I have to wonder about the effects of wearing synthetic clothing as well. I knew a guy who was a geriatric pharmacologist and he was heavily into cycling. He routinely wore skin tight cycling shorts. He and his wife had difficulty with conception. I do not have data to support that synthetic cycle shorts were a contributing factor but I wonder all the same. I got rid of synthetic clothing in my own wardrobe as an added precaution.
The Q&A format works well for Swan's work. It forces specificity on a topic that usually stays at alarming-headline level and never gets concrete.
The part that sticks with me is the personal care product exposure pathway. It's not just food packaging and plastic water bottles. Phthalates go in daily through skin contact too. Most people don't have a mental model for that route at all.
Has the conversation here landed mostly on the food and water angle, or are readers engaging with the personal care piece too?
There is another environmental toxin (not mentioned above) which is impacting sperm, aluminum. Aluminum can be removed from the body by drinking silica rich mineral water. Here is an excerpt from one of Dennis N Crouse's book, "Silica Water the secret to ....... ". Dennis was interviewed in this substack. "Spermatogenesis is the process by which sperm are produced by the testis. Aluminum has been found to inhibit spermatogenesis in rats and voles341-343. In the case of rats the aluminum was administered orally at human dietary levels for just 60 days341. In 2014 aluminum was found in human semen at a mean concentration of 339mcg per liter with some patients having over 500mcg per liter. Patients with high sperm count had low levels of aluminum in their semen while patients with low sperm count were found to have higher levels of aluminum in their semen344. This was the first solid evidence that aluminum not only inhibits spermatogenesis in some mammals but also inhibits spermatogenesis in humans and is likely a causal factor in the decline of worldwide male fertility.
Sperm motility (i.e. mobility) is required for fertilization. In 2016 aluminum was found to inhibit human sperm motility345. There is evidence that aluminum lowers sperm motility by facilitating higher levels of reactive oxygen species (a.k.a. ROS) in the sperm345." Here are the references. 341.

Vitamin D has been shown to improve fertility in over 50 studies
https://vitamindwiki.com/tiki-index.php?page_id=3440
- - - - - - Some examples - - - - - -
Male fertility 4 X higher if high Vitamin D – Nov 2015
Unknown cause (idopathic) for male Infertility appears to be low vitamin D (9 X) – Sept 2022
Women have conception problems when vitamin D levels are less than 24 ng – meta-analysis May 2024
3X more pregnancies when Vitamin D levels are high (assisted reproduction, women only) – Oct 2021
Vitamin D is needed for human fertility – goal is 50 ng – Sept 2018
In-vitro Fertilization costs at least 10,000 dollars, Vitamin D costs 5 dollars
