What are Androgens?
Androgens are the sex steroids or hormones that produce changes in body shape (muscle gain, fat distribution) and secondary sexual characteristics (hair and beard growth, penile growth) typical of men. Androgens play a major and essential role in reproductive and sexual function in the mature male. The most important androgen in men is testosterone.
What are Steroids?
The synthetic derivative of androgens (male sex hormones) are commonly referred to as 'anabolic-androgenic steroids'. (Street name: 'roids').
Anabolic effects include the promotion of skeletal muscle growth
Androgenic effects refer to the development and maintenance of male sexual characteristics
When are Androgens misused or abused?
The medical misuse of androgens may occur in such settings as male infertility, male sexual dysfunction and 'male menopause'.
There is no good evidence to show that testosterone treatment is effective and safe for older men where androgen deficiency has not been clinically proven. Until further evidence is available, such treatment can not be recommended.
In the wider community, misuse of androgens in sport is also an issue with some athletes using androgens outside the rules of their particular governing body and without knowledge of the long-term affects on the body. Disqualification may occur if androgens are used in this setting.

Testicular causes:
Classical androgen deficiency
Testicular disorders
Klinefelter’s syndrome and variants (mosaic)
Cryptorchidism and defects of testis development
Orchitis
Orchidectomy (advanced prostate cancer, bilateral testicular cancer)
Toxin exposure (cancer chemotherapy or radiotherapy, environmental, occupational and domestic toxins)
Pituitary causes
Hypothalamic–pituitary dysregulation
Idiopathic hypogonadotropic hypogonadism and variants:
Kallmann’s syndrome (associated with anosmia and midline cranial defects; caused by mutations in the KAL1 or FGRF1 [fibroblast growth factor receptor 1] genes)
Other genetic causes (including inactivating mutations in the DAX-1 [adrenal hypoplasia congenita], GnRH-receptor or GPR54 [G protein-coupled receptor] genes)
Pituitary tumour and treatment (surgery, irradiation)
Haemochromatosis
Craniopharyngioma
Partial or transient androgen deficiency

The rational , efficacy and safety of androgen therapy in
older men
UNDER PHYSICIAN SUPERVESION
Background. Studies revealed normal aging associated with decline in
testosterone. Result in feature similar of deficiency in young. Age related androgen deficiency truly cause these feature need
studies. Androgen treatment safe as aged tissue not remain androgen
sensitive. Studies showed androgen increase muscle bulk and reduce fat. Side effect such sleep disturbances, breathing problem or
Polycythemia dose responsive. Cardiovascular and prostate safety uncertain. Supplementation in healthy old men not recommended. Symptomatic older men with low level need to follow the
recommendation to avoid unnecessary prescription.
Facts.
Number and proportion of men above 60 years will increase in the coming 50 y.
Safe and effective medical intervention to promote healthy aging are therefore valuable.
Hormone therapy is promising and inexpensive and androgen has anabolic effect.
Androgen use in elderly patients need study to evaluate the efficacy and safety.

Muscle, fat, and bone. Nine studies for 3 months or more in patients with low T reporting
effect on the muscle and fat. Standard replacement doses except one supraphysiological dose
used. Titrated to have normal T level. 1.5-2.5 kg reduction in fat mass and increase in muscle mass by 1-2
kg. Analysis of the studies revealed no significant changes of muscle or fat
masses after 6 months of the treatment. Whether such changes persist with long term administration. Significant improvement not demonstrated and if present likely to be
small. Muscle strength increased by 3% with androgenic supplement that
double the basal T. It remain unclear if small increment in muscle strength will improve the
daily living for frail older men.
Insulin sensitivity.
T may improve intraabdominal fat which reduce the insulin resistance.
Low serum T predict the development of type 2 diabetes.
Effect of androgen supplement on the BMD
Increased but depend on the duration and the dose.
Current recommendation.
Total T concentration less than 200 ng/dl (8nmol/l) indicate overt deficiency.
Level 200 – 400 ng/dl (8-15nmol/l) possible deficiency.
Above 400 exclude androgen deficiency. LH, FSH, SHBG, Free T needed in case border line level in
symptomatic patients.

Mood and cognitive (higher mental) function
•irritability and tiredness
•decreased sense of well-being
•lack of motivation
•low mental energy
•difficulty with short-term memory
•depression
•low self-esteem
•being easily frightened.
Masculinity and virility
•decreased vigour and physical energy
•diminished muscle strength.
Sexuality
•decreased interest in or desire for sex
•less sexual activity
•poor erections
•reduced quality of orgasm
•weakness of ejaculation
•reduced volume of ejaculated fluid.
Physical features include
•diminished muscle mass
•loss of body hair
•abdominal obesity.
Several other effects on body chemistry and metabolism occur, such as:
•reduction in high-density lipoprotein (HDL) cholesterol and increase in low-density lipoprotein (LDL) cholesterol, which increases the risk of developing coronary artery disease.
•increase in total body fat (because of a fall in the proportion of body weight that is muscle rather than through weight gain).
•osteoporosis (a change in bone structure and strength that predisposes the sufferer to fractures, particularly of the wrist, hip and spine).
•reduction in red cell volume (a reduction in the proportion of red blood cells to plasma.
What are the consequences of androgen deficiency (PADAM)?
Changes caused by PADAM could potentially affect health in several ways:
•increased risk of osteoporotic fracture and cardiovascular disease
•reduced general well-being
•depression.
•cognitive impairment (problems with thought, concentration and memory).
•reduced physical strength
•sexual problems.
Misuse of androgen.
Male infertility. Impotence. Andropause. Elderly men. Treatment of non specific symptoms.
Androgen deficiency is a clinical diagnosis confirmed by hormone assays.
1) Among younger men, androgen deficiency is usually due to underlying hypothalamopituitary or testicular disorders.
2) Androgen replacement therapy should be started after proof of androgen deficiency and should continue lifelong with monitoring.
3) Men presenting with erectile dysfunction should be evaluated for androgen deficiency, but it is an uncommon cause; if overt androgen deficiency is confirmed, an underlying disorder needs further specialist investigation.
4) In the absence of characteristic underlying testicular or pituitary disorders, new diagnosis of androgen deficiency in older men is difficult because of the non-specific symptoms and the decline in blood testosterone levels seen in healthy ageing and chronic medical disorders.
5) There remains no convincing evidence that androgen therapy is either effective treatment or safe for older men unless they have frank androgen deficiency.
6) While androgen replacement therapy is essential and effective in overt deficiency, it is no anti-ageing elixir.
