為什麼毒澱粉(順丁烯二酸)(馬來酸)

會造成不孕症?


雞排


     昨天有一個聳動的新聞說:「如果一個人一年吃20片炸雞排,10年後會不孕症、洗腎、致癌!!」毒澱粉和不孕症有什麼關聯性?1985年國外有一份研究發現,直接把順丁烯二酸(也叫做馬來酸)滴到精蟲,精蟲會不動,減少穿透力,只要百分之0.01的馬來酸(0.01%)精子就減少穿透力,如果馬來酸提升到百分之0.1(0.1%)精子穿透力完全沒了,因此有人突發奇想,想到用馬來酸,放在女人子宮頸黏液,達到避孕(絕育?)電子顯微鏡研究也發現,馬來酸可以讓精子受精最重要的頂體反應不發生,所以結論是:馬來酸(順丁烯二酸)會減少精子穿透力,如果濃度更高,會減少頂體反應,甚至可以當作避孕藥,哇咧!!






















 

台灣雞排酥炸粉檢出含毒澱粉 年吃20片可致不孕


 
 
毒澱粉事件持續延燒,彰化員林一家老牌粉行,被查出向協奇引進澱粉,再自行調製成含有超量順丁烯二酸的「獨家配方」酥炸粉,並供貨給下游的雞排攤、小吃攤和鹹酥雞店等,被查扣的毒澱粉高達17公噸。醫師表示,長期食用這些含有黑心毒澱粉的雞排炸物,可能導致不孕、腎病變,甚至誘發癌症。

Effects of malonic, maleic, citric and caffeic acids on the motility of human sperm and penetration of cervical mucus.

Abstract

 
 

The spermicidal effect of four organic acids (malonic, maleic, citric and caffeic acids) was evaluated by adding the acids to sperm, and by observing sperm survival and penetration following addition of these acids to human cervical mucus. Direct addition of 0.1% malonic, maleic and citric acid rendered the sperm immotile by a reduction of pH. In capillaries filled with cervical mucus, the incorporation of 0.01% maleic, malonic and citric acids was sufficient to reduce sperm penetration, and at 0.1%, penetration was completely abolished. Thus, malonic, and maleic and citric acids show promise as cervical or vaginal contraceptives. Caffeic acid was found to be unsuitable owing to its insolubility in aqueous media. Electron microscopy indicated that human sperm do not undergo the acrosome reaction while penetrating cervical mucus in vitro.
