paternal factors on prenatal development - ANS--Exposure to certain toxins can lead to abnormal sperm,
leading to birth defects or low birth weight
-Later paternal age associated with some birth defects and with autism
-Offspring of men > 40 years were 5.75 times more likely to have autism compared with offspring of
men < 30 years
, -Maternal age did not relate to autism
