He went back to the hospital seven days after his castration by his old school friend Julie and her friends. They checked his stitches and gave him a prescription for HRT to keep his testosterone levels normal, or not as he saw fit. He was then given a small plastic jar with his discarded testes floating in a preservative. 

When he asked Julie what she had had done with them she lifted up a gold necklace upon which a gold cast of his testes clattered together. "nice" he said "you intend to do something with these you said" he nodded he'd run through ideas but had finally settled on one that he felt was fitting. I"'ll be back in a week with the finished result" he said with that he left for home and once back went to his mancave he laughed at that thought more like a eunuch cave these days. he dug out the equipment he'd need for his project and mixed up a bunch of clear resin and set that aside while he checked the mould he'd already fromed and then, skewered the end of his severed spermatic cords with a toothpick and then carefully dangled them inside the mould. once he was ready he than began to clowly pour the resin in until if filled the whole thing including the toothpick, he then sealed the top of the mould and set it aside, it would take a few days to cure so he left it alone.

Three days later he carefully took the mould apart revealing an opaque resin blob shaped like a scrotum he then removed the mould lines and began polishing it after several hours of this the resin became clear and there inside the container suspended for everyone to see where his testes forever contained in their new home. He then set them on a wooden plinth with the date of his castration written on it. 

 Once the seven days were up he went back to the hospital and showed Julie his creation, she marveled at the sight and called her friends who all came and took a look they nodded with pleasure at the sight and as he was getting ready to leave a couple of them asked if he could do the same for them in the future. He agreed to do so and from that day forwards he'd get a call to make a permanent desk ornament especially for a good set of testes.
