PREDICTIVE FACTORS FOR PREGNANCY AFTER INTRAUTERINE INSEMINATION: A PROSPECTIVE STUDY OF FACTORS AFFECTING OUTCOME

OBJECTIVE: To determine the predictive factors for pregnancy after controlled ovarian hyperstimulation (COH)/intrauterine insemination (IUI). DESIGN: Prospective observational study. SETTING: University-level tertiary care center. PATIENTS AND METHODS: 366 patients undergoing 480 stimulated IUI cycles between November 2007 and December 2008. INTERVENTIONS: Ovarian stimulation with gonadotrophins was initiated and a single IUI was performed 36 h after triggering ovulation. MAIN OUTCOME MEASURES: The primary outcome measures were clinical pregnancy and live birth rates. Predictive factors evaluated were female age, duration of infertility, indication for IUI, number of preovulatory follicles, luteinizing hormone level on day of trigger and postwash total motile fraction (TMF). RESULTS: The overall clinical pregnancy rate and live birth rate were 8.75% and 5.83%, respectively. Among the predictive factors evaluated, the duration of infertility (5.36 vs. 6.71 years, P = 0.032) and the TMF (between 10 and 20 million, P = 0.002) significantly influenced the clinical pregnancy rate. CONCLUSION: Our results indicate that COH/IUI is not an effective option in couples with infertility due to a male factor. Prolonged duration of infertility is also associated with decreased success, and should be considered when planning treatment.

Affordable ART: a different perspective

BACKGROUND Although ≈ 10% of the population is affected by infertility, the treatment option of in-vitro fertilisation (IVF) remains unaffordable for the majority of infertile couples. We have initiated a lowcost programme incorporating an uncommonly used, but recognized, ovarian stimulation protocol, together with certain costlimiting initiatives in an established assisted reproductive technology (ART) set up. METHODS The medical records of women who underwent the lowcost programme were analysed. Clomiphene citrate 50 mg daily was administered from Day 2 of the cycle and continued till the day of hCG trigger, thus preventing the LH surge. Intermittent doses of human menopausal gonadotrophin 150 IU were administered on alternate days from the 5th day onwards. Oocyte retrieval was carried out once at least two follicles of >18 mm were identified. The cycle was monitored by ultrasound only, with embryo transfer being carried out on Day 3. Clinical outcomes were recorded together with an estimation of the direct costs per cycle. Direct cost calculations did not include professional charges or facility costs. RESULTS Of 143 women evaluated, 104 women underwent embryo transfer. The live birth rate and clinical pregnancy rate per embryo transfer were 19 and 22%. The live birth rate per initiated cycle was 14% (20/143). The multiple pregnancy rate was 26% with no case of ovarian hyperstimulation syndrome being recorded. The average direct cost per cycle was US

Comparison of clinical outcomes following vitrified warmed day 5/6 blastocyst transfers using solid surface methodology with fresh blastocyst transfers

725 for an ICSI treatment cycle. CONCLUSIONS Using this protocol, together with several costcutting measures, we achieved an acceptable live birth rate per transfer of 19% at a reasonable cost. This approach could be used by established ART centres to provide treatment to couples who cannot afford conventional ART.

Obstetric outcomes of monochorionic pregnancies conceived following assisted reproductive technology: A retrospective study

OBJECTIVE To report a case of ovarian heterotopic pregnancy after an IVF cycle. DESIGN Case report. SETTING Reproductive medicine unit, Christian Medical College Hospital, Vellore, India. PATIENT(S) A woman with an ovarian heterotopic pregnancy. INTERVENTION(S) Laparoscopic removal of ovarian ectopic pregnancy. MAIN OUTCOME MEASURE(S) Early detection and successful treatment of heterotopic pregnancy. RESULT(S) Successful laparoscopic management of ovarian pregnancy resulting in a single viable ongoing intrauterine pregnancy. CONCLUSION(S) Clinicians need to be aware of such rare and potentially fatal presentations after IVF, because early diagnosis and management in these cases can yield a favorable outcome.

Effectiveness of GnRH antagonist in intrauterine insemination cycles

OBJECTIVES: The literature regarding clinical outcomes following day 5/6 vitrified warmed blastocysts transfer has been conflicting. We decided to evaluate and compare the clinical outcomes following vitrified warmed day 5/6 blastocyst transfer using a solid surface vitrification protocol with fresh blastocyst transfers. SETTINGS: University teaching hospital. STUDY DESIGN: A total of 249 women were retrospectively analyzed: 146 fresh day 5 blastocyst (group 1), 57 day 5 vitrified warmed blastocyst (group 2), and 46 vitrified warmed day 6 blastocyst (group 3) transfer cycles. Vitrification was done using solid surface methodology (non immersion protocol). The main outcomes were implantation rates, clinical pregnancy, and live birth rate per embryo transfer. RESULTS: The baseline clinical characteristics were similar among all three groups. The implantation and clinical pregnancy rates following vitrified warmed day 6 blastocyst transfers (20.9% and 32.6%) were significantly lower as compared to day 5 fresh and vitrified warmed day 5 blastocyst transfers (40.3% and 56.1%, 36.3%, and 52.6%). However, there was no significant difference in the live birth rates across the three groups (group 1: 37.6%, group 2: 40.3%, and group 3: 28.2%). CONCLUSION: No statistically significant difference was observed in live birth rates between fresh day 5 blastocyst transfers and vitrified warmed day 5/6 blastocyst transfers. Vitrification of blastocysts using solid surface methodology is an efficient method of cryopreservation.

