Gonadotropin-releasing hormone analog (GnRHa) therapy is used in idiopathic central precocious puberty (ICPP) worldwide. It has also been shown that during this therapy, body mass index (BMI) increases slightly as a side effect. We investigated the side effects of GnRHa treatment in ICPP on body composition and insulin resistance (IR). Twenty girls (7.55 +/- 1.02 y) with ICPP were treated with ...

The aquaculture of Senegalese sole (Solea senegalensis) is limited by the failure of cultured breeders (G1 generation) to produce fertilized spawning. Critical reproductive dysfunctions have been observed in both female and male Senegalese sole cultured breeders, including reduced fecundity and diminished sperm production. The present work aimed to study the effectiveness of different hormonal ...

Gonadotropin-releasing hormone ana-logues (GnRHa) are used to treat central precocious puberty. They also are used to delay puberty in short children with a prognosis for impaired adult height. In both cases, growth hormone (GH) treatment is sometimes added. To determine how North American pediatric endocrinologists are using the combination of GH and GnRHa, we searched the National Cooperative...

PURPOSE This study was conducted to analyze the change in the obesity index in girls receiving a gonadotropin-releasing hormone agonist (GnRHa), based on treatment duration, and to aid in nutritional counseling by investigating dietary habits and lifestyle. METHODS Anthropometric examinations were conducted on 62 girls treated with GnRHa from January 2010 through July 2014. Parents were asked...

OBJECTIVES To evaluate the clinical outcomes of gonadotropin-releasing hormone analog (GnRHa) combined with implantation of a levonorgestrel-releasing intrauterine system (LNG-IUS) in adenomyosis patients with significantly enlarged uteruses. SUBJECTS AND METHODS Twenty-one adenomyosis patients whose uterine volumes were greater in size than at 12 weeks' gestation were recruited for the study...

The Senegalese sole (Solea senegalensis) is a flatfish that exhibits severe reproductive dysfunctions in captivity. This study aimed at investigating the existence of a dopamine (DA) inhibitory tone on the reproductive axis of this species. Four groups of Senegalese sole breeders were treated with, saline (controls, CNT), the DA antagonist pimozide (PIM, 5 mg kg(-1)), gonadotropin-releasing hor...

BACKGROUND GnRH agonist (GnRHa) triggering has been shown to significantly reduce the occurrence of ovarian hyperstimulation syndrome (OHSS) compared with hCG triggering; however, initially a poor reproductive outcome was reported after GnRHa triggering, due to an apparently uncorrectable luteal phase deficiency. Therefore, the challenge has been to rescue the luteal phase. Studies now report a...

Chronic gonadotropin-releasing hormone agonist (GnRHa) is used therapeutically to block activity within the reproductive axis through down-regulation of GnRH receptors within the pituitary gland. GnRH receptors are also expressed in non-reproductive tissues, including areas of the brain such as the hippocampus and amygdala. The impact of long-term GnRHa-treatment on hippocampus-dependent cognit...

In stimulated IVF/intracytoplasmic sperm injection cycles, the luteal phase is disrupted, necessitating luteal-phase supplementation. The most plausible reason behind this is the ovarian multifollicular development obtained after ovarian stimulation, resulting in supraphysiological steroid concentrations and consecutive inhibition of LH secretion by the pituitary via negative feedback at the le...
