) (n).Benefits The pregnancy price was higher within the MEM Seq group than the Seq group (p).However the pregnancy price observed inside the MEM group was similar towards the other individuals .When a logistic regression test was applied it demonstrated that the number of transferred embryos didn’t interfere in the pregnancy rates.Conclusions Our outcomes suggests that supplying different culture circumstances for sibling embryos with subsequent transferCapsule Offering different culture conditions for sibling embryos with subsequent transfer of embryos that were kept in distinct culture media, could raise pregnancy prices in assisted reproduction cycles.S.Geber R.Bossi F.Guimar s M.Valle M.Sampaio OrigenCenter for Reproductive Medicine, Belo Horizonte, Minas Gerais, Brazil S.Geber Health-related College in the Universidade Federal de Minas Gerais, Belo Horizonte, Minas Gerais, Brazil S.Geber Av.Contorno Lourdes, Belo Horizonte, MG CEP , Brazil e-mail [email protected] embryos that had been kept in distinct culture media, may boost pregnancy rates in assisted reproduction cycles.Culture media .Embryo improvement .Pregnancy ratesIntroduction On the list of most significant measures throughout assisted reproduction therapy may be the adequate culture of embryos.Various culture media protocols have already been formulated to this date, which are at present applied in assisted reproduction centers worldwide .The main goal is usually to strengthen embryo development in vitro by mimicking their physiologic environment inside the female reproductive tract, also regarding their biochemical, genetic and epigenetic developmental manage.The initial culture media utilized in IVF cycles have been minimum important media (MEM) and had been basically composed of salts, glucose and phenol red.The media have been then supplemented with pyruvate and albumin .Other components, for instance taurine, EDTA, magnesium, citric acid and alanylglutamine were also added for the medium to be able to boost optimal culture conditions and enhance embryo viability .Later, sequential culture media were formulated and they presented differential composition based on the developmental stage with the embryo and its dynamic metabolic requirements .In these culture media protocols, the first medium composition is based on the levels of carbohydrates present inside the Fallopian tubes; the second medium is primarily based on the levels of carbohydrates present in the uterus, and in addition, it contains crucial and nonessential amino acids, too as vitamins, that improve blastocyst formation and differentiation .In spite of your existing advances inside the formulation of complicated culture media, there is certainly no constant proof that one particular PubMed ID:http://www.ncbi.nlm.nih.gov/pubmed/21318181 protocol is substantially superior to the other folks,J Help Reprod Genet concerning in vitro embryo improvement and pregnancy prices.Additionally, the assumption that 1 precise ingredient could be dangerous to the preimplantation embryo, irrespective of its concentration and interactions in the medium, is still speculative .Distinctive sequential culture protocols have been extensively PRIMA-1 web tested for comparison purposes, to be able to raise the potential to keep in vitro embryo viability by means of the preimplantation period .Nevertheless, it really is uncertain no matter whether embryos would preferably benefit from a single kind of medium in detriment of other individuals and even if effective pregnancy prices would raise when combining unique media composition, as distinct embryos might present unique metabolic demands.Consequently, the objective in the present study is usually to evaluate whet.
