Device Description
Semen Quality Analyzer integrates optical design and image analysis and combined with artificial intelligence image processing method, to fully automated analysis of semen quality including sperm pH, semen concentration, motility, and morphology. The images are captured and recorded by cameras and with image processing methods, the locations of sperms are detected. The sperm concentration is analyzed by the sperm unit density; the sperm motility is calculated by tracing sperm trajectories and the sperm morphology is calculated by comparing head and tail percentage. Through camera, the chromatographic image of pH is captured and with image saturation and brightness analysis, the level of pH is determined.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Verification and validation of test results were evaluated to establish the performance, functionality and reliability of LensHooke X3 PRO Semen Quality Analyzer and LensHooke X3 PRO SE Semen Quality Analyzer. The evaluation included repeatability, reproducibility, LoB/LoD/LoQ, linearity, interference, matrix comparison, sample volume, operating conditions and stability.
System Accuracy Study and User Performance study
The user performance study was performed to demonstrate that English speaking and reading adult lay users including male and female across different education backgrounds can easily understand and follow the labeling/user instructions to obtain accurate results while using Subject Device. The study was performed using Point-of-Care professionals or licensed registered nurses to obtain POC test findings. LensHooke X1 PRO Semen Quality Analyzer performed by POC personnel was used as reference method. The study results demonstrate that the layperson user accuracy and ease of use (via participant questionnaire scoring) of subject device.
Key results: Results of performance evaluation of LensHooke X3 PRO Semen Quality Analyzer and LensHooke X3 PRO SE Semen Quality Analyzer demonstrate that the subject devises are substantial equivalence to the predicate device, LensHooke X1 PRO Semen Quality Analyzer and LensHooke X1 PRO SE Semen Quality Analyzer.

Dear Clare Huang:
We have reviewed your section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (the Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database available at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.
If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898.
