with their doctor included having a child at diagnosis (adjusted odds ratio (OR), 95% confidence interval (CI): 1.7, 1.3-2.1), being younger at diagnosis versus being aged 30-35 (aged 20-24: 1.5, 1.0-2.1; aged 25-29: 1.1, 0.8-1.4), being African American versus being white (1.2, 0.9-1.6), and not being treated with chemotherapy or radiation (3.1, 2.4-4.1). These ORs and 95% CIs were similar in a model restricted to women treated with chemotherapy or radiation. Among women who discussed fertility, 6% of those with a child and 19% of those without were referred to a specialist. CONCLUSION: Over half of reproductive-age women with cancer do not discuss fertility with a doctor before treatment, and even fewer are referred to a specialist. Some women, especially those aged 20-24, may not be getting the information they need to make informed decisions about fertility preser- vation prior to cancer treatment.

Bolat, b B. Haydardedeoglu, a A. Parlakgumus. c a Obstetrics and Gynecology, Baskent University, Adana, Turkey; b Pathology, Baskent University, Adana, Turkey; c General Surgery, Baskent University, Adana, Turkey. OBJECTIVE: To determine whether GnRH agonist(GnRHa) or antago- nist(GnRHant) administration protects the ovarian follicles from cyclophos- phamide(Cyc) induced damage and whether the processes were mediated by AMH. DESIGN: Experimental study. MATERIALS AND METHODS: The control group had intraperitonea- l(ip) saline injection. The GnRHa group had a single subcutaneous(sc) leu- prolide acetate(LA, 1 mg/kg) 28 days prior to a ip saline. The GnRHant group received a single ip cetrorelix acetate(CA, 0.1 mg/kg) 1 h prior to ip saline. The Cyc group had an ip Cyc(75 mg/kg) at day 28. The GnRHa + Cyc group had sc LA(1 mg/kg) 28 days prior to ip Cyc(75 mg/kg). The GnRHant + Cyc group had an ip CA(0.1 mg/kg) 1 h prior to an ip Cyc(75 mg/kg). After oophorectomy on day 35,primordial follicles(PMFs) were counted and AMH expression was assessed by H score. Kruscal Wallis test, c2 test or Fisher Exact test were used in statistical analysis. p<0.05 was considered statistically significant. RESULTS: The Cyc(p¼0.003) and GnRHant(p¼0.003) groups had fewer PMFs than the control group. GnRHa+Cyc, GnRHant+Cyc and Cyc groups had similar numbers of PMFs. The H score was lower in the GnRHa(p <0.001), GnRHant(p¼0.003), and Cyc(p¼0.002) groups than in controls. H scores of GnRHa+Cyc(p¼0.01) and GnRHant +Cyc(p¼0.002) groups were lower than Cyc group.

Changes in AMH expression suggest that GnRHa, GnRHant, and Cyc may be AMH-dependent. Supported by: This study was Supported by Baskent University research fund. P-71 Tuesday, October 15, 2013 SLEEP DISTUBANCESHIGH IN PATIENTS SEEKING FERTILITY PRESERVATION. M. E. Pavone, a J. Hirshfeld-Cytron, b A. Lawson, a K. Smith, a S. C. Klock. a a Obstetrics and Gynecology, Northwestern Univer- sity, Chicago, IL; b Fertility Centers of Illinois, Orland Park, IL. OBJECTIVE: Sleep has been shown to have a key role in an increasing number of medical diseases, yet the impact of sleep on infertile patients re- mains unknown. This is a pilot study to assess the frequency of disturbed sleep in patients undergoing IVF for infertility compared to fertility preser- vation (FP) patients with a concurrent cancer diagnosis. DESIGN: Prospective, multicenter survey. MATERIALS AND METHODS: 57 IVF and 32 FP patients completed a pre-treatment sleep questionnaire of which 50 IVF and 32 FP patients also completed a post-treatment questionnaire. Demographic and IVF stimulation information were also collected. RESULTS: Pre-treatment, FP patients had a significantly higher sleep disturbance score compared to IVF controls (P<.001). At the time of retrieval we found that compared to pre-treatment scores, IVF patients re- ported significantly higher sleep problems (P¼.003). Sleep problem scores in patients undergoing fertility preservation did not significantly change dur- ing treatment, however they continued to be significantly higher than patients undergoing IVF for infertility. CONCLUSION: FP patients report higher baseline problems with sleep compared to IVF patients. However, in contrast to FP patients, IVF patients reported an increase in sleep problems during treatment. Research is warranted which examines the cause of sleep problems in both FP and IVF patients. This work is on-going to determine the role sleep may have on IVF outcomes and the impact of treatment directed to sleep dysfunction. Supported by: K12HD050121 and U54HD076188 (MEP). P-72 Tuesday, October 15, 2013 CLINICAL USE OF VITRIFIED OOCYTES AMONG AUTOLO- GOUS IN VITRO FERTILIZATION (IVF) PATIENTS: A THREE YEAR REVIEW. J. H. Lim, a,b M. A. Stout, a K. A. Milne, a K. S. Richter, a E. E. Levens, a M. J. Tucker. a,c a Shady Grove Reproductive Science Center, Rockville, MD; b Donor Egg Bank USA, Rockville, MD; c Georgia Reproductive Specialists, Atlanta, GA. OBJECTIVE: Successful cryostorage of vitrified oocytes has introduced a therapeutic option giving young women pursuing higher education, begin- ning a career or facing life-threatening disease the opportunity to preserve their fertility while postponing motherhood. Oocyte cryostorage also avoids most of the ethical issues associated with creating embryos that may never be used. DESIGN: Retrospective review. MATERIALS AND METHODS: Autologous oocyte cryopreservation cy- cles performed by a private IVF center from June 2009 to December 2012 were reviewed. A proven oocyte vitrification protocol (7.5% EG+DMSO, followed by 15% EG+DMSO+sucrose) using commercially available media in conjunction with an ‘open’ vitrification carrier was employed. Warming was performed using stepwise dilutions of sucrose. Surviving oocytes were inseminated by intracytoplasmic sperm injection (ICSI). Average age of women at the time of oocyte collection and vitrification was 34.9 yrs. RESULTS: 542 oocytes from 63 patients were thawed, with 477 (88%) surviving. Following ICSI, 356 oocytes displayed normally fertilization (2PN, 75%). Embryo transfer (ET) was performed in 59 cycles with cancel- lation of 4 cycles due to inadequate embryo development. From 59 ETs (1.9 embryos/ET) there were 33 clinical pregnancies and implantation rates were 56% and 44% respectively. For comparison, among fresh oocyte cycles (<35 yrs) from January 2010 to December 2012 (n¼ 2666) resulting clinical preg- nancy and implantation rates were 56% and 49%. CONCLUSION: This review provides clinical staff and patients with valuable information as to the efficiency of oocyte cryopreservation allow- ing informed decisions to be made. While sample size is limited, clinical pregnancy and implantation rates are comparable to fresh cycles. These results are similar to published reports of donor oocyte banking, and sug- gest that vitrification of autologous oocytes provides similar outcomes and may greatly reduce surplus embryos and ethical issues in some patient populations.

