Diabetes in sex offenders

Thirteen diabetic male sex offenders were compared to 13 nondiabetic sex offenders matched on age, education and offense type. A standard battery of tests administered in the assessment of sex offenders was used to compare the two groups. The tests examine sexual history and preference, substance abuse, violence, personality, and neuropsychological impairment. Results showed that diabetics more often than controls complained of impotence and were nonresponders during phallometric testing. Diabetics, as adults, tended to have less sexual experience with adults and more with pubescent females. The two groups did not differ in number of sexual or nonsexual offenses. The diabetics reported more problems controlling their emotions and more often than controls presented in assessment with inappropriate and/or aggressive behavior and poor cooperation. MMPI results showed diabetics to have more overall clinical disturbance than controls including anxiety, health concerns, family problems, authority problems, criminality, confused thinking and ruminating. Diabetics and controls did not differ in reported frequency of violent behavior but the diabetics responded more extremely, given the circumstances. Diabetics tended to show more violence to their own children. The role of diabetes in the relapse cycle model of offending is discussed.     

A double blind trial of sex drive reducing medication in pedophiles

A sample of 100 men accused of sexual assault on a child and referred to a forensic clinic were approached for assessment and treatment in a double blind study of MPA (Provera). A total of 48 men completed assessment and 18 agreed to participate in the drug trial. Only 11 completed a 3-month course of MPA or placebo therapy. Those refusing treatment were less intelligent and less impaired on the Luria-Nebraska Neuropsychological Test Battery but were more impaired on the Halstead-Reitan Neuropsychological Test Battery. Dropouts differed only in reporting more frequent sexual fantasies of children. Of a possible 27 side effects for MPA, only two were statistically significant. MPA led to more depression and excess salivation than did the placebo, although the frequency of fatigue was noteworthy. MPA appeared as a useful sex drive reducing medication with few side effects but compliance in taking the drug was seen as a major obstacle in its use with pedophiles.     

Personality and sexual anomalies

Test properties of the Millon Clinical Multiaxial Inventory (MCMI) were examined in a sample of 419 sex offenders and controls in three different settings. The offender group included sexual aggressives, pedophiles, incest perpetrators and miscellaneous cases. Nineteen of the 20 scales of the MCMI had alpha reliability over 0.60 and for 13 scales it was over 0.80. The scales showed satisfactory discriminant validity from age but 9 scales showed a moderate influence of intelligence scores and education. Criminal history did not influence scale results. The scales unfortunately did show significant correlations with MMPI validity scales. Although the scales were not susceptible to naive lying, they were influenced by social desirability especially. Four factors were extracted in principal axes factor analysis that accounted for 91.2% of the total variance. The first factor explained 58.2% of the variance and was labeled general psychopathology. The other three factors suggested psychotic tendencies, extraversion and the bipolar dependency-antisocial tendencies. When the groups were compared, almost all scales significantly differentiated them. When the MMPI F-K Scale was forced to enter a stepwise discriminant analysis first, five scales still were significant; Narcissistic, Schizoid-Asocial, Alcohol Abuse, Paranoid, & Dependent-Submissive scales. The MCMI taps important dimensions in sex offenders but suffers from validity problems.     

Characteristics of sex offenders who were sexually victimized as children

From a data bank of 479 sex offenders, a comparison was undertaken of those reporting any childhood sexual abuse versus those reporting none. A total of 201 men (42.0%) reported abuse, 261 (54.5%) did not and for 17 (3.5%), information was unavailable. The Abused and Nonabused Groups were compared on demographic information, the MMPI, Clarke Sex History Questionnaire and the Clarke Parent Child Relations Questionnaire. The Abused and Nonabused groups were similar in age, marital status, income, and criminal history, but the Abused Group had significantly less education. The Abused Group showed sexualization of their childhood, not only in the number of contacts with adults but also with age peers and siblings of both sexes. They tended to have wider ranging and more frequent sexual experiences as adults both with men and women. They more often raped. The Abused Group tended to show more emotional instability than the Nonabused Group in more frequent suicidal ideation and suicide attempts, as well as in elevated Mania Scale Scores on the MMPI. The family background of the Abused Group was more disturbed than the Nonabused Group's; especially father-son relations. They reported more alcohol use and abuse in their parents and more parent-child aggression than nonabused offenders did. Although it is unlikely that child sexual abuse causes sexual anomalies, the results of the present study suggest that childhood sexual victimization in the lives of adult sex offenders merits further investigation and has implications for treatment.     

Induced luteolysis in the primate: rapid loss of luteinizing hormone receptors

The molecular mechanisms involved in luteolysis are still unclear in the primate. This study aimed to investigate the effect of induced luteolysis on the ovarian luteinizing hormone (LH) receptor and the steroidogenic enzyme, 3beta-hydroxysteroid dehydrogenase (3beta-HSD) in the marmoset monkey. Luteolysis was induced in the mid-luteal phase either directly by systemic prostaglandin F2alpha (PGF2alpha), or indirectly by LH withdrawal using systemic gonadotrophin releasing hormone antagonist (GnRHant) treatment. The LH receptor was studied by isotopic mRNA in-situ hybridization and in-situ ligand binding and 3beta-HSD expression was studied using isotopic mRNA in-situ hybridization and immunohistochemistry. Induced luteolysis was associated with a reduction in the expression of LH receptor (P < 0.0001) and 3beta-HSD mRNA, closely followed by a reduction in the LH receptor (P < 0.05) and 3beta-HSD protein concentrations within 24 h. There were no differences in the findings whether luteolysis was induced with PGF2alpha or GnRHant. This study shows that disparate mechanisms to induce luteolysis in the primate result in an identical rapid loss of the LH receptor and 3beta-HSD. In conclusion, induced luteolysis leads to rapid loss of the steroidogenic pathway in luteal cells.      

Semen parameters and testicular pathology in men with testicular cancer and contralateral carcinoma in situ or bilateral testicular malignancies

We evaluated 14 patients with bilateral testicular tumour, one-sided tumour and contralateral carcinoma in situ (CIS) of the testis or testis tumour in single testis with respect to their fertility. We analysed semen parameters, serum hormones [follicle-stimulating hormone (FSH), luteinizing hormone (LH) and testosterone], testicular sonography, testicular volumes and testicular histology prior to further anti-cancer treatment. Ten out of 14 patients showed normal or reduced sperm concentrations, while 4/14 patients were azoospermic. Serum FSH levels showed a significant negative correlation with sperm concentrations in patients with testicular malignancies (r = -0.64, P = 0.025). Testicular volumes revealed a significant positive correlation with semen parameters in patients with testes that were affected by CIS (r = 0.733, P = 0.038). We conclude that even bilateral testicular cancer and/or CIS do not preclude fertility and, therefore, patients should be offered andrological investigation and therapy, including possibly surveillance strategy or the chance for cryopreservation of the semen prior to further treatment in order to preserve their chances for paternity.
