POSTER VIEWING SESSION - REPRODUCTIVE (EPI) GENETICS

Results: 10648 AID cycles were performed from January,2007 to September, 2009 in our Hospital and resulted in 2364 clinical pregnancies,the clinical pregnancy rate was 22.20%. All 10648 cycles were followed up completely and the follow-up rate was 100%.The average age of women was 29.73 3.3 yrs (20-46 yrs),the average duration of infertility was 3.2 1.9 yrs (1-14 yrs); the abortion rate was 3.28% (314/2364)(including 2 cases of molar pregnancy), the ectopical pregnancy rate was 0.68% (16/2364),1 case had ectopic and intrauterine pregnancy at the same time. The rate of delivery was 89.72% (2121/2364); among 2061 neonates,1058 were male infants and 1003 female infants,the male to female ratio was 105:100; the rate of low birth weight was 2.52% (52/2121);total 15 neonates died;the delivery rate of twins was 1.60% (34/2121);the delivery rate of mutiples was 0.28% (6/2121);the incidence of birth defects was 0.73% (15/2061).18 induced abortion; the rate of Cesarean section was 59.78% (1268/2121). The abortion rate and incidence of low birth weight of multiple pregnancies was higher than that of singleton;the average age in abortion group was significantly higher than that of average age. The rate of Cesarean section was significantly higher that that of natural conception. (P < 0.05). Conclusions: The abortion rate, incidence of low body weight and birth defects after AID were not higher than those of natural conception. The rate of ectopic pregnancy after AID was higher than that of natural conception women.Older women after AID had higher abortion rate. The rate of abortion and birth of low birth weight infants were higher in mutiple pregnancies.
