Estradiol: exam evaluates changes in uterus, fallopian tubes and breasts

Estradiol: exam evaluates changes in uterus, fallopian tubes and breasts

The estradiol test measures the levels of this hormone in the blood. Estradiol is a type of estrogen whose body concentrations vary according to the menstrual period in women. After menopause, estradiol levels fall and become constant.

In women who have not reached menopause, the menstrual cycle causes changes in the production of various hormones. The menstrual cycle is divided into follicular and luteal phases, with each phase lasting about 14 days. Near the end of the follicular phase, there is an increase in the hormones FSH and LH. This increase induces ovulation, causing the follicle to rupture in the ovary to release the egg.

During the luteal phase, the site where the follicle ruptured transforms into the corpus luteum. FSH and LH levels decrease, while progesterone and estradiol concentrations increase. These hormone levels, in turn, decrease after several days if the egg is not fertilized. Menstruation then begins and the cycle is renewed.

As the age progresses, the ovarian function decreases until the onset of menopause. When this occurs, estradiol and progesterone levels decrease.

Men also produce estradiol, but smaller amounts. Male estradiol is produced in the adrenal glands and testes. It is a hormone that contributes to fertility and libido in men.

Indications

In women, most of oestradiol is released by the ovaries and adrenal glands. It is also released by the placenta during pregnancy. Estradiol plays a role in factors such as:

  • Development of the uterus, fallopian tubes, vagina, and breasts
  • Changes in external genitalia
  • Distribution of body fat

In men, a small amount of estradiol is released primarily by testicles. The hormone helps to prevent sperm from dying too early.

The oestradiol test can be ordered to check:

  • Ovary, placenta or adrenal gland function
  • Signs of ovarian cancer
  • Menopause or early menopause
  • Menstrual changes such as lack of menstrual periods (amenorrhea), infertility and abnormal vaginal bleeding
  • The development of the follicle in the ovary in the days before in vitro fertilization
  • Signs of early puberty

The test can also be ordered to monitor hormone therapy for menopause, antiestrogen therapy for diseases such as breast cancer or the functioning of fertility treatments. Finally, the estradiol test can be used to monitor people with pituitary gland disorders.

Contraindications

There are no express contraindications to an oestradiol test. However, the doctor or doctor can tell you whether you are fit to take the test or not.

Pregnant can do?

There are no contraindications to undergoing the estradiol test during pregnancy. In addition, the test can be performed to keep track of various conditions in the period.

Exam Preparation

Several medications may change the test results. Write down all the medicines you take regularly and take it to the office, including food supplements. Your doctor will tell you if you should stop taking any medication and for how long.

The oestradiol test is usually done by the fifth day of the menstrual cycle. Talk to your doctor about the best time to take the test.

How it is done

In a hospital or laboratory, the oestradiol test is performed by a healthcare professional as follows:

  • With the patient sitting, a rubber band is tied around his arm to stop the flow of blood. This causes the veins to become wider, helping the practitioner to hit one of them
  • The professional cleans the area of ​​the arm to be penetrated by the needle.
  • The needle is inserted into the vein. This procedure can be done more than once until the health care provider hits the vein and is able to remove the blood.
  • Blood collected in the syringe and placed in a tube
  • The elastic is removed and a gauze is placed on the where the health professional inserted the needle, to prevent any bleeding. He or she can put pressure on the bandage to staunch blood
  • A bandage is placed on the spot

Blood test: know the path your blood takes after collection

Examination time

The examination of estradiol takes a few minutes to be performed, and may take longer in cases where the healthcare professional has difficulty hitting the vein and collecting blood.

Post-examination recommendations

There are no special recommendations after the procedure. exam. The patient can perform his / her activities normally.

Frequency of the test

There is no periodicity for the dosage of estradiol. It will depend on the physician's guidance and the presence or absence of problems that may be accompanied by the test, such as infertility.

Risks

The risks involved in performing the estradiol test are extremely rare. At most, there may be a hematoma at the site where blood was withdrawn. In some cases, the vein may become swollen after the blood sample is collected (phlebitis), but this can be reversed by making a compress several times a day.

People who use anticoagulant medications or have coagulation problems may suffer from a bleeding after collection. In these cases, it is important to inform the health care professional of the problem in advance.

Results

The interpretation of the estradiol test depends on the reason why it was required. It is therefore important to take into account factors such as presence of pregnancy, menstrual cycle, age, and hormone replacement therapy.

Normal results

The reference values ​​shown here are just a guide, a instead of switching from laboratory to laboratory. In addition, the physician or physician will evaluate the results according to the patient and their characteristics, such as age and related diseases.

Estradiol levels are measured in nanograms (ng) per liter of blood (L).

Normal progesterone results may vary according to the menstrual period. In females, the values ​​are:

  • Follicular phase: 1.3 to 16.6 ng / dL (46 to 607 pmol / L)
  • Ovulatory peak: 8.6 to 49.8 ng / dL (315 (up to 201 pmol / L)
  • Menopause: up to 5.5 ng / dL (up to 201 pmol / L)
  • Luteal phase: 4.4 to 21.1 ng / dL (161 to 774 pmol /

In males, the progesterone dosage considered healthy is 0.8 to 4.3 ng / dL (28 to 156 pmol / L).

Children 1 to 10 who have not yet reached the puberty stage should have the following estradiol values:

  • Male gender: up to 2.0 ng / dL (up to 73.4 pmol / L)
  • Female sex: 0.6 to 2.7 ng / dL (22 to 99 , 1 pmol / L)

Abnormal results

Levels of estradiol above normal in females may indicate:

  • Early puberty
  • Ovarian or adrenal gland cancer

Oestradiol levels above normal in the male sex may indicate:

  • Gynecomastia
  • Cancer in the testis or adrenal glands
  • Puberty delayed

In general, increased levels of estradiol can Low levels of oestradiol (female hypogonadism)

  • Hyperthyroidism
  • Cirrhosis

Low levels of estradiol in women may indicate:

  • Turner syndrome
  • Low level of pituitary hormones (hypopituitarism)
  • Eating disorders, such as anorexia nervosa
  • Menopause
  • Polycystic ovarian syndrome
  • Excessive physical activity

What may affect test result

Factors that may affect test result estradiol include:

  • Hormone therapy after menopause
  • Contraceptive use
  • Use of some medications, which may be listed by the doctor
  • Day of the menstrual cycle

GH: Benefits of the hormone and how to increase production naturally

GH is a growth hormone and is present in all people. Also known as somatropin, HGH or GH (Human Growth Hormone), growth hormone is a highly anabolic (essential for muscle gain) protein synthesized by the pituitary gland. It is essential for a number of metabolic processes and the growth of various tissues - among them the muscular.

Breast pain may be related to menstrual cycle and pregnancy

Breast pain may be related to menstrual cycle and pregnancy

More than 50% of women have experienced some type of breast pain (also called mastodynamic or mastalgia) at some point in their lives. Usually the pains are bearable - however, in about 10% of cases breast pain can be disabling in some way. In addition to women, men may also experience breast pain. To understand better, it is necessary to know that breasts are made up of hormone-sensitive tissues, and changes in these levels may occur throughout life.
