Advances of microfluidic technology in reproductive biology

According to World Health Organization (WHO) reports about 70 million couples suffer from infertility all over the world. A lot of research groups are working on this issue and have made therapeutic approaches by integrating biology, medicine, genetics, chemistry, psychology, mechanic, and many other branches of science. However, these methods have their own pros and cons. Assisted Reproductive Technologies (ART) has appeared to solve infertility problems. In Vitro Fertilization (IVF), Intracytoplasmic Sperm Injection (ICSI), Intrauterine Insemination (IUI) are the most common and conventional technologies in this regard. There are at least two characteristics of microfluidics, mechanical and biochemical, which can be influential in the field of mammalian gamete and preimplantation embryo biology. These micmfluidic characteristics can assist in basic biological studies on sperm, oocyte and preimplantation embryo structure, function and environment. Using micmfluidics in sorting sperm, conducting different steps of oocyte selection and preparation, and transferring embryo by passing sub-microliter fluid through microchannels results in low cost and short time. The size and shape of microchannels and the volume of used fluid differs from non-human cells to human cells. The most progressions have been seen in animal models. Results suggest that microfluidic systems will lead to improved efficiencies in assisted reproduction.

Automated summary

According to the World Health Organization, approximately 70 million couples worldwide suffer from infertility. Research teams have integrated various scientific branches to develop therapeutic approaches, with Assisted Reproductive Technologies (ART) being a key solution. The use of microfluidic technology has shown significant progress in improving efficiency in assisted reproduction.
