The aim of this study was to investigate incompetence for oestradiol-induced LH surges in long-term ovariectomized gilts and male pigs. Gilts (250 days old; n = 36), which had been ovariectomized 30 (OVX 30) or 100 days (OVX 100) before the start of treatment, were challenged i.m. with oestradiol benzoate and were either given no further treatment, fed methallibure to inhibit endogenous GnRH re...

UNLABELLED Pituitary apoplexy represents an uncommon endocrine emergency with potentially life-threatening consequences. Drug-induced pituitary apoplexy is a rare but important consideration when evaluating patients with this presentation. We describe an unusual case of a patient with a known pituitary macroadenoma presenting with acute-onset third nerve palsy and headache secondary to tumour e...

OBJECTIVE To assess whether an early GnRH antagonist start leads to better follicular synchronization and an improved clinical pregnancy rate (CPR). METHODS A retrospective cohort study. A total of 218 infertile women who underwent IVF between January 2011 and February 2013. The initial cohort (Cohort I) that underwent IVF between January 2011 and March 2012 included a total of 68 attempted I...

OBJECTIVES To compare the live birth rates and moderate/severe ovarian hyperstimulation syndrome (OHSS) rates of 2 different approaches using gonadotropin-releasing hormone (GnRH) agonist triggering in high responder women. Methods: A retrospective cohort study was performed to evaluate intracytoplasmic sperm injection (ICSI) and embryo transfer (ET) outcomes in high responder women who underwe...

objective:  to investigate the reproductive outcome of artificial endometrial preparation with exogenous steroids for frozen-thawed embryo transfer with and without pre-treatment with depot gonadotropin releasing hormone agonist (gnrh-a) in women with regular menses. amaterials and methods: this is a prospective randomized clinical trial conducted in two rt centers on 176 women undergoing froze...

OBJECTIVE We compared the assisted reproductive technology (ART) outcomes among infertile women with polycystic ovary syndrome (PCOS) treated with IVM, conventional IVF, GnRH agonist, and GnRH antagonist cycles. METHODS The prospective study included a total of 67 cycles in 61 infertile women with PCOS. The women with PCOS were randomized into three IVF protocols: IVM/IVF with FSH and hCG pri...

Abstract Background Administration of gonadotropin-releasing hormone agonist (GnRH-a) in the luteal phase is commonly used for pituitary suppression during vitro fertilisation (IVF). There an ineluctable risk inadvertent exposure spontaneous pregnancy to GnRH-a. However, little known about complications and repregnancy outcomes affected women neurodevelopmental GnRH-a-exposed children. Methods ...
