- Delivering embryos following 10 years of cryopreservation, using unpaired freeze/thaw techniques: A case report(2021) MELANTONIO, Priscila; ATTIVO, Jessica; GOMES, Alecsandra P.; BONETTI, Tatiana C. S.; MONTELEONE, Pedro A. A.Although frozen embryo transfer is a widely established route for assisted reproduction, successful frozen embryo transfer using embryos that have undergone long term cryopreservation remains relatively unexplored, and its efficacy remains a matter of some debate. This case report describes two successful frozen embryo transfer conceptions in the same patient, one after 3 months of cryopreservation and the second 10 years after cryopreservation. These embryos were cryopreserved using the slow freezing technique and were thawed using an unpaired technique (ultra-rapid warming) after 10 years of storage.
- The impact of balanced reciprocal translocation - 46,XX,t(7; 17) (p13;q24) probably involving the SOX9 gene in the in vitro fertilization with own oocytes evaluated by preimplantation genetic testing or donated oocytes(2019) PEREGRINO, Pedro F. M.; GOMES, Alecsandra; FUJII, Mariana; BONETTI, Tatiana C. S.; RIBOLDI, Marcia; MONTELEONE, Pedro A. A.Preimplantation genetic testing (PGT) for in vitro fertilization (IVF) - also known as PGT for Structural Rearrangements (PGT-SR) - has emerged as an option for at-risk couples carrying balanced translocations. The female in the couple featured in this case report is a carrier of a balanced reciprocal translocation who underwent IVF. PGT showed all her embryos were aneuploid. She subsequently had two cycles using donor oocytes, which ended in miscarriages.
- Human reproduction: current status(2015) IZZO, Carlos Roberto; MONTELEONE, Pedro Augusto Araujo; SERAFINI, Paulo C.The concern about the maintenance of the human species has existed since the earliest civilizations. Progress in the diagnosis and treatment of infertility has led to the development of assisted reproductive techniques (ART) which, along with the evolution of genetics and molecular biology studies, have contributed in a concrete way to the management of infertile couples. Classic in vitro fertilization was initially developed 35 years ago for the treatment of women with tubal blockage, however, it remains inaccessible to a significant proportion of infertile couples around the world. This can be explained by the lack of specialized clinics in some countries and by the high cost of the procedures. Efforts have been employed to increase the number of treatment cycles for assisted reproduction, as for example, the creation of low-cost programs. Even today, infertility remains a problem of global proportions, affecting millions of couples. The estimate of the incidence of infertility is uncertain, mainly because of the criteria used for its definition. This article aims to review the most important aspects, succinctly, regarding the incidence, etiology, and treatment options available to infertile couples.
