Hormones have a significant impact on our development. In daily life, we may see that some men's Adam's apple development is not very obvious, which is caused by excessive estrogen. Insufficient secretion of estrogen by women can also affect pregnancy. Some people want to know where to draw blood for the six hormone tests. Let's take a look together.
Where to draw blood for the six hormone tests
When doing the six hormone tests in the hospital, venous blood is usually drawn, and blood is usually drawn from the fingers. In fact, not only the six hormone tests, but other tests also draw blood from this area. It is important to be fasting before drawing blood, otherwise it may cause errors in the test results and require a second blood draw.
What are the six hormone tests
1. Estradiol (E2): E2 is the most active type of estrogen, mainly produced in the follicles and placenta of the ovaries, with a small amount produced in the adrenal glands and testes. Serum E2 measurement is a very useful indicator for evaluating various menstrual abnormalities, such as early or delayed puberty in girls, primary or secondary amenorrhea, premature ovarian failure, etc.
2. Progesterone (P): Female women are mainly produced by the ovaries and placenta. The main function of progesterone is to promote endometrial thickening, glandular hyperplasia, and prepare for the implantation of fertilized eggs. The rise and fall of progesterone concentration can infer the activity of ovarian follicles and corpus luteum, therefore progesterone measurement in blood is clinically used to monitor ovulation and normal function of corpus luteum in non pregnant women.
3. Testosterone (T): T is the most important androgen in the human body. Women mainly come from the adrenal cortex, and the ovaries can also secrete small amounts.
4. Prolactin (PRL): PRL mainly initiates lactation in the human body, causing mature mammary lobules to secrete milk into the glandular cavity.
5. Follicle stimulating hormone (FSH): FSH is secreted by basophils in the anterior pituitary gland and is controlled by luteinizing hormone releasing factor (LHRH) produced by the hypothalamus.
6. Luteinizing hormone (LH): The secretion of LH is controlled by hypothalamic luteinizing hormone releasing hormone (LHRH) and varies with the levels of estrogen and progesterone in the serum.
There are many reasons that can lead to female infertility. After knowing where to draw blood for the six hormone tests, one can go to the hospital for examination to identify the cause and obtain the final solution. If there are no problems with the six hormone tests and other tests for women, it may be due to male infertility, and couples can have a higher efficiency of testing together.
