Despite a publicly funded, universal healthcare system with equity as a stated health policy aim, utilization of PRT in Norway is significantly associated with factors such as household income and availability of radiotherapy facility at the diagnosing hospital. Even after adjustments for relevant factors, unexplained geographic variations in PRT utilization exist.
Sperm analysis and serum hormone measurements (LH, FSH, testosterone) were performed in 29 patients after orchiectomy for seminoma before and after irradiation. Before radiotherapy 14 of 20 orchiectomized patients were azoospermic or had impaired spermatogenesis. A minimum sperm count was found 1 year after radiotherapy with gradual improvement up to 2 years. The recovery of sperm cell production was impaired most in patients with pre-treatment sperm counts less than 3 million/ml. Serum testosterone remained at low normal levels throughout the observation period. The mean serum FSH was increased 1 year after radiotherapy but returned to normal in 50% of patients within 3 years after treatment. This post-treatment increase in FSH was significantly correlated with increased pre-treatment FSH but not with the gonadal dose, which was 1 to 3% of the target dose. Severe disturbances in spermatogenesis, observed 2 to 3 years after radiotherapy for early seminoma, are likely to be the expression of a highly impaired pre-treatment sperm cell production and only to a lesser degree dependent on the irradiation of the remaining testicle.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
