On what day of the cycle to take female hormones, when the blood is better at sex, which analyzes on gynecology need 3, 5, monthly, table

Hormones in women varies with the menstrual cycle. This fact should be considered if the patient is scheduled diagnostic examination. Gynecologists know what day of the cycle to take female hormones. Therefore, the test results in most cases are correct.

As the month can affect hormone levels

Fluctuations in hormonal levels:

1. From 1 to 7 day - a low level of estrogen.
2. From 8 to 14 days - rising levels of progesterone and estrogen.
3. From 15 to 21 days of progesterone synthesis occurs growth and estrogen concentration gradually decreases.
4. From 22 to 28 day falls sharply the level of sex hormones. The woman in this period feel symptoms of premenstrual syndrome.

What hormones pass during menstruation

Menstruation can not be considered a contraindication for taking tests. But a woman should alert the physician that she started menstruating. This is necessary to ensure that maximum accuracy decipher the test results. The first few days of the menstrual cycle is considered the best time to donate blood at the level of female hormones. During this period, alternately increase their concentration.

About reproductive system status and availability of gynecological diseases doctor judges by the maximum rate of hormonal levels. When the concentration reaches the highest limits, the exceeding readily determine the level of these substances, or conversely, the lack of them. During menstruation pass tests for pituitary hormones.

prolactin

Increasing the level of prolactin in the first phase of a cycle can cause sexual dysfunction. Its main effect of the substance has on the mammary gland, stimulating their growth, increases the production of breast milk and reduces the production of sex hormones. Normally, excess prolactin indicators may occur during sleep, after strenuous exercise during pregnancy (since 5 weeks before delivery) and during lactation. Your doctor may recommend to give blood for determination of prolactin in the second phase of the cycle. It is necessary for the diagnosis of certain hormonal disorders.

FSH

Follicle-stimulating hormone is involved in the normalization of the function of sexual glands. It has a direct effect on the ovaries. Thanks to FSH is the development of follicles, increased synthesis of estrogen, mature egg. By reducing its level of impaired reproductive function of women.

The synthesis of FSH affect estrogen levels. The higher their secretion, the lower the concentration of FSH. Conversely, reduction of estrogen synthesis entails raising FSH. In addition, the performance depends on the following factors:

• phase of the menstrual cycle;
• age and hormonal activity (menopausal FSH level increases 10 times);
• pregnancy (abrupt decrease);
• physical exercise;
• frequent stressful situations;
• starvation;
• abuse of alcohol and nicotine;
• total intoxication chemicals or drugs.

LH

Luteinizing hormone also affects the ovaries to stimulate ovulation, follicle transforms into the corpus luteum, and participates in the synthesis of progesterone. LH surge observed in ovulation and also in a second phase of the menstrual cycle. On LH affect hormonal activity by women. In reproductive age indicators peak at ovulation period, and by the end of the first phase of the menstrual cycle are reduced to a minimum.

During pregnancy decreases the synthesis of LH, and during menopause increases. Fluctuations LH concentrations can be triggered by stressful events, intoxication, nicotine abuse, and liquor.

Which days of the cycle take

If you know exactly how to change hormones by day cycle, you can get the most accurate analysis results.

The table lists the recommended period, which can be tested for female hormones.

Hormone	when should I take
prolactin	3-5 day cycle
luteinizing hormone	3-5 day
follicle-stimulating hormone	3-5 day
estradiol	The second phase of the cycle. The best thing on the seventh day after ovulation.
Progesterone	The second phase of the cycle (day 21-23)
Androgens (Testosterone)	On the eighth day of the cycle

In the first phase of the menstrual cycle the minimum level of prolactin. A gradual increase in rates - after ovulation. At different times of the day there is fluctuation in hormonal levels. Maximum growth rates observed during the night. Reduction begins between five and seven o'clock in the morning. These features are taken into account when scheduling delivery of analyzes.

The first and second phase of the cycle to be tested for hormones in women can be reused. This need arises in the case of violations, requiring additional diagnosis.

What time of day

In order to obtain reliable results, you need to be tested at the right time.

It is best to perform blood sampling in the morning on an empty stomach.

If this is not possible, you can be tested for the female hormones in the evening. But if after the last meal came to less than 8 hours, the performance will not be accurate.

How to prepare

It is impossible to be tested for hormones in gynecology without preparation. They will be received invalid data and this will affect the correct diagnosis.

1. 72 hours prior to analysis on luteinizing hormone needed to completely eliminate the physical activities and sports. For 1-1.5 hours. up blood sampling should give up smoking.
2. Letting analysis progesterone produced in the 21-23 day cycle. The best time for blood collection - morning. After the last meal should take at least 12 hours. On the eve of the analysis can not eat fatty foods. If a woman uses drugs that affect hormones, then it should be reported to the attending physician.
3. 24 hours before the delivery of the analysis on prolactin eliminate sexual contact, and you can not take a hot bath, a sauna and drink alcohol. One hour prior to blood sampling is non-smoking.
4. Analysis of androgens pass in the morning, on an empty stomach. After the last meal must pass 10-12 hours. To get the right result, it is necessary to exclude the use of fruit juices, tea and coffee with sugar. For a more accurate diagnosis of androgen levels is needed to test SHBG (binding globulin sex hormones). Its concentration depends testosterone levels in women.

Terms of delivery

Immediately before the procedure can not be nervous. Even the slightest stress can cause fluctuation in hormone levels. Before taking blood woman should sit down on a chair, take a few deep breaths to relax and calm down.

Blood tests for pituitary hormones (LH, FSH and prolactin) can be carried out twice a month. First blood to pass 3-5 day cycle, followed by 6-8 days after ovulation. This will help to determine the maximum and minimum values.

Donate blood for hormones should be in specialized laboratories, where have all the necessary equipment for the study of biological material and subsequent decryption performance.

If it is correct to take a blood sample, it is possible to timely detect hormonal disorders and begin its correction.
