Semen quality and hormonal status of patients following testicular torsion.

16 patients, 4 months to five years following unilateral torsion of the testis were evaluated as to semen quality and hormonal status. In patients operated within 12 hours of the onset of pain 44% had normal semen quality while in those operated following more than 12 hours only 20% had normal semen analysis. FSH, LH and testosterone levels were normal in 14 of the 16 patients. One patient had a low testosterone level and slightly elevated FSH, another patient had slightly elevated levels of both FSH and LH.
