Impact of salpingectomy on ovarian response to hormonal stimulation in in vitro fertilization (IVF) cycles.
Article in Journal of ovarian research, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundThe coagulation-section of the mesosalpinx during the salpingectomy can lead to injuries on the ovarian vascularization, and thus to the ovarian response to hormonal stimulation. Does salpingectomy affect negatively the follicles recruitment in in vitro fertilization (IVF) cycles? We conducted a monocentric retrospective case-control study including all patients undergoing IVF cycle with a history of unilateral salpingectomy for hydrosalpinx (HSX) or ectopic pregnancy (EP) (Group S), and each of them was matched to two controls (Group C) treated in the same month, according to their: age, AMH level, and BMI. The difference in follicle recruitment the day of trigger between the two ovaries of each patient was calculated. The primary endpoint was the difference between the two groups in the total number of follicles with a diameter ≥ 13 mm. Secondary endpoints were the difference between groups regarding the number of (1) mature follicles (diameter ≥ 16 mm) and intermediate follicles [13.0-15.5 mm]; (2) cycle cancellation rate; and (3) total number of oocytes and mature oocytes retrieved. The same comparisons were also carried out on subgroups according to the indication for salpingectomy (HSX or EP).
results114 and 228 patients were included in Groups S and C, respectively. Compared to Group C, Group S patients showed a greater difference between ovaries in the total number of follicles recruited (0.76 ± 3.95 vs. -0.18 ± 3.37, p = 0.002) and in the number of mature follicles (0.51 ± 2.91 vs. -0.14 ± 2.85, p = 0.05). No significant differences were observed for the number of intermediate follicles, or the total number of oocytes or mature oocytes retrieved. However, the cycle cancellation rate was significantly higher in Group S (13.2% vs. 3.1%, p < 0.001). Subgroup analysis revealed no significant differences between each of the Group S subgroups (HSX and EP) regarding follicular recruitment. Nevertheless, both subgroups had significantly more cancelled cycles compared with their respective controls (HSX: 12.5% vs. 4.4%, p < 0.001; EP: 8.8% vs. 1.8%, p = 0.004).
conclusionSalpingectomy has a negative impact on follicles recruitement in IVF cycles. This risk must be taken into consideration when scheduling this surgery.
