- In this study, preoperative radiotherapy for rectal cancer was found to result in a dose-dependent impairment of spermatogenesis and Sertoli cell function, reflected both by decreased sperm count and characteristic changes in hormonal response, with signs of partial recovery between 12 and 24 months after surgery. Decreased semen volume was also observed, indicating ejaculatory tract dysfunction, that seemed to be longer-lasting and not related to testicular dose. This threatens fertility in men treated for rectal cancer, and suggests that pretreatment cryopreservation and anticonception after treatment should be discussed individually.

Journal article (peer-reviewed)abstract
- BackgroundThe effect of risk-reducing salpingo-oophorectomy (RRSO) on breast cancer risk forBRCA1andBRCA2mutation carriers is uncertain. Retrospective analyses have suggested a protective effect but may be substantially biased. Prospective studies have had limited power, particularly forBRCA2mutation carriers. Further, previous studies have not considered the effect of RRSO in the context of natural menopause.MethodsA multi-centre prospective cohort of 2272BRCA1and 1605BRCA2mutation carriers was followed for a mean of 5.4 and 4.9 years, respectively; 426 women developed incident breast cancer. RRSO was modelled as a time-dependent covariate in Cox regression, and its effect assessed in premenopausal and postmenopausal women.ResultsThere was no association between RRSO and breast cancer forBRCA1(HR = 1.23; 95% CI 0.94–1.61) orBRCA2(HR = 0.88; 95% CI 0.62–1.24) mutation carriers. ForBRCA2mutation carriers, HRs were 0.68 (95% CI 0.40–1.15) and 1.07 (95% CI 0.69–1.64) for RRSO carried out before or after age 45 years, respectively. The HR forBRCA2mutation carriers decreased with increasing time since RRSO (HR = 0.51; 95% CI 0.26–0.99 for 5 years or longer after RRSO). Estimates for premenopausal women were similar.ConclusionWe found no evidence that RRSO reduces breast cancer risk forBRCA1mutation carriers. A potentially beneficial effect forBRCA2mutation carriers was observed, particularly after 5 years following RRSO. These results may inform counselling and management of carriers with respect to RRSO.

Effect of Gonadotropin-Releasing Hormone Antagonist on Risk of Committing Child Sexual Abuse in Men with Pedophilic Disorder: A Randomized Clinical Trial
- 2020
-
In: JAMA Psychiatry. - : American Medical Association (AMA). - 2168-622X .- 2168-6238. ; 77:9, s. 897-905

