Nah. It's been shown that older parents run significantly higher risk for all kinds of genetic and birth defects.

Male sperm begins to degrade sometimes around 30 iirc.

People having kids around 40 years old are significantly more likely to have offspring with a ton of issues. People are having kids much later, now.

This isnt my theory. It's been discussed at length and a google will give tons of info.

  Advancing paternal age was not associated with an increase in risk for either Down syndrome or chromosomal disorders other than Down syndrome.

  Multiple neonatal and pediatric disorders have been linked to older paternal ages.  

  The risk of paternal age has been difficult to estimate and interpret because children often have parents whose ages are similar and likely to be confounded.
