This article specifically talks about sperm deterioration with age in men. As far as autism, there have been several studies. Check below article and the studies referenced.
Are older fathers more likely to have children with autism? A series of epidemiological studies is giving credence to the idea, suggesting that, with age, sperm may accumulate damage that increases…

No doubt on the sperm part. That said, nothing against you at all here, but I'm not buying the studies referenced by the author with relation to autism upon reading them. Reichenberg admits he didn't conduct deep correlation analysis because of sample size limitations and Croen's methodology had gaping holes in it. Even despite that fact, the latter concludes that parental age "is still a relatively small contributor" to autism. In fairness, the research in this area appears to be all over the board, from people claiming that data "suggests" the two factors are related, to those who take a more balanced statistical approach who say
there is no independent relationship between paternal age and autism.
Even assuming that the evidence which suggests there is a higher rate of autism prevalence in older fathers is correct, that evidence which does exist is laughable in terms of drawing any meaningful conclusions from it. While Spectrum News puts out the gaudy headline that "
paternal age ups the rate of autism," they reference data from Jonsson,
which shows a 1.50% chance of males in their 20's having an autistic baby vs. 1.58% for those in their 40's. That is not a statistically significant difference. (And keep in mind this statistic is for men in their 40's paired with a woman also in her 40's). Such paltry results aren't even worthy of funding for further research tbh. They certainly aren't anything someone in their 40's should consider problematic for even one second when banging a girl.
Though 40 is awhile away, if some hot girl temporarily loses her vision and wants bang me at that age, it won't be on mine, that's for sure.
I find the lack of appreciation for epigenetics alarming in the studies these autism groups are doing. It seems like they're just trying to pin matters, the hypothetical causes of which aren't even well developed in socially-acceptable circles, onto the most lazy, lowest common denominator factors imaginable. And not surprisingly, it seems some are attempting to pin causation on men (i.e. male age) whilst ignoring other potential factors in the human ecosystem (chemical, environmental, etc.).
I could go on, but since this isn't a science forum, I'll leave it there.
