The pre-diluted sperm sample is automatically transferred from the sample container to the reusable eFlow chamber under the microscope objective. The microscope has a camera, which is connected to a PC with the ANDROVISION CASA software.

Article Snippet: To compare the concentration measurements of different methods, 109 diluted boar semen samples from a commercial AI center were measured for sperm concentration with the NUCLEOCOUNTER, ANDROVISION eFlow and ANDROVISION with disposable counting chambers (Leja, 4-chamber counting slides; 20 μm nominal chamber depth, Leja Products B.V., Nieuw-Vennep, The Netherlands) in a split sample design.

Techniques: Control, Microscopy, Software

Results (mean, SD, minimum and maximum) of sperm concentration measurement with two methods (NUCLEOCOUNTER,  ANDROVISION  eFlow) from 185 raw boar ejaculates. The mean values for sperm concentration did not differ significantly (paired Student’s t-test; P = 0.25).

Bland–Altman plot of split-sample measurements of sperm concentration with ANDROVISION eFlow and NUCLEOCOUNTER (reference method). 95.1% of all measurements lie within mean ± 1.96 SD. The confidence interval (shaded area) of the mean of the absolute differences (± 6.13 × 10 6 , CI = − 2.51 × 10 6 –9.75 × 10 6 ) includes the x-axis.

Comparison of boar sperm concentrations (diluted semen) measurements methods. ANDROVISION eFlow and disposable counting chambers (Leja) were tested against the NUCLEOCOUNTER (NC), respectively. The linear regressions are defined as y = 1.06 + 0.94 × for ANDROVISION eFlow and y = − 3.6 + 1.04 × for ANDROVISION with Leja chambers.
