PREDICTORS OF LIVE BIRTH RATE (LBR) AFTER INTRAUTER-INE INSEMINATION (IUI) CYCLES. Z. Khan, E. P. Barnard,D. E. Morbeck, J. R. Jensen. Obstetrics & Gynecology, Mayo Clinic, Ro-chester, MN.

OBJECTIVE: For patients undergoing fertility treatments, LBR is a moreclinically relevant measure of successful outcome than clinical pregnancyrates (CPR). We report prognostic variables related to LBR after IUI cycles.

DESIGN: Retrospective cohort study.MATERIALS AND METHODS: All women undergoing IUI from 1/1/

2005-12/31/2013 at Mayo Clinic, Rochester who gave IRB consent wereincluded in the study. Information regarding ovulation induction (OI) proto-cols and semen parameters was collected. Regressionmodels were utilized toidentify independent factors associated with LBR.

Numbers shown as: Mean�Standard Deviation or Count(Percentage)

RESULTS: A total of 959 women who underwent 2605 IUI cycles wereincluded. Overall 13.6% women had a positive pregnancy test. CPR andLBRswere 12.7% (n¼332) and 9.5% (n¼248).Mean gestation age at deliverywas 39.8�10.2 weeks. Women with successful live birth (LB) were younger;more of them used gonadotropins for OI and had hCG trigger compared towomen without LB. They also used fresh semen sample for IUI and the spermmotility in the ejaculate (SME)aswell as the inseminate (postwash) (SMI)washigher in this group compared towomenwithoutLBs. In thefinalmultivariablemodel maternal ageR38 years, stimulation protocol (oral agents vs. gonado-tropins), SME>40% and SMI>70% were independently associated with LBwith adjusted odds ratios (95%CI) of; 0.43 (0.27-0.67), 0.74(0.06-0.53) vs.1.51 (1.10-2.09), 1.87(1.04-3.69) and 1.92(1.11-3.59) respectively. No LBswere reported inwomenR43years,where totalmotile sperm in the inseminatewas <1 million, SME was <20% or SMI was <30%.

CONCLUSION: Although clinically relevant to patients, IUI success asLBR is rarely reported. This large cohort reports maternal age, mode of stim-ulation for OI and sperm motility as important prognostic markers for LB af-ter IUI cycles.

tential risks of methylation alterations and genomic imprinting. Our objectivewas to compare epigenetic alterations in newborns conceived from infertilepatients who underwent either in vitro fertilization (IVF) or intrauterine in-seminations (IUI) treatments.DESIGN: Laboratory investigation.MATERIALS AND METHODS: Three groups of infertile patients that

underwent either IVF or IUI and delivered a viable infant were randomlychosen, Michigan Neonatal Biobank Bloodspots were obtained and deiden-tified, then placed into the appropriate intervention groups: IUI (N¼17),Fresh IVF embryo transfer(N¼38), and Frozen IVF embryo transfer(N¼38).DNA methylation profiles were obtained using Illumina Infinium HumanMethylation 450 BeadChip system.RESULTS: Genders were identified utilizing Y chromosome probes.

There were differences in methylation in male compared with female new-borns: IUI vs. Fresh (1378 to 2082), IUI vs. Frozen (1986 to 3661) and Freshvs. Frozen (1613 to 2165). A number of genes were present in both the male

and the female comparisons: IUI vs. Fresh (638 genes), IUI vs. Frozen (1252genes) and Fresh vs. Frozen (720 genes). Of these genes, a subset showed thesame pattern of methylation changes (hypo- or hypermethylation ) in bothmale and female comparison groups: IUI vs. Fresh (498 genes), IUI vs.Frozen (1052 genes), and Fresh vs. Frozen (559 genes) . Within these groupsof genes that exhibited similar patterns, 90% were hypermethylated in theIUI vs. IVF and the IUI vs. the IVF Frozen groups, while 81% of the genesin the Fresh IVF vs. Frozen comparison were hypomethylated. Disease asso-ciation analysis, using Genomatix software GEPs, identified both Autism andSchizophrenia may be associated with either hypomethylation or hyperme-thylation changes found in IUI and IVF comparisons.CONCLUSION: Our data is consistent with an alteration of DNA methyl-

ation profiles in babies conceived through IVF treatments compared withIUI. Furthermore the data suggests that embryo freezing may be associatedwith other changes in methylation status. Additional studies are required toascertain the spectrum of effects and pregnancy outcomes on newbornsconceived through ART.Supported by: This work was Supported in part by the WSU Ob/Gyn

OBJECTIVE: Elevated progesterone (P) on day of hCG trigger (P–hCG)has been associated with reduced ART pregnancy rates. However, less isknown about the effect of persistently elevated P days before trigger. The
