Abstract

Objective:

Using of cumulative live birth rate (CLBR) per oocytes retrieved cycle, to assess the clinical outcomes of in vitro fertilization or intracytoplasmic sperm injection (IVF/ICSI) , and to explore impact factors on CLBR following utilization of all fresh and frozen embryos in one complete IVF/ICSI cycle using gonadotropin-releasing hormone (GnRH) agonist, GnRH-antagonist and clomiphene mild stimulation protocols.

Methods:

Of the patients who underwent IVF/ICSI from January 1st, 2014 to December 31st, 2015 in the First Affiliated Hospital, Nanjing Medical University, a total of 6 142 oocytes retrieved cycles were included. The clinical and laboratory parameters of different ovarian stimulation protocols, and the effects of the age, number of oocytes retrieved and number of embryos available on the CLBR of each oocytes retrieved cycle were analyzed.

Results:

The CLBR was 69.0% (2 004/2 906) in the GnRH-agonist protocol versus 67.4% (644/955) in the GnRH-antagonist protocol (P>0.05); the CLBR of clomiphene mild stimulation protocol was 53.2% (1 215/2 281) , significantly lower than those of the other two protocols (all P<0.05). The CLBR significantly decreased with age increased. When divided into four groups according to the patients' age, we found that CLBR were not statistically significant using three different protocols in the 20-25 years old group (all P>0.05). There was a strong association between the number of oocytes retrieved and embryos available on CLBR. CLBR rose significantly with an increasing number of oocytes up to 6, then the rising trend slowed down. Patients were categorized into four groups according to the number of oocytes retrieved, CLBR was significantly higher using GnRH-antagonist protocol (50.0%) than mild stimulation protocol (37.0%) in low ovarian responder (0-4 oocytes) group (P<0.05) . The CLBR were no significant difference among three protocols in normal (10-15 oocytes) and high responders (≥15 oocytes) group (all P>0.05) . The incidence rate of ovarian hyperstimulation syndrome in GnRH-agonist protocols (5.2%, 152/2 906) were significantly higher than those of GnRH-antagonist (4.4%, 42/955) and clomiphene mild stimulation protocols (1.5%, 34/2 281; all P<0.05) .

Conclusions:

CLBR is an important index to assess the clinical outcomes of IVF/ICSI. Age, number of oocytes retrieved and embryos available could affect CLBR obviously. According to the different age and ovarian response of patients, we should design ovarian stimulation protocols based on target oocytes number in order to get higher CLBR and reduce complications.
