Clinical significance of serum MBD3 detection in girls with central precocious puberty

open access: yesOpen Medicine, 2023
Diagnosis of central precocious puberty (CPP) in girls remains a huge challenge. The current study was to measure the serum expression of methyl-DNA bind protein 3 (MBD3) in CPP girls and assess its diagnostic efficacy. To begin with, we enrolled 109 CPP

Peripheral and central mechanisms involved in hormonal control of male and female reproduction [PDF]

open access: yes, 2016
Reproduction involves the integration of hormonal signals acting across multiple systems togenerate a synchronized physiological output. A critical component of reproduction is the luteinizinghormone (LH) surge, which is mediated by estradiol (E2) and ...

Physiological Effects of Gonadotropin-Releasing Hormone Immunocontraception on White-Tailed Deer

open access: yesHuman-Wildlife Interactions, 2017
Before immunocontraceptives can be considered safe to use on wildlife species, potential health risks should be assessed. Gonadotropin-releasing hormone (GnRH) immunocontraceptive has successfully reduced fertility of white-tailed deer (Odocoileus ...

Timing feedback-inhibition of the male reproductive hormone axis [PDF]

open access: yes, 2008
Hormonal methods of male contraception have addressed feedback-inhbition of the cascade of hormones that has evolved to regulate sperm production but high concentrations of testosterone (T) in the blood have not worked satisfactorily.

Efficiency of Two Protocols of Resynchronization of Estrus and Ovulation in High-Producing Dairy Cows at Peak Lactation

open access: yesActa Veterinaria, 2022
The reproductive efficiency of the cows was monitored after two resynchronization protocols: Ovsynch (OVS) and Double Ovsynch (DOS). The research initially included 70 HF cows who entered the first synchronization protocol – Presynch.

Gonadotropin-Releasing Hormone (GnRH) Receptor Structure and GnRH Binding [PDF]

open access: yesFrontiers in Endocrinology, 2017
Gonadotropin-releasing hormone (GnRH) regulates reproduction. The human GnRH receptor lacks a cytoplasmic carboxy-terminal tail but has amino acid sequence motifs characteristic of rhodopsin-like, class A, G protein-coupled receptors (GPCRs). This review will consider how recent descriptions of X-ray crystallographic structures of GPCRs in inactive and
