ΜΕΤΑΒΟΛΕΣ ΙΔΙΟΤΗΤΩΝ ΤΗΣ ΤΡΑΧΗΛΙΚΗΣ ΒΛΕΝΝΑΣ ΤΟΥ ΠΡΟΒΑΤΟΥ ΥΣΤΕΡΑ ΑΠΟ ΣΥΓΧΡΟΝΙΣΜΟ ΤΟΥ ΟΙΣΤΡΟΥ ΚΑΙ ΕΠΙΔΡΑΣΗ ΤΟΥΣ ΣΤΗ ΣΥΜΠΕΡΙΦΟΡΑ ΤΩΝ ΣΠΕΡΜΑΤΟΖΩΑΡΙΩΝ

STUDY OF CERTAIN PROPERTIES (VOLUME, SPINNBARKEIT, CRYSTALLIZATION, PH, SOLID MATTER CONTENT, TOTAL PROTEINS AND RECEPTIVITY OF SPERMATOZOA) OF CERVICAL MUCUSAT VARIOUS STAGES OF THE OESTRUS CYCLE IN EWES AFTER OESTRUS SYCHRONIZATION. IN THE SAME TIME THE CHANGES IN THE ABOVE PROPERTIES WERE CORRELATED WITH THE CHANGES IN THE CONCENTRATIONS OF PROGESTERONE AND OESTRADIOL-17B IN BLOOD PLASMA.ON EVALUATION OF THE RELEVANT RESULTS IT WAS FOUND THAT: THE CHANGES IN THE CONCENTRATIONS OF OESTRADIOL-17B AND PROGESTERONE ARE RELATED TO THE PROPERTIES OF CERVICAL MUCUS, WHILE THE LATTER DETERMINE THE DEGREE OF RECEPTIVITY OF CERVICAL MUCUS TO SPERMATOZOA. OPTIMUM RECEPTIVITY OF CERVICAL MUCUS TO SPERMATOZOA IS OBSERVED DURING THE FIRST HALF PERIODS OF NATURAL OESTRUS. OESTRUS SYNCHRONIZATION IN SHEEP BY MEANS OF INTRAVAGINAL SPONGES MAP OR BY MEANS OF SUBCUTANEOUS PROGESTERONE IMPLANTS DISTURBS THE RECEPTIVITY OF CERVICAL MUCUS TO SPERMATOZOA AT THE FIRST OESTRUS FOLLOWING SYNCHRONIZATION, OWING TO DISTRUBANCE OF ENDOCRINE PATTERN. IN SHEEP SYNCHRONIZED FOR OESTRUS BY MEANS OF PROGESTERONE IMPLANTS AND PMSG OPTIMUM RECEPTIVITY OF THE CERVICAL MUCUS TO SPERMATOZOA IS OBSERVED AT THE ONSET OF OESTRUS WHILE IN SHEEP SYNCHRONIZED BY MEANS OF VAGINAL SPONGES MAP AND PMSG TOWARDS THE END OF OESTRUS.
