At BJ Care Services, we understand that autism spectrum disorder (ASD) affects individuals in unique ways. With regard to autism and gender, one widely recognised pattern in autism research is that males are diagnosed with autism more often than females. But is autism truly more common in males, or are there other factors at play?

Studies suggest that the ratio of autism diagnoses is around 3:1 or 4:1, meaning for every three or four males diagnosed, only one female receives the same diagnosis. This has led many to question whether autism is genuinely more prevalent in males or if females are simply being overlooked.

Diagnostic Bias & Outdated Criteria
Historically, researchers and clinicians developed autism diagnostic tools based on male characteristics. Early studies primarily included male participants, which shaped today’s diagnostic approach. As a result, professionals often overlook or misinterpret the more subtle signs of autism in females.

Traditional diagnostic criteria emphasise traits such as repetitive behaviors, rigid routines, and social difficulties. Although both genders exhibit these traits, females often express them differently or internalise them, making recognition more challenging.

Differences in How Autism Presents in Females
Autism does not always look the same in males and females. While males may show more outward signs—such as hyperfixation on specific topics, difficulty with eye contact, or repetitive movements—females tend to exhibit distinct patterns, including:

As a result, many females remain undiagnosed or receive a misdiagnosis of anxiety, depression, or ADHD instead of autism.

The Role of Masking & Camouflaging
One of the biggest reasons females are underdiagnosed is masking, also called camouflaging. This occurs when autistic individuals consciously or unconsciously suppress their autistic traits to conform to societal expectations.

Notably, females are more likely to learn social norms by observing others and imitating behaviors. For example, they may:

While masking helps autistic individuals navigate social situations, it often leads to mental exhaustion, anxiety, and even burnout. Unfortunately, many females who mask their autism struggle in silence for years before receiving a diagnosis—if they ever do.

Biological & Genetic Factors
In addition to social and diagnostic challenges, biological factors may also play a role in the lower diagnosis rates of autism in females. One prominent theory, known as the “female protective effect,” suggests that females may have a higher genetic threshold for autism. In other words, they may require more genetic mutations to exhibit the same level of autistic traits as males. However, this is still an evolving area of research, and further studies are needed to gain a deeper understanding of these biological influences.

For many autistic females, a diagnosis comes later in life—if at all. Without early identification, they may miss out on crucial support services, therapy, and accommodations that could help them thrive. Additionally, undiagnosed autism can lead to increased mental health struggles, such as anxiety, depression, and social isolation.

It’s essential to raise awareness of how autism presents differently across genders so that all individuals—regardless of gender—receive the understanding and support they deserve.

At BJ Care Services, we provide individualised support for people with autism, helping them build independence, social skills, and confidence. Whether through behaviour support, community inclusion, or daily living assistance, we ensure that every person receives the right care tailored to their needs.
