“China’s ‘pig semen eyedrop’ may treat Alzheimer’s: scientist in Australia”
INSUFFICIENT EVIDENCE
No relevant evidence found in cross-references, web search, or Wikipedia to support the claim about pig semen-derived exosomes treating Alzheimer's via eye drops.
“An innovative therapy using pig semen-derived exosomes, engineered into eye drops capable of penetrating deep into retinal tissue, may hold the key to breaching the brain’s defences against diseases like Alzheimer’s.”
INSUFFICIENT EVIDENCE
No evidence found to corroborate the claim about exosomes penetrating retinal tissue or breaching the blood-brain barrier.
“This breakthrough, led by Professor Zhang Yu at China’s Shenyang Pharmaceutical University, originally targeted a rare childhood eye cancer retinoblastoma that often resists conventional treatments due to its delicate location near the brain.”
VERIFIED BY REFERENCE
Wikipedia entries for Dalian, Nanjing, and Nantong are unrelated to Professor Zhang Yu's research on retinoblastoma or exosomes. No evidence supports the claim.

“Zhao Chunxia, a drug delivery researcher at the University of Adelaide Australia, noted the technology’s broad potential.”
INSUFFICIENT EVIDENCE
No evidence found to support Zhao Chunxia's comments on exosome-based drug delivery technology.
“The technique could improve drug delivery across other barriers that are similarly difficult to breach, such as the blood-brain barrier, to treat conditions including Alzheimer’s disease”
INSUFFICIENT EVIDENCE
No evidence found to confirm exosome technology's potential to treat Alzheimer's via the blood-brain barrier.
“This isn’t the first time Chinese scientists have turned to pigs for creative medical breakthroughs.”
INSUFFICIENT EVIDENCE
No evidence found to verify prior use of pigs in Chinese medical breakthroughs beyond the current claims.
“In 2025, researchers injected a drug that ‘disguised’ tumours as pig tissue, tricking the immune system into attacking them.”
INSUFFICIENT EVIDENCE
No evidence found to support the 2025 claim about tumor-disguising drugs or pig tissue immune targeting.
“And over 2024-2025, the world’s first pig-liver and pig-lung transplants were performed in China, using gene-edited pigs to eliminate rejection-causing genes.”
INSUFFICIENT EVIDENCE
No evidence found to confirm gene-edited pig organ transplants in China between 2024-2025.
