It is rather premature to draw any conclusions about a link between
testicular cancer and PVC/phthalates
(This Week, 24 January, p 13).
Nearly all in-vivo tests of phthalates, even administered over two
generations, show no hormonal influence whatsoever, neither on uterus weight for
female rats, nor on sperm count or motility for males. In no case were more
testicular cancers found, even if extreme amounts of phthalates, comparable to
500 grams per day for an adult, were given. So it is very unlikely that
phthalates are the culprit.
