BACKGROUND: Almost 50% of patients with germ-cell tumors (GCT) are subfertile, and every step of the treatment may further impair fertility. As a result, sperm banking is often advised prior to radical orchiectomy. However, whether affected testes contribute to fertility is unclear.
OBJECTIVES: To determine whether maximal tumor diameter (MTD) is correlated with ipsilateral fertility (IF) in patients treated for GCT.
METHODS: We reviewed medical charts for demographic and clinical data of patients with GCT who had undergone orchiectomy at our institution between 1999 and 2015. The extent of spermatogenesis was categorized into three groups: full spermatogenesis, hypospermatogenesis, and absence of spermatogenesis. The presence of mature spermatozoa in the epididymis tail was also assessed. We defined IF as the combination of full spermatogenesis in more than 100 tubules and the presence of mature spermatozoa in the epididymis tail. Mann-Whitney was applied to determine the correlation between MTD and IF.
RESULTS: Of 57 patients, IF was present in 28 (49%). Mean patient age was 32.8 years in patients with positive IF and 33.4 years those with negative IF. Seminoma was diagnosed in 46.4% of patients with positive IF and in 65.5% of patients with negative IF. Full spermatogenesis was observed in 33 patients (57.8%). In 48 (82.7%), mature epididymal spermatozoa were found. No correlation was found between MTD and IF.
CONCLUSIONS: IF is present in almost half of the patients undergoing radical orchiectomy. Because IF cannot be predicted by MTD, routine pre-orchiectomy sperm banking is suggested.
