In the paper
“The increase in serum luteinizing hormone and testosterone when male mice and hamsters are exposed to chemosensory stimuli from females appears to be absolutely dependent on vomeronasal integrity (Coquelin et al., 1984;Pfeiffer and Johnston, 1994).”

What the sources say
- Partly supportedcites Coquelin et al., 1984 sourceExperimental — accuracy not yet measured
The Results (page not provided) show that removing the vomeronasal organ greatly reduced LH responses to female urine in male mice. But some mice without the organ still responded to urine, and most responded to a freely behaving female, so the paper does not establish absolute dependence for all female stimuli. It reports a testosterone finding from another mouse study but does not study testosterone or hamsters itself. (LLM, conf=0.90)
- Partly supportedcites Pfeiffer and Johnston, 1994 sourceExperimental — accuracy not yet measured
The Discussion reports that vomeronasal removal eliminated androgen surges in hamsters investigating female vaginal secretions, and describes comparable LH findings for mice exposed to female urine. But it also says vomeronasal lesions did not eliminate hamster androgen surges during interactions with females; the claimed absolute dependence is therefore broader than the paper supports. The mouse testosterone surge is described as presumed rather than directly established by the cited mouse finding. (LLM, conf=0.89)

“The epithelium lining the human VNO is unlike that of VNOs in other species and unlike that of olfactory or respiratory epithelium in humans (Moran et al., 1991;Stensaas et al., 1991).”
§ Human Vomeronasal Organ Function: A Critical Review of Best and Worst Cases > Microanatomy
What the sources say
- Partly supportedcites Moran et al., 1991 sourceExperimental — accuracy not yet measured
The paper’s conclusion describes the human VNO lining as unlike other epithelial linings described in the human body, supporting the comparison with human olfactory and respiratory epithelium. In “The fine structure of the VNO in man,” however, it says some human VNO cells resemble cells in the rat VNO’s nonsensory epithelium. The broader claim that the lining is unlike VNO epithelium in other species is therefore not fully supported. (LLM, conf=0.83)

What the sources say

In “Does the human VNO contain sensory receptors?” (page unavailable), the paper says human VNO cells are not ultrastructurally identical to sensory neurons described in other mammals. “The fine structure of the human VNO” distinguishes a ciliated cell from those in typical respiratory epithelium. But “The fine structure of the VNO in man” says human VNO cells resemble cells in the nonsensory VNO epithelium of mammals such as rats, so the claimed difference from nonsensory epithelium is not supported.

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.
A language model drew the claims from the paper on 2026-10-11, under version 3 of the claim definition (model deepseek-v4.1-flash, prompt extract-v3).
A second model labelled each claim on 2026-10-11 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).
Cited sources are checked with a language model’s help (gpt-6-sol).
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.