Page 2: Effect of fetal calf serum and bovine serum albumin on in vitro development of bovine preantral follicles during three-dimensional culture

OBJECTIVE: To evaluate the effect of bovine serum albumin (BSA) andfetal calf serum (FCS) on in vitro development of bovine preantral follicles.

DESIGN: Bovine preantral follicles were studied individually duringencapsulated three-dimensional culture.

MATERIALS AND METHODS: Bovine preantral follicles (150 to250 mm in diameter) were mechanically isolated from ovaries obtained inlocal slaughterhouse, encapsulated into alginate (0.25% w/v), and culturedfor 21 days at 20% O2 in TCM199 supplemented with BSA (n ¼ 26) orFCS (n ¼ 27) at concentration of 3mg/mL. Follicle development was evalu-ated on the basis of survival, antral cavity formation, oocyte diameter in-crease and the presence of healthy cumulus-oocyte complexes. Data wereanalyzed using Student’s t-tests.

RESULTS: A greater percentage of viable follicles was observed in BSAthan FCS (39, and 7%, respectively, P< 0.05). The rate of antrum formationwas higher in BSA than in the FCS (19 and 11%, respectively, P< 0.05). Nodifference in oocyte diameter (90 to 110 mm) was detected, however the per-centages of retrieved healthy cumulus-oocyte complexes were higher in BSAthan FCS (38.5, and 18.5%, respectively, P < 0.05).

CONCLUSION: The data present herein suggest that BSA offers a betterprotein source than FCS for the in vitro development of alginate-encapsu-lated bovine preantral follicles.

DIRECT INJECTION OF METHOTREXATE PRESERVESFERTILITY IN PATIENTS WITH ECTOPIC PREGNANCY INLOWER UTERINE SEGMENT. T. Honda, R. Honda,M. Yamaguchi, K. Uchino, T. Ohba, H. Katabuchi. Obstetrics and Gynecol-ogy, Faculty of Life Sciences, Kumamoto University, Kumamoto, Japan.

OBJECTIVE: Ectopic pregnancy in lower uterine segment is rare, causedby a cesarean scar or uterine cervix implantation. Recently, management hasbeen shifted from a surgical approach to a more conservative treatment forthese patients. The objective of this study was to evaluate the fertilityoutcome after direct injection of methotrexate (MTX) to the ectopic preg-nancy in lower uterine segment.

DESIGN: Retrospective analysis.MATERIALS AND METHODS: We performed a retrospective analysis

of pregnancy by collecting records of patients with lower uterine segmentpregnancy (7with cesarean scar pregnancy and 9 with cervical pregnancy)managed at Kumamoto University Hospital, Kumamoto, Japan, betweenApril 2005 and March 2012. All patients were treated with direct injectionof MTX under transvaginal ultrasound guidance promptly after diagnosis.The serum hCG level was followed until it was decreased to the non-pregnantrange with periodic observation by transvaginal ultrasound.

