Effect of elevating luteinizing hormone action using low doses of human chorionic gonadotropin on double ovulation, follicle dynamics, and circulating follicle-stimulating hormone in lactating dairy cows

Journal of Dairy Science, 2022
: Double ovulation and twin pregnancy are undesirable traits in dairy cattle. Based on previous physiological observations, we tested the hypothesis that increased LH action [low-dose human chorionic gonadotropin (hCG)] before the expected time of ...

Development of a Zebrafish Embryo‐Based Test System for Thyroid Hormone System Disruption: 3Rs in Ecotoxicological Research

Environmental Toxicology and Chemistry, EarlyView.
Abstract There is increasing concern regarding pollutants disrupting the vertebrate thyroid hormone (TH) system, which is crucial for development. Thus, identification of TH system–disrupting chemicals (THSDCs) is an important requirement in the Organisation for Economic Co‐operation and Development (OECD) testing framework.

Follicular expression of follicle stimulating hormone receptor variants in the ewe

Reproductive Biology and Endocrinology, 2013
BackgroundSeveral alternatively-spliced mRNA transcripts of the follicle stimulating hormone receptor (FSHR) have been identified in sheep, including FSHR-1 (G protein-coupled form), FSHR-2 (dominant negative form), and FSHR-3 (growth factor type-1 form).

Prognostic Significance of Solid Subtype of Papillary Thyroid Carcinoma: Analysis of 63 Patients

Head &Neck, EarlyView.
ABSTRACT Objective Solid subtype of papillary thyroid carcinoma (SSPTC) is an uncommon subtype of papillary thyroid cancer (PTC) and its prognostic significance is still controversial. The aim of this review is to present the clinicopathological features of SSPTC and compare its clinical behavior with classical PTC (cPTC).

Effect of Different Culture Systems and 3, 5, 3'-Triiodothyronine/Follicle-Stimulating Hormone on Preantral Follicle Development in Mice

PLoS ONE, 2013
The mechanical method to isolate preantral follicle has been reported for many years. However, the culture systems in vitro are still unstable. The aim of this study was to analyze the effect of the culture system of mice preantral follicles on the ...

The mitochondrial DNA copy number and ovary‐related reproductive disorders: A bidirectional two‐sample Mendelian randomization study

International Journal of Gynecology &Obstetrics, Volume 169, Issue 1, Page 112-120, April 2025.
Abstract Objective In the present study, a bidirectional two‐sample Mendelian randomization approach was utilized to explore potential causal relationships between mitochondrial DNA copy number (mtDNA‐CN) and ovary‐related reproductive disorders (ORRDs), including ovarian dysfunction, ovarian cyst, polycystic ovary syndrome (PCOS), premature ovarian ...

Discrepancies between Antimullerian Hormone and Follicle Stimulating Hormone in Assisted Reproduction

Obstetrics and Gynecology International, 2013
Data from 107 women undergoing their first IVF/ICSI were analyzed. Relationships between antimullerian hormone (AMH) and follicle stimulating hormone (FSH) were analyzed after dividing patients into four groups according to AMH/FSH levels.

Intracellular Follicle-Stimulating Hormone Receptor Trafficking and Signaling

Frontiers in Endocrinology, 2018
Models of G protein-coupled receptor (GPCR) signaling have dramatically altered over the past two decades. Indeed, GPCRs such as the follicle-stimulating hormone receptor (FSHR) have contributed to these new emerging models.
