Role of luteinizing hormone in primiparous sow responses to split weaning.
In 45 primiparous sows, we examined endocrine, ovarian and reproductive responses to split-weaning or five injections per day of 800 ng GnRH from 18 to 21 days of lactation. There was no effect of treatment on absolute or changes in sow weight or backfat depth during lactation. Average piglet growth rates were similar among treatments except that piglets suckling split-weaned sows grew faster (...
متن کاملInhibition of cytochrome P-450 C17 enzyme by a GnRH agonist in ovarian follicles from gonadotropin-stimulated rats.
Our objective was to study the direct action of a GnRH-I agonist, leuprolide acetate (LA), on ovarian steroidogenesis in preovulatory follicles obtained from equine chorionic gonadotropin (eCG)-treated rats. Previously, we have demonstrated an inhibitory effect of LA on steroidogenesis and follicular development. In this study, we tested the hypothesis that gonadotropin-releasing hormone (GnRH)...
متن کاملThe adjuvant effect of oxytocin on GnRH analogue buserelin.
The mucosa of the nasal cavity has relatively high premeability for peptides. Because of the digestive peptidase activity of the gut, the nasal pathway is currently the route of choice for nonparenteral administration of many peptides including gonadotropin releasing hormone analogues (GnRH-a) . Nevertheless, the transmucosal route of administration may have some problems. Variations exist from...
متن کاملComparisons of GnRH antagonist versus GnRH agonist protocol in poor ovarian responders undergoing IVF.
BACKGROUND In view of the discrepancies about the GnRH antagonist (GnRH-ant) ovarian stimulation protocols having some potential advantages compared with the GnRH agonist (GnRH-a) protocols in poor ovarian responders IVF/ICSI, a meta-analysis of the published data was performed to compare the efficacy of GnRH-ant versus GnRH-a protocols for ovarian stimulation in IVF poor response patients. M...
متن کاملGnRH agonist versus GnRH antagonist in poor ovarian responders: a meta-analysis.
The aim of this meta-analysis was to compare the efficacy of gonadotrophin antagonist (GnRH-ant) versus GnRH agonist (GnRHa) as coadjuvant therapy for ovarian stimulation in poor ovarian responders in IVF/intracytoplasmic sperm injection cycles. Search strategies included on-line surveys of databases such as MEDLINE , EMBASE and others. A fixed effects model was used for odds ratio (OR) and eff...
