Presentation
In this report, we offer a brief overview of the diagnosis and management of IHH and present the case of a 27 year old male with undiagnosed IHH. [omicsonline.org]
Prevalence of HH Several studies over the last few years have confirmed that HH is present in 25-40% of men with type 2 diabetes. [endocrineweb.com]
Because the suppression of GnRH exists on a spectrum, so too does the clinical presentation. [clinicaladvisor.com]

- Infertility
Case Report An infertile couple presented with 5 years of primary infertility with male partner having azoospermia. The male partner was a 32-year-old businessman, nonsmoker, and nonalcoholic. [fertilityscienceresearch.org]
This case highlights the value of obtaining a detailed history and performing a thorough physical examination as this patient’s risk of cancer, fractures, and infertility could have been dramatically reduced with an earlier diagnosis. [omicsonline.org]
HH may present as either congenital or acquired, but the majority of cases are of the former nature. [1] [2] Symptoms [ edit ] Examples of symptoms of hypogonadism include delayed, reduced, or absent puberty, low libido, and infertility. [en.wikipedia.org]
In addition, we can estimate that nearly 50.0% of couples with infertility have an underlying genetic abnormality [ 1 ]. [content.sciendo.com]
Language English Division of Urology, FCM - UNICAMP Clinical background: Twenty seven year-old male patient is referred to our infertility clinic. He has been married for 5 years with a 2 year infertility history. [fcm.unicamp.br]
- Surgical Procedure
By the age of 3, he suffered 4 surgical procedures for bilateral cryptorchidism without improvement. Around the age of 8, dwarfism was recorded without further investigations. [umbalk.org]

Respiratoric
- Hyposmia
Kallmann syndrome (KS) is a rare genetic disorder characterized by hypogonadotropic hypogonadism associated with anosmia or hyposmia. When anosmia is absent it is simply referred to as idiopathic hypogonadotropic hypogonadism (IHH). [radiopaedia.org]
Isolated or apparently isolated forms (i.e., Kallmann syndrome with anosmia or hyposmia not spontaneously expressed by the patients) of these diseases are most of the time discovered during adolescence or in adulthood in reason of lacking, incomplete [em-consulte.com]
All patients with Kallmann syndrome by definition have anosmia or severe hyposmia. [misc.medscape.com]
HH may occur with anosmia/hyposmia (Kallmann Syndrome, KS), or without it (normosmic HH, nHH). [journals.plos.org]
[…] gonadotropins LH and FSH. [2] Hypogonadism due to low levels of testosterone in men or oestrogen / progesterone in women. [2] Infertility. [1] Non-reproductive features [ edit ] Total lack of sense of smell ( anosmia ) or markedly reduced sense of smell (hyposmia [en.wikipedia.org]
Ears
- Hearing Impairment
Checking sense of smell using odorant panel or University of Pennsylvania Smell Identification Test (UPSIT) Checking for hearing impairment. Checking for missing teeth or presence of cleft lip and/or cleft palate. [en.wikipedia.org]
Zoom Finally, the presence of non-reproductive non-olfactory additional disorders, including mirror movements, palate anomalies, renal agenesis (ultrasonography), hearing impairment (audiometric testing), and tooth agenesis, should be carefully searched [em-consulte.com]
The latter are suggested to represent a mild end of CHARGE phenotypic spectrum due to overlapping features of these syndromes such as hypogonadism, anosmia, cleft lip and palate, hearing impairment, and semicircular canal hypoplasia [32], [33]. [journals.plos.org]
Musculoskeletal
- Muscular Atrophy
(more common with primary hypogonadism), muscular atrophy, osteoporotic fractures, and height loss.[ 4 ] As a comorbid condition, hypogonadism occurs with increased frequency among men with osteoporosis, osteoporotic fractures, type 2 diabetes, metabolic [bcmj.org]
Urogenital
- Cryptorchidism
Cryptorchidism is associated with an increased risk of testicular cancers. This risk nearly doubles when cryptorchidism is bilateral. Orchiopexy will reduce, but not eliminate the risk for cancer. [omicsonline.org]
As a rulethe penis remains infantile and the testes do not descend into the scrotum (cryptorchidism). No sexual development occurs at puberty. [medical-dictionary.thefreedictionary.com]
By the age of 3, he suffered 4 surgical procedures for bilateral cryptorchidism without improvement. Around the age of 8, dwarfism was recorded without further investigations. [umbalk.org]
Testes are often small or cryptorchid. Testosterone levels may be low with high gonadotropin levels. [msdmanuals.com]
- Primary Amenorrhea
Table 4 3, 6, 15 includes the differential diagnosis of primary amenorrhea. [aafp.org]
CHH is revealed in the majority of female teenagers and women by primary amenorrhea [ 1, 2, 3, 4, 5, 6 ]. [em-consulte.com]
At age of 15 she had primary amenorrhea thus she was referred for an endocrine check-up. [umbalk.org]
Males exhibit a lack of muscular development and failure of the voice to deepen, whereas females typically exhibit minimal to a complete lack of breast development coupled with primary amenorrhea. [omicsonline.org]
Affected females usually present with primary amenorrhea and do not have a completed secondary sexual development, such as having little or no breast development. 3,4 KS and other syndromes causing a congenital deficiency of gonadotropin-releasing hormone [hormones.gr]
Workup
[…] in testosterone that occurs in the afternoon.[ 4-6 ] Screening for hypogonadism in the general population is not indicated.[ 4 ] Case finding in selected circumstances is, however, acceptable, such as when testing for low testosterone is part of the workup [bcmj.org]
This is also true in patients with an elevated prostate-specific antigen (PSA) >3 ng/mL, without further urologic workup. 7 Goals of Therapy Goals of treating hypogonadal patients are focused around improvement of those symptoms, many of which can be [uspharmacist.com]
Diagnosis [ edit ] Diagnosing KS and other forms of CHH is complicated by the difficulties in distinguishing between a normal constitutional delay of puberty or a case of KS/CHH. [27] [4] [28] The diagnosis is often one of exclusion found during the workup [en.wikipedia.org]
Electroencephalography This should be conducted as a part of the workup of patients with Kallmann syndrome and seizures. A detailed discussion of electroencephalography (EEG) findings in these patients is beyond the scope of this review. [misc.medscape.com]
Serum
- Testosterone Decreased
The most frequently reported drug-related AEs were estradiol increased ( n = 3), blood testosterone increased ( n = 2), and blood testosterone decreased ( n = 2); there were no other AEs considered to be drug-related reported in more than one subject [rbej.biomedcentral.com]

