Sperm quality before treatment in patients with early stage Hodgkin's lymphoma enrolled in EORTC-GELA Lymphoma Group trials

Abstract

Background: Although widely recommended, cryopreservation of sperm is sometimes not performed for patients with Hodgkin's lymphoma because of presumed poor sperm quality related to the disease. We investigated sperm quality and factors determining it in untreated patients with early stage Hodgkin's lymphoma.

Design and methods: Of 2362 males who participated in EORTC H6-H9 trials, 474 (20%) had data available. Sperm quality was defined according to World Health Organization guidelines. Determining factors were studied by logistic regression analysis.

Results: The median sperm concentration was 40x10(6)/mL (range, 0-345x10(6)/mL) and the median motility 50% (range, 0-90%). Sperm quality was good (concentration >or=20x10(6)/mL and motility >or=50%), intermediate (concentration >or=5x10(6)/mL) and poor (concentration <5x10(6)/mL but >0) in 41%, 49% and 7% of patients, respectively. Three percent of the patients were azoospermic. No relation was found between sperm quality and age or clinical stage of the Hodgkin's lymphoma, but B-symptoms and elevated erythrocyte sedimentation rate predicted poor sperm quality. The odds ratios for the association of poor sperm quality with the variables examined were: presence of B-symptoms, 2.77 (95% CI, 1.50-5.12; p=0.001); erythrocyte sedimentation rate of 50 mm/h or greater, 2.35 (95% CI, 1.24-4.43; p=0.009); fever, 3.22 (95% CI, 1.41-7.33; p=0.005), and night sweats, 3.78 (95% CI, 1.97-7.26; p<0.001). There was no relation between sperm quality and pre-treatment follicle stimulating hormone level.

Conclusions: In this large study of males with Hodgkin's lymphoma, 90% had good or intermediate sperm quality. Three percent were azoospermic. There was an association between sperm quality and the presence or absence of B-symptoms, in particular fever and night sweats. With modern fertilization techniques, in most patients with early-stage Hodgkin's lymphoma sperm quality before treatment is good enough for future fatherhood.

Figure 1.

Sperm quality and FSH level before treatment. Sperm quality was divided into three categories: good quality if concentration of spermatozoa was ≥20×10⁶/mL and motility ≥50%; poor quality if concentration of spermatozoa was <5×10⁶/mL; intermediate quality for all other concentrations, except azoospermia. First vertical reference line: sperm concentration: 5×10⁶/mL. Second vertical reference line: sperm concentration: 20×10⁶/mL. Horizontal reference line: FSH: upper normal value; values above this line indicate elevated FSH and values below this line indicate non-elevated FSH. Two outliers are present; norm. FSH: normalized FSH.
