Objective: Ectopic pregnancy is a well-known complication following in vitro fertilization with embryo transfer; studies have questioned, however, whether there are risk factors that could be identified before the procedure.The objective of this study was to investigate possible involved ectopic fertilization.Methods: Retrospective case-control performed at an assisted reproduction clinic Brazil.To select control group, we used 1:4 ratio.The included 499 patients submitted clinical...

Bilateral ectopic pregnancy is a rare clinical condition with an estimated prevalence of 1/200 000 in spontaneous pregnancies.Studies have found that In Vitro Fertilization (IVF) related to independently, but the incidence tubal disease donor egg recipient population thought be significantly lower than standard IVF population.We report case patient participating egg-sharing program, who was diagnosed ovarian pregnancy, treated surgery.After one week, she contralateral tube.The clinician...

<title>Abstract</title> <bold>Background</bold>: In the past decade, use of donated oocytes has increased, with egg donation (ED) cycles accounting for nearly 10% all assisted reproductive technology (ART) in United States, live birth rates exceeding 50% per cycle. Legal frameworks ED vary across countries; example, Brazil permits voluntary and shared but prohibits commercial donation, leading to imported egg-sharing programs. Despite growing both fresh vitrified oocytes, no studies have yet...

Objective: Recently, it has been discussed whether or not mosaic embryo transfers should be performed since they might result in viable pregnancies, although often end up being discarded.We report a case of successful pregnancy, after transfer from an vitro matured egg and frozen PESA sperm.Case Description: Tests on female aged 40 years male 37 seeking fertility treatment found she had adequate ovarian reserve patent fallopian tubes.He history cryptorchidism inguinal hernia repair.The...

In spontaneous pregnancies, maternal weight and gestational diabetes are independent risk factors for macrosomia large-for-gestational-age newborns. Furthermore, body mass index (BMI) of ≥25 kg/m2 is associated with worse neonatal vitality, classified as an Apgar score < 7 at the fifth minute life. However, few studies have evaluated influence BMI on perinatal outcomes in pregnancies resulting from assisted reproduction. Therefore, this study aimed to analyze whether reproduction influenced...

Atelosteogenesis type II (AO2) and diastrophic dysplasia (DTD) are two recessively inherited, severe skeletal dysplasias caused by mutations in the SLC26A2 gene. AO2 is an invariably lethal condition, while DTD patients may reach adult life, although both diseases have overlapping diagnostic features. Here we report a patient with intermediate phenotype between present successful application of preimplantation genetic diagnosis (PGD) this situation. Sequencing alleles infant identified...

Falência ovariana prematura pode ser idiopática ou estar associada a várias distúrbios auto-imunes genéticos, como as deleções do cromossomo X. Relatamos dois novos casos de braço longo X, em pacientes nuligrávidas apresentando amenorréia secundária e infertilidade. Nenhuma paciente referia história familiar falência relatavam desenvolvimento puberal normal. A avaliação genética mostrou deleção distal no sendo os resultados 46,X,del(Xq22) 46,X,del(Xq13q28), respectivamente. Após o...

With the growing understanding of in vitro fertilization and reproductive technology, magnitude studies related to embryonic evolution has also increased. The optimization embryo selection is crucial minimize risk multiple pregnancies guarantee successful implantation pregnancy. On second day culture, four-cell can be shaped into different arrangements, such as tetrahedral planar. Previous have shown that mammalian embryos a shape any deviation from this ideal configuration negatively affect...
