The Guardian published a feature by Zoe Williams examining misinformation about male fertility, testosterone and reproductive fitness, which the outlet says is rife in the manosphere. According to The Guardian, such misinformation can lead to a lot of heartache. The piece, headlined “The truth about testicles: are we facing spermageddon?”, was published on November 1, 2026.

The article profiles Michael Carroll, whom The Guardian presents as a man who wants to change that situation. The outlet reported that Carroll is the author of a book titled Your Nuts, whose cover is illustrated with two walnuts in a string bag. Carroll is quoted as saying, “I think you can tell it’s for a lay audience,” while holding up the book.

The Guardian also reported that the book has arrived in tandem with worldwide concerns, although the summary of the article breaks off at that point. The summary does not say who holds those concerns, what they are, or how widely they are shared, so this report does not characterize them. The only reference to them in the material reviewed is the headline’s question about whether readers are facing spermageddon.

This report draws only on the headline, byline and partial summary of the article, not the full text. The material does not include a dateline location, statistics, study findings or specific claims of misinformation, and none are reported here. The sources reviewed for this story are a single article, so no other outlet’s reporting is compared. Readers seeking the complete reporting should consult the original article under Williams’s byline.
