Health outcomes of children born after IVF/ICSI: a review of current expert opinion and literature
2014
The Sixth Evian Annual Reproduction (EVAR) Workshop Group Meeting was held to evaluate the impact of IVF/intracytoplasmic sperm injection on the health of assisted-conception children. Epidemiologists, reproductive endocrinologists, embryologists and geneticists presented data from published literature and ongoing research on the incidence of genetic and epigenetic abnormalities and congenital malformations in assisted-conception versus naturally conceived children to reach a consensus on the reasons for potential differences in outcomes between these two groups. IVF-conceived children have lower birthweights and higher peripheral fat, blood pressure and fasting glucose concentrations than …
Failures (with some successes) of assisted reproduction and gamete donation programs
2013
Although the possibilities for the treatment of infertility have been improved tremendously, not every couple will be treated successfully.Crude overall pregnancy rates of 50-65% per patient can be achieved nowadays, irrespective of the type of profertility treatment applied first.IVF only accounts for about 20% of the pregnancies achieved. Dropout is an important reason for not reaching the estimated pregnancy rate. Even after failed IVF, spontaneous pregnancies do occur. Sperm and oocyte donation (OD) offer additional chances to subfertile couples. Severity of the male factor (in sperm donation) and young donor age (in OD) are important determinants of success.Analysis of assisted reprodu…

Psychological variables in medically assisted reproduction: a systematic review
2022
Introduction: The paths of medically assisted reproduction represent the most important scientific progress to cope with the inability to achieve spontaneous conception (SC) and to reach desired parenthood. Couples undergoing assisted reproductive technology (ART) and couples not facing ovulation induction and artificial fertilization show sufficient levels of well-being and psychological adjustment. However, in some cases couples undergoing ART show lower perceived quality of life than couples with SC. Our aim is to investigate the main psychological variables involved in the special risk condition of medically assisted reproduction and how they could direct specific guidelines to enhance …
La prestación de maternidad en los supuestos de gestación subrogada
2018
Surrogate pregnancy, as a technique of assisted reproduction prohibited by Spanish law, raises a number of legal questions than, in certain cases, trascend of the Civil Law.

Concentration of glutathione and expression of glutathione peroxidases 1 and 4 in fresh sperm provide a forecast of the outcome of cryopreservation o…

Oxidative stress imbalance potentially leads to damage of the structure of the cell and macromolecules such as plasma membrane components, proteins, and DNA. The plasma membrane of the sperm cell, which has high levels of polyunsaturated fatty acids, renders it particularly sensitive to free radical–mediated attacks. The freezing and subsequent thawing of sperm is a physically stressful process carried out during routine procedures in assisted reproduction techniques, which results in a highly variable and unpredictable reduction in the number of motile sperm cells. Subsequently, oxidative status can positively or negatively affect the motility, viability, and fertilizing capacity of thawed…
Impact of Endocrine Disorders on IVF Outcomes: Results from a Large, Single-Centre, Prospective Study
2022
Abstract Endocrine disorders negatively influence the ovarian function, and increasing incidence of endocrine diseases with age may have further negative effects on pregnancy rate. Prospective cohort study of 231 consecutively enrolled patients underwent IVF treatment. In patients with known endocrine disorders, the laboratory parameters were corrected before IVF treatment. One hundred sixty one patients (69.7%) had at least one known and treated endocrine disorder (study group), and 70 patients were endocrine negative (control group). Endocrine disorders diagnosed were thyroid disorders (32.5%), diminished ovarian reserve (23.8%), insulin resistance (22.5%), PCOS (15.2%), hyperprolactinaem…
L'homosexualité et la constitution de la famille : situations française et européenne
2016
The 2013-404 law of 17 May 2013 which opened up the possibility for people of the same gender to get married shows a turning point for the family rights in France. This law, sometimes described as a real tsunami, is the outcome of taking into account the homosexuals' claim for starting a family. Before 2013 the French right did not allow a homosexual couple to be a homoparental family. It did not authorize people of the same gender to get married. Moreover Assisted Reproduction is only reserved to heterosexual couples and Gestation for Others is strictly forbidden in France. This seemingly constrained consensus on the non-legal recognition of the homosexual family is reinforced by the Europ…
Adopción en casos especiales y unidad del status filiationis en el derecho italiano: ¿cómo repercute en el plano sucesorio?
2022
In the Italian legal system, there has recently been recognition by the Constitutional Court in adoptions in particular cases of the existence of civil relations between the adoptee and the relatives of the adopter, thus equalizing the margins of protection of minors, regardless of the situations of fact or law from which the new status of the child originated. This jurisprudential work is full of considerable systematic reflections and is intended to be applied not only to the hypothesis of adoption by same-sex couples, but also to all those cases in which a state of semi-permanent abandonment or cyclical abandonment occurs. Notwithstanding the negative value directed at the forms of surro…
The paradox of the Italian clinical embryologist in the national public health system: hints towards harmonization of a postgraduate educational curr…
2022
Clinical embryologists are highly trained laboratory professionals with multiple roles, including laboratory, clinical, biobanking and quality system management. In most European countries, clinical embryologists are trained to work in Medically Assisted Reproduction (MAR) centres without a specifically dedicated educational path. The criteria required for employment vary according to the educational structure and the public or private nature of the centre. We have herein described the educational profile required by Italian clinical embryologists to work in MAR centres of the National Health System (NHS). Public centres currently represent 36% of all the Italian MAR clinics. According to t…
