This dissertation is divided into three parts. The first part is studies on calcium distribution changes during spermatogenesis, epididymal maturation, capacitation, acrosome reaction, oocyte maturation and egg fertilization using in situ precipitation by potassium antimonate and Ca〓 fluorescent probes at electron and light microscope levels. The main results are: 1 Ca〓 was probably involved in the condensing process of nucleoplasm during spermatogenesis.
