Gynecomastia is observed only rarely in men with classic Kallmann syndrome or idiopathic hypogonadotropic hypogonadism at the time of diagnosis, but it may occur as an adverse effect of androgen replacement therapy in these patients. 23 people with Kallmann Syndrome have taken the SF36 survey. Notably, patients with Kallmann syndrome or idiopathic hypogonadotropic hypogonadism do not experience hot flashes. In contrast to patients with Kallmann syndrome, as well as the vast majority of idiopathic hypogonadotropic hypogonadism cases, reported patients with leptin receptor mutations have central hypothyroidism as well as decreased growth hormone (GH) secretion, presumably on the basis of hypothalamic dysfunction. We acknowledge the input of RCH consumers and carers. [Full Text]. Kallmann Syndrome is occasionally associated with congenital heart diseases (atrial and ventricular septal defects, transposition of the great arteries, Ebstein anomaly, aortic arch anomalies, but also atrioventricular block, bundle branch blocks, and even Wolff-Parkinson-White Syndrome). The smell of food is part of how we taste, so not being able to smell properly means some children may find
