Androgen Deprivation Therapy in Pedophilic Disorder: Exploring the Physical, Psychological, and Sexual Effects From a Patient's Perspective

BACKGROUND

The use of androgen deprivation therapy (ADT) shows promising results in the treatment of paraphilic disorders. Although the side effects of ADT can be intrusive, there is no research into the experiences of patients with pedophilic disorder themselves.

AIM

This research aims to explore the psychological, physical, and sexual experiences of ADT from the perspective of sex offenders diagnosed with pedophilic disorder.

METHODS

Twelve semistructured in-depth interviews with male adults diagnosed with pedophilic disorder were conducted using a phenomenological approach. Six of the 12 respondents were on luteinizing hormone-releasing hormone agonists and the remaining on anti-androgens. Half of each group were inpatients, and the other half outpatients. The respondents were recruited in collaboration with one psychiatric hospital. The data were analyzed with help of a qualitative software application NVivo.

OUTCOMES

The respondents described experiences on the use of ADT on a physical, psychological, and sexual level.

RESULTS

The most prominent physical side effects mentioned were bone loss, weight gain, and breast formation. The respondents generally described a positive influence of the medication on their well-being. They felt more relaxed and experienced a reduction in frequency and intensity of sexual fantasies, anger, and aggressive feelings in general. In addition, all the respondents noticed a lower frequency of sexual contact and masturbation. Most of the participants experienced the use of ADT as a mandatory decision made by the treating psychiatrist.

CLINICAL IMPLICATIONS

This study recommends informing patients and their loved ones on the potential side effects of ADT. Furthermore, training forensic counselors on potential side effects of ADT and methods to alleviate them can promote the dissemination of information and will encourage the informed consent procedure.

STRENGTHS & LIMITATIONS

This is the first qualitative study about the experiences of ADT in men diagnosed with pedophilic disorder in Belgium. Future studies should include more than one treatment center.

CONCLUSION

The majority of the participants had a positive attitude towards ADT in general. Boons L, Jeandarme I, Vervaeke G. Androgen Deprivation Therapy in Pedophilic Disorder: Exploring the Physical, Psychological, and Sexual Effects From a Patient's Perspective. J Sex Med 2021;18:353-362.

A Case of Paraphilia with Osteoporosis and Administered with Depot Leuprorelin

Paraphilia is a complex psychological and psychiatric disorder that has been difficult to treat. Leuprorelin has been used as one of the therapeutic methods for paraphilia. Leuprorelin administration could change insulin resistance and accelerate bone loss. The case study in this work was a 59-year-old man who visited a hospital with the chief complaints of frotteuristic behaviors in public places, a continuous increase in sexual desire, and sexual molestation behavior that started in 2007. We injected leuprorelin (3.6 mg) intramuscularly every month for this patient with paraphilia and comorbidities of osteoporosis and hyperthyroidism. The clinical global impression (CGI), Sex Addiction Screening Test (SAST), Wilson Sex Fantasy Questionnaire (WSFQ), physical examination, and laboratory tests were performed. After 12 months of leuprorelin injection for paraphilia, we found a significant improvement in abnormal sexual behavior/desire without aggravation of osteoporosis/hyperthyroidism. Gonadotrophin-Releasing Hormone (GnRH) analogs could be used as alternative or supplementary treatment methods for paraphilia with osteoporosis/hyperthyroidism.

Pharmacological treatment of patients with paraphilic disorders and risk of sexual offending: An international perspective

Objectives: The present study aims to evaluate existing policy and practice relating to the use of pharmacological treatments with patients suffering from paraphilic disorders who are at risk of committing further sexual offences.Methods: A systematic literature search was conducted to document current legal policies across 26 different countries. In addition, a questionnaire assessing the practice of pharmacological treatment was sent to practitioners involved in the treatment of patients with paraphilic disorders.Results: Legal policies concerning the preconditions of using pharmacological treatments differ considerably between countries, and for most jurisdictions do not exist. Drawing on the responses of 178 practitioners, pharmacological agents are a useful addition to psychotherapeutic interventions, especially with those patients classified as medium or high risk for sexually violent behaviours. It would appear that most patients are medically examined, are informed of the risks and possible side effects before treatment commences and are also obliged to sign a consent form.Conclusions: Although pharmacological agents can be seen as an intrusion into a patients' sexual self determination, results indicate that ethical and clinical standards are being met in the majority of cases. However, further promotion of current WFSBP treatment guidelines would help to standardise practice across North American and European countries.

