RESUMO
The incidence of ectopic pregnancy after IVF is increased approximately 2.5-5-fold compared with natural conceptions; however, the aetiology for this increased risk remains unclear. One proposed practice change to decrease the incidence of ectopic pregnancy is blastocyst embryo transfer on day 5 rather than cleavage-stage embryo transfer on day 3. A retrospective cohort study was conducted to compare the risk of ectopic pregnancy following fresh day-5 embryo transfer with day-3 embryo transfer among women who underwent IVF and achieved pregnancy from 1998 to 2011. There were 13,654 eligible pregnancies; 277 were ectopic. The incidence of ectopic pregnancy was 2.1% among day-3 pregnancies and 1.6% among day-5 pregnancies. The adjusted risk ratio for ectopic pregnancy from day-5 compared with day-3 transfer was 0.71 (95% confidence interval 0.46-1.10). Although this analysis included 13,654 cycles, with a two-sided significance level of 0.05, it had only 21.9% power to detect a difference between the low incidence of ectopic pregnancy among both day-3 and day-5 transfers. In conclusion, this study was not able to demonstrate a difference in the risk of ectopic pregnancy among day-3 compared with day-5 transfers.

Objective: To describe the initiation, integration, and costs of reduced-cost infertility services within the maternal health department of a public hospital in a low-income country. Design: Retrospective review of the clinical and laboratory components of patients undergoing in vitro fertilization (IVF) treatment in Rwanda from 2018 to 2020. Setting: Academic tertiary referral hospital in Rwanda. Patients: Patients seeking infertility services beyond the primary gynecological options. Interventions: The national government furnished facilities and personnel, and the Rwanda Infertility Initiative, an international nongovernmental organization, provided training, equipment, and materials. The incidence of retrieval, fertilization, embryo cleavage, transfer, and conception (observed until ultrasound verification of intrauterine pregnancy with fetal heartbeat) were analyzed. Cost calculations used the government-issued tariff specifying insurers' payments and patients' copayments with projected delivery rates using early literature. Main Outcome Measures: Assessment of functional clinical and laboratory infertility services and costs. Results: A total of 207 IVF cycles were initiated, 60 of which led to transfer of ≥1 high-grade embryo and 5 to ongoing pregnancies. The projected average cost per cycle was 1,521 USD. Using optimistic and conservative assumptions, the estimated costs per delivery for women <35 years were 4,540 and 5,156 USD, respectively. Conclusions: Reduced-cost infertility services were initiated and integrated within a maternal health department of a public hospital in a low-income country. This integration required commitment, collaboration, leadership, and a universal health financing system. Low-income countries, such as Rwanda, might consider infertility treatment and IVF for younger patients as part of an equitable and affordable health care benefit.
RESUMO
This report describes an unusual case of ovarian torsion during an IVF cycle prior to vaginal oocyte retrieval and the subsequent embryo development. A 27-year-old, whose husband carries a balanced translocation, presented on stimulation day 11 (day after human chorionic gonadotrophin administration) with signs of right ovarian torsion. Transvaginal ultrasound identified decreased right ovarian venous flow but preservation of right ovarian arterial flow. She underwent emergency laparoscopic right ovarian detorsion followed by vaginal oocyte retrieval on postoperative day 1. Ten oocytes were retrieved from the right detorted ovary, 4/10 (40%) were fertilized and 3/4 (75%) became blastocysts. Fifteen oocytes were retrieved from the left ovary, 14/15 (93%) were fertilized and 9/14 (64%) became blastocysts. All 18 embryos biopsied for preimplantation genetic diagnosis carried unbalanced translocations and none were transferred. The markedly reduced fertilization rate of the oocytes from the previously torted ovary is similar to the rate described in a prior report and likely related to decreased but maintained ovarian arterial flow. This report is unique because not only was the patient's ovarian torsion surgically corrected prior to oocyte retrieval but also the embryos originating from the previously torted ovary had excellent development with 75% progressing to the blastocyst stage.

