Discovery and rescue of rare sperm cell from semen samples
While an normal semen sample contains hundreds of millions of sperm, men with azospermia have no sperm seen and azospermia represents an important cause of infertility. Men with azospermia typically have to use donor sperm in order to have a child. However, extended manual search of semen samples in men with azospermia reveal single-digit numbers of sperm in ~80% of cases. These few sperm are sufficient to fertility eggs in the IVF lab and allow the men to be biological fathers. Unfortunately, the manual search for sperm is only performed in a couple of sites in the world because of the enormous cost associated with having a specially trained andrologist search a sperm sample for roughly 8 hours. In this project, we aim to apply the semen sample to the custom designed microfluidics chip at a fixed flow rate. Next, several thousands of images will be captured at frame rate ranging between 4,000-40,000 fps using a high definition microscope camera as the sample flows through the microfluidics device. We will then build a training dataset of images with and without the rare cells of interest. These training datasets will be used to build an artificial intelligence (AI) model with high accuracy to detect rare cells of interest. The model will be tested for its accuracy on the ‘true’ sample containing rare cells. The Data Science Institute Scholar is expected to have basic programming skills (preferably in Python). Thus, if successful, there will literally be countless babies born as a result of this project.
This is an UNPAID research project.
