Embryologic outcomes among patients using a microfluidics chip compared to density gradient centrifugation to process sperm: a paired analysis
Journal of assisted reproduction and genetics ·doi:10.1007/s10815-022-02504-1

PURPOSE: To evaluate embryologic outcomes among paired IVF cycles in which a microfluidics chip was utilized compared to density gradient centrifugation for sperm processing. METHODS: This was a retrospective cohort study of 88 paired IVF …

The association of obesity with euploidy rates in women undergoing in vitro fertilization with preimplantation genetic testing
Journal of assisted reproduction and genetics ·doi:10.1007/s10815-022-02624-8

PURPOSE: The purpose of this study was to determine the impact of body mass index (BMI) on euploidy rates for in vitro fertilization (IVF) cycles with preimplantation genetic testing (PGT) utilizing primarily next-generation sequencing (NGS…

Pregnancy outcomes after frozen-thawed single euploid blastocyst transfer following IVF cycles using GNRH agonist or HCG trigger for final oocyte maturation
Journal of assisted reproduction and genetics ·doi:10.1007/s10815-019-01646-z

PURPOSE: To assess whether GnRH agonist trigger impacts the implantation potential of euploid embryos. METHODS: Retrospective cohort study done at an academic IVF center evaluating frozen-thawed embryo transfer (FET) cycles in which single…

Comparison of luteal estradiol patch and gonadotropin-releasing hormone antagonist suppression protocol before gonadotropin stimulation versus microdose gonadotropin-releasing hormone agonist protocol for patients with a history of poor in vitro fertilization outcomes
Fertility and sterility ·doi:10.1016/j.fertnstert.2008.04.024

OBJECTIVE: To compare IVF outcomes in poor-responder patients undergoing stimulation after luteal phase E(2) patch/GnRH antagonist (LPG) protocol versus microdose GnRH agonist protocol. DESIGN: Retrospective analysis. SETTING: University-…

Impact of leuprolide acetate on luteal phase function in women undergoing controlled ovarian hyperstimulation and intrauterine insemination
Fertility and sterility ·doi:10.1016/j.fertnstert.2005.07.1330

OBJECTIVE: To determine if the combination of leuprolide acetate (LA) and human menopausal gonadotropin (hMG) results in luteal phase dysfunction. DESIGN: A prospective, randomized clinical trial. SETTING: A tertiary care university ferti…

The value of increasing the dose of human menopausal gonadotropins in women who initially demonstrate a poor response
Fertility and sterility ·doi:10.1016/s0015-0282(16)56874-5

OBJECTIVE: To evaluate the benefit of increasing the hMG dose in subsequent superovulation cycles for those individuals who demonstrate a poor response on up to three ampules of hMG daily. DESIGN AND SETTING: Retrospective analysis of all …

rct 1993
A randomized and longitudinal study of human menopausal gonadotropin with intrauterine insemination in the treatment of infertility
Obstetrics and gynecology

OBJECTIVE: To study in a randomized and longitudinal manner the efficacy of human menopausal gonadotropin (hMG) superovulation combined with intrauterine insemination (IUI) versus IUI alone in the treatment of various causes of infertility …
