Abstract:
BACKGROUND:More and more scholars have called for the cumulative live birth rate (CLBR) of a complete ovarian stimulation cycle as a key indicator for assisted reproductive technology. This research aims to study the CLBR of the first ovarian hyperstimulation cycles and analyze the related prognosis factors that might affect the CLBR.
METHODS:Our retrospective study included first in vitro fertilization or intracytoplasmic sperm injection (IVF/ICSI) cycles performed between January 2013 to December 2014. A total of 17,978 couples of first ovarian hyperstimulation IVF/ICSI cycles were included. The study was followed up for 4 years to observe the CLBR. The multivariable logistic regression model was used to analyze the prognosis factor, P value of <0.05 was considered statistically significant.
RESULTS:The cumulative pregnancy rate was 58.14% (10,452/17,978), and the CLBR was 49.66% (8928/17,978). The female age was younger in the live birth group when compared with the non-live birth group (30.81 ± 4.05 vs. 33.09 ± 5.13, P < 0.001). The average duration of infertility was shorter than the non-live birth cohort (4.22 ± 3.11 vs. 5.06 ± 4.08, P < 0.001). The preliminary gonadotropin used and the total number of gonadotropin used were lower in the live birth group when compared with the non-live birth group (both P < 0.001). Meanwhile, the number of oocytes retrieved and transferrable embryos were both significantly higher in the live birth group (15.35 ± 7.98 vs. 11.35 ± 7.60, P < 0.001; 6.66 ± 5.19 vs. 3.62 ± 3.51, P < 0.001, respectively).
CONCLUSIONS:The women's age, body mass index, duration of infertility years, infertility factors, controlled ovarian hyperstimulation protocol, the number of acquired oocytes, and number of transferrable embryos are the prognosis factors that significantly affected the CLBR.
