AIM Evaluation of CCCT results and anti-Müllerian hormone (AMH) plasma levels in women with menstrual cycle irregularities and/or infertility. PATIENTS AND METHODS 70 patients with menstrual cycle disturbances were recruited to the study. Clomiphene citrate challenge test (CCCT) was carried out in each patient enrolled. At day 3 of the cycle plasma basic levels of FSH, estradiol, progesterone...

Anti-müllerian hormone (AmH) or müllerian inhibiting substance (mIS), is a dimeric protein part of the transforming growth factor (TGF)-beta subfamily. It plays two important roles in follicle genesis. First, it delays entrance of primordial follicle into pool of follicles in growth and secondly, it decreases the sensitivity of ovarian follicle toward follicle-stimulating hormone (FSH). The ova...

OBJECTIVE This study aimed to identify factors that affect in vitro fertilization (IVF) outcomes in women with diminished ovarian reserve (DOR). METHODS We reviewed 99 IVF cycles in 52 women with DOR between September 2010 and January 2015. DOR was defined as serum anti-Müllerian hormone level of <1.1 ng/dL or serum follicle-stimulating hormone level of ≥20 mIU/mL. Total 96 cycles in 50 patie...

Objective: The treatment strategy for ovarian tumors is often uncertain when a patient wishes to have children. Especially in the case of endometriotic cysts, although pre-assisted reproductive technology cystectomy does not improve live birth rate, surgery may be selected considering symptom and infertility course. In such cases, it necessary pay attention selecting hemostatic method reserve. ...

Mammalian sex determination involves complex interacting networks of cellular and hormonal signals leading to the development of male or female phenotypes. Three main sequential processes are involved: first, the establishment of chromosomal sex at fecundation (genetic sex); second, the development of the undifferentiated gonad into either testes or ovaries (gonadal sex); and third, differentia...

Anti-Müllerian hormone (AMH), also known as Müllerian inhibiting substance, is a member of the transforming growth factor beta superfamily of growth and differentiation factors. In contrast to other members of the family, which exert a broad range of functions in multiple tissues, the principal function of AMH is to induce regression of the Müllerian ducts during male sex differentiation. Howev...

Anti-Müllerian hormone (AMH) has been observed to decrease with the development of hemorrhagic anovulatory follicles (HAFs) in mares. Two studies were conducted to evaluate AMH concentration in mares with HAFs compared to seasonally anoestrous and cyclic mares, and to elucidate changes of AMH with the development of luteinised unruptured follicles (LUFs). In study 1, AMH and progesterone were e...

Patients and Methods: 20 patients aged 18 to 40 years with idiopathic POF were included in a case series study. Measurement of serum concentrations of Follicle Stimulating Hormone (FSH), Luteinizing Hormone (LH), 17β-estradiol (E2) and Anti-Müllerian hormone (AMH) with calculation of Antral Follicles Count (AFC) and volume of ovaries was done before and after bee stings that were administered f...
