Kallmann Syndrome affects males about four times as often as females. The reason for this is partly because of the way it can be inherited. In x-linked forms of Kallmann Syndrome, more men will be affected than women. This is because men only have one X-chromosome, so they only need to inherit one gene from one parent. Women have two X-chromosomes, so they would have to inherit two copies of the gene, one from mom and one from dad, which happens much less often. In addition, men tend to seek care for delayed puberty more often than females. Therefore, it may also be that more males are being diagnosed than females.
