Table 3 Ovarian reserve markers and pregnancy outcomes in patients of different ages within salpingectomy group and control group

From: Salpingectomy may decrease antral follicle count but not live birth rate for IVF-ET patients aged 35–39 years: a retrospective study

  Salpingectomy group Control group
  Group A1
(age <35 years, n = 376)
Group A2
(age 35–39 years, n = 158)
Group B1
(age <35 years, n = 995)
Group B2
(age 35–39 years, n = 393)
Basal FSH (IU/L) 7.57 ± 2.56 7.72 ± 2.57 7.62 ± 2.70 7.78 ± 2.77
Basal E2 (pg/ml) 45.52 ± 22.23 43.20 ± 19.36 46.37 ± 28.26 49.68 ± 37.68
Antral follicle counts 8.69 ± 4.35 6.75 ± 3.56a,b 8.25 ± 3.48 8.00 ± 3.71
Clinical pregnancy rate (%) 41.2 (155) 39.2 (62) 41.9 (417) 41.2 (162)
Spontaneous abortion rate (%) 14.8 (23) 17.7 (11) 13.9 (58) 17.9 (29)
Live birth rate (%) 33.0 (124) 29.7 (47) 34.0 (338) 31.6 (124)
Ectopic pregnancy rate (%) 5.2 (8) 6.5 (4) 5.0 (21) 5.6 (9)

  1. Abbreviations: FSH follicle-stimulating hormone, E2 estradiol. Values are expressed as mean ± standard deviation unless indicated otherwise
  2. Statistical differences were calculated using the Mann–Whitney U-test
  3. Clinical pregnancy rate, spontaneous abortion rate, live birth rate, ectopic pregnancy rate, and multiple pregnancy rate were calculated using the chi-square test or Fisher’s exact test
  4. Results are significantly different if P < 0.05
  5. aP<0.05 (vs. group A1)
  6. bP<0.05 (vs. group B2)
