Effect of Testosterone Replacement Therapy on Quality of Life and Sexual Function in Testicular Cancer Survivors with Mild Leydig Cell Insufficiency: Results from a Randomized Double-Blind Trial - Beyond the Abstract

Testicular cancer (TC) is one of the most curable cancers nowadays, with a 5-year survival rate of 97,3% in Europe,1 but several long-term complications have been related to the treatment.Approximately 50% of patients have disease confined to the testicle and will be cured with unilateral orchiectomy alone, while the remaining 50% will need additional cisplatin-based chemotherapy or abdominal radiotherapy, because of disease spread.3

The pituitary gland excretes luteinizing hormone (LH) and follicle stimulating hormone (FSH) in response to gonadotropin releasing hormone (GnRH) from the hypothalamus. LH stimulates the production of testosterone from Leydig cells in the testicles.4

Post orchiectomy, a great proportion of TC survivors develop mild Leydig cell insufficiency, which means they are in a compensated state with elevated LH and borderline low levels of s-testosterone.5 Furthermore, the toxic effects of radiotherapy and chemotherapy will reduce the Leydig cell function and contribute to a reduction in testosterone production too,with the risk appearing to be highest in the most heavily treated patients.7

In non-cancerous populations, testosterone deficiency, defined as total testosterone below the normal range, is associated with a higher incidence of fatigue,8 depression,and impaired sexual function10  as well as several other illnesses.11-13 Testosterone replacement therapy (TRT) has shown a positive effect on these conditions.14,15 To our knowledge, only one other study has investigated this question16 why it’s still not clear if TRT has a similar effect in TC survivors with mild Leydig cell insufficiency.

This study is a randomized double blind clinical trial, investigating the effect of testosterone replacement therapy in 69 TC survivors over a 12-month period.

The primary aim was to evaluate the effect on metabolic health, which has been reported in a previous publication.17 In this article, we present the secondary findings on patient reported anxiety and depression, overall quality of life, fatigue, and sexual function among TC survivors with. There was no improvement in the patient reported outcomes, routine testosterone substitution in this patient group is not recommended, but the article contains recommendations for further investigation of this subject.
