As shown in Table2, on average, only 75 IU/day of Gn were used in
minimal stimulation IVF according to our stimulation protocol and 280.
67 IU/day of Gn were used in conventional stimulation protocol, which
was significantly different. The average oocytes retrieved in MS-IVF was
1.39 which was less than 2.26 oocytes in conventional
IVF(p<0.05), the average available embryo was 1.51 in
conventional stimulation and 0.90 in MS-IVF(p<0.05), the good
quality embryo was 1.01 in conventional stimulation and 0.63 in
MS-IVF(p<0.05). Even though there were statistical differences
in average oocytes, the average embryos available and the good quality
embryos obtained between C-IVF and MS-IVF, though slightly higher, there
were no statistical differences in clinical pregnancy rate (18.99% in
C-IVF vs 16.93% in MS-IVF, p>0.05) in the first fresh
transfer cycle. There were also significant differences in the
gonadotrophin stimulation days between groups, the time interval between
initiation of stimulation and trigger day was significantly shorter in
MS-IVF.
