Males could help in offspring’s mental development, says study
Posted: 07/02/2015 05:02 PM IST
Previous study on male pheromones have revealed that exposure to male pheromones can boost a woman's mood and stimulate the release of a hormone that regulates the menstrual cycle. From the latest study it was found that they could also help in developing the offspring’s brain before pregnancy.
The scientists measured greater mammary gland development in mice that are exposed to male pheromones a week after exposure, which may have led to greater volumes or improved quality of milk production. These mother mice also showed lengthier nursing periods compared to mice not exposed to the male pheromone.
To measure the intelligence of the offspring, the researchers placed mice in a water maze with a hidden platform. The mice born of mothers exposed to male pheromones learned the location of the hidden platform much faster, suggesting quicker learning and stronger spatial memory compared to the control group.
The study was published in the journal Proceedings of the Royal Society of London B: Biological Sciences.
