Relationship between maternal age and aneuploidy in in vitro fertilization pregnancy loss.
Objective: To determine the fetal loss rate after documented fetal cardiac activity (7-week sonogram) and to evaluate the chromosomal makeup of these losses in IVF pregnancies.

Mouse ascites Golgi mucin expression abnormalities in natural cycle endometrial biopsies predict subsequent in vitro fertilization-embryo transfer (IVF-ET) failure in patients with previous IVF-ET failures.
Objective: To determine whether endometrial expression of mouse ascites Golgi mucin in a natural, unmedicated cycle predicts subsequent IVF-ET outcome among women with prior IVF-ET failure and poor pre-embryo quality.

A randomized prospective trial comparing gonadotropin-releasing hormone (GnRH) antagonist/recombinant follicle-stimulating hormone (rFSH) versus GnRH-agonist/rFSH in women pretreated with oral contraceptives before in vitro fertilization
Objective: To compare the effects of oral contraceptive (OC) pill pretreatment in recombinant FSH/GnRH-antagonist versus recombinant FSH/GnRH-agonist stimulation in in vitro fertilization (IVF) patients, and to evaluate optimization of retrieval day.

MAG mucin expression abnormalities in natural cycle biopsies predict subsequent IVF failure.
Objective: We have previously shown that MAG mucin expression abnormalities in endometrial biopsies are correlated with reproductive outcome in patients with longstanding infertility and in donor/recipient IVF cycles. In this study we attempted to determine if the expression of MAG in a natural cycle prior to a medicated IVF cycle predicted IVF success.

Single cell RT-PCR detection of IGF-1 and IGF-1 receptor mRNA expression in preimplantation mouse embryo: Correlation with in vitro development
Objective: Recent studies have demonstrated the importance of insulin like growth factors (IGF's) in murine preimplantation development. Supplementation of culture media with IGF-1 increases the rate of blastocyst formation and the inner cell mass cell number. We studied IGF-s gene expression in a single blastomere of an early murine embryo and correlated it with subsequent embryo development in culture.

Seasonality of spontaneous and IVF pregnancy rates and temperature/humidity effect on IVF.
Objective: A seasonal effect on spontaneous pregnancy rates has been observed in the general population. The purpose of this study was to evaluate the fluctuation of pregnancy rates over time in the normal population and in an in vitro fertilization patient population. A secondary goal was to determine if IVF laboratory temperature and humidity were associated with IVF clinical pregnancy rates.

Prospective randomized trial of autologous endometrial coculture versus traditional IVF.
Objective: One factor that may contribute to the poor success rates in IVF may be the suboptimal culture conditions in which fertilization and early embryonic growth occur. This may result in embryos with compromised growth rates and reduced viability. Therefore, in an effort to more closely mimic the in vivo preimplantation environment the culture of embryos on a layer of cells has been developed (coculture). In April 2002, the FDA recommended that nonhuman coculture cell lines not be used in human IVF due to the concern of xenologous viral transmission. Therefore, in an attempt to alleviate these concerns and to improve IVF success rates, our objective was to determine if embryo development and clinical outcome is improved by autologous endometrial coculture (AECC).

Effect of supplementation of leukemia inhibitory factor and epidermal growth factor on murine embryonic development in vitro, implantation and outcome of offspring.
Objective: To evaluate the supplementation of leukemia inhibitory factor (LIF) on epidermal growth factor (EGF) in a single culture system (IVF50) and a sequential culture system (IVF50-S2) to determine whether they had any additional benefit on embryo development and implantation.

Testicular sperm from nonobstructed azoospermic males does not appear to alter preembryo morphology or IVF pregnancy outcome.
Objective: To determine if microsurgical fertilization using sperm obtained from testicular biopsy affects in vitro fertilization/embryo transfer (IVF/ED) preembryo quality and pregnancy outcome.

Glandular Developmental Arrest (GDA): a unifying model of reproductive endometrial pathology.
Objective: We evaluated the possibility that endometrial dating using histologic criteria alone may miss defects in the biochemical differentiation of the endometrial glands that could be critical for optimal endometrial receptivity.
