Default Bad food - bad sperm?

After centuries of women being blamed for how the children turn out, (Henry the Eighth got into beheading his wives for having the nerve to keep having daughters, when it was himself who was contributing the X or Y,) it is always refreshing to find out someone is studying the male half of the equation.

Higher risks for autism among those conceived in winter months suggest the presence of environmental causes of autism that vary by season.

Month of Conception and Risk of Autism

My attention was drawn to it via a commenter on

I was thinking about the last time we were eating a lot of really bad food, full of PUFA toxic oils and sugar, and it was Thanksgiving through Christmas/New Year. Then I thought about the 2.5-3 months it takes to create sperm, and calculated out that Feb and March must be the worst months to conceive a child, epigenetically. Low and behold, there is a study that shows that conception during those months are associated with a 6% increase in rates of autism. I know, correlation not causation, but it sure fits your theories about nutrition and health pretty well!!!!

The study itself posits possible flu virus exposure, or pesticides; they did not study any possible causation.

However, has anyone looked at diet and its effect on sperm quality? I looked around and this one seems pertinent:

Impact of obesity on male fertility, sperm function and molecular composition

Male obesity in reproductive-age men has nearly tripled in the past 30 y and coincides with an increase in male infertility worldwide. There is now emerging evidence that male obesity impacts negatively on male reproductive potential not only reducing sperm quality, but in particular altering the physical and molecular structure of germ cells in the testes and ultimately mature sperm. Recent data has shown that male obesity also impairs offspring metabolic and reproductive health suggesting that paternal health cues are transmitted to the next generation with the mediator mostly likely occurring via the sperm.

Metabolic problems create more problems.
