Yes. A woman's risk of having a child with autism increases with age. Women in their 30s and 40s are at a higher risk than younger women, and if the father's half-brother inherited autism from the parent that gave birth to the father then the likelihood of him passing it on is slightly increased as any family history of autism will make it more likely to appear in future generations. Though most cases of autism are relatively mild, the severity of the case cannot be predicted by past cases in the family. For instance, the father's half brother could be severely autistic, but he may still father an unaffected child, or one with a very mild case. I would contact a genetic counselor for further review.

According to the experts, the risk of having a baby with Down syndrome increases with a woman’s maternal age. At age 25, there is a 1 in 1,250 risk, compared to being pregnant at age 35, when there is a 1 in 400 risk. That logic might be an indicator that the 20s is indeed the right time to become pregnant.