Gonadotrophin releasing hormone antagonist in IVF/ICSI.

OBJECTIVES: The overwhelming numbers of twins following assisted reproductive technology (ART) are dichorionic twins, but monochorionic twins account for around 0.9% of post ART pregnancies. The data for post ART-monochorionic pregnancy outcomes are scarce due to the rarity of this condition. Hence, we evaluated the obstetric outcomes of monochorionic and dichorionic pregnancies conceived on ART. SETTINGS: University teaching hospital. STUDY DESIGN: A case–control study of monochorionic diamniotic (MCDA) and dichorionic diamniotic (DCDA) pregnancies conceived following ART treatment. Charts of all women who conceived following ART from 2008 to 2013 were screened. Among them, the monochorionic twins diagnosed in the first trimester were included and their obstetric outcome was followed-up. For comparison, an equal number of dichorionic twin pregnancies from age and body mass index matched mothers was selected. RESULTS: The baseline clinical characteristics were similar between the two groups. MCDA group had a higher miscarriage rate (50%) than the DCDA group (10%), with three seconds trimester miscarriages in the MCDA group. The live birth rates were lower in the MCDA versus DCDA group (40% vs. 90%). Among triplet pregnancies with a monochorionic component, the live birth rate was only 25%. CONCLUSIONS: Monochorionic pregnancies following ART have poorer obstetric outcomes when compared to dichorionic pregnancies. For monochorionic pregnancies following ART, intensive antenatal surveillance at a tertiary level obstetric and neonatal center may help optimize the outcome.

Blastocyst cryopreservation using solid surface vitrification: A preliminary study

OBJECTIVE To evaluate the effectiveness of GnRH antagonists in women undergoing controlled ovarian stimulation and intrauterine insemination cycles (COS/IUI). STUDY DESIGN Randomized controlled trial. Recruited women were randomized into two groups: GnRH antagonist and control group. The primary outcomes were incidence of premature LH surge and clinical pregnancy rates. RESULTS One hundred and forty-one consecutive women were included in the study, with 70 in the antagonist group and 71 in the control arm. The baseline clinical characteristics were similar in both groups. The incidence of premature LH surge and premature luteinization was lower in the antagonist group as compared to the control group (5% vs. 10.3%, P=0.45 and 5% vs. 13.8, P=0.31) but not statistically significant. The clinical pregnancy rates were lower in the antagonist group (2.8% vs. 10%, P=0.12), which was also not statistically significant. CONCLUSION The addition of GnRH antagonist during controlled ovarian stimulation and intrauterine insemination cycles does not lead to improvement in clinical pregnancy rates.

Symptomatic unilateral pleural effusion: A rare presentation of ovarian hyperstimulation syndrome.

Objective : To study the efficacy of gonadotrophin releasing hormone (GnRH) antagonist in In-vitro-fertilization/Intracytoplasmic sperm injection (IVF/ICSI) cycles. Type of Study : Observational study. Setting: Reproductive Medicine Unit, Christian Medical College Hospital, Vellore, Tamil Nadu. Materials and Methods: GnRH antagonists were introduced into our practice in November 2005. Fifty-two women undergoing the antagonist protocol were studied and information gathered regarding patient profile, treatment parameters (total gonadotrophin dosage, duration of treatment, and oocyte yield), and outcomes in terms of embryological parameters (cleavage rates, implantation rates) and clinical pregnancy. These parameters were compared with 121 women undergoing the standard long protocol. The costs between the two groups were also compared. Main Outcome : Clinical pregnancy rate. Results : The clinical pregnancy rate per embryo transfer in the antagonist group was 31.7% which was comparable to the clinical pregnancy rate in women undergoing the standard long protocol (30.63%). The costs between the two groups were comparable. Conclusions : GnRH antagonist protocol was found to be effective and comparable to the standard long protocol regimen. In addition it was simple, convenient, and patient friendly.

Appendix B: Solid Surface Vitrification

OBJECTIVE: The objective was to evaluate the effectiveness of a blastocyst cryopreservation program using solid surface vitrification. SETTING: This study took place in a university teaching hospital. STUDY DESIGN: Retrospective observational study. MATERIALS AND METHODS: Women undergoing frozen embryo transfer cycles over a 4-year period between 2006 and 2010 were studied. The cryopreservation policy followed was a vitrification protocol performed at the blastocyst stage, using a solid surface (nonimmersion) method. The post-thaw survival rate, implantation rate, clinical pregnancy rate, live birth rate, and neonatal outcome were recorded. RESULTS: Eighty-one women underwent 86 frozen embryo transfer cycles. Of the 240 blastocysts warmed, 204 survived giving a cryosurvival rate of 85% (204/240). The clinical pregnancy, implantation, miscarriage, ongoing pregnancy, and live birth rates per transfer were 47%, 29%, 12%, 16%, and 23% respectively. Of the 20 live births, there were 16 singletons and 4 twins. Eleven boys and 13 girls were delivered with no major or minor abnormality detected. CONCLUSION(S): The blastocyst vitrification protocol using the solid surface method is effective with results comparable to fresh blastocyst transfers. While retaining the rapid cooling effect, the nonimmersion technique eliminates the risk of contamination and disease transmission. Larger studies with long-term follow-up data would further confirm the efficacy and safety of this method of vitrification.
