Serum levels of luteinizing hormone (LH) and follicle-stimulating hormone (FSH) were determined by radioimmunoassay in six subjects who were exposed accidentally to /sup 192/Ir gamma rays. All subjects showed normal levels of LH and FSH shortly after the irradiation. From 100 to 150 days post- irradiation, however, serum FSH levels increased in subjects who received 12.2 rad or more, a finding in agreement with the decrease in sperm concentration below 10 millions/ml, while in the other two subjects who received 9.8 and 10.9 rad, it remained within normal range. The elevation in serum FSH levels in one of the severely exposed subjects was noted as late as 413 days after the exposure, while the hormone levels in all other cases declined toward normal level.
