Testicular cancer stage does not affect semen parameters, according to data from a retrospective study of 38 patients with testicular cancer. Semen parameters, cancer stage and tumour histology were collected from patients, who also underwent cryopreservation before orchiectomy. Abnormal semen parameters recorded in patients included azoospermia (11%), abnormally low semen volume (18%), abnormal total sperm count (47%) and abnormal motility percentage (24%). Semen parameters did not vary significantly between patients with stage I cancer and patients with stage II/III cancer, or between patients with seminoma and patients with non-seminomatous germ cell tumours. Additionally, no significant association was found between abnormal semen parameters and tumour histology or cancer stage.
