  1. The table shows: viability (%Viab), apoptosis (%Apoptosis) and viable sperm with intact acrosome (%Viable_Acro). Time: immediately after thawing (0 h) and after an incubation of 2 h at 37 °C (2 h). Treatments: Androcoll-Bear 50% (A50), Androcoll-Bear 65% (A65) and Androcoll-Bear 80% (A80). Data shown are the model-derived mean ± s.e.m
  2. (*) Asterisks show differences (P < 0.05) between a specific Androcoll-Bear proportion and its Control
  3. (A,B) Capital letters show differences (P < 0.05) for the same treatment between time (0 and 2 h)
