Abstract: This study aimed to determine the most reliable method to evaluate capacitation of
buffalo frozen/thawed sperm. Frozen/thawed sperm were incubated in TALP medium in
absence of capacitating agents (control) and in presence of 10 µg/ml heparin for 2 and 4 hrs.
Capacitation was assessed by Trypan blue/Giemsa after lysophosphatidylecholine (LPC)
exposure, chlortetracycline (CTC) fluorescence assay and immune-localization of tyrosine
phosphorylated protein. Furthermore, we evaluated the effect of heparin on penetration
