Demographic and index stimulated IVF cycle characteristics
No significant differences were found between the two groups with regard to age of women, basal AFC, basal FSH level, number of first IVF cycles, duration of infertility, body mass index, cause of infertility, proportion of primary infertility and proportion of ICSI (Table 1).
The starting dose, total hMG/FSH dose and serum estradiol/LH levels on the day of hCG in the PPOS groups was higher than that in the antagonist group. There was no difference in duration of stimulation between the two groups. Two women in the PPOS groups experienced premature LH surge while none was seen in the antagonist group. No patient experienced moderate or severe OHSS during the study. (Table 1)
No differences were found in number of oocytes obtained, the fertilization rate, cleavage rate, blastocyst formation rate, number of good quality embryos and number of embryos frozen between the two groups. (Table 1)
