❗️New paper out now❗️

Female sexual function is important for reproductive health, relationship satisfaction, and positive sexual expression. Sexual function may be sensitive to environmental chemicals, but remains largely understudied in EH.

In their new paper, Dr. Samantha Schildroth and colleagues investigated associations of preconception phthalate exposure with validated measures of female sexual function in Pregnancy Study Online (PRESTO). These findings suggest a complex relationship between phthalate exposure and sexual function, highlighting the need for additional research on female sexual function to inform clinical practice.

Dr. Schildroth will be presenting on these findings at ISEE/ISES next Wednesday in the “Environmental chemicals and reproductive outcomes” session.
