The gonads in males are the testes, and the gonads in females are the ovaries.

In adult humans, it is found throughout the cerebellum and forebrain it is also found in the testes.

These are the dissected gonads of an animal that has two testes, two ovaries, another large testis, more ovaries, which is not normal ...

Now if I told the men in this village that the frogs have pour immune function and eggs developing in their testes, the connection between environmental health and public health would be clear.

It's not just my work in amphibians, but similar work has been shown in fish in Europe, holes in the testes and absence of sperm in reptiles in a group from South America and in rats, an absence of sperm in the testicular tubules as well.

And the frogs that are exposed to atrazine, the testes are full of holes and spaces, because the hormone imbalance, instead of allowing sperm to be generated, such as in the testis here, the testicular tubules end up empty and fertility goes down by as much as 50 percent.
