: Assisted Reproductive Technologies (ART) has significantly improved the chances of pregnancy. In Vitro Fertilization (IVF) remains the most widely used ART procedure, which involves a series of steps like ovarian hyperstimulation followed by vaginal oocyte retrieval and in vitro fertilization of the oocytes with sperm, culture of the embryos, and the final transfer of the embryo to the recipient or surrogate recipient. Intracytoplasmic sperm injection (ICSI), another form of ART, is developed to circumvent the problems encountered in IVF. However, the studies have indicated that only about one-third of ART cycles result in live births. This review is designed to provide a comprehensive idea about advances in reproductive medicine in terms of preparation of gametes and implantation.

Further Development

The increase in the frequency of using assisted reproductive technologies (ART) dictates the need for pre-implantation diagnosis of embryos to determine which of them are euploid and recommended for embryo transfer (ET), since the main cause of implantation failures when using in vitro fertilization (IVF) is ET aneuploid or mosaic ETs or mosaic imitations that use in vitro fertilization (IVF) is ET aneuploid or mosaic imitative failures when using in vitro fertilization (IVF) is ET aneuploid or mosaic imitations. . For this purpose, the PGT-A technology was created, since the appearance of which and its further development there have been discussions about the feasibility of using PGT-A for each pair, which turned to the use of ART. The purpose of this literature review is to describe the current status of PGT-A and determine the prospects for its widespread adoption in the practice of reproductive medicine. A literature search was carried out in the PubMed and Cochrane databases for the last 10 years. An analysis of the literature has shown that IVF with PGT-A technology has significant advantages over traditional IVF; The technology has a number of technical and financial limitations, which makes it difficult to massively introduce technology into the practice of reproductive medicine, therefore at this stage there should be clear indications for using IVF with PGT-A.

Therapeutic Measures

Over the years, the efficacy of assisted reproductive technologies has significantly improved. Infertility-associated problems like tubal obstruction, severe male-factor infertility, severe endometriosis and ovulatory dysfunction have entailed the need for in vitro fertilization (IVF). Intracytoplasmic sperm injection (ICSI) is the insertion of a single and viable spermatozoon into the oocyte, thereby circumventing the penetration of the oocyte membranes and aiding gamete fusion process. The use of in vitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI) are the most commonly practiced therapeutic measures. However, owing to the report-based outcomes, the success rate is still inconclusive. Besides, there are reports on low pregnancy rates after ICSI, using round spermatids from men, in the absence of elongated spermatids in testes. The use of elongated and round spermatids in ICSI procedures has raised some reasonable doubts regarding the safety of this treatment. In this review, we will give a comprehensive discussion on the role of IVF/ICSI for the treatment of infertility, based on the current researches.

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.

Nation States

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.
