ABSTRACT
Purpose:
To investigate the quality of emergency-collected semen samples aimed at sperm cryopreservation provided by adolescents and young adults (AYAs) presenting with cancer or nonmalignant diseases.Methods:
This is a prospective cohort study of postpubertal males referred for sperm cryopreservation who provided at least one semen sample for fertility preservation at the Reproductive Medicine Clinic of Karolinska University Hospital, Stockholm, Sweden, between January 2009 and January 2020. Sperm quality was assessed by total sperm count, concentration, and motility. Sperm quality by disease groups was compared with the reference population data of fertile men defined by the World Health Organization (WHO).Results:
Among the 1252 patients who provided samples for cryopreservation, 1063 had cancer and 189 had nonmalignant diseases. The most common malignant indications included testicular cancers (n = 501) and Hodgkin lymphoma (n = 102). Among those with nonmalignant disease, 35% (n = 66) had testicular disease. Sperm quality was significantly lower in all groups of patients with cancer compared with the reference population. In total, azoospermia was found in 8% of the patients with cancer, in 9% of those with nonmalignant testicular disease, and in 3% of the remaining men with nonmalignant disease.Conclusion:
Sperm quality in adult patients with cancer was significantly impaired compared with the WHO reference population standards for fertile men. For adolescent patients, standard reference values are lacking. AYAs wishing to preserve fertility should receive individualized counseling regarding sperm quality at the time of cryopreservation, and in selected cases, banking of additional samples should be recommended depending on the sperm quality parameters.
