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.

I take the FSH type shot once every two weeks and I achieved a low level of sperm production after 10 months. Alternatively, the sense of smell can be evaluated by using serial dilutions of multiple odorants such as dimethyl sulfide, menthone, acetic acid, exaltolide, amyl acetate, cineole, and pm-carbinol (Olfacto Laboratories, El Cerrito, Calif), according to the protocol of Rosen and Rogol. 5-alpha-reductase deficiency.
