Paywalled, cant read :(
Lemme guess… microplastics, higher temps (balls are outside the body to maintain a cooler temperature).
No, endocrine disrupting chemicals - which include pesticides, bisphenols, and phthalates.
I stand corrected, my guess was wrong!
It’s very frustrating, feels like as end-users & citizens we have no control over our exposure to these chemicals.
We don’t. And bisphenols are in a TON of plastic (including the plastic food and drink comes in and is kept in) which lower testosterone and raise estrogen levels.

“For more than two decades she has devoted her life to studying the effects of “endocrine disrupting” chemicals(opens a new window) (EDCs), which can interfere with the body’s natural hormones. These include pesticides, bisphenols(opens a new window), which harden plastic so it can be used in food storage containers and baby bottles, and phthalates(opens a new window), which soften plastic for use in packaging and products such as garden hoses. In recent years, traces of EDCs have been found in breast milk, placental tissue, urine, blood and seminal fluid.”
