Check the polycystic ovary syndrome, polycystic ovary syndrome should be how

polycystic ovary syndrome should be how?

diagnostics including real inspection typical of PCOS, the so-called Stein-Leventhal syndrome, diagnosis, clinical course who should make the necessary common atypical experimental examination and ovarian pathology.

A hormone test

(a) gonadotropin: LH increased about 75% of patients, PSH normal or reduced, LH / FSH ≥ 3.

(b) of the steroid hormone

1, male hormones, including testosterone, dihydrotestosterone, the male and 17 thin-dione steroid ketones increased, so as to reduce the free-state SHBG androgen increased.

2, total estrogen up to 140pg/ml, the early follicular levels of male-diol equivalent of about 60pg/ml, extragonadal estrone increased production so that E1/E2 ≥ 1.

3, increased production of adrenal DHEAS, plasma concentrations of ≥ 3.3μg/ml, 17-hydroxy progesterone also increased (normal laparoscopy, in order to impose direct observation of ovarian morphology or biopsy, puncture, cut and electrocautery wedge other treatment.

two, CT and magnetic resonance

except to identify and pelvic tumors.

three laparotomy

to be diagnosed ovarian cancer or ovarian wedge cut like the line when implemented.

1.LH/FSH and blood concentrations of LH and FSH ratio were abnormal, showing non-cyclical secretion of LH increased in most patients, but the equivalent of the early follicular phase FSH levels, LH / FSH ≥ 2.5 ~ 3, many scholars that the LH / FSH ratio increase is characteristic of PCOS.

2. male steroid androgen excess, testosterone, androstenedione, DHEA, DHEAS levels can be increased.

3. female steroid estrogens estrone and abnormal, a constant level of estrogen, E2 levels fluctuate a small, non-cyclical changes in the normal menstruation, E1 levels increase, E1/E2> 1.

4.PRL PCOS can be slightly elevated, but high-class hyperprolactinemia PCOS symptoms can occur, should be identified.

5. urinary 17-OHCS and 17-KS 24h urinary 17 - one increases reflect the increase in adrenal androgen secretion.

6. dexamethasone suppression test can inhibit the secretion of adrenal hormones, taking dexamethasone 0.5mg, every 6 hours for 4 days after the service to take blood samples, such as differences in serum DHEA, or dehydroepiandrosterone sulfate in urine 17 - ketone steroids is suppressed to a normal level, can be ruled out adrenal tumors or hyperplasia of the possible.

7. chorionic gonadotropin (HCG) stimulation test HCG can stimulate ovarian androgen synthesis, HCG injection can cause elevated levels of plasma testosterone.

8. corticotropin (ACTH) stimulation test ACTH stimulation test may promote endogenous adrenal androgen DHEA and urinary 17-KS increased.

by HCG stimulation test, dexamethasone suppression test, ACTH stimulation test can help identify the source of elevated androgens.

9. vaginal cytology maturation index is a preliminary understanding of sex hormone status of the easy way, too much testosterone in the smear layer of cells often exist in three types of film, 3 layers of cells increased significantly when the number is almost equal, but must inflammation of the phase difference between the levels of estrogen can be estimated from the percentage of superficial cells, but does not reflect the blood hormone levels.

10. determination of basal body temperature to determine ovulation, ovulation was biphasic type, no ovulation were generally single-phase type.

1. B-ovarian pelvic increase, at least 10 of each plane more than 2 ~ 6mm diameter follicles, mainly in the peripheral ovarian cortex, a few scattered interstitial, interstitial increase.

2. Pneumoperitoneum radiography ovaries increased 2 to 3 times, if the main source of androgen adrenal, the ovary is relatively small.

3. laparoscopic (or surgery) See full ovarian morphology, pale smooth surface, including film thickness, and sometimes it shows under the capillary network, because the color was pearl-like appearance, commonly known as oyster ovary, the surface shows multiple cystic follicles.

4.s high-resolution transvaginal ultrasound ovaries, making the diagnosis of PCOS have a breakthrough, at present, there are experienced doctors do this test has become the basis for diagnostics, transvaginal probe polycystic ovary 100%, The abdominal missed 30% of patients, obese patients for unmarried anal ultrasound can be applied to detect, 1986, Adams was first reported in patients with PCOS is characterized by bilateral ovarian ovarian ultrasound are more than 8 diameter <10mm follicles, arranged along the periphery, accompanied by increased central interstitial region, polycystic ovary is usually enlarged, but there are also normal-sized ovary, PCOS patients with ultrasound can also be normal.

5.CT, MRI can also be used to check ovarian morphology.
