Abstract:
Objective To investigate the change of CNP (C-natriuretic peptides) in patients with PCOS (polycystic ovary syndrome) undergoing in vitro fertilization-embryo transfer (IVF-ET) with GnRH-α longprotocol for controll ovarian hyper-stimulation(COH).Methods From March 2012 to September 2014,22cases patients with PCOS undergoing IVF-ET in the Reproductive Medical Center of the Center Hospital of JiangMen were selected as study group(Group 1),and 32 cases patients with normal ovarian reserve,the age younger than 35,and the number of oocytes retrieved more than 6 at the same period were selected as control group(Group 2).The level of serum CNP and estradiol(E2) on the day of human chorionic gonadotropin (HCG) and retrieving oocytes,the level of CNP and E2 in follicular fluid were analyzed.In additional,the levels of CNP and E2 in follicular fluid of different fertility and embryo quality were compared.Results (1) CNP and E2 on the day of HCG were significantly higher than that on the day of retrieving oocytes (CNPof Group 1:(107.21±78.55) μg/L vs.(73.01±55.99) μg/L,CNP of Group 2:(69.16±32.39) μg/L vs.(44.11±27.23) μg/L;E2 of group 1:(5231.38±1489.00) ng/L vs.(1985.52±662.54) ng/L,E2 of Group 2:(3678.45±969.57) ng/L vs.(1567.71±493.93) ng/L;t =2.968,2.752,8.147,14.567;P＜0.05).CNP and E2 on the day of retrieving oocytes and E2 on the day of HCG of Group 1 were higher than that of Group 2(t=2.866,2.227,2.173;P＜0.05).CNP in follicular fluid in Group 1 was higher than that in Group 2,but E2 of in follicular fluid in Group 1 was lower than that in Group 2 (t =2.244,-2.650;P＜0.05).(2) In Group 1,CNP and E2 in follicular fluid of normal fertility were lower than that of unnormal fertility,and E2 in follicular fluid of unnormal fertility were higher than that of no-fertility,and there were significant differences(t =-6.117,-2.374,2.760;P＜0.05).(3) In Group 2,only E2 in follicular fluid of unnormal fertility were higher than that of no-fertility,and there was significant difference(t=2.658,P＜0.05).(4) In 2 groups,CNP in follicular fluid of high-quality embryo were lower than that of non-high-quality embryo,and there was significant difference (t =-2.910,-2.029;P＜0.05).CNP in follicular fluid of non-high-quality embryo in Group 1 were higher than that in Group 2,but E2 in follicular fluid of non-high-quality embryo in Group 2 were higher than that in Group 1,and there were significant differences (t =2.141,-2.009;P ＜ 0.05).Conclusion There are differences in the change of CNP in the patients with PCOS and non-PCOS,and there are some deficiencies of the first meiosis in the patients with PCOS.
