Elevated serum anti-mullerian hormone in adolescent and young adult Chinese patients with polycystic ovary syndrome.
Summary of "Elevated serum anti-mullerian hormone in adolescent and young adult Chinese patients with polycystic ovary syndrome."
To explore the serum anti-mullerian hormone (AMH) level in adolescent and young adult Chinese patients with polycystic ovary syndrome (PCOS), and to evaluate its diagnostic value for PCOS. STUDY
Serum AMH was measured in a cohort of 47 adolescent and young adult Chinese patients with PCOS and 40 age-matched controls. Its diagnostic potential was evaluated by Receiver Operating Characteristic (ROC) curves.
The serum AMH level was higher in PCOS patients than in controls (9.85 +/- 4.93 ng/mL vs. 7.13 +/- 3.02 ng/mL, P = 0.002), and positively related to the mean ovarian volume in PCOS patients (r = 0.319, P = 0.029). The area under the ROC curve for AMH reached a value of 0.664 (0.551-0.778, 95% confidence interval). The best compromise between specificity (70%) and sensitivity (61.7%) was obtained with a cut-off value of 8 ng/mL.
Serum AMH levels are elevated in adolescent and young adult Chinese patients of PCOS. Serum AMH measurement offers a relatively poor diagnostic potency with a sensitivity of 61.7% and a specificity of 70% at 8 ng/mL.

Medical and Biotech [MESH] Definitions
A glycoprotein that causes regression of MULLERIAN DUCTS. It is produced by SERTOLI CELLS of the TESTES. In the absence of this hormone, the Mullerian ducts develop into structures of the female reproductive tract. In males, defects of this hormone result in persistent Mullerian duct, a form of MALE PSEUDOHERMAPHRODITISM.
A pair of ducts near the WOLFFIAN DUCTS in a developing embryo. In the male embryo, they degenerate with the appearance of testicular ANTI-MULLERIAN HORMONE. In the absence of anti-mullerian hormone, mullerian ducts give rise to the female reproductive tract, including the OVIDUCTS; UTERUS; CERVIX; and VAGINA.
The first alpha-globulins to appear in mammalian sera during development of the embryo and the dominant serum proteins in early embryonic life. They reappear in the adult serum during certain pathologic states, primarily hepatocellular carcinoma. They may also be elevated in the amniotic fluid and maternal serum during pregnancy in ANENCEPHALY.
Supporting cells projecting inward from the basement membrane of SEMINIFEROUS TUBULES. They surround and nourish the developing male germ cells and secrete ANDROGEN-BINDING PROTEIN and hormones such as ANTI-MULLERIAN HORMONE. The tight junctions of Sertoli cells with the SPERMATOGONIA and SPERMATOCYTES provide a BLOOD-TESTIS BARRIER.
A live attenuated virus vaccine of duck embryo or human diploid cell tissue culture origin, used for routine immunization of children and for immunization of nonpregnant adolescent and adult females of childbearing age who are unimmunized and do not have serum antibodies to rubella. Children are usually immunized with measles-mumps-rubella combination vaccine. (Dorland, 28th ed)

The aim of this protocol is to study the deleterious impact of adjuvant chemotherapy on ovarian reserve in young women suffering from breast cancer. A new relevant ovarian reserve marker,...
young female cancer patients have improving chances of survival. the main risk is a chronic damage to their ovarian reserve. This may lead to future infertility.
The purpose of this study is to compare the cardiovascular risks of growth hormone deficient young adult males who have completed growth hormone therapy to healthy young adult males.
