Effects of recombinant LH supplementation to recombinant FSH during induced ovarian stimulation in the GnRH-agonist protocol: a matched case-control study
BACKGROUND Some studies have suggested that the suppression of endogenous LH secretion does not seem to affect the majority of patients who are undergoing assisted reproduction and stimulation with recombinant FSH (r-FSH). Other studies have indicated that a group of normogonadotrophic women down-regulated and stimulated with pure FSH preparations may experience low LH concentrations that compr...
متن کاملSuppression of LH during ovarian stimulation: effects differ in cycles stimulated with purified urinary FSH and recombinant FSH.
There has been much debate about the role of luteinizing hormone (LH) during follicle stimulating hormone (FSH)-treated ovarian stimulation for assisted reproduction, where the endogenous LH is suppressed using a gonadotrophin-releasing hormone analogue. The requirement for LH in oestradiol biosynthesis is established, but other effects of 'insufficiency' are less clear, and little attention ha...
متن کاملPretreatment with oral contraceptive pills to identify poor responders that may benefit from rLH supplementation during GnRH-antagonist treatment for IVF: A pilot perspective study proposal
Controlled ovarian stimulation, using a gonadotrophin-releasing hormone (GnRH) antagonist protocol, is a potential treatment option for women with a low response to other fertility treatments as it appears to be at least as effective as GnRH agonists (long protocol). However, previous studies have indicated that the administration of GnRH antagonist may cause an excessive reduction in endogenou...
متن کاملSupplementation with a recombinant human chorionic gonadotropin microdose leads to similar outcomes in ovarian stimulation with recombinant follicle-stimulating hormone using either a gonadotropin-releasing hormone agonist or antagonist for pituitary suppression.
OBJECTIVE To compare the outcomes of protocols for ovarian stimulation with recombinant hCG microdose, with GnRH agonists and antagonists for pituitary suppression. DESIGN Prospective nonrandomized clinical trial. SETTING A private assisted reproduction center. PATIENT(S) We studied 182 patients undergoing intracytoplasmic sperm injection (ICSI) cycles, allocated into two groups: GnRH ago...
متن کاملIndividualized Treatment from Theory to Practice: The Private Case of Adding LH during GnRH Antagonist-based Stimulation Protocol
UNLABELLED The study evaluated the proportion of patients whose pituitary glands respond with a sharp decrease in luteinizing hormone (LH) levels when exposed to a conventional dose of 0.25 mg gonadotropin releasing hormone (GnRH) antagonist in a prospective, single-center, non-randomized, proof-of-concept study. Fifty women eligible for in vitro fertilization (IVF) received recFSH (Gonal-F) fr...
