Sexuality and fertility after cancer

Abstract

As more people achieve long-term survival after cancer, sexual dysfunction and infertility have increasingly been recognized as negative consequences that impact quality of life. Sexual dysfunction is a frequent long-term side effect of cancer treatment, but damage to different underlying physiological systems is salient in men versus women. Men frequently have erectile dysfunction (ED) related to damage to the autonomic nervous system and/or reduced circulation of blood to the penis. Hormonal impairment of sexual function is less common. Women, in contrast, are able to overcome damage to autonomic nerves if genital tissues remain structurally intact and estrogenized. Female sexual dysfunction is frequently associated with sudden premature ovarian failure or direct effects of radiation fibrosis or scar tissue causing pain with sexual activity. The lack of validated interventions for sexual rehabilitation after cancer is a major problem, as is finding cost-effective ways of providing services. Concerns about fertility are also a major source of distress to people treated for cancer during childhood or young adulthood, yet many young survivors do not recall any discussion about future childbearing potential with their oncology team. Since fertility preservation is becoming more practical for both men and women, producing patient and professional educational materials and developing professional practice guidelines should be high priorities for oncology societies.
