Post-treatment fertility in patients with testicular cancer. II. Influence of cis-platin-based combination chemotherapy and of retroperitoneal surgery on hormone and sperm cell production

Abstract

Active sperm production was observed in 20 of 35 patients with testicular cancer 1 year after discontinuation of all treatment (retroperitoneal surgery only: 13; cis-platin-based chemotherapy (CVB) +/- other treatment: 22). The percentage of patients who regained spermatogenesis increased slightly after a further 1 to 2 years. Fourteen patients (of 121 under observation) impregnated their wives (after retroperitoneal surgery: 9; after CVB +/- other therapy: 5). The individual serum FSH values correlated significantly with the results of sperm analysis: an FSH value greater than or equal to 20 iu/l indicated azoospermia in 8 of 12 patients, whereas only 5 of 30 patients with FSH levels less than or equal to 12 iu/l were azoospermic. Serum testosterone and pituitary serum LH were virtually unaffected by the treatment. In conclusion, 1 to 3 years after cis-platin-based multi-modality treatment for testicular cancer, 50 to 60% of patients have active spermatogenesis and fatherhood can be achieved by a significant number of them.
