Microrobotic Gamete/Zygote IntraFallopian Transfer

Project description

Microrobots to assist reproduction techniques

Infertility poses a significant medical challenge, and in vitro fertilisation represents a successful assisted reproduction alternative. However, embryo transfer rates are poor, with only one third of the cases leading to clinical pregnancies. Micro-GIFT is an EU-funded project that will investigate a method for transporting and releasing high-quality zygotes in the fallopian tube. At the experimental level, this approach will ensure a more physiological environment for the embryo timed with endometrial preparation. Researchers will develop microrobots for the non-invasive transfer of zygotes as well as in vivo imaging tools to guide these microrobots in living organisms.

Objective

Infertility is a worldwide problem affecting ~11% of the reproductive-age population. Severe cases are currently treated by in vitro fertilization (IVF) and intracytoplasmic injection techniques (ICSI) with high fertilization rates (~95%). However, embryo transfer is still the critical stage with only 32% of the cases resulting in clinical pregnancies. Moreover, the implantation rates per embryo remain very low (~17%) and often the procedure needs to be repeated several times with no success implying a high economic and social cost. Among the different methods used to overcome this issue, gamete or zygote ntrafallopian transfer (GIFT or ZIFT) seems more promising offering appropriate physiological environment for zygote/embryo development at an optimal synchronization between embryonic and endometrial preparation. However, these methods are invasive and involve surgical procedures and anaesthesia to introduce macroscopic imaging and manipulation tools into the female body, increasing the risk of injury and ectopic pregnancies. The goal of Micro-GIFT is to seek for novel approaches to non-invasively transport and release high-quality gametes/zygotes in the fallopian tube in vivo (mice model). For that multifunctional untethered microrobots (~100 µm size) will be developed making use of smart materials and advanced microtechnologies. However, there are major challenges that need to be overcome to bring this technology close to the clinic, such as the in vivo imaging and control of such microrobots, and their removal after use. The project will also provide deeper insights on the contribution of the fallopian tube on the natural embryo development and implantation, being crucial to create more natural procedures with high success rates. The PI has contributed significantly to the field of sperm-based microbots for assisted fertilization and targeted drug delivery as well as developed a variety of novel microbiosensors for molecular and cellular analysis.
