Beer has the effect of strengthening the spleen and appetizing, and many people regard it as a daily soft drink, even known as "liquid bread.". Especially in summer, beer becomes a favorite accompaniment drink. British scientists have recently warned that beer directly affects male fertility.
According to reports, Lynn Fraser, a fertility expert at King's College London, has studied three chemicals that affect fertility - genistein in soybeans and other legumes, 8-prenylnaringenin in hops, and benzononyl in detergents, paints, herbicides, and insecticides. Scientists have discovered that these substances can mimic the work of estrogen
Experts explain that when sperm encounters an egg, they release an enzyme that breaks through the outer membrane of the egg, and estrogen can stimulate sperm activity. If immature sperm is stimulated prematurely and releases the enzyme before it encounters the egg, but when it is truly needed, it cannot break through the outer membrane of the egg, then fertility will inevitably be affected.
