Sperm Count Improvement in a Cancer-Surviving Patient

OBJECTIVE: To describe the case of a cancer-surviving patient who was treated with an aromatase inhibitor for fertility reasons with successful results. CLINICAL CASE: A 30-year-old patient from our institute who had been submitted to bone marrow transplantation in the past as part of treatment for Hodgkin's disease had revealed oligospermia several times. His sperm count mean value was 33,500 cells/ml. He was treated with an aromatase inhibitor (letrozole, 2 mg/day) for 8 months. After this period, his sperm count had increased significantly to 1,000,000 cells/ml. CONCLUSION: A large number of cancer survivors express a wish for having babies. After their cure, a lot of them have a low count of spermatozoids, and we think that our results show an easy way of helping them.
