Abstract

Objective To assess the degree to which sexual side effects (SSE) are associated with prolactin-raising antipsychotics, and to what degree such SSE are reducible to serum prolactin levels.Method A large sample (n=264) of patients treated for 6 weeks with prolactin-raising and prolactin-sparing antipsychotics was assessed for changes in sexual performance in terms of libido, arousal and orgasm using the Antipsychotics and Sexual Functioning Questionnaire. For men also erection and ejaculation were evaluated. At 6 weeks, prolactin levels were assessed and analyzed in relation to sexual performance.Results Men and women reported SSE (libido and orgasm) with about the same frequency. Prolactin-raising medication induced significantly more SSE than prolactin-sparing medication (adjusted OR=3.4, 95% CI: 1.8, 6.5) with 43% of emerging SSE attributable to prolactin-raising medication. When adjusted for serum prolactin, the association between prolactin-raising medication and SSE was reduced but remained significant (OR=2.1, 95% CI: 1.0, 4.5); 27% of emerging SSE remained attributable to prolactin-raising medication. For erectile and ejaculatory dysfunction in men, the attributable fraction due to prolactin-raising medication was 32% before, and 11% after adjustment for serum prolactin.Conclusions Around 40% of emerging SSE in schizophrenia are attributable to the prolactin-raising properties of antipsychotic medication. Of this attributable fraction, around one-third to two-thirds is directly reducible to the effects of serum prolactin.

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.
