1 The cervical mucus obtainal from 35 Holstein cows at varying stages of estous cycles and the abnormal situations wew investigated,
2.An attempt was made to find out what factors of pH, cell oontent, sniiltrkeit,
crystallization and electrophoretic ttn of cervical ma might If dat! to and perhaps If responsible for the sperm penetrabthty and survival in vitro.
3.Although exteme acidic or alkaline mucus may repress the sperm penetrability, it seems not very ofn to cause the situation.
4.With increasing spinnIfrkeit of the cervical mucus, the degree of sperm penetration was found to increase
5.As appearing arborization is not surely enhancing sperm migration. Nevertheless a high penet-ative mucus would surely appear the aborization.
6.With increasing leuliccyte content of ma, it would surely repress the sperm penetrability
