Outcome of women with advanced pelvic endometriosis and women with tubal sterilization submitted to ICSI: a comparative analysis - Revista Brasileira de Ginecologia e Obstetrícia
Revista Brasileira de Ginecologia e Obstetrícia. 2005;27(10):599-606
PURPOSE: comparative analysis of the outcome of women with advanced pelvic endometriosis and women with tubal sterilization submitted to intracytoplasmic sperm injection (ICSI). METHODS: ninety-three infertile women, with normal menstrual cycle, without hormonal or surgical treatment during 12 months, body mass index of 20-25, ovaries with no tumors or cysts were included in the present study and divided into two groups: tubal sterilization (TUB), 39 women, and endometriosis (EDT), 54 women with III-EDT and IV-EDT, undergoing ovulatory induction using r-FSH and ICSI. Clinical and laboratorial data were compared. chi2, Fisher, Student’s t, and Mann-Whitney tests were employed. RESULTS: lower estradiol levels (2,243.1 vs 1,666.3; p=0.001) and lower number of follicles per patient (16.9 vs 13.9, p=0.001) were noted in EDT group, in spite of more units of r-FSH (1,775.6 vs 1,998.6; p=0.007, for TUB and EDT, respectively). There were no differences in the rates of retrieved oocyte (69 vs 73.5%; p=0.071) as well as in normal fertilization rates (83.7 vs 81.7%; p=0.563, for TUB and EDT, respectively. However, lower number of top quality preembryos were obtained in patients from EDT group (36.5 vs 24.8%, TUB and EDT, respectively; p=0.005). Total pregnancy (41.0 vs 42.6%; p=0.950) and implantation rates (13.9 vs 14.5%; p=0.905) were not different when groups TUB and EDT were compared. CONCLUSIONS: ovaries of women from EDT group seem to be less responsive to ovulatory induction with r-FSH. EDT seems to impair the mean number of follicles and top quality preembryos with no impairment of retrieved oocyte and fertilization rates. However, once obtained, preembryos from EDT patients are able to exhibit similar implantation potential and pregnancy when compared with patients from TUB group.
