↵2-150 Primary infertility defined as (a) having consulted a clinician about problems achieving a pregnancy, and never having achieved a pregnancy; and (b) having consulted a clinician about problems achieving a pregnancy, and never having achieved a pregnancy lasting ⩾24 weeks of gestation.
↵2-151 Presence or absence of monitoring for ionising radiation before first consultation for infertility (or estimated date of conception of first child for those with no reported fertility problem).
↵2-152 All workers aged ⩾40 at survey, who reported first attempting to have children after date of first employment. Date of first attempt at pregnancy taken as 6 months before first consultation for problems achieving pregnancy (or estimated date of conception of first child if no fertility problem reported).
↵2-153 Odds ratio adjusted for age at first consultation or first conception if no fertility problems and year of first consultation or first conception if no fertility problems.
↵2-154 Baseline group for all odds ratios.
↵2-160 For three men the dose before date of first conception was uncertain. No workers with fertility problems had uncertain doses before date of first consultation.
