There is no direct link between autism and fertility, however, some studies suggest that there may be a higher rate of infertility among people with certain conditions associated with the autistic spectrum. Additionally, treatments for autism may affect fertility rates in both men and women on the spectrum.
The first study to suggest an association with ASD reported a higher prevalence of infertility in mothers of children with ASD; however, the study size was small, and analyses were not adjusted for possible confounders [16]. Two larger, more recent studies reported no association between infertility and ASD [17,18].
Autism does not affect sexual development, and autistic people can have a fulfilling sex life. However, individuals may have varying approaches to romantic relationships due to differences in sensitivity and communication.
Some evidence suggests that autistic individuals may have a higher likelihood of experiencing: health conditions which can affect pregnancy such as heavy menstrual periods and polycystic ovary syndrome (PCOS) mental health conditions such as post-natal depression or anxiety.
Maternal autism is associated with preterm birth, likely due to an increased frequency of medically indicated preterm births, but also with other adverse pregnancy outcomes, suggesting a need for extra surveillance during prenatal care.
Since autism is less prevalent in females, autism was always thought to be passed down from the mother. However, research suggests that autism genes are usually inherited from the father.
Key Takeaways. A study notes that waiting at least two-and-a-half years between births may decrease the possibility of a second child receiving an autism diagnosis. There are numerous other factors that can contribute to a child being identified on the autism spectrum.
If someone in your family has autism spectrum disorder (ASD), you may be more likely to have a child with ASD. ASD can look very different from person to person, so taking a careful family health history can be important for early diagnosis.
There are many different factors that have been identified that may make a child more likely to have ASD, including environmental, biologic, and genetic factors.
“Firstborn offspring of two older parents,” Durkin's study noted, “were three times more likely to develop autism than were third- or later-born offspring of mothers aged twenty to thirty-four and fathers aged under forty years.”
Autism spectrum disorder (ASD) is a heterogeneous, behaviorally defined, neurodevelopmental disorder that has been modeled as a brain-based disease. The behavioral and cognitive features of ASD are associated with pervasive atypicalities in the central nervous system (CNS).
Background. A substantial amount of research shows a higher rate of autistic type of problems in males compared to females. The 4:1 male to female ratio is one of the most consistent findings in autism spectrum disorder (ASD).
Autism was always thought to have a maternal inheritance component, however, research suggests that the rarer variants associated with the disorder are usually inherited from the father.
Among all families affected by autism, up to 19 percent have more than one child with the disorder, according to one large study. Multiplex families, especially those who have twins, have led to many of the breakthroughs in our understanding of autism.
Advances in diagnostic capabilities and greater understanding and awareness of autism spectrum disorder seem to be largely driving the increase, the Rutgers researchers said. But there's probably more to the story: Genetic factors, and perhaps some environmental ones, too, might also be contributing to the trend.
1 in 100 children are diagnosed with autism spectrum disorder as of 2021. Autism prevalence has increased 178% since 2000. The country with the highest rate of diagnosed autism in the world is Qatar, and the country with the lowest rate is France.
High levels of stress during pregnancy may also be connected to autism in children. This connection appears to have the most impact when the parent experiences stress between weeks 25 and 28 of pregnancy.
Some children with autism smile to show they're happy but don't share their enjoyment. Others show little facial expression or have flat affect and rarely smile so you may not know when they're happy.
Smoking, alcohol, and drug consumption during pregnancy have been shown to increase the risk of women having an autistic child.

They note that sibling relationships can be especially good for autistic children, and you can help build these relationships. All these parents say it's important to give all children love, time and attention, and they suggest ways you can do this.
The chances of anyone in the general population having an autistic child are about 1 in 1000 or 0.1%. So, while the risk is real, the chances of you and your husband having an autistic child are still very low.
So if there's no genetic history in the family, where does a child's autism come from? A key fact has come to light within the last couple of years: many autism-causing genetic mutations are “spontaneous.” They occur in the affected child, but in neither parent.
