Why are sex linked genetic disorders more common in males in Derby

The seemingly inevitable demise of the KS testes has not been elucidated, and research within this area will be exciting in the years to come. We need to develop a more thorough understanding of the fundamental genetics and genomics of the syndrome to fully address the endocrine, neurocognitive, and cardiovascular disturbances.

Conversely, when comparing KS males with the male background population, delayed ejaculation was experienced significantly more often in men with KS No universal agreement exists in the scientific community on the exact definition of KS, but in addition to possessing one or more extra X chromosomes, KS males typically exhibit phenotypical traits that include hypergonadotropic hypogonadism, testosterone deficiency, and infertility 2.
