Kids Health – XYY syndrome is a genetic condition found in males only.

XYY Syndrome is a genetic condition caused by a random split in the cells at conception, creating an extra copy of the Y Chromosome (XYY). XYY boys are often taller than average and may suffer from hypotonia (weak muscle tone). They may also have delayed speech development and some learning difficulties, particularly those related to executive function. Many boys display poor impulse control, particularly in the younger and teenage years, and find it hard to both emotionally regulate and process sensory inputs. These struggles in their earlier years have a significant impact on their social development, making it difficult for them to form meaningful and lasting friendships or relationships. This leads to further isolation and deterioration in self-worth.

There is a requirement for the recognition of XYY Syndrome as its own stand-alone diagnosis, requiring specific XYY-related specialist support. This recognition will allow the early intervention of supports and therapies to ensure all XYY boys and men have the opportunity to live fulfilled lives.

    I was told by specialists that the “common ” for all sufferers are
    Zero sperm count.
    Giant size ( over 6 foot 4 inches)
    and usually small hands.
    Most other difficulties are a mixed bag, which some have and some don’t.
