Semen analysis in testicular cancer and Hodgkin's disease: pre- and post-treatment findings and implications for cryopreservation.
Over a 7-year period, seminal analysis has been performed on 208 patients with testicular tumours, after orchiectomy, but before any other treatment. Only 22% of 54 patients with seminomas, and 29% of 154 patients with teratomas or mixed tumours, had sperm counts exceeding 10 million per ml. Very low sperm counts were observed in some patients who had previously fathered children. Post-treatment sperm counts were done in 117 patients, 80 of whom had received multiple drug chemotherapy: 42 of these men had pre- and post-treatment sperm counts. Overall, 24% of men receiving chemotherapy recovered sperm counts greater than 10 million per ml up to 3 years after therapy. Surprisingly, such recovery was seen in 35% of 23 men with initially poor sperm counts, but in only 26% of 19 with good initial counts. Only 27% of 49 patients with Hodgkin's disease had initial sperm counts of more than 10 million per ml; after chemotherapy only 1 of 29 patients recovered to this level. Only one quarter of these young men had semen which was adequate for cryopreservation. Artificial insemination with semen preserved in liquid nitrogen has been performed in 15 couples: 2 normal babies have been produced and a third pregnancy is progressing normally.
