ABSTRACT
We report a case of male infertility secondary to pituitary apoplexy, which occurred as a sequela of korean hemorrhagic fever. A 32 years old male patient with past history of korean hemorrhagic fever was studied because of infertility and erectile impotence. The size of his testicles were about 8ml in Rt. and Lt. Semen analysis, endocrinologic studies, and brain MRI demonstrated hypogonadotrophic hypogonadism due to panhypopituitarism. The patient was treated with HCG (2,000 IU) administered intramuscularly three times per week for 6 months. After the treatment, improvement of male secondary sex characteristics such as hair growth and testicle size was noted. Promotion of sexual potency and improvement of semen quality were also noted. Following the treatment, his wife conceived after 6 months.
