Kallmann syndrome and the related condition congenital hypogonadotropic hypogonadism (CHH) are a rare causes of delayed or absent puberty in both males and females. 

I hope to bring together information on Kallmann syndrome (KS) and CHH so it is easily accessible to both patients and clinicians.

It is a work in progress and over time I hope to develop the website into a useful information source for both patients and clinicians. 

Any comments or queries about the content or suggestions would be welcome.
