A qualitative study exploring men's experience of sexual dysfunction as a result of radiotherapy and androgen deprivation therapy to treat prostate cancer

Aim: Sexual dysfunction is a common side effect of external beam radiotherapy (EBRT) and androgen deprivation therapy (ADT) to treat prostate cancer. Men are likely to experience erectile dysfunction, low libido, ejaculatory problems and penile shortening. This qualitative study explored men's perceptions of sexual dysfunction, including factors such as self-perception, relationships and information and support needs. Methods: Semi-structured interviews were carried out with n = 8 men living 18-30 months after EBRT +/- ADT. The interviews were transcribed and thematic analysis was carried out. Results: All men experienced sexual dysfunction following treatment. The main themes arising were: (i) priorities-sexual issues were not a priority when making treatment decisions, (ii) information and support-men described a lack of information and support about sexual dysfunction and (iii) impact-sexual dysfunction impacted on their self-perception and relationships. Findings: Men undergoing EBRT/ADT for prostate cancer may be affected by post-treatment changes in sexual function in a range of ways. This study suggests that they would benefit from early and wide-ranging information and support on sexual dysfunction, even if they do not consider it as a priority. Candid discussions about self-perception and relationships, as well as physical changes, may equip them to cope with post-treatment changes.
