To illustrate the influence of kallikrein on the hypoosmotic swelling test, 84 human semen samples were classified into 4 groups: normospermia (n = 34, group A), oligospermia (n = 18, group B), asthenospermia (n = 8, group C), and oligoasthenospermia (n = 24, group D). Two aliquots of 0.45 ml were prepared from each specimen in all the groups: one was incubated for 3 hr in a glass tube containi...
