spiraling piece of metal coiled around the tail of the sperm. The motor, which acts as an on-board power supply, guides the sperm through a magnetic field, making it easier for them to swim towards the egg. According to the researchers, the motor detaches from the sperm tail when the sperm reaches the egg for fertilization, and the magnetic field does not hurt any of the cells involved, making it perfect for use on live tissue.
The motors were effective in successfully transporting the healthy sperm from one spot to another while inflicting minimum harm to the sperm during lab trials. This technique would be more economical than other types of assisted reproduction, which may turn out to be costly for each round. However, so far, there have been no human tests with this technique because this nanotechnology is not yet feasible.
Moreover, the researchers are still not clear as to how the immune system of the woman will respond to micromotors put into her body, and the small motors get stuck on sperm’s tails and decline to release their cargo. However, the study serves as an excellent indication of what future infertility therapies may involve once we have the appropriate tools and knowledge to make it happen.
