[The national cancer fund (Koningin Wilhelmina Fonds) and the Houtsmuller-therapy for cancer].

Dr. Houtsmuller, a retired internist, introduced an anticancer diet ten years ago. He claimed to have cured himself from metastatic melanoma by following a diet consisting of healthy nutrients, large amounts of vitamins, minerals, antioxidants and shark cartilage powder in combination with psychological support. The efficacy of the therapy was never described in a scientific article. Currently about 63% of all cancer patients in the Netherlands using a diet use the Houtsmuller diet. The national cancer fund (Koningin Wilhelmina Fonds) invited him to speak at their 50-year commemorative symposium. Shortly before he admitted that his medical history did not mention metastatic melanoma. Dr. Houtsmuller has seriously damaged the position of physicians in the Netherlands by addressing patients directly without first seeking support from his scientific medical peers. Cancer organizations such as Koningin Wilhelmina Fonds are urged to properly inform the public about the real value or lack of value of alternative treatments in general and of alternative diets in particular.

Prognosis of fertility in women with unexplained infertility and sperm agglutinins in the serum.

From 1967 to 1973 serum samples of 1709 infertile women were tested for antispermatozoal antibodies with the gelatin agglutination test. In 110 cases sperm agglutinins were demonstrated in titers ranging from 4 to 1024. The clinical data of 99 couples were evaluable, and in 65 there appeared to be unexplained infertility. Out of these 65 women, 44 became pregnant in the posttesting follow-up period of 6 to 13.5 years (median, 10 years). With increasing titers there was a significant decrease in the probability of becoming pregnant. Of the women who became pregnant, in general, those with higher titers had to wait longer for their pregnancy than those with lower titers. Moreover, with increasing titers there was a tendency toward a longer duration of infertility before the serum was tested. This latter observation supports the contention that the agglutinin titer influences the fecundability rate. The titers of those becoming pregnant and those remaining infertile, however, showed considerable overlap. Favorable results in the postcoital test were associated with a better prognosis, but this was independent of the titers.