DESIGN: This study surveyed patients with stored frozen embryos and developed and tested an intervention through a randomized trial to support subjects to consider embryo disposition options (EDOs), especially donation for family building. METHODS: Based on a review of literature on EDOs, the authors developed and mailed a 2-page anonymous survey to 1,053 patients in Massachusetts (USA) to elicit their feelings about their stored embryos. Target patients had embryos cryopreserved for ≥1 year and had not indicated an EDO. Survey respondents were next randomized between usual care (control arm) or an offer of complimentary counseling and educational support regarding EDOs. These counseling sessions were conducted by a licensed mental health professional specializing in infertility treatment. RESULTS: Despite telephone reminders, only 21.3% of patients responded, likely reflecting most patients' reluctance to address EDOs. Respondents endorsed an average of 2 of the 5 EDOs, with the following percentages supporting each option: store for future attempts (82%), continue storage (79%), donate to research (29%), discard (14%), and donate for family building (13%). When asked their opinions towards embryo donation to another couple, 78% of patients agreed that donation is a way to help another couple, 48% would consider embryo donation to another family if they had a better understanding of the process, and 38% would be willing to consider donation if they were not going to use the embryos themselves, but 73% expressed discomfort with donation. In the randomized trial, 7.8% of intervention subjects (n = 8) obtained counseling sessions compared to 0.0% (none) of usual care subjects (p = 0.0069). Counseling participants valued not only discussing EDOs, but also assistance in expressing their feelings and differences with their partners. CONCLUSION: Improvement in counseling rates over the control arm suggests that free professional counseling is a small, but likely effective, step towards deciding on an EDO. ClinicalTrials.gov Identifier: NCT01883934 (Frozen embryo donation study).

OBJECTIVE: To confirm that hCG levels in follicular fluid and serum would be comparable between i.m. and s.c. administration of purified hCG. DESIGN: In a prospective study, serum and follicular fluid levels of hCG after an i.m. or s.c. injection of 10,000 IU of hCG were evaluated 36 hours after injection, that is, at the time of oocyte retrieval. SETTING: This study was carried out in a university-affiliated IVF program. PATIENT(S): Forty women undergoing oocyte retrieval were entered into the study at the time of egg retrieval, that is, 36 hours after hCG administration. INTERVENTION(S): S.c. or i.m. injection of hCG. MAIN OUTCOME MEASURE(S): Serum and follicular fluid concentrations of hCG were evaluated 36 hours after injection at the time of oocyte retrieval. RESULT(S): There was a significantly higher serum hCG level in the s.c. group (348.6 +/- 98 IU/L) vs. the i.m. group (259.0 +/- 115 IU/L) and a significantly higher follicular fluid hCG level in the s.c. vs. the i.m. group (233.5 +/- 85 vs. 143.4 +/- 134 IU/L). CONCLUSION(S): After purified hCG administration via the s.c. route, both serum and follicular fluid levels are greater compared with the i.m. route.

OBJECTIVE: To evaluate whether lifetime future net tax revenues from an in vitro fertilization (IVF)-conceived child are substantial enough to warrant public subsidy relative to the mean IVF treatment costs required to obtain 1 live birth. STUDY DESIGN: Mathematical generational accounting model. METHODS: The model estimates direct financial interactions between the IVF-conceived child and the government during the child's projected lifetime. In the model, we accrue IVF costs required to conceive the child to the government, and then we estimate future net tax revenue to the federal and state governments from this individual, offset by direct financial transfers from the government (eg, child allowances, education, Medicare, and Social Security). We discount lifetime costs and gross tax payments at Treasury Department rates to establish the present value of investing in IVF. We applied US Congressional Budget Office projected changes in tax rates over the course of the model. RESULTS: An IVF-conceived child, average in every respect (eg, future earnings, healthcare consumption, and life expectancy), represents a net positive return to the government. Based on an average employed individual born in 2005, the projected net lifetime tax contribution is US $606,200. Taking into consideration IVF costs and all direct financial interactions, the net present value is US $155,870. CONCLUSIONS: Lifetime net taxes paid from a child relative to the child's initial IVF investment represent a 700% net return to the government in discounted US dollars from fully employed individuals. This suggests that removing barriers to IVF would have positive tax benefits for the government, notwithstanding its beneficial effect on overall economic growth.