Monitoring urinary testosterone and epitestosterone levels, and their ratio, in Korean chemical castration subjects using liquid chromatography–tandem mass spectrometry

In Europe, chemical castration has been adopted as a treatment for paraphilia since the 1930s. Among the various chemical castration agents, luteinizing hormone-releasing hormone (LHRH) agonists are now used widely because of their effectiveness and safety. In South Korea, a legislation of chemical castration to control the sexual impulses of sexual offenders was enforced in July 2011. Most of these subjects are treated with leuprorelin acetate, an LHRH agonist, for chemical castration. Despite this, there are few studies that address the long-term influence of LHRH agonists on testosterone (T) and epitestosterone (E) levels in chemical castration subjects. In order to analyze the urinary levels of T in chemical castration subjects, whose T levels are extremely low, we developed and validated an analytical method for the detection of both T and E in human urine using a liquid chromatography-tandem mass spectrometry (LC–MS/MS) system. The urine samples were hydrolyzed, extracted, and analyzed by LC–MS/MS with electrospray ionization in the positive-ion mode. The limits of detection were 0.02 ng/mL and the limits of quantitation were 0.05 ng/mL, which provided great sensitivity. The established method was applied to urine samples from chemical castration subjects and healthy male volunteers. The chemical castration subjects showed significantly lower urinary T levels than the control subjects. In addition, the urinary E levels were also lower in the chemical castration subjects; however, the T/E ratios were constant and did not show a notable decrease because of the simultaneous decrease in both urinary T and E. The urinary T levels and T/E ratio did not exceed the doping control criteria for exogenous T ingestion for any subject. This study shows the trend of urinary T and E levels in long-term treated chemical castration subjects by establishing a highly sensitive LC–MS/MS method, that provides useful information for monitoring chemical castration.

Paraphilias

PURPOSE OF REVIEW

The concept of paraphilia still carries an 'unwanted burden' of sexual norms because the pathologization of some sexual practices as paraphilic disorders is still based on the assumption that normal sexuality should be genitally organized with the aim of reproduction. The aim of this review is to give an impression of the ongoing discussion about the changes introduced with the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) and the results of recent research in this area.

RECENT FINDINGS

The release of DSM-5 in the spring of 2013 introduced a distinction between paraphilias and paraphilic disorders, implying a destigmatization of consenting adults engaging in unusual sexual behaviour. According to DSM-5 diagnostic criteria, paedophilic disorder is the only paraphilic disorder without an 'in remission' and an 'in a controlled environment' specifier. Today, antiandrogen treatment is offered to sex offenders in many countries as an additional treatment strategy alongside psychotherapy.

SUMMARY

The introduction of DSM-5 offers the possibility to distinguish between paraphilia and paraphilic disorders. The aetiology of paraphilias is still unknown. Paraphilias are much more common in men than in women, but the reasons for this difference remain unknown. So far there is no clear consent on the best therapeutic approach for a paraphilic disorder.

Pharmacological interventions for those who have sexually offended or are at risk of offending

BACKGROUND

Sexual offending is a serious social problem, a public health issue, and a major challenge for social policy. Victim surveys indicate high incidence and prevalence levels and it is accepted that there is a high proportion of hidden sexual victimisation. Surveys report high levels of psychiatric morbidity in survivors of sexual offences.Biological treatments of sex offenders include antilibidinal medication, comprising hormonal drugs that have a testosterone-suppressing effect, and non-hormonal drugs that affect libido through other mechanisms. The three main classes of testosterone-suppressing drugs in current use are progestogens, antiandrogens, and gonadotropin-releasing hormone (GnRH) analogues. Medications that affect libido through other means include antipsychotics and serotonergic antidepressants (SSRIs).

OBJECTIVES

To evaluate the effects of pharmacological interventions on target sexual behaviour for people who have been convicted or are at risk of sexual offending.

SEARCH METHODS

We searched CENTRAL (2014, Issue 7), Ovid MEDLINE, EMBASE, and 15 other databases in July 2014. We also searched two trials registers and requested details of unidentified, unpublished, or ongoing studies from investigators and other experts.

SELECTION CRITERIA

Prospective controlled trials of antilibidinal medications taken by individuals for the purpose of preventing sexual offences, where the comparator group received a placebo, no treatment, or 'standard care', including psychological treatment.

DATA COLLECTION AND ANALYSIS

Pairs of authors, working independently, selected studies, extracted data, and assessed the risk of bias of included studies. We contacted study authors for additional information, including details of methods and outcome data.

MAIN RESULTS

We included seven studies with a total of 138 participants, with data available for 123. Sample sizes ranged from 9 to 37. Judgements for categories of risk of bias varied: concerns were greatest regarding allocation concealment, blinding of outcome assessors, and incomplete outcome data (dropout rates in the five community-based studies ranged from 3% to 54% and results were usually analysed on a per protocol basis).Participant characteristics in the seven studies were heterogeneous, but the vast majority had convictions for sexual offences, ranging from exhibitionism to rape and child molestation.Six studies examined the effectiveness of three testosterone-suppressing drugs: cyproterone acetate (CPA), ethinyl oestradiol (EO), and medroxyprogesterone acetate (MPA); a seventh evaluated two antipsychotics (benperidol and chlorpromazine). Five studies were placebo-controlled; in two, MPA was administered as an adjunctive treatment to a psychological therapy (assertiveness training or imaginal desensitisation). Meta-analysis was not possible due to heterogeneity of interventions, comparators, study designs, and other issues. The quality of the evidence overall was poor. In addition to methodological issues, much evidence was indirect.

