El bienestar del menor por nacer: ¿un interés a ponderar en el acceso a las técnicas de reproducción asistida?
2020
La necesidad de aproximar las legislaciones de los distintos Estados europeos en el ámbito de la reproducción asistida, para evitar el llamado “turismo reproductivo”; así como la conveniencia de realizar una valoración previa de las personas que solicitan ser receptoras de estas técnicas con fines reproductivos, en orden a acercar las distintas formas de filiación, hace que nos planteemos en el presente trabajo la introducción del “bienestar del menor por nacer” como un “interés” más a ponderar para acceder a las técnicas de reproducción asistida. The need to approximate the legislation of the different European States in the field of assisted reproduction, in order to prevent the so-called…
Diagnostic genetic screening for assisted reproductive technologies patients with macrozoospermia
2017
International audience; Macrozoospermia is characterized by a high proportion of abnormal spermatozoa with enlarged heads. So far, it has been associated with mutations only in the Aurora Kinase C gene (AURKC) in some cases. Although many publications have reported failure to conceive in couples with macrozoospermia, a few others have described successful pregnancies, thus raising questions as to whether ICSI and AURKC genetic screening should be recommended in all patients with macrozoospermia. First, we report on two monozygotic twins presenting macrozoospermia for whom the genetic status was explored (Aurora Kinase C sequencing) and whole semen and gradient-selected spermatozoa were anal…
The placenta: phenotypic and epigenetic modifications induced by Assisted Reproductive Technologies throughout pregnancy
2015
International audience; Today, there is growing interest in the potential epigenetic risk related to assisted reproductive technologies (ART). Much evidence in the literature supports the hypothesis that adverse pregnancy outcomes linked to ART are associated with abnormal trophoblastic invasion. The aim of this review is to investigate the relationship between epigenetic dysregulation caused by ART and subsequent placental response. The dialogue between the endometrium and the embryo is a crucial step to achieve successful trophoblastic invasion, thus ensuring a non-complicated pregnancy and healthy offspring. However, as described in this review, ART could impair both actors involved in t…
The Endometrial Microbiome and Its Impact on Human Conception
2021
Changes in the female genital tract microbiome are consistently correlated to gynecological and obstetrical pathologies, and tract dysbiosis can impact reproductive outcomes during fertility treatment. Nonetheless, a consensus regarding the physiological microbiome core inside the uterine cavity has not been reached due to a myriad of study limitations, such as sample size and experimental design variations, and the influence of endometrial bacterial communities on human reproduction remains debated. Understanding the healthy endometrial microbiota and how changes in its composition affect fertility would potentially allow personalized treatment through microbiome management during assisted…
