How to give testosterone to a woman

For the research, the laboratory worker takes blood from the vein. The biomaterial is obtained under sterile conditions - a doctor's office or an analysis room - with a disposable syringe. In order to objectively assess the patient's condition and make a correct diagnosis, the doctor should be aware of all the circumstances that may somehow affect the results of the analysis.

A woman must tell a laboratory technician or a doctor if she adheres to a non-traditional diet plan( dieting, vegetarianism or raw diet).To come to the laboratory is recommended in advance( for 20-30 minutes), in order to have time to calm down and bring the breath back to normal. Blood from a vein is taken only in the morning and on an empty stomach - 12 hours before delivery it is necessary to completely refuse food, alcohol and smoking.

If the patient does not have the opportunity to come to the laboratory in the morning, the blood should be taken after 6 hours of fasting, eliminating fats from the last meal. The level of hormones can affect the time of year. It is established that the amount of testosterone in the blood rises with the onset of autumn.

Normal in women

The level of sex hormones in girls and women can vary depending on the time of day, the day of the menstrual cycle and age. To determine the level of testosterone, two types of tests are carried out:

  • Analysis of the total level of testosterone in a woman. The test results show how much of the whole hormone is in the body at this stage of life. Norms are considered to be from 0.26 to 1.30 ng / mol.
  • Study of free testosterone. Free is called the type of hormone that does not bind to blood proteins for transportation.

Analysis for the total level of hormones is considered ancillary. It helps to clarify the diagnosis. Particular attention is usually paid to active( free) testosterone. Its reference( normal) parameters for different women of different ages are:

Age of the woman

Minimum values, nmol / l

Maximum values, nmol / l




1-6 years









Over 18 years of age:

follicular phase( 1st to 7th day of the menstrual cycle)






luteal phase



40-59 years



Menopause( over 60 years)



Low testosterone

The doctor analyzes the results of the analysis. It is believed that testosterone in women is lowered if the test showed data below the mean values ​​- less than 0.31 nmol / L( provided that the woman is in reproductive age).Changing the hormonal background in any of the parties is a clear sign of health problems.

Not only women's hormones, estrogen and progesterone, affect male fertility, mood and sexual activity, but also male androgens, especially testosterone. This hormone is produced by the adrenal cortex and is responsible for the maturation of the follicle in the ovaries. In the female body, its level is much lower than in the male. Deviation from the norm can cause violations in the work of different organs and body systems. The blood test helps to identify the discrepancy.
