Objective To determine the frequency of condom breakage and understand if couple took any measure（s） to protect against pregnancy when condom breakage happened. Methods It＇s a prospective follow-up study. A total of 1 562 subjects in 9 districts of Shanghai were selected. Subjects were divided into two groups. Totally 812 subjects were in condomlemergency contraceptive pills（ECP） combined regimen group and 750 subjects were in the group of condom only. Each subject used daily diary card to record the presence or absence of menstrual bleeding or spotting, each act of sexual intercourse, condom problem, together with brief details about use of condom/postcoital ECP. The selected subjects were interviewed at the end of 1st, 3rd, 6th, 9th and 12th month after enrollment with their diary to＇c＇ollect information mentioned above. Results The total condom breakage rate （CBR） of whole year was 0.53 per 1 000 condoms. The condom breakage ratio per 1 000 person months （CBRp） was 2.58. The result of multiple logistic regression showed that husbands＇ age, occupation and couples＂ condom using experience might affect the condom breakage. Compared with 〈30 years old husbands, subjects whose husbands were 30-34 years old and ≥35 years old could have higher CBR （RR=2.29, 4.07, respectively）. Compared with subjects whose husbands were medical staff, subjects whose husbands were teacher and scientific technician, manager, worker and service worker could have higher risk of condom breakage （RR=3.88, 9.30, 4.00 and 8.28, respectively）. Subjects with condom using experience might have lower risk of condom breakage （RR=0.44）. Conclusion The condom breakage rate was age, husband＇s occupation and condom using affecting the condom breakage. significant associated with husband＇s experience. Those might be the factors
