UCLA lens-free telemedicine microscope adds male fertility testing to its bag of tricks

Lens-free telemedicine microscope
Lens-free telemedicine microscopeTo provide a portable system capable of automatically counting sperm in the field, UCLA researchers have adapted their light-weight, lens-free telemedicine microscope for fertility testing. Through the use of a holographic imaging system, the telemedicine microscope can produce phase and amplitude images of saliva, blood, semen and other fluid samples. The system is capable of instantly counting the number of sperm in a sample, and by comparing 20 holographic images taken over 10 seconds, it can identify which are moving and which are immotile.
The lens-free telemedicine microscope fills an important gap between simple male fertility tests that determine the number of sperm in a sample and more sophisticated systems that also provide information on the movement of individual sperm. This technology provides a portable, automated system for semen analysis which could be used in fertility clinics, in personal male-fertility test kits and for veterinary medicine field applications, such as stud farming and animal breeding.

Ozcan, the inventor of the lens-free telemedicine microscope and an assistant professor of electrical engineering at the UCLA Henry Samueli School of Engineering and Applied Science, is available for interviews. Ozcan is also a researcher at UCLA’s California NanoSystems Institute. For more on his research, visit http://innovate.ee.ucla.edu/.
