A data collection clinical study performed on live human spermatozoa samples. Spermatozoa are imaged by QART Q300TM microscopy system. For the feasibility 1st phase of the study, up to 75 donors are expected to participate. Study group will include sperm samples donated by the clinic's patients (recruited by the investigators from the clinic's patient database) and/or by healthy volunteers (responding to advertisement).

Cells will be individually selected by the system, and will be representative of the cell population to be selected in ICSI procedures. Each selected cell will be imaged by the QART system and independently and blindly reviewed by an Embryologist(s) team. According to these, each cell will be scored as 'Normal' or 'Abnormal' per WHO guidelines. Sperm cells that were successfully imaged with Q300, will be individually stained. Each stained cell will be imaged by BFM and the non-labeled image will be digitally stored (BFM-NL). The BFM-NL Image will be independently and blindly reviewed by an Embryologist team and scored as 'Normal' or 'Abnormal' per their best discretion.

The database generated in this study will be used for (i) testing the performance accuracy of the Q300 system for sperm cell dimensional measurements, (ii) providing feedback to the study sponsor (QART Medical Ltd.) regarding the usability of the Q300 system, (iii) further improving and testing the accuracy of the QART Feature Extraction algorithms and (v) assisting in determining the inclusion/exclusion criteria for subsequent clinical stages. In final validation stages, the conventional staining results will be statistically compared with the Q300 feature extraction results for each individual sperm cell. During the study, ICSI laboratory personnel (at least 10) will evaluate the suggested use scenarios of the device; device components and user interface, the simplicity of use, duration of use, level of expertise required from the Q300 operator, clarity in the use sequences, and perceived added complexity compared with contemporary ICSI routine.
