The concentration of circulating anti-Müllerian hormone (AMH) in cattle is a useful endocrine marker for ovarian response to superovulation. Although the AMH concentration undergoes little variation throughout the estrous cycle, its long-term changes remain incompletely understood. Here, we investigated the relationship between superovulation response and plasma AMH concentration in Japanese Bl...
CONTEXT Anti-Müllerian hormone (AMH) is a gonad-specific hormone, which is extensively used as a marker of gonadal status. The level of serum AMH has a high variance in similar individuals for reasons that are unknown. The AMH gene promoter contains a vitamin D response element that may cause vitamin D status to influence serum AMH levels. AIM The objective of the study was to determine wheth...
BACKGROUND Serum anti-Mullerian hormone (AMH) is currently considered the best marker of ovarian reserve and of ovarian responsiveness to gonadotropins in in-vitro fertilization (IVF). AMH assay, however, is not available in all IVF Units and is quite expensive, a reason that limits its use in developing countries. The aim of this study is to assess whether the "ovarian sensitivity index" preci...
BACKGROUND Emerging evidence suggests positive associations between serum anti-Müllerian hormone (AMH), a marker of ovarian function, and breast cancer risk. Body size at young ages may influence AMH levels, but few studies have examined this. Also, no studies have examined the relation of AMH levels with breast density, a strong predictor of breast cancer risk. METHODS We examined associatio...
OBJECTIVES To evaluate preoperative anti-Müllerian hormone (AMH) levels in women with endometrioma or other benign ovarian cysts and differences of AMH changes according to various characteristics. METHODS Ninety-seven patients aged 20 to 39 years who underwent surgery for benign ovarian cyst were enrolled retrospectively. Of these, 65 patients were diagnosed as endometriomas, and 32 had othe...
BACKGROUND In females, anti-Müllerian hormone (AMH) is expressed only by the ovary. AMH is secreted by the granulosa cells of ovarian follicles and appears to regulate early follicle development. AMH is detected in serum from women of reproductive age and its levels vary slightly with the menstrual cycle, reaching the peak value in the late follicular phase. This study investigated serum AMH le...
OBJECTIVE To produce age-related normograms for serum antimüllerian hormone (AMH) level in infertile women without polycystic ovaries (non-PCO). DESIGN Retrospective cohort analysis. SETTING Fifteen academic reproductive centers. PATIENT(S) A total of 3,871 infertile women. INTERVENTION(S) Blood sampling for AMH level. MAIN OUTCOME MEASURE(S) Serum AMH levels and correlation between a...
background: anti-mullerian hormone (amh) levels may represent the ovarian follicular pool and could be a useful marker of ovarian reserve. the clinical application of amh measurement has been proposed in the prediction of quantitative and qualitative aspects in assisted reproductive technologies. objective: this study aimed to assess the relationship between the serum levels of amh and results ...
BACKGROUND AMH levels determined by the conventional AMH assay declined during pregnancy and postpartum. A new Beckman Coulter AMH Gen II assay removes the potentially assay-interfering complement which is activated in pregnancy. The aim of this study was to evaluate if the decline of AMH levels in the serum of pregnant women during the course of pregnancy and peripartum was assay-dependent and...
BACKGROUND To investigate the impact of high circulating AMH on the outcome of CC ovulation induction in women with PCOS. METHODS This prospective cohort observational study included 81 anovulatory women with PCOS who underwent 213 cycles of CC ovarian stimulation. Serum AMH concentrations were measured on cycle day 3 before the commencement of CC in the first cycle, which were compared betwe...
