LETHBRIDGE: New research from the Canadian Centre for Behavioural Neuroscience at the University of Lethbridge is suggesting that when it comes to trying to have kids, men may need to try and relax first.
The study, which was recently published in the journal Neuroscience, showed that the offspring of male rats who were stressed for 27-days prior to mating with a female, were developmentally delayed.
Dr. Robbin Gibb was a major part of the project, and noted that there was also a greater impact on male offspring. She stated, "It appears that preconception experiences alter the expression of the DNA contained in sperm, particularly those containing the Y chromosome."
Gibb did note a few important things for men to consider when looking to grow their family, "About every 75 days you get new sperm, so if you've had something very traumatic happen you might want to just wait a couple of months before you decide to conceive. Also you can do more of the relaxation kind of things that we know can reduce stress- exercise, meditation, that kind of thing."
On a more positive note, Gibb pointed out that this study meshes well with a previous one, "It was exciting for us because a few years ago we did a study where we enriched fathers, we put them in an environment where they had lots of toys and other animals to interact with, and we had positive effects on the genome in that case. So we can see it works in both ways, and I think that's good news for dads."
