OBSTETRIC-GYNECOLOGICAL STUDY ON WOMEN RECEIVING IRRADIATION IN SMALL DOSES ON THE LOWER ABDOMEN
The effects of diagnostic x-ray exposure on reproductive function and on the offspring were investigated in 105 women in comparison with 131 control women who had not received abdominal radiation. The estimated radiation dose applied to the ovaries in hysterosalpingography was 200 to 550 mr (average 400 mr) and in fetal roentgenography about 560 mr. The irradiated women reported a shorter duration and less amount of menstruation after as compared with before irradiation but menstruation parameters were similar in the irradiated and control groups. The average age at menopause was the same in the 2 groups. Pregnancy rate increased markedly after salpingography; it rose to 46% in women who had been infertile before this procedure. The frequency of spontaneous abortion was higher before irradiation (13.2%) than after (8.2%), whereas the frequency of stillbirths was the same in both instances. Although the sample was too small for definite conclusions, irradiation appeared to have no influence on the offspring with respect to sex ratio, weight at birth, and incidence of postnatal death. No malformed infants were born to the irradiated mothers. It was concluded that diagnostic x radiation at the doses employed have no significant effect on gonadal function or on the first generation offspring. (H.H.D.)
