The effects of estrogen-like products in milk on prostate and testes / 中华男科学杂志

ABSTRACT

<p><b>OBJECTIVES</b>To study the effects of estrogen-like products in milk on the male reproductive system.</p><p><b>METHODS</b>The incidence rates of testicular and prostatic cancers in 42 countries (regions), collected from the cancer incidence in five continent database (1988-1992), were correlated with the relative food consumption in these countries, which was provided by FAO database (1961-1990); two-generation reproduction test was taken by using Wistar rats according to FDA standard.</p><p><b>RESULTS</b>Among the food items examined, milk was most closely correlated (r = 0.711) with prostatic cancer incidence, followed by meat and coffee. As for testicular cancer, cheese was most closely correlated (r = 0.804) with the incidences in ages of 20-39, followed by animal fat and milk. No significant decreases of reproductive organ weight were found after the rats had been fed a lot of milk for long time.</p><p><b>CONCLUSIONS</b>The results suggest that further studies should be taken on the effects of estrogen-like products in milk on the male reproductive health.</p>
