13. Análise crítica sobre a evolução das normas éticas para a utilização das técnicas de reprodução assistida no Brasil
Resumo O Conselho Federal de Medicina (CFM) publicou em 1992 a resolução CFM nº 1.358/1992 com o objetivo de adotar normas éticas para utilização das técnicas de Reprodução Assistida (TRA). Esta resolução foi atualizada em 2010 (CFM nº 1.957/2010), em 2013 (CFM Nº 2.013/13) e teve sua última atualização 2015 (CFM nº 2.121/2015). O objetivo d

14. La regulación de las tecnologías reproductivas y genéticas en Argentina: análisis del debate parlamentario
Abstract This article analyzes the parliamentary debate held towards the legal regulation of reproductive and genetic techniques in Argentina (RGT). It examines the discussions in the national congress regarding the Law for Medically Assisted Reproduction, which was sanctioned in 2013, and the debate in both legislative chambers over Art. 19, which concerns

15. Marker-assisted screening of breeding populations of an apomictic grass Cenchrus ciliaris L. segregating for the mode of reproduction
Abstract Cenchrus ciliaris L. is an apomictic forage grass grown in pastures and rangelands of the semi-arid tropics. It reproduces predominantly through apomixis; rarely, obligate sexual plants have also been reported. Absence of sexual reproduction limits the possibility of genetic improvement through hybridization. This study reports on hybridization of a

16. Highly prevalence of vitamin D deficiency among Brazilian women of reproductive age
ABSTRACT Objective Vitamin D has several metabolic functions and possible reproductive functions. This study aimed to determine the prevalence of vitamin D deficiency among Brazilian women of reproductive age, and to evaluate the relationship between serum 25-hydroxyvitamin D [25(OH)D] concentrations and infertility causes. Subjects and methods This retr

17. Practices and ethical concerns regarding preimplantation diagnosis. Who regulates preimplantation genetic diagnosis in Brazil?
Preimplantation genetic diagnosis (PGD) was originally developed to diagnose embryo-related genetic abnormalities for couples who present a high risk of a specific inherited disorder. Because this technology involves embryo selection, the medical, bioethical, and legal implications of the technique have been debated, particularly when it is used to select fe

18. Gonadotropin therapy in assisted reproduction: an evolutionary perspective from biologics to biotech
Gonadotropin therapy plays an integral role in ovarian stimulation for infertility treatments. Efforts have been made over the last century to improve gonadotropin preparations. Undoubtedly, current gonadotropins have better quality and safety profiles as well as clinical efficacy than earlier ones. A major achievement has been introducing recombinant techno

20. Predictive factors for sperm retrieval and sperm injection outcomes in obstructive azoospermia: do etiology, retrieval techniques and gamete source play a role?
Obstructive azoospermia is a relatively common male infertility condition. The main etiologies of obstructive azoospermia include congenital, surgical-derived, traumatic and post-infectious cases. Although seminal tract reconstruction is a cost-effective treatment in most cases, this approach may not be feasible or desired in some cases. In such cases, assis

21. The role of varicocele treatment in the management of non-obstructive azoospermia
The literature on male reproductive medicine is continually expanding, especially regarding the diagnosis and treatment of infertility due to non-obstructive azoospermia. The advent of in vitro fertilization with intracytoplasmic sperm injection has dramatically improved the treatment of male infertility due to nonobstructive azoospermia. Assisted reproducti

22. Cryopreservation of testicular and epididymal sperm: techniques and clinical outcomes of assisted conception
The introduction of the technique of intracytoplasmic sperm injection to achieve fertilization, especially using surgically retrieved testicular or epididymal sperm from men with obstructive or non-obstructive azoospermia, has revolutionized the field of assisted reproduction. The techniques for the retrieval of spermatozoa vary from relatively simple percut

23. Biotechnological approaches to the treatment of aspermatogenic men
Aspermatogenesis is a severe impairment of spermatogenesis in which germ cells are completely lacking or present in an immature form, which results in sterility in approximately 25% of patients. Because assisted reproduction techniques require mature germ cells, biotechnology is a valuable tool for rescuing fertility while maintaining biological fatherhood.
