Time-to-Pregnancy Associated With Couples Use of Tobacco Products

Conclusions:
Compared with never users, smokeless tobacco did not alter TTP in our cohort; however, TTP was shorter compared with smokers. We observed longer TTP in male and female smokers; cadmium may partially contribute.

Implications:
Both partners’ preconception smoking contributed to longer TTP, highlighting the importance of both partners’ lifestyles in healthy reproduction and underscores the need for couple-based preconception guidance. The male’s contribution is a new finding. Higher cadmium levels may partially contribute to longer TTP in smokers, particularly among females. Though we do not observe longer TTP among a small sample of smokeless tobacco users compared with never tobacco users, we observe shorter TTP compared with smokers. Further work is needed to more thoroughly delineate the relationship between smokeless tobacco use and TTP and possible mechanisms of tobacco use’s effects on reproduction.
