A romatase enzyme inhibitor versus gonadotropin for induction of ovulation in patients with polycystic ovary syndrome resistant to clomiphene citrate a randomized controlled trial [PDF]

Minia Journal of Medical Research, 2019
Introduction: Clomiphene citrate (CC) is the first drug used to induce ovulation in patients with poly cystic ovary syndrome (PCOS). Although 70–80% of such women ovulate when treated with CC, only 40% become pregnant (van Wely et al., 2005).

Mapping Steroidogenic Perturbations Under Endocrine Disruptor Mixtures Across Demographic Subgroups: Structural and Metabolomic Insights

Advanced Science, EarlyView.
Population‐scale EDC–hormone association mapping among 4255 participants across demographic subgroups identifies phthalate metabolites as the most consistent signals associated with lower testosterone‐related markers in males. Integrative mechanistic validation prioritizes MCPP as a key phthalate metabolite linked to CYP17A1‐centered disruption of ...

SDF‐1 Attenuates Oocyte Quality Decline During Reproductive Aging Through Autophagy‐Enhanced Stress Granule Scavenging

Advanced Science, EarlyView.
SDF‐1 levels decline significantly with maternal aging. Exogenous supplementation restores meiotic spindle morphology, chromosomal alignment, and mitochondrial function while reducing oxidative stress in aged oocytes. Mechanistically, SDF‐1 enhances autophagic activity to clear accumulated stress granules, thereby rescuing fertilization competence and ...

Expanded application to plant reproductive tissues of a branched DNA probe‐based in situ hybridization method

Applications in Plant Sciences, EarlyView.
Abstract Premise Detecting clear tissue‐ and organ‐specific patterns of gene expression is key to understanding the genetic mechanisms that control plant development. In situ hybridization (ISH) of mRNA is one of the most precise, yet most challenging approaches to gene expression assays.

Microarray-based analysis of fish egg quality after natural or controlled ovulation

BMC Genomics, 2007
Background The preservation of fish egg quality after ovulation-control protocols is a major issue for the development of specific biotechnological processes (e.g. nuclear transfer).

Unraveling ovarian histology: The key morphological aspects that spur the development of the Fossa ovarii in equine

The Anatomical Record, EarlyView.
Abstract The equine ovary exhibits unique structural and developmental features that distinguish it from those of other domestic species, including the presence of an ovulation fossa and an inversion of cortical and medullary layers. This study aimed to investigate the morphostructural development of the equine fetal ovary, with particular emphasis on ...

EVALUATION OF LETROZOLE THERAPEUTIC EFFECT IN INFERTILE WOMEN [PDF]

Acta Medica Iranica, 2007
Combination therapy with clomiphene citrate plus gonadotropin (clomiphene citrate plus HMG) in induction ovulation reduce the gonadotropins dose but antiestrogenic effect of c.c. can decrease pregnancy rate.

Association of anti-mullerian hormone and free androgen index level on response to clomiphene citrate in PCOS infertile women

Gynecology and Obstetrics Clinical Medicine, 2022
Background: Polycystic ovary syndrome (PCOS) is the leading cause of anovulatory infertility. Clomiphene citrate, insulin-sensitizing drugs, aromatase inhibitors, gonadotropins, or laparoscopic ovarian drilling are various methods used for ovulation ...

Tracing the evolutionary history of the morpho‐anatomy of baculum in primates

The Anatomical Record, EarlyView.
Abstract Animal morphology reflects both evolutionary history and present‐day adaptation. Male mammal copulatory structures such as the baculum (penile bone) are ideal for studying these processes because of their complexity and high interspecific variability. In primates, however, research has focused mostly on baculum length.

Integrated microanatomy and microstructure of the maxillary tooth plate reveal a reinforced feeding system and tougher diet in Late Triassic Hyperodapedontinae (Rhynchosauria, Archosauromorpha)

The Anatomical Record, EarlyView.
Abstract Hyperodapedontine rhynchosaurs possessed a unique oral apparatus, long interpreted as an adaptation for processing abrasive and resistant plant material. However, the microanatomical and histological evidence supporting this interpretation remains poorly documented.
