Clinicopathologic diagnosis of mycoplasma endometritis

Chronic endometritis and its association with cervical colonization by Ureaplasma urealyticum was investigated in a group of 28 infertile patients treated for infertility problems. Twenty had positive cervical cultures for U. urealyticum and eight had negative cultures. There was focal chronic endometritis in 11 of the endometrial biopsies of the 20 cases with positive mycoplasma cultures. Ten of these biopsies were in the secretory phase, and one was in proliferative phase. No case with a negative culture showed endometritis.
