or absence of multinucleation (r¼0.047) or the percentage of multinucleated embryos obtained from a single patient (r¼0.088). CONCLUSION: Despite previously documented independent associa- tions of obesity and embryo multinucleation with poor IVF cycle character- istics, obesity did not correlate with the presence of multinucleated human embryos in our dataset. P-664 Wednesday, October 16, 2013 NEONATAL OUTCOMES FOR OBESE WOMEN UNDERGOING IN VITRO FERTILIZATION (IVF). M.-Y. M. Leung, a S.-H. Chang, a L. M. Pollack, c J. S. Rhee, b E. S. Jungheim. b a Public Health Sciences, Department of Surgery, Washington University, St. Louis, MO; b Reproduc- tive Endocrinology and Infertility, Department of Obstetrics and Gynecol- ogy, Washington University, St. Louis, MO; c George Warren Brown School of Social Work, Washington University, St. Louis, MO. OBJECTIVE: Previous work investigating IVF outcomes in obese women focuses largely on clinical pregnancy rates, live birth rates and maternal com- plications, but little data exists regarding neonatal outcomes for obese women using IVF. Therefore, we investigated gestational age and birth weight in children born to obese women after IVF. DESIGN: Retrospective cohort. MATERIALS AND METHODS: Inclusion criteria were women with a singleton delivery after their first IVF cycle in our center between 2001 and 2008. Women using donor oocytes were excluded. Associations between maternal body mass index (BMI), gestational age and birth weight at delivery were investigated after classifying women into one of three BMI groups: normal (less than 25 kg/m2), overweight (25-29 kg/m2), and obese (greater than or equal to 30 kg/m2). T- tests and chi-square analysis were used to determine differences in neonatal outcomes between the normal-weight group and the other groups. RESULTS: 206 women met study criteria. Obese women had a signif- icantly higher fraction of preterm births than normal-weight women (37 vs. 21%, p¼0.01). Overweight women had a larger fraction of large for gestational age (LGA) infants (31 vs. 20%, p¼0.05) when compared to normal-weight women. Overweight women had heavier infants compared to normal-weight women, although this difference was not statistically significant (7.02 vs. 6.74 lbs, p¼0.1). Overall infants born to obese women weighed significantly less when compared to infants born to normal weight women (6.29 vs. 6.74 lbs, p¼0.05), which may be attrib- uted to the significantly higher fraction of preterm births among obese women. CONCLUSION: Our findings provide evidence that higher maternal BMI in IVF patients translates into adverse neonatal outcomes including higher incidence of preterm birth, and for infants born at term an increased risk of LGA. This is concerning as preterm birth and LGA at term are known to adversely impact chronic health conditions and development in children. Supported by: K12HD063086. P-665 Wednesday, October 16, 2013 OVARIAN UTILIZATION OF STORED LIPID DURING INDUCED FOLLICULOGENESIS IN THE PLIN2-NULL MOUSE. S. M. Stephens, a E. S. Bales, b D. J. Orlicky, c A. J. Polotsky, a J. Monks, b J. L. McManaman. b a Obstetrics and Gynecology, University of Colorado, Denver, Aurora, CO; b Basic Reproductive Sciences, University of Colorado School of Medicine, Aurora, CO; c Pathology, University of Col- orado School of Medicine, Aurora, CO. OBJECTIVE: Intracellular lipid droplets (LD) have been identified in the ovary and may serve as reservoirs of cholesterol for sex hormone production during folliculogenesis. Perilipin 2 (Plin2) is a LD-associated protein that moderates the storage and metabolism of lipid within LDs. Our objective was to evaluate the utilization of LDs in the ovary during folliculogenesis in the Plin2-null mouse. DESIGN: Comparative. MATERIALS AND METHODS: C57Bl6 (WT) and Plin2-null mice received 5 IU pregnant mare’s serum (PMS) IP at 23 days of age followed by 5 IU human chorionic gonadotropin (hCG) IP 46-48 h later. Mice were euthanized at 48 h after PMS or 12 h after hCG. Ovaries were frozen, sectioned and slide mounted. BODIPY 493/503 and Hoescht were used to stain LDs and nuclei respectively. Slides were imaged by laser confocal mi- croscope at 630x. LDs were quantified by BODIPY staining normalized to nuclear staining within the granulosa and theca of antral follicles using Slide- book 5.5. The median and interquartile range (IQR) was calculated and compared by Mann-Whitney test (STATA 11.0). p<0.05 was considered sig- nificant. 8-12 follicles/strain were imaged per timepoint. RESULTS: Intracellular LD stores did not differ between WT and Plin2- null mice. WT mice demonstrated a significant decrease in LD in theca cells during folliculogenesis. Plin2-null mice did not show a decrease in LD with stimulation in either granulosa or theca.

CONCLUSION: Theca cells utilize intracellular LD during folliculogen- esis. Plin2-null mice have impaired ability to utilize LD in the ovary. The ef- fects of altered ovarian lipid utilization during folliculogenesis on sex hormone production and fertility warrant further investigation. Supported by: UCD Academic Enrichment Fund. P-666 Wednesday, October 16, 2013 OBESITYAND POLYCYSTIC OVARIAN SYNDROME: IS THERE A LINK BETWEEN DYSFUNCTIONAL SLEEP AND IVF OUTCOMES? R. Flyckt, a S. Ibrahim, b J. Tantibhedhyangkul. a a Repro- ductive Endocrinology and Infertility, Cleveland Clinic, Cleveland, OH; b Neurology, Cleveland Clinic, Cleveland, OH. OBJECTIVE: The area of sleep disorders and infertility is essentially un- explored. However, previous research has established a link between polycy- stic ovarian syndrome (PCOS), a common cause of anovulation and infertility, and obstructive sleep apnea (OSA). The present study aims to assess the relationship between sleep patterns and clinical outcomes with in vitro fertilization. DESIGN: Retrospective cohort study. MATERIALS AND METHODS: Women >21 years old who were seen for infertility visits at our institution between 2009 and 2011 were identified. Patients were contacted by email to complete an online questionnaire assess- ing demographics, sleep patterns, and fertility treatments. Spearman and Pearson correlation coefficients for scores on standardized sleep measures and IVF variables were generated for ordinal and ratio data, respectively. RESULTS: 79 patients completing 131 fresh and 90 frozen IVF cycles participated in the online survey. Most patients were Caucasian (94%). Me- dian age and BMI were 36 [32,40] and 23.49 [22, 27, respectively]. 12 re- spondents (15%) indicated their diagnosis as anovulation or PCOS. Relevant findings are noted in Table 1. There is a positive association be- tween daytime sleepiness and more retrieved oocytes and clinical pregnan- cies which persisted when first cycles were independently analyzed.
