this study explored the effects of gnrh agonist (gnrha) immunity on expression of fshr mrna in pituitary and fshr protein in uteri, and also confirmed its efficacy on uterine development. 42 prepuberty and non cyclic ewes were assigned to 6 experimental groups (eg) during anestrus season. animals in eg-i, eg-ii and eg-iii were subcutaneously injected with 200, 300 and 400 μg alarelin antigens (...

routinely, a bolus of 5.000-10.000 iu human chorionic gonadotropin (hcg) is usedfor the final follicular maturation and ovulation as a standard method. hcg has thesame effect of luteinizing hormone (lh) with long half-life. it has the longlutheotrophic effect which increases the risk of ovarian hyper stimulation syndrome(ohss). recently, gonadotropin-releasing hormone agonist (gnrh-a) trigger h...

conclusions our study showed that microrelin is as effective as diphereline in reducing psa and testosterone and can be recommended to initiate medical castration in patients with pc. results each group contained 40 patients. in group a, psa was reduced from 75.78 ± 72.43 ng/ml to 1.93 ± 1.40 ng/ml after 6 months and testosterone was reduced from 3.50 ± 1.12 nmol/l to 0.81 ± 0.05 nmol/l. there ...

treatment of central precocious puberty (cpp) is the administration of gnrh analogs. metabolic syndrome comprised metabolic disturbances that confer increased risk of (cvd) diabetes mellitus (dm) and cardiovascular disease. this study is a longitudinal prospective study in pediatric endocrinology clinic. 30 non-obese children with idiopathic cpp were involved. total body weight, height, blood p...

A study was conducted to determine whether treatment with deslorelin, a gonadotropin-releasing hormone (GnRH) analog, produced anestrus in gilts and to test the ability of exogenous gonadotropin treatment with a combination of 400 IU equine chorionic gonadotropin and 200 IU human chorionic gonadotropin to induce estrus in GnRH analog-treated gilts. Twelve days after the third estrus, 11 gilts e...

gonadotropin-releasing hormone (gnrh) has neuromodulatory roles in central and peripheral nervous systems. the purpose of this study is to evaluate the effect of gnrh analog (buserelin) on peripheral nerve regeneration. forty adult male rats were divided into buserelin-treated, normal saline, sham surgery, and castrated + buserelin groups. the left sciatic nerve was crushed by a fine forceps an...

results from 110 subjects with cpp, 46 girls (41.8%) were considered as intervention and 64 (58.2%) as control groups. the mean age at initial visit was 7.46 ± 1.03 years. the bmi standard deviation scores in both groups was not significantly different at sixth and 12th months of treatment compared with baseline (p = 0.257 and p = 0.839, respectively). the prevalence of obesity was not signific...

background: gonadotropin-releasing hormone (gnrh) plays essential roles in embryo implantation, invasion of trophoblastic tissue, and steroid synthesis in the placenta. objective: the aim of this study was to evaluate the effect of gnrh antagonist administration on pregnancy outcomes in early implantation period. materials and methods: in this retrospective study, 94 infertile women undergoing ...
