Results The mean age at the start of treatment was 8.11 ± 0.70 years in group 1, 8.98 ± 0.38 years in group 2 and 9.46 ± 0.46 years in group 3, respectively. The mean predicted adult height (PAH) SDS at the start of treatment was -1.29 ± 1.16 in group 1, -1.14 ± 0.88 in group 2 and -1.87 ± 1.09 in group 3, respectively. Rate of growth during treatment with GnRHa combined with GH was higher sign...
Tasmanian Atlantic salmon (S. salar) broodstock can experience temperatures above 20 °C, which impairs reproductive development and inhibits ovulation. The present study investigated the prolonged use of gonadotropin releasing hormone analogue (GnRHa) during vitellogenesis as a means of maintaining endocrine function and promoting egg quality at elevated temperature in maiden and repeat spawnin...
BACKGROUND The objectives of this study were: (i) to evaluate the effects of the levonorgestrel-releasing intrauterine system (LNG-IUS) on both proliferation and apoptosis markers and hormone receptors of the eutopic and ectopic endometrium of women experiencing pain related to endometriosis and (ii) to compare the results with those obtained with GnRH agonist (GnRHa) injections. METHODS Pre-...
PURPOSE This study aimed to investigate the influence of gonadotropin releasing hormone agonist (GnRHa) treatment on the weight and body mass index (BMI) of girls who were diagnosed with idiopathic central precocious puberty (CPP) or early puberty (EP). METHODS Patients who were younger than 8 years of age at diagnosis were classified as CPP and patients aged between 8 and 9 years at diagnosi...
Although it is well recognized that continuous administration of gonadotropin-releasing hormone agonist (GnRHa) induces pituitary desensitization, the precise molecular mechanism of this phenomenon is still unclear. To test the hypothesis that pituitary gonadotroph desensitization is mediated by a change in GnRH receptor (GnRH-R) gene expression, the GnRH-R mRNA concentration was analyzed in im...
The age-related decline in fat-free mass is accelerated in women after menopause. The role of ovarian hormone deficiency in the regulation of fat-free mass, however, has not been clearly defined. To address this question, we examined the effect of ovarian hormone suppression on whole body protein metabolism. Whole body protein breakdown, oxidation, and synthesis were measured using [(13)C]leuci...
In polycystic ovary syndrome (PCOS), increased luteinizing hormone (LH) pulse frequency has been attributed to either the hypothalamic gonadotrophin-releasing hormone (GnRH) pulse generator or ovarian oestrogen feedback. To address this issue, a detailed examination of pulsatile LH secretion was undertaken during recovery from GnRH agonist (GnRHa) suppression. Each of six women with PCOS and si...
Gonadotrophin‑releasing hormone (GnRH) agonists (GnRHa) have been widely used to induce a state of downregulation for in vitro fertilization, and its direct effects on the pituitary are well known. However, the effects of GnRHa on the expression of anti‑mullerian hormone (AMH) by follicles in varying stages in vivo remain to be fully elucidated. In the present study 84 cyclic mice were randomly...
The presence of a direct extra-pituitary action of gonadotropin-releasing hormone (GnRH) via specific receptors in endometrial cancer (EC) has been suggested as an explanation for the therapeutic effect of GnRH analogue (GnRHa) in recurrent disease. We have sought the expression of the GnRH peptide and functional GnRH receptor (GnRH-R) in human tissues and cell lines to investigate the possibil...
BACKGROUND Depot preparations of gonadotropin-releasing hormone agonists (GnRHa) are the gold standard drugs for the treatment of central precocious puberty. A concern about these drugs is obesity. OBJECTIVES This study aimed to investigate the effect of gonadotropin-releasing hormone agonists (GnRHa) therapy on body mass index (BMI) in girls with central precocious puberty (CPP). PATIENTS ...
