These environmental estrogens reach the egg before natural estrogens, but they usually present greater ovulation problems.

The British scientist Lynn Fraser has carried out an experiment to demonstrate this affirmation: on the one hand, he has mixed the mouse sperm with a female estrogen and, on the other, has mixed the rest of the sperms with soybeans, vegetables, hops, beer, herbicide and pesticides. Half an hour after the experiment, most environmental estrogens began to develop before they were usually reproduced with natural estrogens. At one hour, the three quarters of the seeds were already ripe. Fraser has come to the conclusion that environmental estrogens have more strength than natural maturation, but that reproduction costs them a lot.

The British researcher presented this week the results of his research at the European Association of Fertility and Human Embryology of Vienna, with the aim of dealing with the current problems of pregnancy of many women.
