Male cigarette smoking and fecundity in couples attending an infertility clinic.
The relationship between male cigarette smoking and fertility was studied for 330 couples attending an infertility clinic. 59% did not smoke, 10% smoked between 1 and 5 per day, 8% smoked between 6 and 10 per day, 16% smoked 11-20 per day and 7% smoked more than 20 per day. There was no significant association between smoking and any semen parameter. 138 men had a female partner who was apparently normal. There was no significant difference in smoking habits between the 'normal' and 'abnormal' female groups. Couples were followed-up for up to 32 months. Nineteen women had a treatment independent conception within the 'normal' female group. There was no significant association between the number of cigarettes smoked and the fertility outcome.
