Analysis of the clinical pregnancy rate of in vitro fertilization and embryo transfer with three tropic hyperovulation programmes

Objective:To determine on the clinical pregnancy rate of in vitro fertilization and embryo transfer (IVF-ET) with three tropic hyperovulation programmes(THOP).Methods:136 cases with sterility were performed with three THOP for IVF-ET and divided into 3 groups:Group 1(n=51),high-purified follicle-stimulating hormone (HP-FSH,goods name:Metrodine) decreased progressively for tropic hyperovulation and GnRH-a (goods name:Buserelin) was used for long programme and down regulation.HP-FSH was decreased progressively from the 3rd day of menstruation.Group 2(n=50),HP-FSH+hMG were combined to decrease progressively for long programme and down regulation for tropic hyperovulation.Group 3(n=35),hMG was used to increase progressively for tropic hyperovulation.The three programmes of tropic hyper ovulation were analysed for the average number of ova obtained,fertilized cleavage of oocytes,implantation,and number of clinical pregnancy,clinical pregnancy rates in IVF-ET cycles.Results:Group 1,average number of ova obtained was 10.13±4.49,number of fertilized ova 7.83±4.13,rate of fertilization 69.82%,number of cleavage 7.75±5.94,number of transferred embryos 3.68±1.08,and number of cleavage 7.62±4.19,number of transferred embryos 3.88±1.17,and number of clinical pregnancy 18,clinical pregnancy rate 35.29%.Group 2,average number of ova obtained was 9.16±5.49,number of fertilized ova 6.84±4.23,rate of fertilization 74.67%,number of cleavage 6.5±4.22,number of transferred embryos 3.68±0.99,and clinical pregancy 15,clinical pregnancy rate 30.0%.Group 3,average number of ova obtained was 11.3±7.64,number of fertilized ova 7.89±5.36,rate of fertilization,77.29%,number of clinical pregnancy 15,clinical pregnancy rate 42.86%,drug used in group 1 and group 2,there was signifiant difference in drug used in group 1 and group 2 (P<0.01),in group 2 vs group 3,there was significant difference too.In the three groups of clinical pregnancy rates of IVF-ET,there were no statistical difference among dinical pregnancy rates of IVF-ET of the three groups. Conclusions:Clinical pregnancy rate for IVF-ET is high and no difference was found in all three groups.hMG is used for tropic hyperovulation for IVF-ET reveals significantly deceased OHSS and high pregnancy rate in 26 patients with polycystic ovary syndrome (PCOS).