PRIMARY OUTCOME

recividism. Two studies reported recidivism rates formally. One trial of intramuscular MPA plus imaginal desensitisation (ID) found no reports of recividism at two-year follow-up for the intervention group (n = 10 versus one relapse within the group treated by ID alone). A three-armed trial of oral MPA, alone or in combination with psychological treatment, reported a 20% rate of recidivism amongst those in the combined treatment arm (n = 15) and 50% of those in the psychological treatment only group (n = 12). Notably, all those in the 'oral MPA only' arm of this study (n = 5) dropped out immediately, despite treatment being court mandated.Two studies did not report recidivism rates as they both took place in one secure psychiatric facility from which no participant was discharged during the study, whilst another three studies did not appear directly to measure recividism but rather abnormal sexual activity alone.

SECONDARY OUTCOMES

The included studies report a variety of secondary outcomes. Results suggest that the frequency of self reported deviant sexual fantasies may be reduced by testosterone-suppressing drugs, but not the deviancy itself (three studies). Where measured, hormonal levels, particularly levels of testosterone, tended to correlate with measures of sexual activity and with anxiety (two studies). One study measured anxiety formally; one study measured anger or aggression. Adverse events: Six studies provided information on adverse events. No study tested the effects of testosterone-suppressing drugs beyond six to eight months and the cross-over design of some studies may obscure matters (given the 'rebound effect' of some hormonal treatments). Considerable weight gain was reported in two trials of oral MPA and CPA. Side effects of intramuscular MPA led to discontinuation in some participants after three to five injections (the nature of these side effects was not described). Notable increases in depression and excess salivation were reported in one trial of oral MPA. The most severe side effects (extra-pyramidal movement disorders and drowsiness) were reported in a trial of antipsychotic medication for the 12 participants in the study. No deaths or suicide attempts were reported in any study. The latter is important given the association between antilibidinal hormonal medication and mood changes.

AUTHORS' CONCLUSIONS

We found only seven small trials (all published more than 20 years ago) that examined the effects of a limited number of drugs. Investigators reported issues around acceptance and adherence to treatment. We found no studies of the newer drugs currently in use, particularly SSRIs or GnRH analogues. Although there were some encouraging findings in this review, their limitations do not allow firm conclusions to be drawn regarding pharmacological intervention as an effective intervention for reducing sexual offending.The tolerability, even of the testosterone-suppressing drugs, was uncertain given that all studies were small (and therefore underpowered to assess adverse effects) and of limited duration, which is not consistent with current routine clinical practice. Further research is required before it is demonstrated that their administration reduces sexual recidivism and that tolerability is maintained.It is a concern that, despite treatment being mandated in many jurisdictions, evidence for the effectiveness of pharmacological interventions is so sparse and that no RCTs appear to have been published in two decades. New studies are therefore needed and should include trials with larger sample sizes, of longer duration, evaluating newer medications, and with results stratified according to category of sexual offenders. It is important that data are collected on the characteristics of those who refuse and those who drop out, as well as those who complete treatment.

Assessment methods and management of hypersexuality and paraphilic disorders

PURPOSE OF REVIEW

The recent implementation of the Diagnostic and Statistical Manual of Mental Disorders, fifth edition introduced some important changes in the conceptualization of hypersexuality and paraphilic disorders. The destigmatization of nonnormative sexual behaviors could be viewed as positive, However, other changes are more controversial. In order to stimulate new research approaches and provide mental healthcare providers with appropriate treatment regimes, validated assessment and treatment methods are needed. The purpose of this article is to review the studies published between January 2013 and July 2014 that aimed at assessing the psychometric properties of the currently applied assessment instruments and treatment approaches for hypersexuality and hypersexual disorders or paraphilias and paraphilic disorder.

RECENT FINDINGS

Currently existing instruments can validly assess hypersexual behaviors in different populations (e.g. college students, gay and bisexual men, and patients with neurodegenerative disorders) and cultural backgrounds (e.g. Germany, Spain, and USA). Concerning the assessment of paraphilias, it was shown that combining different assessment methods show a better performance in distinguishing between patients with paraphilias and control groups. In addition to psychotherapeutic treatment, pharmacological agents aiming at a reduction of serum testosterone levels are used for hypersexual behaviors as well as paraphilic disorders.

SUMMARY

Although the currently applied assessment and treatment methods seem to perform quite well, more research about the assessment and evidence-based treatment is needed. This would help to overcome the existing unresolved issues concerning the conceptualization of hypersexual and paraphilic disorders.
