Microdissection testicular sperm extraction (TESE) is an invasive surgical procedure in which sparsely located healthy larger diameter tubules carrying viable spermatazoa are identified by visual examination of the seminiferous tubules of the infertile testis under a microscope, and biopsies of regions of interest are performed. In this paper, we report on microfabricated silicon microprobes integrated...
We report on a microfabricated silicon microprobe integrated with an ultrasonic actuator and polysilicon strain gauges for microdissection testicular sperm extraction (TESE) surgery. Insertion experiment was performed on rat testis tissue and by monitoring the tubule puncture artifact in the force signal sensed by the microprobe, we were able to estimate the average diameter of the sperm-carrying...
