Validation of a smartphone-based, computer-assisted sperm analysis system compared with laboratory-based manual microscopic semen analysis and computer-assisted semen analysis

Abstract

Purpose: This study aimed to evaluate the clinical efficacy of a portable smartphone-based system for computer-assisted semen analysis (CASA) compared with the results of manual microscopic semen analysis (SA) and laboratory-based CASA for self-evaluation of semen parameters by a male partner. Materials and Methods: From July 2017 to February 2018, a total of 28 samples were analyzed for concentration and motility with a smartphone-based CASA system and the results compared with those from laboratory-based CASA and manual microscopic SA with a Makler Counting Chamber (SEFI Medical Instruments, Israel). Results: Sperm concentration and motility measured with the smartphone-based CASA system were positively correlated with the microscopic-based results. Likewise, sperm motility calculated with smartphone-based CASA was positively correlated with the laboratory-based CASA results. These results suggest that the smartphone-based CASA system can be used for clinical semen diagnosis. Conclusions: A portable smartphone-based CASA system can play a role in motivating infertile males to visit clinics, thus resulting in early diagnosis and treatment with cost-effectiveness. The device can be used for easy follow-up on a screening basis by the male partner before visiting a clinic for fertility evaluation or by infertile males after receiving medical management. Additionally, future software advancements and post-marketing consumer surveys will make possible wider applications, including assessment of sperm morphology, in the coming future.
