Blood samples and endometrial biopsies were taken from 96 barren thoroughbred mares to verify if there is a relationship between biochemical markers and histologic features. Sera obtained from blood samples were used for polymorphysm determination of transferrin (Tf), esterase (Es) and protease inhibitor (Pi). Biopsy samples were classified in GI, II or III according to their histopatological features. Mares with GI, II and III classification had F1 (34,86%), F2 (35,29%) and F1 (33%), respectively, as the most frequent Tf alele. Alele I was the most frequent Es alele in mares with bipsies classified as GI (84%), GII (88%) and GIII (100%).The most frequent Pi alele in GI (49%), GII (47%) and GIII (50%) was L. Tf genotypes observed most frequently were DF1, F1F2 and F1; Es most frequent genotype was I and Pi’s L and LN. Most mares had a heterozygous Tf (75%) and Pi (67%) genotype and a homozygous Es genotype (78%). Regardless of their age (6 to 12 or 13 to 21-y-o) most mares had GI endometrial biopsies. There was no significant relationship between age groups, Tf, Es and Pi and endometrial biopsies or reproductive problems in thoroughbred mare.
