When to refer an infertile mare to a theriogenologist
چکیده انگلیسی

ABSTRACTMost equine infertility cases can be solved with a methodical, thorough physical and reproductive examination and appropriate diagnostic laboratory aids. Repeated examinations may be needed in some cases to identify subtle anatomical abnormalities or irregularities between hormonal and physiological relationships of the reproductive tract. For pregnancy to occur, hormonal signaling must be exquisitely synchronized with physical changes of the reproductive tract and deposition of fertile semen in the uterus. Asynchrony of these events, infection, inflammation, previous trauma to the reproductive tract or “stress” can interfere with conception or maintenance of pregnancy. Infertile mares are presented for three common problems: (1) accumulation of intra-uterine fluid during or immediately after estrus; (2) long standing infection and/or chronic inflammation; or (3) irregular or no estrous cycles. By defining the problem, diagnostics can be chosen to determine the cause. Treatment protocols should be designed around the diagnosis and antibiotics, ecbolics or steroids should not be used indiscriminately. In all cases of mare infertility, semen quality needs to be determined to be satisfactory as a subfertile stallion bred to a subfertile mare greatly decreases the likelihood of pregnancy.
