[The enzymatic activity of the seminal plasma in ejaculates of different fertilities].
Enzymatic ejaculates activity was studied in 15 fertile and 65 subfertile samples of human sperm. The activity of alkaline phosphatase (EC 3.1.3.1), alpha-amylase (EC 3.2.1.1), gamma-glutamyl transferase (EC 2.3.2.2), creatine kinase (EC 2.7.3.2), total lactate dehydrogenase (EC 1.1.1.27) and lactate dehydrogenase-1 was compared to spermogram findings according to 14 morphological and physicochemical criteria of fertility. The enzyme activity depends on functioning of the testes, seminal vesiculae, prostate, bulbourethral glands and is involved in formation of fertility. The findings allowed elucidation of the role of synthesis and some function of spermoplasma enzymes. Practical applications of the above data are discussed in the treatment of male infertility and to raise fertilizing power of the sperm in artificial insemination.