RESULTS: The mean age of the 7 patients with cesarean scar pregnancywas 32.3�4.4 years old (range 25-38 years old), and for the 9 patientswith cervical pregnancy, it was 32.3�3.7 years old (range 26-37 yearsold). In the methotrexate treatment group, no patients had serious postoper-ative hemorrhage to be required hysterectomy or transarterial embolization.In the case of cesarean scar pregnancy, 6 of 7 patients desired subsequentpregnancy. Among them, pregnancy was achieved in 5 patients (7 cycles),1 had a repeated cesarean scar pregnancy, 1 had a miscarriage, and 5 resultedin term delivery. Meanwhile, 6 of 9 patients with cervical pregnancy wishedsubsequent pregnancy; finally, 1 had a miscarriage and 3 resulted in termpregnancy.

CONCLUSION: MTX local injection therapy is an effective manage-ment option for preserving the fertility of women with lower uterine ectopicpregnancy.

FERTILITY & STERILITY�

OBJECTIVE: Few studies have addressed the issue of COH for fertilitypreservation in breast cancer patients. Letrozole is currently required in orderto limit the estrogen levels increase. In France, the use of letrozole in this spe-cific area is not allowed. The aim of this study is to evaluate the benefit/risk ofthe ovarian stimulation without letrozole for oocyte freezing in young breastcancer patients undergoing adjuvant chemotherapy.DESIGN: Prospective observational study.MATERIALS AND METHODS: A total of 45 young breast cancer

patients were prospectively included before adjuvant chemotherapy. The in-clusion criteria for being eligible to COH were: age under 40, complete sur-gery, absence of metastases. Lymph node status, presence of hormonalreceptors, BRCA 1/2 were not exclusion criteria. COH protocol consistedin the association of r-FSH and antagonist with a GnRh agonist triggering.r-FSH starting dose varied from 150 to 450 IU. Patients were then enrolledin a systematic oncologic and reproductive follow-up for 3 consecutive years.RESULTS: 13 patients declined the proposal of fertility preservation and 4

were not eligible because of suspect uptakes during positron emission tomog-raphy. 28 patients underwent COH. Mean age was 30.3 +/-3.4. Mean r-FSHdose was 271 +/- 92 IU. The average number of days of supra-physiologicE2 levels (i-e triggering day - day 6) was 5 +/-1. Peak E2 levels ranged from149 to 5314 pg/ml with a mean of 1793 +/- 1173 pg/ml. An average of 10oocytes+/- 5.6was retrieved. Themeannumber of vitrified oocyteswas respec-tively 7 +/-4.9. Time between surgery and chemotherapy was 46.6 days (18-69). Mean duration of follow-up after the end of chemotherapy was 10 months+/- 11. No recurrences were observed during the study period. There was onecase of moderate OHSS and 3 cycle cancellations for insufficient response.CONCLUSION: To date, no oncologic adverse effects were noted. These

preliminary results have to be confirmed in a larger population through amuch long-term follow-up.

OBJECTIVE: Ovarian stimulation can be time consuming, costly, andemotionally stressful for women who are recently diagnosed with cancer.Our objective was to determine if a simplified approach to Letrozole-FSHprotocol could be developed.DESIGN: Secondary analysis of a prospectively collected database.MATERIALS AND METHODS: Fifty consecutive women diagnosed

with breast cancer stage% 3 with normal ovarian reserve underwent ovarianstimulation with letrozole (5mg/day) starting on cycle day (CD) 2 and rFSH150-450 IU on CD 4. Patients were divided into two groups according towhether there were changes in recombinant FSH dose during the cycle.GnRH antagonist (GnRHa, 250 mg/d) was administered daily when thelead follicle size reached 14-mm in mean diameter and was continued untilthe trigger with a GnRH agonist (Leuprolide acetate, 1 mg).RESULTS: The mean age was 37.6 � 2.8 years with 10.6 � 0.6 days of

ovarian stimulation. AGnRHawas initiated on the 6.6� 0.6 th day of ovarianstimulation. rFSH dose remained constant in 64% of patients. Only in 14.4%of the cycles FSH dose was altered prior to antagonist administration. Themean stimulation length in patients who required a change in the rFSHdose was similar to those with constant dose (11.0 � 1.1 vs. 10.4 � 1.1days, p¼ 0.131). A similar % of patients in the former group had a decreaseor increase in their FSHr doses (45.5% vs. 55.5%) and this change was by%75 units. None experienced moderate/severe OHSS.CONCLUSION: The Letrozole-FSH cycles require no or minimal dose

manipulation, since the risk of OHSS is negligible due to lack of pregnancyattempt and GnRH agonist trigger. Accordingly, we propose the followingpractical stimulation protocol: baseline US and blood work on D-2, repeaton SD 6 to evaluate if dose change is needed and start antagonist, and returnSD 10 for trigger decision.Supported by: NIH R01 HD053112 and R21 HD061259.
