Abstract

Infertility is a state of the male or female reproductive system that is defined as the failure to achieve pregnancy even after 12 or more months of regular unprotected sexual intercourse. Assisted reproductive technology (ART) plays a crucial role in addressing infertility. Various ART are now available for infertile couples. Fertilization in vitro (IVF), intracytoplasmic sperm injection (ICSI) and intrauterine insemination (IUI) are the most common techniques in this regard. Various microfluidic technologies can incorporate various ART procedures such as embryo and gamete (sperm and oocyte) analysis, sorting, manipulation, culture and monitoring. Hence, this review intends to summarize the current knowledge about the application of this approach towards cell biology to enhance ART.

Highlights

  • About 7% of couples worldwide suffer from infertility conditions [1]

  • Assisted reproductive technology (ART) includes all treatments and medical procedures that include the handling of eggs and embryos to address infertility

  • Groups of two embryos per microfluidic well successfully developed to the blastocyst stage, at a rate of over 80%

Summary

Introduction

Assisted reproductive technology (ART) includes all treatments and medical procedures that include the handling of eggs and embryos to address infertility. ART can increase the genetic quality of livestock, produce transgenic animals, assisting in cloning and artificial insemination, reduce disease transmission, preserve endangered germplasm, produce chimeric animals for disease research and treat infertility. It can improve fertility through artificial treatments, including fertilization in vitro (IVF) [2], gamete intra-fallopian transfer (GIFT), pronuclearstage tubal transfer (PROST), tubal embryo transfer (TET), zygote intra-fallopian transfer (ZIFT), intrauterine insemination (IUI) and intracytoplasmic sperm injection (ICSI) [3]. The most typical ART methods are fertilization in vitro (IVF) and intracytoplasmic injection of sperm (ICSI) [4]
