The evidence does not support attributing this quote to Robert F. Kennedy Jr. Multiple independent fact-checks found no record of him saying infertility is genetic or that people whose parents did not have children are unlikely to have children. The wording appears to be an older joke that was later misattributed to him, likely because of separate comments he made about sperm counts and fertility.

RFK Jr. did back Trump's executive order boosting glyphosate production, representing a shift from his prior anti-pesticide activism. However, he never publicly stated that glyphosate is "safe." In the same social media post endorsing the order, he called pesticides "toxic by design." He later called glyphosate "poison" on Joe Rogan and told MAHA supporters he disagreed with Trump's decision. The claim's core assertion — that he told supporters the herbicide is safe — is directly contradicted by his own recorded statements.
