I think it's important to share household products, the environment, what is it doing to sperm, or is it okay to just ignore that?

So, I think the point about the environment and fertility, it is largely about multiple exposures throughout life, where life is actually beginning at the time of conception or even before.

So it's about the lifestyle of the parents, which may be affecting both, uh, the quality of their gametes and their ability to conceive.

But then it is about the environment to which the fetus is exposed, particularly a male fetus at a time in the first, uh, few weeks, uh, of this little fetus's life is crucially dependent upon the production of testosterone.

And if in the environment there are endocrine-disrupting chemicals, then this is going to adversely affect the development of that fetus's gonads.

And then again, so there's a, a first hit, if you like, that might have affected the sperm that went to make the fetus.

Then the fetus is exposed via its, uh, via, via the maternal environment, and then the infant may be exposed to the external environment after birth, when again there should be another testosterone surge.

they understand what's, um, what's happening and why?
