Prospective study of cigarette smoking and fecundability.

ABSTRACT:

Study question

To what extent is cigarette smoking associated with reduced fecundability?

Summary answer

Current female smokers, particularly those who had smoked ≥10 cigarettes/day for ≥10 years, had lower fecundability than never smokers, but current male smoking and passive smoking in either partner showed little association with reduced fecundability.

What is known already

Female smoking has been identified as a cause of infertility, yet there has been limited characterization of the dose and duration at which an effect is observed. Results for male active smoking and passive smoking in both partners are less consistent.

Study design, size, duration

We analyzed data from a North American internet-based preconception cohort study of 5473 female and 1411 male
