Hypogonadism in males study abroad – Treatment of Hypogonadism: Current and Future Therapies

Clinical presentation of HH depends on the time of onset ie, congenital vs acquired , the severity of the defect, and the presence of associated conditions. Aging males are more likely to have an acquired cause or idiopathic etiology of hypogonadism.

Both the transdermal gels and patches provide more physiologic administration of testosterone when compared to the intramuscular injections. Although administration once every weeks is more convenient, it is known to cause greater fluctuations in testosterone levels and, therefore, symptoms. Similar to a recent study, recombinant FSH pretreatment followed by GnRH is successful in inducing testicular growth and fertility in men with congenital hypogonadotropic hypogonadism with prepubertal testes [ 23 ].

They include suppression of gonadotropins by hyperprolactinemia, steroids, illness, diabetes, morbid obesity, inhibition of HPT axis by drugs, toxins, chronic disorders, eating disorders, and damage to gonadotroph cells by tumors, infections, and trauma. Lastly, we will discuss the data available on alternative therapies occasionally used for the treatment of male hypogonadism. Therefore, a diagnosis of hypogonadism by a single subnormal serum testosterone level is inappropriate. Therefore, it is important for healthcare providers to be familiar with how to conduct and interpret diagnostic tests as well as with appropriate use of TRT as established by various medical organizations, including the Endocrine Society. Academic Editor: Maria L. Diabetes Obes Metab.

Hypogonadism in KS males is part of the explanation for development of metabolic diseases in KS, although it is also plausible that genetic factors play a role [ 236 ]. All participants had to hand in their medical records for IHH and provide their contact means such as the E-mail address and telephone number, so that the investigators could check whether or not the information that the participants provided was authentic.

It is administered three times daily via a pump dispenser and nasal applicator. In hypogonadal men, the level to which spermatogenesis is impaired depends on both the etiology of hypogonadism and the time of onset pre-pubertal versus post-pubertalsince that affects the baseline testicular volume and the number and functionality of germ cells. Filmann et al.

There appears to be associations between testosterone levels and 25 OH Vitamin D levels and testosterone and phosphate levels [ 7980 ]. An abnormality in males study pituitary hypogonaddism can impair the release of hormones from the pituitary gland to the testicles, affecting normal testosterone production. Sometimes one or both of the testicles aren't descended at birth. Hypogonadism can begin during fetal development, before puberty or during adulthood. The long-term goals of testosterone therapy are to maintain the serum concentrations of sex steroids in the midnormal adult range. View at: Google Scholar I.

Klinefelter syndrome KS is caused by 1 extra X chromosome hypogonadism 12 ]. Given the concerns surrounding the safety and benefits of testosterone therapy in men, other agents have also been used for the treatment of male hypogonadism. Monitoring of testosterone levels starts one month after initiation. Initiation of TRT equivocally is not recommended for men with decompensated congestive heart failure and chronic pulmonary disorders requiring recurrent hospitalization. A recent meta-analysis of the effect of TRT in KS concluded that while TRT could induce improvements in BMD, body composition, and hematocrit, it seems insufficient in normalizing the metabolic profile [ 20 ].

Those data are also in agreement with our results showing no correlation between any lipid fractions and testosterone levels. If a patient using a transdermal formulation of testosterone has no improvement in symptoms, it is reasonable to measure the serum testosterone concentration and adjust the dose as needed to achieve adequate circulating testosterone concentrations.

One untreated KS male had never been treated due to lack of symptoms of androgen deficiency. The theoretical advantages of using DHT gel over testosterone in men would include mainly that a its use does not translate into increased intra-prostatic DHT concentrations and hence the risk of adverse prostate outcomes is lower 18and b it is also not aromatized and hence gynecomastia is not a concern. Monitoring of Serum Testosterone Level.

Still newer therapies, currently in the stages of early clinical trials selective androgen receptor modulatorsmay indeed be the future of androgen replacement therapy and hint at the promise of more benefits than harm, which would simplify these patient discussions and decisions. Clomiphene is a selective estrogen receptor modulator that has weak anti-estrogen action.

In comparison, application of a daily transdermal preparation has been documented to attain and maintain consistent physiologic concentrations throughout the period of application without a significant diurnal variation.

Manufacturers also are required to conduct prospective, randomized, clinical trials with testosterone replacement therapy to address the cardiovascular risks, especially in elderly men with subnormal testosterone concentrations. Replacement therapy includes sex hormone replacement, gonadotropin, and GnRH pulse infusion [ 18 ]. At present, however, there are a number of problems for bioavailable testosterone to become a routine diagnostic tool. If documented, these disorders must be treated appropriately and TRT then may be reinitiated at a lower dose.

Some newer testosterone formulations have recently come to the mapes market. Medications were noted, including the use of hypogonadism in males study abroad, antihypertension drugs, antidiabetic, antidepressant, and antipsychotic medications.
