Abstract

Removal of the vomeronasal organ eliminated androgen surges in male hamsters in response to female vaginal secretions in both sexually experienced and sexually naive males; lesions of the olfactory mucosa had no effect on such responses. Both lesions led to deficits in behavioral responses to vaginal secretions. In response to interactions with estrous females, in contrast, lesions of either system alone had no influence on androgen surges in males (either sexually experienced or naive). Lesions of both systems, however, eliminated androgen surges in sexually naive males but not sexually experienced males. These dual lesions eliminated male mating behavior, while lesions of either system alone had little influence on mating. There were no significant correlations in any experiment between level of behavioral responses and degree of change in androgen levels. Thus, we conclude that the vomeronasal system mediates androgen surges in response to female odors but is not necessary for such responses to females themselves. In sexually naive males the vomeronasal and olfactory systems together are necessary for androgen responses to females. Behavioral responses were influenced by lesions and by sexual experience. Lesions of both systems increased the latency to investigate vaginal secretions, and sexual experience decreased the latency and increased the duration of investigation. Lesions and experience also influenced male sexual performance.

  • 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.

    “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).”

    From Human Vomeronasal Organ Function: A Critical Review of Best and Worst Cases (2001) · cites this paper as Pfeiffer and Johnston, 1994

    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)

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.
