Multifetal Pregnancy Reduction

Background: In-vitro fertilization (IVF) is associated with increased multiple pregnancy and its attendant complications. This study evaluates the attitude and acceptance of single embryo transfer (SET) and multifetal pregnancy reduction (MFPR) by clients assessing assisted reproduction in this region.Methods: A cross sectional survey of patients selected for IVF was conducted. Information on demography, knowledge of IVF procedure and their perception, attitude and acceptability of multiple pregnancy as well as their knowledge, attitude and perception to single embryo transfer and multifetal pregnancy reduction were extracted for statistical analysis.Results: Seventy-three women participated in the study. The mean age was 39 years and mean duration of infertility was 8.6 years. Only 3 (4.1%) respondents agreed to have SET as the overwhelming majority (70) 95.9% preferred 2 or more and they felt the more number of embryo transferred the better the chances of achieving pregnancy. Similarly most respondents, 38.4% (28) did not accept MFPR. Most respondents considered age (63%) and duration of infertility (78.1%) as major influencing factor for rejecting SET. Over 75% of respondents said they will still accept multiple embryos transferred despite knowledge of the possible complications.Conclusions: While most infertile women in our sub region appear to recognize the risks with multiple pregnancy, they are less interested in SET or MFPR because they perceive more embryos transferred as a means to maximize treatment outcome. Government funding, client education and a blastocyst transfer protocol may improve acceptability as well as overall preference for less number of embryos transferred in our environment.

Abstract Background Total fertilization failure represents a particularly frustrating condition for couples undergoing in vitro fertilization. With the aim of reducing the occurrence of total fertilization failure, intracytoplasmic sperm injection (ICSI) has become the first choice over conventional in vitro fertilization (IVF) procedures although evidence of improved results is still debated and its use in couples without male factor infertility is not recommended. Among the strategies potentially useful to promote the use of conventional IVF, we herein call attention to the late rescue ICSI, which consists in performing ICSI after 18–24 h from conventional insemination on oocytes that show no signs of fertilization. This treatment has however been reported to be associated with a low success rate until recent observations that embryos derived from late rescue ICSI may be transferred after cryopreservation in a frozen-thawed cycle with improved results. The aim of the present study was to assess whether frozen embryos deriving from rescue ICSI performed about 24 h after conventional IVF may represent a valuable option for couples experiencing fertilization failure. Methods A systematic review on the efficacy of late rescue ICSI was performed consulting PUBMED and EMBASE. Results Including twenty-two original studies, we showed that clinical pregnancy rate per embryo transfer and implantation rate obtainable with fresh embryo transfers after rescue ICSI are not satisfactory being equal to 10 and 5%, respectively. The transfer of cryopreserved rescue ICSI embryos seems to offer a substantial improvement of success rates, with pregnancy rate per embryo transfer and implantation rate equal to 36 and 18%, respectively. Coupling rescue ICSI with frozen embryo transfer may ameliorate the clinical pregnancy rate for embryo transfer with an Odds Ratio = 4.7 (95% CI:2.6–8.6). Conclusion Results of the present review support the idea that r-ICSI coupled with frozen embryo transfer may overcome most of the technical and biological issues associated with fresh transfer after late r-ICSI, thus possibly representing an efficient procedure for couples experiencing fertilization failure following conventional IVF cycles.
