Quantitative sperm characteristics of Tankwa goats with special reference to hyperactivated motility

  • 2020
  • Issue: 5
  • Volume: 50
A. Ngcauzele, G. van der Horst, A. Kotze, T. Jonker & L. Maree Page: 687 - 699

Computer-assisted semen analysis (CASA) is an automated and objective method of evaluating structural (e.g. morphology) and functional sperm parameters (e.g. motility and hyperactivation). Sperm hyperactivation is essential for successful fertilization and is thus an important aspect in determining the fertility…
