- Summary: We investigated if bone mineral density was related to testosterone deficiency and/or previous cancer treatment in men who were childhood cancer survivors. Men with untreated testosterone deficiency or previous treatment with cranial irradiation were at increased risk of impaired bone health. Prevention of osteoporosis should be considered in their follow-up. Introduction: Childhood cancer survivors (CCS) are at increased risk of hypogonadism. Reduced bone mineral density (BMD) has been reported in CCS but it is unclear whether this is due to hypogonadism or a direct effect of cancer therapy. This study investigated BMD in CCS, and association with hypogonadism, previous treatment and cancer type. Methods: Investigation of 125 CCS (median age 33.7 at inclusion; 9.6 at diagnosis) and 125 age-matched population controls. Serum testosterone and luteinizing hormone were assayed and BMD at total hip and lumbar spine L1–L4 measured. The mean difference in BMD (g/cm2; 95% CI) between CCS and controls was analysed. Odds ratios (OR; 95% CI) for low BMD were also calculated. Results: Overall, BMD in the CCS cohort did not significantly differ from controls. However, compared with eugonadal CCS, the CCS with untreated hypogonadism had lower BMD at the hip (mean difference − 0.139 (− 0.210; − 0.067); p < 0.001) and spine (− 0.102 (− 0.174; − 0.030); p = 0.006). They also had a higher risk of low hip BMD (OR 4.1 (1.3; 14); p = 0.018). CCS treated with cranial irradiation also had lower BMD (hip − 0.076 (− 0.133; − 0.019); p = 0.009; spine − 0.071 (− 0.124; − 0.018); p = 0.009) compared with controls. The latter associations remained statistically significant after adjustment for hypogonadism. Conclusions: CCS with hypogonadism or previously treated with cranial irradiation are at increased risk of impaired bone health. Prevention of osteoporosis should be considered as an important part in future follow-up of these men.

- Background: This case control study aimed to investigate whether symptoms of sexual dysfunction are more common in males from infertile couples than in the general population and to explore whether symptoms of sexual dysfunction are associated to hypogonadism. Objectives: Participants were 165 subfertile men in infertile heterosexual relationships, 18–50 years of age, with sperm concentrations < 15 × 106/mL. The controls were 199 men from a population-based group, matched for age. Material and methods: Logistic regression was applied in order to calculate odds ratios (ORs) for seven different symptoms of sexual dysfunction. In a multivariate model, we tested independent effects of infertility and primary as well as secondary hypogonadism. Results: Statistically significant association between subfertility and symptoms of sexual dysfunction was found for lack of ability to control ejaculation (OR 2.2, 95% CI: 1.2–4.2). For hypogonadism, statistical significance was seen both in relation to low sexual interest/desire for sex (OR 2.3, 95% CI: 1.0–5.5) and for being worried about the size or shape of the penis (OR 3.6, 95% CI: 1.3–9.5). These associations remained statistically significant in males with primary but not those with secondary hypogonadism. Discussion: Our study showed that men from infertile couples have an increased risk of symptoms of sexual dysfunction and this risk is linked to androgen deficiency. Conclusion: Assessment of reproductive hormone levels and sexual function should routinely be done in this group of males.
