HEDS is just as prevalent in males as it is in females. It is not x linked, and sex has no bearing on transmission. It is inherited through a dominant gene pattern, which gives a 50% transmission chance regardless of sex. It tends to affect females with more issues simply because males tend to have more muscle mass which overcomes the joint instability better. Also, males are usually believed about their pain more and tend to get better investigation of pain. Interestingly, males with HEDS tend to be more affected by pain before puberty, and then females after puberty. The hormones that women experience during their menses and pregnancy and childbirth in particular have a lot of effects on the laxity of tissue.
The reason why you hear about it more in females is because munchies have coopted it and munchies are overwhelmingly female.
This is only for the unknown phenotype, of Hypermobile EDS. Other types of EDS may not have dominant gene transmission patterns. But as of now, Hypermobile EDS is the only one without the known gene. Within five years there will be a known gene though, as we are screening and researching the gene heavily due to a recent grant.
