Aim:
To evaluate the influence of smoking on the outcome of COH and IUI in subfertile couples.
Patients And Methods:
We reviewed the medical files of all consecutive women, age =35 years, attending our infertility clinics over an eigth-year period. Data on patient age, smoking habits, and variable related to infertility-treatment were collected from the files.
Results:
A total of 2,318 cases were evaluated: 1,803 in nonsmoking patients (n = 679) and 515 in smokers (n = 206). The smokers used significantly more gonadotropin ampoules and gained a thinner endometrium on the day of hCG administration than the nonsmokers (p < 0.016 for both). There were no between-groups differences in patient age, duration of gonadotropin stimulation, number of follicle >14 mm in diameter, or E2 levels on the day of hCG administration.
Conclusion:
Smokers undergoing COH with IUI required a significantly higher gonadotropin dosage than nonsmokers in order to achieved a comparable pregnancy rate.
