The age-related required number of zygotes estimated from prior clinical studies of preimplantation genetic testing for aneuploidy (PGT-A).
Women who are undergoing preimplantation genetic testing for aneuploidy (PGT-A) often wish to know how many eggs will be required to optimize the chances of a live birth. However, no precise data on this can yet be provided during genetic counseling for this procedure. On the basis of PGT-A data from related studies and current databases, we have estimated that the number of zygotes required for a 50% chance of a live birth is 8 at age 40 but increases markedly to 21 at age 43. PGT-A markedly reduces the miscarriage rate per embryo transfer but does not alleviate the extremely high number of zygotes required for a live birth in women of an advanced maternal age. Detailed genetic counseling will therefore be desirable prior to undergoing this procedure.
期刊介绍：
Systems Biology in Reproductive Medicine, SBiRM, publishes Research Articles, Communications, Applications Notes that include protocols a Clinical Corner that includes case reports, Review Articles and Hypotheses and Letters to the Editor on human and animal reproduction. The journal will highlight the use of systems approaches including genomic, cellular, proteomic, metabolomic, bioinformatic, molecular, and biochemical, to address fundamental questions in reproductive biology, reproductive medicine, and translational research. The journal publishes research involving human and animal gametes, stem cells, developmental biology and toxicology, and clinical care in reproductive medicine. Specific areas of interest to the journal include: male factor infertility and germ cell biology, reproductive technologies (gamete micro-manipulation and cryopreservation, in vitro fertilization/embryo transfer (IVF/ET) and contraception. Research that is directed towards developing new or enhanced technologies for clinical medicine or scientific research in reproduction is of significant interest to the journal.
