Regular delivery of analyzes on hormones in men allows time to detect disease, emerging from the endocrine system. Hormonal disorders can provoke atherosclerosis, obesity and diabetes. The emergence of anxiety symptoms (partial or total alopecia, rash) in men is the occasion to take a blood test for hormones.
Indications for testing purpose
Studies to check the hormonal status (male), assigns a therapist. Pituitary (brain appendage) is responsible for the formation of normal reproductive system adolescents and their growth. Its dysfunction leads to insufficient production of prolactin, TSH, FSH and LH. The test for the hormones necessary to hand in the following cases:
- suspicion of malignant or benign tumors;
- decreased potency;
- infertility (provided that does not use a male contraceptive for 12 months);
- gynecomastia (an increase and breast tenderness);
- adiposity (fat rollers are formed in the hips and waist);
- stunting (adolescence);
- delayed puberty.
If a teenager boys did not show the characteristic signs of ripening (increase of the penis and testicles, appearance stiff bristles on the face, muscle growth), the expert assigns examination, which allows to identify hormone status. Infertility, in addition to blood tests, a man must pass semen analysis.
How to prepare
On the analysis parameters can affect third-party factors. It is important to properly prepare for blood donation. Therapists recommend:
- abandon the use of tobacco products in a few hours prior to analysis;
- avoid stressful situations during the day before the blood donation;
- stop drinking for 2 days before blood sampling;
- completely excluded from the diet of salty, sour, fatty and smoked foods the day before blood sampling;
- avoid physical fatigue within 3-4 days (including the day of delivery of blood);
- stop taking the medication.
If a man medicines have been designated, receiving interrupt the course of which is prohibited, it is advisable to transfer the day of delivery of analyzes. Blood sampling is carried out on an empty stomach.
As for tests
The analysis on hormones for men sit in the morning. Before the procedure, the patient is allowed to drink non-carbonated mineral water. Other drinks (tea, coffee, energy and silnogazirovanny lemonade) - banned. Blood is drawn from a vein, abstracted paramedic or nurse. The patient should sit or lie down on the couch. If he is worried, the doctor puts a procedure for 5-10 minutes, the patient was able to calm down.
The blood can be taken from a vein:
- an outer surface;
- median cubital;
- ray;
- median surface;
- ulna.
Blood vessels listed above are inactive due to the tendons.
If you take blood from a vein on the back of the hand, then the procedure will be more painful.
After the sampling site was found, the nurse starts the procedure:
- The injection site is wiped with cotton wool dipped in alcohol.
- Just above the elbow arm pulls harness.
- Sterile needle to pierce a vein, introducing it at an angle of 45 ° in the third.
- Remove the tourniquet.
- Conduct sampling of biological material (slowly).
- Take out the needle clamp with an alcohol swab the injection site.
After the procedure, the patient flexes the elbow. Paramedic sends the material to the laboratory.
Norm and deviation
Norms of hormone in men are presented in the table below:
| Title | Indicators |
| LNG (binding sex hormones) | 15-65 nmol / l |
| Progesterone | 0,34-0,60 nmol / l |
| estradiol | 17-62 pg / mL |
| prolactin | 2,6-16 ng / ml |
| luteinizing hormone | 3-9 mU / l |
| Testosterone | 340-940 ng / dl |
| dihydrotestosterone | 260-980 pg / ml |
| follicle-stimulating hormone | 1,38-13,57 mU / l |
Any fluctuations to increase or decrease the performance is considered to be deviations from the norm.
Testosterone
The hormone belongs to the androgen steroids. Testosterone is produced testes and adrenal glands. Distinguish 2 basic types:
- Connected. The percentage ratio - greater than 98%. Using the proteins of the active ingredients into the body.
- Active. The male body is present 2% of these hormones. Freely penetrate inside cells, moving freely on the bloodstream.
hormone level depends on the following factors:
- age;
- time of day;
- season.
The synthesis process is started in adolescence (14 years). During puberty due to testosterone voice breaks in boys, increases muscle mass and sex organs are developing.
FSH
Formulation hormone responsible for fertility, carried by the pituitary gland. The normal level of FSH is responsible for the appendages, testicles and intensification of spermatogenesis. A man should be tested for FSH for suspected infertility. Deviation from the norm may indicate:
- about obesity;
- the exhaustion;
- overdose of steroids or anabolics;
- of pituitary dysfunction.
If the hormone level is high, the risk of developing benign or malignant tumor in the pituitary gland is quite high.
prolactin
Another hormone responsible for a man's ability to conceive. Generation takes place in the pituitary gland. Under the influence of prolactin occurs immunity stimulation, the formation of secondary sex characteristics (in adolescents) and the regulation of spermatogenesis. Increased blood levels of the hormone can be caused by:
- prolonged antidepressant;
- Thyroid disorders work;
- abuse of a protein food;
- exhaustion;
- insomnia;
- physical exhaustion.
Hyperprolactinemia provokes the development of obesity, osteoporosis, depression and infertility.
dihydrotestosterone
DHT is involved in the development of sexual organs and is responsible for the erection. Testosterone is produced.
Lack of androgen production leads to a partial or total alopecia (hair loss).
In adolescents, there are anomalies in the structure of the genitalia. Figure men in the body where the concentration of DHT is small, it becomes more feminine fat is deposited on the hips and the sides.
Lowering blood levels of the hormone can trigger the following factors:
- aging;
- alpha-reductase deficiency;
- long-term use of medicines;
- failure of the testes.
pass a blood test to identify the exact causes hormone deficiency.
estradiol
Despite the fact that estradiol plays a large role in shaping the female body, men are often prescribed this study to determine the hormonal status. A minor part of the hormone produced by the adrenal cortex, the main - enters the bloodstream of the body fat. In men, excess weight testosterone concentration is lowered, and estradiol - increased.
Female sex hormone responsible for blood coagulation, is involved in metabolic processes and the development of seminal fluid. Reduced estradiol concentrations most often caused by physical exhaustion and malnutrition, alcohol abuse and tobacco. Before any analysis is necessary to temporarily stop an intimate relationship with a partner.
To raise hormone levels to help a balanced diet. The diet is necessary to include dairy products, red meat and eggs.
SHBG
SHBG (globulin, sex hormone binding) is responsible for the normal functioning of the reproductive function in men. No effect on the fabric, and it has no buds. The biological activity is low, so androgens indestructible. shortage free testosterone It leads to premature aging of the organism. The muscles become flabby, the skin loses its elasticity.
Key features reduce the concentration of SHBG:
- fast fatiguability;
- reduction in the body's reactions;
- cessation of muscle growth;
- lack of erection;
- seborrhea;
- the appearance of pustules on the back, neck and face;
- decreased libido;
- obesity;
- prostatitis (chronic, with occasional relapses).
If the blood levels of SHBG men increased, the risk of tumors in the prostate gland grows. To normalize the concentration of globulin, experts recommend eating foods fortified with vitamins and minerals (D, A. E, zinc, magnesium, boron).
The cost of delivery of analyzes
Cost Analysis on the male hormones can vary depending on what kind of research center of the patient chose. on the procedure for price increases, if the man decided to remain anonymous or call a specialist at the house. Many laboratories offer social discounts. The cost may depend on the speed of analysis. In Moscow and other Russian cities the price of hormonal research ranges 700-1500 rubles.
