How to check gynecological endocrine system

The endocrine system of the human body can secrete various hormones, and together with the nervous system, regulates human metabolism and physiological functions.
When the balance of various hormones in the body is disrupted, it leads to endocrine disorders and causes corresponding endocrine diseases.
Endocrinology, especially important for women, is akin to water for fish.
If a woman has endocrine disorders, she may suffer from insomnia and frequent dreams, menstrual irregularities, skin aging, various breast diseases, infertility, etc.
Therefore, in order to timely detect and prevent the progression of endocrine system diseases, it is advisable to undergo an endocrine examination every six months.
What is the procedure for gynecological endocrinology? In the routine gynecological endocrinology examination, when testing androgens, progesterone, estrogens, and follicle-stimulating hormone, 2ml of venous serum is drawn and then separated into blood.
LH is secreted in a pulsed fashion, thus it is preferable to collect blood samples for LH testing at least three to four times within 1 hour. The collected blood should then be mixed before analysis.
The blood test for progesterone should be performed between the 22nd and 24th days of the menstrual cycle. The other five tests are best taken between the 2nd and 4th days of the menstrual cycle.
Before drawing blood, it is best to sit quietly for at least an hour, preferably around 9am in the morning.
What are the gynecological endocrine examinations? The following six items need to be checked: follicle stimulating hormone (FSH) and luteinizing hormone (LH), both secreted by the pituitary gland, mainly promoting follicular development and ovulation. When the detection value is too high, it may be due to amenorrhea or infertility.
Prolactin (PRL), secreted by the pituitary gland, can be elevated due to either a pituitary tumor or hypothyroidism.
Estradiol (E2), secreted by the ovaries, may be elevated due to ovarian tumors or pregnancy, and decreased may indicate hypogonadism or ovarian failure due to other causes.
Progesterone (P) is secreted by the ovaries, and a low level indicates poor pituitary and ovarian function.
Testosterone (T) is also secreted by the ovaries, and when it is too high, it may be due to polycystic ovary syndrome or chromosomal abnormalities.
The price of gynecological endocrine examination is generally around 300 yuan, depending on the region and the hospital where the examination is conducted.
Prices vary by region; at general hospitals, the cost is generally not too high; however, prices tend to be higher at private hospitals or specialty clinics.
Some hospitals also offer inspection packages based on the situation, which are relatively cost-effective and comprehensive.
What should be considered in the interpretation of gynecological endocrine test results? Follicle Stimulating Hormone (FSH): The concentration in the blood is 1.5-10 U/L during the preovulatory phase, 8-20 U/L during the ovulatory phase, and 2-10 U/L during the postovulatory phase.
Low levels are commonly observed during treatment with estrogen, progesterone, and in rare cases of Hirschsprung's syndrome.
Hyperthyroidism is commonly seen in primary amenorrhea, premature ovarian failure, and hypothyroidism.
Prolactin (LH): The concentration in blood is 2-15 U/L before ovulation, 20-100 U/L during ovulation and 4-10 U/L after ovulation.
When levels are below 5 U/L, it is often due to hypogonadotropic function, such as in Hirschsprung's syndrome.
When both follicle-stimulating hormone and luteinizing hormone are elevated, it is often indicative of ovarian failure.
Prolactin (PRL): In non-lactating women, the normal serum concentration is between 0.08 and 0.92 nmol/L.
A serum level above 1.0 nmol/L is suggestive of hyperprolactinemia.
Estrone (E2): The concentration in the blood, 48-52 lpmol/L before ovulation, 370-1835 pmol/L during ovulation, and 272-793 pmol/L after ovulation.
Low levels are often associated with ovarian dysfunction or premature senescence, and may also be seen in cases of Sheehan's syndrome.
P: The concentration of progesterone in the blood, 0-4.8 nmol/L before ovulation and 7.6-97.6 nmol/L after ovulation.
During the luteal phase, a low concentration in blood suggests either a failure of luteal function or a functional uterine bleeding disorder.
Androgen (T): the concentration level of testosterone in female blood is 0.7-2.1 nmol/L, too high called hyperandrogenemia, can cause female infertility.
