Unclear: information regarding allocation concealment is not known or not clearly presented. The method of allocation concealment was not reported in any study included within this review; however personal communications with one author, Huckercaused us to reassess the risk of bias as low as the investigator recalled remote assignment made by the pharmacist involved.

Cooper reported using a placebo pill described as "identical" to the active interventionwhich would guarantee blinding of participants; we assessed the risk of bias of this study and of Hucker within the context of this review as 'low'.

Study characteristics We found seven randomised trials involving participants, which provided data on Of the 24 patients that met this criteria, three "relapsed" with anomalous behaviour; two of these had been treated with MPA alone and one with imaginal desensitisation alone.

In terms of hormone profiles, measurement anomalies meant half of the prolactin data were unavailable for one study Bradford Seven of these men were described as presenting with severe sexual acting out resulting in social and legal implications, some of whom were facing trial.

This has two significant consequences for the design of trials and their interpretation. If such a relationship is identified, we will examine the clinical diversity of the studies as a possible explanation Egger

The plasma concentration of gonadal hormones was assayed from blood samples acquired via cardiac puncture from all rats immediately after CO 2 asphyxiation in order to ensure the efficacy of the hormonal manipulations. Gonadal hormones and sex differences in pain reactivity.

  • Some researchers see sex differences in adults as the direct result of organizational or activational effects of sex hormones, i.e., effects of sex hormones on the brain that occur either during fetal development or later in life (e.g., Kelly et al., ).Cited by: 2. Gonadal steroid hormones exert permanent organisational effects on the developing brain and thereby direct adult hormonal responsiveness to dictate sex-specific behaviour and physiology.
