Background: Assisted reproductive technologies (ART) are known as a treatment for infertility in which oocyte undergoes manipulation outside body. The aim of this study was to study the evaluation of birth defects in infants conceived through assisted reproductive technologies (ART) and compare them with naturally-conceived infants. Materials and Methods: In this retrospective study, four hundred naturally-conceived infants and 400 infants conceived by ARTs between 20 March and 20 November 2012 in Gha’em Hospital and Sheikh Hospital of Mashhad in Iran participated in this study. Infants were evaluated by a pediatrician at the time of birth, 10 days and 40 days after birth. Correlation between the use of IVF and/or ICSI methods and birth defects was evaluated. Results: Of total 800 infants (450 boys and 350 girls), half of the infants were conceived through natural pregnancy, 200(25%) through in-vitro fertilization (IVF) and 200 (25%) intra- cytoplasmic sperm injection (ICSI). In Infants conceived by IVF, 5 cases (2.5%) had a kind of birth defect just similar to those conceived by ICSI; while 4 cases had birth defects in natural pregnancy. There was no significant correlation between the use of IVF and/or ICSI methods in terms of birth defects (P=0.280).Conclusion: We found that using IVF or ICSI methods is not associated with increasing birth defects.[GMJ.2015;4(4):146-50]

This essay hopes to convey the problematic framework of outcomes for assisted reproductive technologies (ARTs) as they are published today, reframe the logic to focus on human embryo mortality, and quantify a population of human beings generally not accounted for in publicly available in-vitro fertilization data. This analysis, conducted using the CDC’s 2015 National Summary data in conjunction with a retrospective study conducted by one of the nation’s largest ART delivery systems, is one of the first attempts to estimate pre-transfer embryo mortality in IVF. This analysis focuses on fresh non-donor cycles only, that is, rounds of IVF treatment that include immediate transfer of at least one embryo and in which the embryos transferred were engendered using the recipient’s own eggs.

The article discusses the factors that determine the content of the legal limitations of pre-implantation genetic diagnosis in the framework of the in vitro fertilization procedure, taking into account international experience and modern domestic regulatory legal regulation of the field of assisted reproductive technologies. The authors substantiates the conclusion that it is necessary to legislate a list of medical indications for preimplantation genetic diagnosis, as well as the categories of hereditary or other genetic diseases diagnosed in the framework of this procedure.

AbstractDevelopment of assisted reproductive technologies to address infertility has favored the birth of many children in the last years. The majority of children born with these treatments are healthy, but some concerns remain on the safety of these medical procedures. We have retrospectively analyzed both the fertilization method and the microarray results in all those children born between 2010 and 2019 with multiple congenital anomalies, developmental delay and/or autistic spectrum disorder (n = 486) referred for array study in our center. This analysis showed a significant excess of pathogenic copy number variants among those patients conceived after in vitro fertilization with donor oocyte with respect to those patients conceived by natural fertilization (p = 0.0001). On the other hand, no significant excess of pathogenic copy number variants was observed among patients born by autologous oocyte in vitro fertilization. Further studies are necessary to confirm these results and in order to identify the factors that may contribute to an increased risk of genomic rearrangements, as well as consider the screening for genomic alterations after oocyte donation in prenatal diagnosis.

National Legislation

This world literature review tries to determine the significance of the gamete donation in the field of assisted reproductive technologies as well as the availability of treatment methods using donation in in vitro fertilization programs. Gamete donation is regulated by every country's national legislation system, and quite often the laws vary between the states. There are practically no universal standards and/or rules in this area, which, in turn, leads to an ambivalent reaction towards reproductive practices.

Assisted reproductive technologies, such as in vitro fertilization, have made their way to the Middle Eastern nation states. However, in the Sunni-dominant countries, third-party donation of sperm, eggs, embryos, and uteruses (as in surrogacy) is banned, leading some Sunni Muslim couples to travel to Iran and Lebanon, where Shia Muslim clergy have allowed donor technologies.

Retinal Pathology

A review of the literature data is presented, which indicates the possible influence of assisted reproductive technologies (ART) on the formation of both systemic and retinal vascular pathology. Despite the fact that the overall incidence of thromboembolic complications as a result of the use of ART is low, nevertheless, in women included in the in vitro fertilization program, their risk increases by 10 times. Therefore, due to the adverse effect of these drugs on the hemostatic system of a woman, ophthalmologists should be more wary of them in order to detect vascular retinal pathology in a timely manner. Key words: assisted reproductive technologies, in vitro fertilization, hyperestrogenism, vascular retinal pathology.
