In order to care for women’s physical health, today we recommend the Sex Hormone 6 test to all women. Sex hormone levels are measured to understand female endocrine function and to diagnose diseases related to endocrine disorders. The commonly used sex hormone tests, namely follicle stimulating hormone (FSH), luteinizing hormone (LH), estradiol (E2), progesterone (P), testosterone (T), and prolactin (PRL), basically satisfy the clinical screening of endocrine disorders and general understanding of physiological functions. FSH and LH are closely related to the growth of gonadal tissue and the control of reproductive activity. FSH rises during menopause, after oophorectomy and in premature ovarian failure. polycystic ovarian disease. Ovarian decline is suggested by FSH concentrations above 40 mu/ml when measured randomly. In men, vas deferens growth as well as maintenance of sperm production is often regulated by FSH, and FSH levels are usually elevated in men with azoospermia and oligospermia. Elevated FSH is also seen in primary testicular failure and fine duct hypoplasia (i.e., klinefelter syndrome), starvation, renal failure, hyperthyroidism, and cirrhosis; whereas testicular tumors generally have reduced FSH concentrations. Luteinizing hormone (LH). elevated LH concentrations are seen in hypogonadism, primary testicular failure and fine duct hypoplasia, renal failure, cirrhosis, hyperthyroidism, and severe starvation. Inadequate secretion of anterior pituitary hormones can cause reduced LH levels. Low LH levels in both men and women can lead to infertility, and low LH values can indicate some dysfunction of the pituitary or hypothalamus. LH concentration is routinely measured in the differential diagnosis of hypothalamic, pituitary or gonadal dysfunction, and is measured together with FSH. In addition, LH is used to determine menopause, the timing of ovulation, and to monitor endocrine therapy. Estradiol (E2). Serum E2 measurement is a very useful indicator for the evaluation of various menstrual abnormalities: early or delayed puberty in girls, primary or secondary amenorrhea, premature ovarian failure, etc. In men, E2 is also elevated in the presence of feminization syndrome, breast feminization, and testicular cancer. The monitoring of serum E2 in patients with infertility is very useful to monitor ovulation induction and subsequent treatment. In in vitro fertilization (IVF), the use of chorionic gonadotropin and the collection of oocytes are usually optimally adjusted daily during overstimulation of the ovaries, and E2 concentrations also need to be measured. Testosterone (Testoserone, T). Measurement of serum Testo in men helps in the diagnosis of testicular dysfunction. Measurement of serum Testo in women is useful in the evaluation of hirsutism, hair loss and menstrual abnormalities. Progesterone (Prog, P). Prog concentration is measured to determine the presence or absence of ovulation and luteal function in infertile women. The best time to check endocrine is on the 3rd-5th day after menstruation, which is the early follicular period and can reflect the functional state of the ovaries. However, for those who are not menstruating for a long period of time and are eager to know the results of the test, the test can be performed at any time, which is by default the time before menstruation, and the results will be based on the results of the luteal phase test.
