pregnancy chance with vasectomy reversal & fomale conditions

MY HUSBAND IS GOING TO GET HIS vasectomy REVERSED. HE HAD IT DONE OVER 14 YEARS AGO AND HE SAYS HE HAD IT BURNED, CLIPPED AND A GOOD PORTION OF HIS VAS DEFERAN REMOVED. I'M 32 YEARS OLD AND THE DR SAYS I'M FINE FERTILTY WISE ACCORDING TO MY ULTRASOUND, SONOGRAMS AND BLLOD WORK. I DO HAVE CONDITIONS LIKE ENDOMETRIOSIS, ADENMYOSIS, RECURRING CYST,AND A TILTED UTERUS WHICH IS DUE TO THE BIRTH OF MY ONLY CHILD. I GET CHECKED UP OCCASIONALLY THROUGH THE YEARS AND HAVE GOTTEN 3 LAPORASCOPIES TO TREAT SOME OF MY CONDITIONS, CYST, ADHESIONS, ETC. DUE TO THE FACT THAT I WOULD LIKE TO HAVE AT LEAST ONE MORE CHILD. I'M SCARED THAT I MIGHT NOT BE ABLE TO HAVE ANY CHILDREN WITH MY HSUBAND AND IT MAKES ME VERY SAD. ARE OUR CHANCES OF THE REVERSAL VERY SLIM? WE WERE TOLD WE BY A FERTILITY SPECIALIST WHO DID MY BLOOD WORK AND SONOGRAM THAT WE HAD ABOUT A 40% CHANCE. DO YOU AGREE? HE HAS YET TO BE CHECKED IN ANY WAY SHAPE OR FORM.
