This guideline was prepared by the Turkish Society of Reproductive Medicine to define the conditions and requirements for an outsourced preimplantation genetic testing (PGT) programme in line with the experience and needs of practitioners. This guideline is intended to be a reference document for assisted reproductive technology centres, genetic diagnosis centres, non-governmental organizations working on reproductive health, legal experts, consultants working on laboratory accreditation, academicians specializing in ethical issues, and policy makers. The Consortium aims to provide recommendations addressing the challenges of genetic testing, especially PGT for monogenic diseases (PGT-M) due to the high rate of consanguineous marriage in Turkey. For this purpose, this summary document specifically includes challenges and recommendations regarding PGT-M practice, and aims to identify and aid in prevention of errors leading to misdiagnosis. The recommendations can be modified to fit other locations., (Copyright © 2024 Reproductive Healthcare Ltd. Published by Elsevier Ltd. All rights reserved.)

As interest in deep space travel grows exponentially, understanding human adaptation in becoming an interplanetary species is crucial. This includes the prospect of reproduction. This review summarizes recent updates and innovations in assisted reproductive technologies (ART) on Earth, while also discussing current challenges and areas for improvement in adapting ART studies to the space environment. We discuss the critical components of ART - gamete handling and preparation, fertilization, embryo culture, and cryopreservation - from the daily practice perspective of clinical embryologists and reproductive endocrinologists and lay out the complicated path ahead.In vitro embryo development in low Earth orbit and beyond remains questionable due to synergetic effects of microgravity and radiation-induced damage observed in simulated and actual in-space mammalian studies. Cryopreservation and long-term storage of frozen samples face substantial obstacles - temperature limitations, lack of trained personnel, and absence of adapted cosmic engineering options. We touch on recent innovations, which may offer potential solutions, such as microfluidic devices and automated systems. Lastly, we stress the necessity for intensive studies and the importance of an interdisciplinary approach to address numerous practical challenges in advancing reproductive medicine in space, with possible implications for both space exploration and terrestrial fertility treatments., (© 2024.

Fifteen percent of couples of reproductive age suffer from infertility globally and the burden of infertility disproportionately impacts residents of developing countries. Assisted reproductive technologies (ARTs), including in vitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI), have been successful in overcoming various reasons for infertility including borderline and severe male factor infertility which consists of 20%-30% of all infertile cases. Approximately half of male infertility cases stem from suboptimal sperm parameters. Therefore, healthy/normal sperm enrichment and sorting remains crucial in advancing reproductive medicine. Microfluidic technologies have emerged as promising tools to develop in-home rapid fertility tests and point-of-care (POC) diagnostic tools. Here, we review advancements in fabrication methods for paper-based microfluidic devices and their emerging fertility testing applications assessing sperm concentration, sperm motility, sperm DNA analysis, and other sperm functionalities, and provide a glimpse into future directions for paper-based fertility microfluidic systems., Competing Interests: The authors declare the following competing financial interest(s): S.T. is a co-founder of and has equity interest in GetDeHealth, a company that is developing microfluidic technologies for point-of-care diagnostic and wellness solutions.