Journal article (peer-reviewed)abstract
- Importance: Evidence-based treatments from randomized clinical trials for pedophilic disorder are lacking. Objective: To determine whether a gonadotropin-releasing hormone antagonist reduces dynamic risk factors for committing child sexual abuse. Design, Setting, and Participants: This academically initiated, double-blind, placebo-controlled, parallel-group, phase 2 randomized clinical trial was conducted at the ANOVA center in Stockholm, Sweden, from March 1, 2016, to April 30, 2019. Individuals who contacted PrevenTell, the national telephone helpline for unwanted sexuality, were recruited. Eligible participants were men seeking help aged 18 to 66 years with a pedophilic disorder diagnosis and no contraindications to the intervention. The primary end point was assessed by intent-to-treat analysis. Interventions: Randomization to receive either 2 subcutaneous injections of 120 mg of degarelix acetate or equal volume of placebo. Main Outcomes and Measures: The primary end point was the mean change between baseline and 2 weeks in the composite risk score of 5 domains of child sexual abuse ranging from 0 to 15 points; each domain could be rated from 0 to 3 points. Secondary end points included efficacy at 2 and 10 weeks as measured by the composite score, each risk domain, quality of life, self-reported effects, and adverse events. Results: A total of 52 male participants (mean [SD] age, 36 [12] years) were randomized to receive either degarelix (n = 25; with 1 withdrawal) or placebo (n = 26). At 2 weeks, the composite risk score decreased from 7.4 to 4.4 for participants in the degarelix group and from 7.8 to 6.6 for the placebo group, a mean between-group difference of -1.8 (95% CI, -3.2 to -0.5; P =.01). A decrease was seen in the composite score at 10 weeks (-2.2 [95% CI, -3.6 to -0.7]) as well as in the domains of pedophilic disorder (2 weeks: -0.7 [95% CI, -1.4 to 0.0]; 10 weeks: -1.1 [95% CI, -1.8 to -0.4]) and sexual preoccupation (2 weeks: -0.7 [95% CI, -1.2 to -0.3]; 10 weeks: -0.8 [95% CI, -1.3 to -0.3]) in the degarelix group compared with the placebo group. No difference was seen for the domains of self-rated risk (2 weeks: -0.4 [95% CI, -0.9 to 0.1]; 10 weeks: -0.5 [95% CI, -1 to 0.0]), low empathy (2 weeks: 0.2 [95% CI, -0.3 to 0.6]; 10 weeks: 0.2 [95% CI, -0.2 to 0.6]), and impaired self-regulation (2 weeks: -0.0 [95% CI, -0.7 to 0.6]; 10 weeks: 0.1 [95% CI, -0.5 to 0.8]), or quality of life (EuroQol 5 Dimensions questionnaire index score, 2 weeks: 0.06 [95% CI, -0.00 to 0.12], and 10 weeks: 0.04; 95% CI, -0.02 to 0.10; EuroQol visual analog scale, 2 weeks: 0.6 [95% CI, -9.7 to 10.9], and 10 weeks: 4.2 [95% CI, -6.0 to 14.4]). Two hospitalizations occurred from increased suicidal ideation, and more injection site reactions (degarelix: 22 of 25 [88%]; placebo: 1 of 26 [4%]) and hepatobiliary enzyme level elevations were reported by participants who received degarelix (degarelix: 11 of 25 [44%]; placebo: 2 of 26 [8%]). Among the 26 participants randomized to receive degarelix, 20 (77%) experienced positive effects (eg, improved attitude or behavior) on sexuality and 23 (89%) reported adverse effects on the body. Conclusion and Relevance: This trial found that degarelix reduced the risk score for committing child sexual abuse in men with pedophilic disorder 2 weeks after initial injection, suggesting use of the drug as a rapid-onset treatment option. Further studies are warranted into the effects and long-term adverse effects of hormone deficiency.

Pharmacological Treatment for Pedophilic Disorder and Compulsive Sexual Behavior Disorder: A Review
- 2022
-
In: Drugs. - : Springer Science and Business Media LLC. - 0012-6667 .- 1179-1950. ; 82:6, s. 663-681

Journal article (peer-reviewed)abstract
- Guidelines for the pharmacological treatment of paraphilic disorders have historically been based on data from forensic settings and on risk levels for sexual crime. However, emerging treatment options are being evaluated for individuals experiencing distress because of their sexual urges and preferences, targeting both paraphilic disorders such as pedophilic disorder (PeD) and the new diagnosis of compulsive sexual behavior disorder (CSBD) included in the International Classification of Diseases, 11th Revision (ICD-11). As in other mental disorders, this may enable individualized pharmacological treatment plans, taking into account components of sexuality (e.g. high libido, compulsivity, anxiety-driven/sex as coping), medical and psychiatric comorbidity, adverse effects and patient preferences. In order to expand on previous reviews, we conducted a literature search focusing on randomized controlled trials of pharmacological treatment for persons likely to have PeD or CSBD. Our search was not restricted to studies involving forensic or criminal samples. Twelve studies conducted between 1974 and 2021 were identified regardless of setting (outpatient or inpatient), with only one study conducted during the last decade. Of a total of 213 participants included in these studies, 122 (57%) were likely to have PeD, 34 (16%) were likely to have a CSBD, and the remainder had unspecified paraphilias (40, 21%) or sexual offense (17, 8%) as the treatment indication. The diagnostic procedure for PeD and/or CSBD, as well as comorbid psychiatric symptoms, has been described in seven studies. The studies provide some empirical evidence that testosterone-lowering drugs reduce sexual activity for patients with PeD or CSBD, but the body of evidence is meager. There is a need for studies using larger samples, specific criteria for inclusion, longer follow-up periods, and standardized outcome measures with adherence to international reporting guidelines.
