Sexual health and treatment-related sexual dysfunction in sexual and gender minorities with prostate cancer

Abstract

Prostate cancer treatment has substantial effects on sexual health and function. Sexual function is a vital aspect of human health and a critical component of cancer survivorship, and understanding the potential effects of different treatment modalities on sexual health is crucial. Existing research has extensively described the effects of treatment on male erectile tissues necessary for heterosexual intercourse; however, evidence regarding their effects on sexual health and function in sexual and gender minority populations is minimal. These groups include sexual minority — gay and bisexual — men, and transgender women or trans feminine people in general. Such unique effects in these groups might include altered sexual function in relation to receptive anal and neovaginal intercourse and changes to patients’ role-in-sex. Sexual dysfunctions following prostate cancer treatment affecting quality of life in sexual minority men include climacturia, anejaculation, decreased penile length, erectile dysfunction, and problematic receptive anal intercourse, including anodyspareunia and altered pleasurable sensation. Notably, clinical trials investigating sexual outcomes after prostate cancer treatment do not collect sexual orientation and gender identity demographic data or outcomes specific to members of these populations, which perpetuates the uncertainty regarding optimal management. Providing clinicians with a solid evidence base is essential to communicate recommendations and tailor interventions for sexual and gender minority patients with prostate cancer.

Key points

  • Pleasurable receptive anal and neovaginal intercourse occur through the stimulation of the prostate, surrounding pelvic anatomy, and supplying neurovasculature, including branches of the pudendal, pelvic splanchnic and hypogastric nerves.

  • Sexual dysfunctions following prostate cancer treatment experienced by sexual minority men (SMM) include problematic receptive anal intercourse, erectile dysfunction, climacturia, anejaculation, decreased penile length, and changes in orgasm.

  • SMM with prostate cancer should be counselled regarding different treatment-related toxicities depending on their role-in-sex (top, bottom, versatile, side).

  • Anal dilators (to assist with receptive anal intercourse), vacuum pumps (to induce stronger erections for insertive intercourse) and penile constriction rings (to manage climacturia) should be discussed with SMM.

  • Gender minorities with prostate cancer are a heterogeneous cohort with a range of anatomy and hormonal milieu, requiring a nuanced and detailed conversation when discussing treatment options and relevant toxicities.

  • Consultations about prostate cancer with sexual and gender minorities should include counselling on the resumption of receptive anal intercourse, condom use, HIV pre-exposure prophylaxis and anal douching.
