OBJECTIVES To study the effect of gonadotropin-releasing hormone analogue (GnRHa) on final adult height (FAH) among Jordanian children with central precocious puberty (CPP). Methods: It is a retrospective historical cohort study. We assessed the FAH and height gain in 43 children with CPP (39 females and 4 males) who received GnRHa and 13 children with CPP (11 females and 2 males) who did not r...

PURPOSE Gonadotropin-releasing hormone agonist (GnRHa) is used as a therapeutic agent for central precocious puberty (CPP); however, increased obesity may subsequently occur. This study compared body mass index (BMI) and insulin resistance during the first year of GnRHa treatment for CPP. METHODS Patient group included 83 girls (aged 7.0-8.9 years) with developed breasts and a peak luteinizin...

To evaluate the incidence and characteristics of uterine bleeding during postoperative gonadotropin-releasing hormone agonist (GnRHa) treatment combined with the lowest effective dose of estrogen-progestogen add-back therapy in Chinese women of reproductive age with endometriosis. Seventy Chinese women aged 18 to 50 years with stage III or IV endometriosis and treated with postoperative GnRHa a...

STUDY QUESTION Are there factors predicting the number of total and mature oocytes retrieved after controlled ovarian hyperstimulation (COH) utilizing a gonadotropin-releasing hormone (GnRH) antagonist protocol and a GnRH agonist (GnRHa) to induce oocyte maturation? SUMMARY ANSWER Peak estradiol (E₂) level, post-trigger LH and progesterone and the magnitude of LH rise are independent predicto...

This study tested the hypothesis that testis/reproductive tract abnormalities induced in the rat by neonatal treatment with diethylstilbestrol (DES) result from disturbance of the androgen-estrogen balance. Male rats were treated neonatally with a dose of DES (0.1 micro g) that induced either no or small effects on its own or with a dose (10 micro g) that induced major reproductive tract abnorm...

Central precocious puberty (CPP) develops due to premature activation of the hypothalamic-pituitary-gonadal (HPG) axis, resulting in early pubertal changes and rapid bone maturation. CPP is associated with lower adult height and increased risk for development of psychological problems. Standard treatment of CPP is based on postponement of pubertal development by blockade of the HPG axis with go...

In this study, the benefits of using the first Iranian made GnRHa[D-Ala6 des Gly10] mGnRH ethylamide, to induce spermiation in male rainbow trout, Oncorhynchus mykiss, were evaluated, In addition, its effect on acceleration and synchronization, quality and quantity of milt and the plasma Testosterone (T) fluctuations were examined. For these purposes, 40 non-spermiating male rainbow trouts wer...

AIMS To evaluate if 3 months of gonadotropin-releasing hormone analogue (GnRHa) treatment results in sufficient suppression of pubertal luteinizing hormone (LH) and follicle-stimulating hormone (FSH) profile patterns in short pubertal small for gestational age (SGA) boys. To compare growth hormone (GH) profiles and fasting insulin-like growth factor (IGF)-I and IGF-binding protein-3 (IGFBP-3) l...

Uterine leiomyoma and adenomyosis represent the most common benign tumors of the female reproductive system (Levy, 2008; Parker, 2007; Sankaran & Manyonda, 2008). These tumors are estrogen dependent, develop during the reproductive period, and are suppressed with menopause. Traditional treatments for myomas and adenomyosis have been various types of surgical techniques. Medical management of th...

This meta-analysis was designed to assess the overall performance of GnRHa in preserving the ovarian function in young women undergoing chemotherapy. Electronic literature databases including Pubmed, MEDLINE, Cochrane library, Embase, CNKI and Wanfang were searched for articles published till November, 2013. The articles written in both Chinese and English were considered. Only randomized contr...
