LIGHT SCATTERING SPERM ASSESMENT DEVICE AND METHOD

摘要

Test kits for assessing male fertility include a sample holder containing at least one sample chamber, a laser light source, and a light detector to detect scattered light intensity from the sample chamber. The sample holder may include multiple sample chambers connected by sperm swim channels. The test kit may have a housing with a maximum linear dimension of no more than 100 mm. Processing circuitry may be provided that is configured to produce a sperm count and/or sperm motility measurements by processing data from scattered light intensity measurements.

1. An apparatus for assessing male fertility, the apparatus comprising:
a first sample chamber having a perimeter; a plurality of sperm swim channels extending from different positions on the perimeter of the first sample chamber and terminating with a respective plurality of additional sample chambers separate from the first sample chamber and separate from each other; one or more light sources; one or more light detectors positioned to detect scattered light from the first sample chamber and from at least two additional sample chambers when illuminated by one or more of the light sources; and a data processor, wherein the data processor is configured to produce a sperm count based at least in part on detected scattered light.
