For women older than age 38, we typically recommend a multiple embryo transfer because older women face a lower success rate with IVF overall. Meanwhile, their likelihood of a multiple birth is also lower. This allows them to transfer a single embryo without increasing their risk of a multiple birth. We can go over in great detail the risks and benefits of the IVF process, considering your medical and financial situation, and help determine the ideal option for you.
Our goal is to give you the information you need to make confident decisions about your fertility treatment options. For more information about IVF, please give us a call at our Bedford office at or our Fort Worth office at You can also schedule an appointment by completing the new patient paperwork , after which a member of our team will contact you to schedule your first consultation.
We look forward to helping you safely achieve your dreams of a family! Single vs. And all too often, fertility doctors are happy to oblige! In , to set standards on how many embryos should be transferred, the American Society for Reproductive Medicine ASRM published revised guidelines regarding the appropriate maximum number of embryos to transfer.
These guidelines suggest a maximum number of embryos to transfer based on the day of transfer Day 3 multi-cell embryos vs. For most patients, these guidelines discourage the use of more than two blastocyst stage embryos in patients under the age of Charts outlining the ASRM guidelines on the number of embryos to transfer can be found below:. Many couples perceive twins as an optimal goal obtained from an IVF cycle.
While such pregnancies can be a good thing when no problems arise, multiple pregnancies even twins increase the obstetric complications. Therefore, the goal of most infertility experts is to obtain singleton pregnancies. To this end, some experts have advocated the transfer of only one embryo at a time for many patients, a practice known as single embryo transfer, or SET.
In general, SET results in a decreased chance of achieving a pregnancy per embryo transfer as compared to the transfer of two or more embryos, but it also greatly decreases pregnancy risks by avoiding multiples. Options: Rates of live birth, clinical pregnancy, and multiple pregnancy or birth by number of embryos transferred are compared. Outcomes: Clinical pregnancy, multiple pregnancy, and live birth rates. Search terms included embryo transfer ET , assisted reproduction, in vitro fertilization IVF , intracytoplasmic sperm injection ICSI , multiple pregnancy, and multiple gestation.
Additional references were identified through hand searches of bibliographies of identified articles. Benefits, harms, and costs: This guideline is intended to minimize the occurrence of multifetal gestation, particularly high-order multiples HOM , while maintaining acceptable overall pregnancy and live birth rates following IVF-ET.
Recommendations: The recommendations made in this guideline were derived mainly from studies of cleavage stage embryos-those cultured for two or three days. Individual IVF-ET programs should evaluate their own data to identify patient-specific, embryo-specific, and cycle-specific determinants of implantation and live birth in order to develop embryo transfer policies that minimize the occurrence of multifetal gestation while maintaining acceptable overall pregnancy and live birth rates III-B.
In general, consideration should be given to the transfer of fewer blastocyst stage embryos than cleavage stage embryos, particularly in women with excellent prognoses and high-quality blastocysts I-A.
