Abstract

Objective To assess the endocrine milieu in follicles of stimulated cycles comparing women with and without endometriosis. Steroids were measured in follicular fluid (FF) and in in vitro culture of granulosa-luteal cells, and this status was related to the quality of the embryos obtained after IVF. Design Case-control study. Setting IVF program at the Instituto Valenciano de Infertilidad. Patient(s) Twenty-four women with laparoscopically documented endometriosis and 26 controls undergoing IVF. Intervention(s) Individual follicular aspiration, oocyte isolation, FF storage, and preparation of luteinized granulosa cells for culture; oocyte insemination and embryo cleavage in standard IVF. Main outcome measure(s) Serum (day of ovum pickup) and FF measurements of estradiol, progesterone, testosterone, and androstenedione. Secretion of progesterone was measured in the cell-conditioned medium. Results were compared between patients with endometriosis and controls, as well as between oocytes that yielded embryos of different quality. Result(s) Levels of progesterone in the FF increased with the severity of the disease, whereas testosterone accumulation in the FF decreased with the severity of the disease. An increase in progesterone accumulation in vitro was observed in basal and hCG-induced granulosa cell cultures. No difference was observed in terms of embryo quality, and no steroid marker was able to identify follicles with oocytes that displayed embryos of good or bad quality under the inverted microscope. Conclusion(s) The data show differences in the steroidogenesis of follicles from stimulated women with and without endometriosis. These changes indicate good endocrine health but are not predictive of embryo quality.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Pellicer et al. reported decreased testosterone accumulation in the follicular milieu with increasing severity of endometriosis in IVF cycles.

    “Pellicer et al . [19] assessed steroid levels in follicular milieu in patient with endometriosis with in vitro fertilization (IVF) cycle and reported decreased T accumulation with the severity of the disease.”
  • More severe endometriosis predicts lower follicular testosterone.

    “More severe disease predicted lower follicular testosterone in another study (Pellicer et al., 1998).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
