

Patient(s)
A total of 109 women.

Intervention(s)
Urinary triclosan concentrations quantified by online solid phase extraction-high performance liquid chromatography-isotope dilution tandem mass spectrometry.

Main Outcome Measure(s)
AFC through transvaginal ultrasonography on the third day of an unstimulated menstrual cycle or on the third day of a progesterone withdrawal bleed.

Result(s)
The geometric mean of the specific gravity–adjusted urinary triclosan concentrations for the 225 samples provided by the 109 women was 13.0 μg/L (95% confidence interval [CI], 8.9, 19.1). Women had median (with interquartile range) AFC of 13 (8, 18). The specific gravity–adjusted urinary triclosan concentrations were inversely associated with AFC (−4%; 95% CI, −7%, −1%). Women with triclosan concentrations above the median had lower AFC compared with those whose triclosan concentrations were equal to or below the median, with an adjusted difference of −3.2 (95% CI, −3.9, −1.6) among those with a body mass index <25 kg/m2 and −1.8 (95% CI, −3.2, −0.3) among those who were <35 years old.

Conclusion(s)
Specific gravity–adjusted urinary triclosan concentrations were inversely associated with AFC in women seeking care at a fertility center. This association was modified by age and body mass index, with the younger and leaner women showing larger decreases in AFC.
