The Role of Serum and Seminal Fluid Anti-Müllerian Hormone (AMH) in Differentiating Subtypes of Male Infertility.

مجلة كلية الطب
Background: Infertility is the inability to conceive after one year of unprotected intercourse, with male factors accounting for about 50% of cases. Anti-Müllerian hormone (AMH), a glycoprotein belonging to the Transforming growth factor beta family, is

Sex Determination in Sponges

Molecular Reproduction and Development, Volume 93, Issue 6, June 2026.
ABSTRACT Sex determination in Porifera remains one of the least understood aspects of early metazoan biology despite the group's key phylogenetic position. Sponges display exceptional diversity in sexual systems—ranging from stable gonochorism to sequential hermaphroditism and sex reversal—yet lack morphological dimorphism and any discrete gonadal ...

Anti-Mullerian hormone (AMH): Regulator and marker of ovarian function

, 2010
In this review, the role of anti-Mullerian hormone (AMH) as a regulator and marker of ovarian function is described. Studies in mice showed that AMH is one of the intra-ovarian growth factors regulating primordial follicle recruitment and follicle ...

Predicting live birth following single euploid frozen‐embryo transfer via β‐hCG dynamics: iHOPE prognostic model with external validation

Ultrasound in Obstetrics &Gynecology, Volume 67, Issue 6, Page 824-835, June 2026.
ABSTRACT Objectives To determine the prognostic value of serum β‐human chorionic gonadotropin (β‐hCG) for predicting live birth following single euploid frozen‐embryo transfer (FET), and to develop and validate a prognostic model (iHOPE) for this purpose. Methods This retrospective cohort study used data from two large fertility practices.

Protein Tyrosine Phosphatase 1B‐Mediated Granulosa Cell Insulin Resistance Links Metabolic Stress to Aging‐Relevant Ovarian Dysfunction and Is Reversed by Gengnianchun

Aging Cell, Volume 25, Issue 6, June 2026.
Metabolic stress induces insulin resistance and upregulates PTP1B in granulosa cells, leading to aging‐relevant ovarian dysfunction. Gengnianchun (GNC) suppresses PTP1B, restores IRS1–AKT2–GLUT4 signaling, and preserves follicles, highlighting PTP1B as a therapeutic target for ovarian dysfunction in metabolically vulnerable states.

Elimination Half-Life of Anti-Mullerian Hormone

, 2012
Context: Anti-Mullerian hormone (AMH) is a glycoprotein that is secreted by the granulosa cells in the human ovary. In the postpubertal female, circulating AMH reflects the number of follicles within the ovary.

Fat reduction mediates the efficacy of intensive lifestyle interventions on fertility‐sparing treatment in overweight patients with endometrial cancer and intraepithelial neoplasia

Acta Obstetricia et Gynecologica Scandinavica, Volume 105, Issue 6, Page 1052-1063, June 2026.
Intensive lifestyle interventions‐based weight management targeting fat reduction may enhance fertility‐sparing treatment outcomes in overweight patients with endometrial cancer or its precursor. Our findings advocate the integration of body composition‐guided weight management into standardized protocols.

Anti-Mullerian hormone and polycystic ovary syndrome: assessment of the clinical pregnancy rates in in vitro fertilization patients

, 2013
Objective: The purpose of this study is to investigate the role of serum anti-Mullerian hormone (AMH), follicle-stimulating hormone (FSH) and antral follicle count (AFC) for the prediction of clinical pregnancy rates (CPR) in women with polycystic ovary ...

Anti-Mullerian hormone and risk of invasive serous ovarian cancer

, 2014
Epithelial ovarian cancers either arise directly from Mullerian-type epithelium or acquire Mullerian characteristics in the course of neoplastic transformation.
