Treatments of hypogonadism depend on the cause.  
Patients with hypogonadism are treated mainly with [[sex hormones]] replacement. [[Sex hormones]] will help in retaining the [[secondary sexual characteristics]] for both genders. They will also help in maintaining normal [[bone density]] and [[muscle mass]]. The main medical therapy in males will be [[testosterone]] replacement.

==== Testosterone replacement therapy ====
* Based on endocrine society clinical practice guidelines, [[testosterone]] replacement therapy is the mainstay of treatment in patients with hypogonadism.<ref name="pmid20525905">{{cite journal| author=Bhasin S, Cunningham GR, Hayes FJ, Matsumoto AM, Snyder PJ, Swerdloff RS et al.| title=Testosterone therapy in men with androgen deficiency syndromes: an Endocrine Society clinical practice guideline. | journal=J Clin Endocrinol Metab | year= 2010 | volume= 95 | issue= 6 | pages= 2536-59 | pmid=20525905 | doi=10.1210/jc.2009-2354 | pmc= | url=https://www.ncbi.nlm.nih.gov/entrez/eutils/elink.fcgi?dbfrom=pubmed&tool=sumsearch.org/cite&retmode=ref&cmd=prlinks&id=20525905  }}</ref>
* Indications of testosterone therapy are as the following:
** [[Testosterone]] is indicated for replacement therapy in adult males for conditions associated with a deficiency or absence of endogenous [[testosterone]].
*** Primary hypogonadism (congenital or acquired): Testicular failure from conditions such as [[cryptorchidism]], [[Testicular torsion|bilateral torsion]], [[orchitis]], vanishing [[testis]] syndrome, [[orchiectomy]], [[Klinefelter syndrome]], [[chemotherapy]], or [[toxic]] damage from [[alcohol]] or heavy metals. These men usually have low serum [[testosterone]] concentrations and [[gonadotropins]] ([[follicle-stimulating hormone]] [FSH], [[luteinizing hormone]] [LH]) above the normal range.
*** Hypogonadotropic hypogonadism (congenital or acquired): Idiopathic gonadotropin or [[luteinizing hormone-releasing hormone]] (LHRH) deficiency or [[Pituitary gland|pituitary]]-[[hypothalamic]] injury from [[tumors]], [[trauma]], or [[radiation]]. These men have low [[testosterone]] serum concentrations but have [[gonadotropins]] in the normal or low range.
** Limitations of use:
*** Safety and efficacy of [[testosterone]] in males less than 18 years old have not been established.
* Testosterone therapy is contraindicated in the following cases:
** [[Breast carcinoma]]
** [[Prostate cancer]]
** Patients with [[hematocrit]] value more than 50%
** Untreated [[obstructive sleep apnea]]
** Severe [[Urinary tract infections|lower urinary tract infections]]
** [[Heart failure]]
* In this table, the different recommended regimens of testosterone administration are discussed.

==== Estrogen replacement therapy ====
* Indications: treatment of [[hypoestrogenism]] due to hypogonadism, [[castration]], or [[primary ovarian failure]].
* Dosing information: oral tablet, 1 to 2 mg daily; [[titrate]] and adjust to the lowest dose as necessary to control symptoms.
* Contraindications:
** Undiagnosed abnormal genital [[bleeding]]
** Known, suspected, or history of [[breast cancer]]
** Known or suspected estrogen-dependent [[neoplasia]]
** Active [[DVT]], [[Pulmonary embolism|PE]], or a history of these conditions
** Active [[arterial thromboembolic disease]] (for example, [[stroke]] and [[ST elevation myocardial infarction|MI]]), or a history of these conditions
** Known [[anaphylactic reaction]] or [[angioedema]] with [[Climara]]
** Known liver impairment or disease
** Known [[protein C]], [[protein S]], or [[antithrombin deficiency]], or other known [[thrombophilic disorders]]
** Known or suspected [[pregnancy]]


:*For hypogonadism resulted from certain autoimmune disorders or [[infection]] in sex glands, treatment protocol may focus on these causes and [[corticosteroids]] or [[antibiotic]]s may be helpful. When [[tumor]]s in [[central nervous system]] are the main causes of hypogonadism, treatment opinion may be [[surgery]], [[radiation therapy]] and [[chemotherapy]]. If liver and kidney diseases result in hypogonadism, recovery of liver and renal function may be the first.
:*Hormone replacement: Hormone replacement for patients with hypogonadism during childhood can stimulate puberty and the development of secondary sex characteristics. Hormones often used include [[estrogen]] or [[testosterone]], and pituitary hormones. Doctors will begin with an initial low dose of such hormones and gradual increases to avoid [[side effect]]s.
:*Hypogonadism is most often treated by replacement of the appropriate hormones. For men this is [[testosterone]]. Commonly used testosterone formulations include  transdermal testosterone, injectable testosterone, and buccal testosterone. Oral testosterone is no longer used in the U.S. because it is broken down in the liver and rendered inactive. 
Another feasible alternative is [[hCG]].
For women [[estradiol]] and [[progesterone]] are replaced. Some types of fertility defects can be treated; some cannot.

Overview

The mainstay of therapy for hypogonadism is the hormonal replacement therapy. Based on the endocrine society clinical guidelines, testosterone is important for the treatment of hypogonadism. Different regimens include injected, buccal and transdermal testosterone. For women, estrogen replacement therapy is important besides testosterone.[1]

Medical Therapy

Patients with hypogonadism are treated mainly with sex hormones replacement. Sex hormones will help in retaining the secondary sexual characteristics for both genders. They will also help in maintaining normal bone density and muscle mass. The main medical therapy in males will be testosterone replacement. In the females, estrogen replacement is important besides testosterone.[1]
