what is the difference between CASA Sperm Semen Analysis System IMV CEROSII and Hamilton IVOSII

The CASA (Computer-Assisted Sperm Analysis) systems IMV CEROS II and Hamilton Thorne IVOS II are both widely used in human fertility clinics and animal breeding laboratories to analyze sperm motility and morphology. While they serve similar purposes, they have some differences in hardware design, software interface, analysis algorithms, and target markets.

1. Manufacturer Overview:

• IMV CEROS II:

  • Developed by IMV Technologies, a French company specializing in reproductive biotechnology, particularly for animal breeding (e.g., swine, bovine, equine).

• Hamilton Thorne IVOS II:

  • Developed by Hamilton Thorne, a U.S.-based company well known for its applications in clinical human IVF as well as animal reproduction.

2. Key Differences:

Feature	Hamilton Thorne IVOS II	IMV CEROS II
Target Use	Clinical IVF (human), Animal breeding	Primarily animal breeding
Software Focus	Human morphology standards (WHO), advanced human IVF tools	AI-based motility & concentration tools for animals
Integrated System	All-in-one system with built-in computer and monitor (standalone)	Modular system – connected to external PC or laptop
User Interface	Touchscreen friendly, streamlined for IVF workflow	Flexible but more geared for research/animal labs
Sample Types	Human semen, also adaptable for boar, bull, stallion, etc.	Specially designed modules for different animal species
Chamber Slide Compatibility	Compatible with Leja, Hamilton slides, and others	Works with standard IMV slides and compatible third-party
Custom Parameters	Deep settings for sperm morphology (strict Kruger, etc.)	Advanced motility, concentration tracking (animal focus)
Reporting	IVF-specific reports, patient database integration	Genetic selection metrics for breeding programs

3. Technical Notes:

• Hamilton IVOS II offers more advanced tools for morphology and morphology grading, critical in human fertility clinics.

• IMV CEROS II is favored in animal AI centers and breeding stations due to its flexibility with species-specific semen parameters.

Which to Choose?

• For Human IVF Labs → IVOS II is typically preferred due to its WHO standard compliance, advanced morphology assessment, and user interface tailored for clinical workflow.

• For Animal Breeding (boar, bull, stallion, etc.) → CEROS II offers better integration with animal-specific semen analysis and genetic selection tools.