Treatment
Treatment for female hypogonadism If you’re female, your treatment will involve increasing your amount of female sex hormones. Your first line of treatment will probably be estrogen therapy if you’ve had a hysterectomy. [healthline.com]
In general, treatment options most require lifelong treatment but for the rare cases of reversal [ 5 ]. [omicsonline.org]

According to the study conducted by Carone et al, a therapy cycle is described as gonadotropin treatment for a maximum of 16 days and OI by a single administration of human chorionic gonadotropin (hCG) on the day after the last gonadotropin treatments [dovepress.com]
Prognosis
Treatment and prognosis Treatment is primarily aimed at restoring normal pubertal development and in some case normal fertility. The former can be achieved by administration of exogenous sex steroids, appropriate to the gender of the patient. [radiopaedia.org]
Prognosis and outcome The reversibility of FHA by CBT has been demonstrated in a pilot study only. The long-term impact of other interventions, such as hormone replacement therapies or antidepressants remains to be established. [clinicaladvisor.com]
Ovulation induction can be achieved either with pulsatile GnRH therapy or alternatively with gonadotropin injections (hCG, FSH, hMG) given at set intervals to trigger the maturation and release of the egg for natural conception. [37] Prognosis [ edit [en.wikipedia.org]
Short metacarpals and pes cavus Ichthyosis Cleft lip or palate References Prognosis Patients with Kallmann syndrome and those with idiopathic hypogonadotropic hypogonadism can survive for lengthy periods in the absence of associated life-threatening conditions [misc.medscape.com]
Etiology
Causes [ edit ] There are a multitude of different etiologies of HH. [en.wikipedia.org]
If the patient has normal pubertal development and a uterus, the most common etiology is congenital outflow tract obstruction with a transverse vaginal septum or imperforate hymen. [aafp.org]
Our case reports suggest that maybe screening for hypogonadism in all HIV-infected men might help to understand its etiology. [edmcasereports.com]
Chapter First Online: 08 March 2017 Abstract Hypogonadotropic hypogonadism, regardless of its etiology, is one of the causes of male infertility which can benefit from medical treatment. [link.springer.com]
Epidemiology
Epidemiology First, it is thought that androgens are extensively cleared in adipose tissue in obese patients. Furthermore, aromatization of androgens rises with increased levels of adipose tissue. [uspharmacist.com]
