Penetration of human ejaculated spermatozoa into human and bovine cervical mucus. I. Correlation between penetration values.
Midcycle bovine cervical mucus (BCM), fresh (FBCM) or frozen at -20 degrees C (BCMF), and human cervical mucus (HCM) were collected and tested in in vitro penetration tests, using human ejaculated spermatozoa of good quality. Penetration tests were performed at 34 degrees C for 1 hour, and the penetration value (PV) was calculated. Duplicates of each run were in a narrow deviation. Correlations between PV rates of the same semen samples in the 3 sources were found to be significantly high (HCM versus FBCM, r = 0.958; HCM versus BCMF, r = 0.982, and FBCM versus BCMF, r = 0.985), suggesting that human ejaculated spermatozoa penetrate the cervical mucus of all three sources at the same rate.
