In the uterus, muscular contractions may enhance passage of sperm through the uteri...

Commonly, contamination occurs at parturition and to a lesser extent at estrus. Uterine contamination following calving is common, but most healthy cows are able to clear the uterus of bacteria in the first 2 to 3 wk after calving. Persiste...

The upper reproductive tract comprises the fallopian tubes and the uterus, including the endocervix, and the lower tract consists of the ectocervix and the vagina. Immune cells residing in the reproductive tract play contradictory roles: they maintain immunity again...

The lower reproductive tract must accommodate the presence of commensal organisms whereas the upper reproductive tract is sterile. However, the ...
