hahax32406 is right. These same claims have been made since the early seventies (as far as I can recall). If they were honest about their claims they'd have published their data in peer-reviewed journals long ago.

While there is no scientifically proven "detox" method to instantly remove accumulated microplastics from the human body, the body does naturally excrete some ingested plastic through waste. While some plastics can remain in tissues, reducing exposure is the primary way to manage and decrease the body's plastic burden.

Unfortunately, humans cannot detox from plastic. Look it up. So if previous exposure to plastic is the cause for these couples not having babies, then there is nothing they can do to mitigate that. If this doc ends with any of of the couples having children, then it likely wasn't plastic that was previously preventing them.
