This Consensus Statement differs from existing guidelines for the treatment of hypogonadism as it focuses exclusively on CHH. Lastly, the fourth case-based scenario is centered on a 30-year-old male with symptomatic hypogonadism due to chronic anabolic steroid abuse. Data from the past few years suggest that GnRH neurons originate from both the neural crest and ectodermal progenitors, and migrate in close association with growing axons of olfactory and/or terminal nerves.15,16 Once in the hypothalamus, GnRH neurons detach from their axonal guides, disperse further into the brain parenchyma and stop migrating. 106, 354361 (1987). Hum. More startlingly, an estimated 6.5 million men in the United States will have hypogonadism by 2025[3]. J. Endocrinol. 20, 26882697 (2005).

Although definite evidence is lacking about the impact of testosterone therapy on metabolic endpoints, an international group of authors presents here an innovative approach based on supportive data regarding surrogate endpoints or early-term results. Dode, C. et al. Serum levels of anti-Mullerian hormone as a marker of ovarian function in 926 healthy females from birth to adulthood and in 172 Turner syndrome patients. In the absence of a gonadotropin response, this test can help to confirm severe GnRH deficiency, yet clinical signs are often already evident (that is, prepubertal testes or absence of breast development). The study established that low dose hCG treatment dose-dependently increases ITT concentrations in normal men brought about with gonadotropin deficiency. J.

In the third case-based scenario, a 42-year-old male patient with symptomatic hypogonadism has a desire to father children at an unspecified future time. Although the genetic basis for idiopathic hypogonadotropic hypogonadism is largely unknown, mutations in several genes involved in the hypothalamo-pituitary-gonadal axis development and function have recently been implicated in the pathogenesis of this condition. Cessation of exogenous testosterone should be recommended for men desiring to maintain their fertility. Appalachian State Pharmacy, Evain-Brion, D., Gendrel, D., Bozzola, M., Chaussain, J.

Interestingly, even short-term hypogonadism (such as that resulting from discontinuation of sex steroids for 2 weeks) induces increased fasting insulin concentrations in young men with CHH,246 which suggests that adherence to treatment is also important for promoting metabolic health. 67, 11401145 (1988).

Patients typically require lifelong treatment, yet 1020% of patients exhibit a spontaneous recovery of reproductive function. Enclomiphene had a much greater effect (8-fold increase to 1144 ng/dL) than clomiphene citrate (5-fold increase to 559 ng/dL). J. Med. The presence of anosmia and/or olfactory bulb hypoplasia and/or aplasia (visualized by MRI) points to Kallmann syndrome, yet measurement of levels of serum gonadotropins, sex steroids, AMH and inhibin B are not always fully informative in confirming the diagnosis.

Gong, C., Liu, Y., Qin, M., Wu, D. & Wang, X. Pulsatile GnRH is superior to hCG in therapeutic efficacy in adolescent boys with hypogonadotropic hypogonadodism.

GNRHR-related central hypogonadism with spontaneous recovery - case Hum. By contrast, the GnRH stimulation test rarely enables differentiation of CDGP from partial forms of CHHthe most challenging differential diagnosis. A low or low/normal LH level points to a secondary (central) hypothalamic-pituitary defect, (hypogonadotropic hypogonadism), while an elevated LH level indicates a primary testicular defect (hypergonadotropic hypogonadism). Cryptorchidism (particularly bilateral) can have far reaching negative effects on future fertility potential.164,165 As such, current recommendations advocate surgical correction at 612 months.166,167,168 Micropenis should be treated early using short-term, low-dose testosterone (dihydrotestosterone or testosterone esters) to induce penile growth (Table 4).86,169 Importantly, as the duration of treatment is brief, no major concerns regarding virilization or the development of secondary sexual characteristics exist; however, erections might be observed.
