sex hormone six items, is a routine female reproductive system examination. But what are these six specific? What is the point? When is it appropriate? Most people do not know, today we will introduce in detail.
sex hormone blood collection requirements
1, general recommendations: menstrual period 2-5 days blood test, the best third days.
2, long-term amenorrhea: can be detected at any time when necessary, B ultrasound examination, examination results will serve as a basis for state level.
3, the factors that should be avoided before blood transfusion: breast stimulation, sexual life, mental stress, the use of estrogen and progesterone, some of the spirit and antihypertensive drugs.
follicle stimulating hormone (FSH)
FSH is a glycoprotein substance secreted by the anterior pituitary gonadotropin cells regulated by mediobasal hypothalamus gonadotropin releasing hormone, a pulsatile secretion, rapid fluctuations in the normal range, the amplitude is less than the luteinizing hormone (LH).
FSH can regulate the growth, development, reproduction and adolescent sexual maturity is related to a series of physiological processes, promote follicular development and maturation; FSH varies with the periodic change of E2 and P, with LH secretion peak of the menstrual period, FSH will show a small but significant increase; luteal phase, FSH with the formation of corpus luteum in the process of the formation of E2 and P decreased.
in menopause or after ovariectomy and ovarian function decreased with decreased E2 secretion, while FSH and LH was increased and E2 feedback inhibition to decrease of gonadotropin release.
Clinical significance of
is common in menopause, premature ovarian failure and ovariectomy, hypothalamus and pituitary gonadotropin secretion of ovarian tumor, insensitivity syndrome and primary amenorrhea.
FSH> 15mIU/mL: poor fertility;
FSH> 40mIU/mL: clinical manifestations of ovarian failure.
can be seen in the oral contraceptives or estrogen and progesterone treatment; FSH concentration may also indicate that the hypothalamus pituitary axis dysfunction, in sexually mature adults, FSH deficiency and other sex hormone concentrations decreased;
