Putrescine water doubles fertility in aging females
juin 24, 2015
New research led by Dr. Johné Liu shows that drinking water supplemented with putrescine can turn back the biological clock in aging female mice and help them have more babies. Putrescine is a naturally occurring small compound produced in many tissues throughout life, particularly during egg cell maturation (when egg cells divide to get ready for ovulation and fertilization). Dr. Liu and his team have previously shown that egg cells from aging mice produce less putrescine than those from younger mice, and supplementing with putrescine water can reduce the number of defective eggs. Their new study, published in Human Reproduction, shows that putrescine supplementation can also increase live births in older mice – in fact doubling the number of offspring, with no toxicity. Dr. Liu is continuing his research in other experimental models, with hopes of advancing to human clinical trials in the future.
