WebMar 22, 2024 · It provides sperm concentration, motility, and linear and curvilinear velocities by performing an on-phone image analysis using a semen sample loaded into a low-cost disposable microfluidic device. Along with a modular wireless weight scale, it also provides semen volume, total sperm count, and total motile sperm count. WebA sperm is the reproductive cell or gamete produced by the testes. As many as hundreds of millions of sperm cells are conveyed from the testes to the outside of the body in a mixture of secretions from the seminal vesicles, prostate, and bulbourethral glands. Together, the sperm and these glandular secretions are called semen.

WebLinearity, a measurement of how quickly the sperm moves on its forward path (as opposed to just how quickly it moves from side to side or in circles). Beat cross frequency, or how often the head of the sperm moves across the middle of its path. Each of these sperm testing values help lab technicians determine total and progressive motility. WebLinearity of sperm track (linearity (LIN) and/or straightness (STR)) decreased and/or beat cross frequency (BCF) increased only in ACH groups (5 or 20 mg/kg/day), although the percentage of motile sperm, sperm velocities (average path velocity (VAP), curvilinear (VCL), and straight line velocity (VSL)) and amplitude of lateral head displacement ...
