Gossip: Soy milk is bad for man,because soy milk contains estrogen.It will
made man develop breasts, no beard, sissy and all other feminine characteristics.Some
viewpoint thinks that soy milk may made decrease in the number of sperm,I.e. soy
milk kills sperm.
Trueth:In fact,there is no reason that soy milk makes men feminine, it
hasn’t been demonstrated that soy milk kills sperm.
Soy Milk Makes Man Feminization?
Because the biological activity of “phytoestrogen” is only milli of drugs
estrogen,so it won’t reverse the hormonal balance to affect male genital or the
boy’s normal development,so long as you didn’t intake too much.
Soy Milk kills the sperm?
This statement originate from animal
experiment.Then a good deal of scientists are engaged in human research.
In 2008,an article published in Human
Reproduction made a research by means of questionnaire survey,and concluded that
the quantity of soy products intaken is negative correlation with sperm
concentration.But the scientists himself said :”It is unable to establish
causality of intake of soy and sperm concentration with this experiment”.On the
other hand, “phytoestrogens is good for protect the wholeness of sperm DNA and avoid
damage” ,a scientist found.But the mechanism of prevents the damage is
unclear,it needs further research.
In 2009,a research published in Fertility
and Sterility also put forwards an conclusions which is contrary to “kill sperm
”. By compared experiments,scientists found that the sperm count and vitality of the people who eat meat or any other fat
food long-term is decreased ;however people who eat vegetables,fruits and beans
enjoys a high quanty and quality sperm.Maybe it is because these food contains
a lot of antioxidant substance.Most research found that a diet high in
antioxidants often means better sperms.Soybean contains abundant antioxidant,maybe
this is the reason it is benefit to sperms. In the same year,another meta-analysis
published in the same journal found that even though high dose of soybean
isoflavone won’t affect the quanty and quality of sperms.
Researcher thinks that although there are
some animal experiment and cell experiment has found that soybean and plant
hormones affects fertility function.But to human,related research is still not comprehensive,and
still needs intense research.The newest meta-analysis also holds the same
opinion :the effect of soy foods on fertility is unknow.
