Background & aim: There are conflicting results regarding the benefit of gonadotropin releasing hormone (GnRH) agonist treatment on frozen embryo transfer (FET) outcome. No study was found to compare pregnancy outcome between patients undergoing short and long acting types of GnRH agonist for FET cycles. This study aimed to assess the effectiveness of short and long ac...

To investigate the channels and neurotransmitters in the ventrolateral medulla (VLM) oblongata that are responsible for the maintenance of sympathetic tone and cardio-respiratory reflex regulation. Microinjections of excitant amino acid (glutamate, 100 nl, 100 mM), calcium channel blockers, agonists and antagonists were made throughout the VLM in anaesthetized rats. Arterial blood pressure, sym...

Objective The objective of this study is to compare rates of pregnancy and IVF parameters in subjects who were stimulated with follicle stimulating hormone (FSH) plus either recombinant human luteinizing hormone (r-LH) or human menopausal gonadotropins (hMG), in long gonadotropin releasing hormone (GnRH) agonist IVF protocols. MaterialsAndMethods This is a cohort study of patients undergoing IV...

Background GnRH agonist triggering is one of the strategies for ovulation triggering and final maturation of oocytes. So , should be notice for luteal phase support in these cycles. At the first it was began for prevention of severe OHSS but it was associated with luteal phase problem and lower pregnancy rate due to luteolysis effects of GnRH agonists. So, two other alternative strategies have ...
