It was Travis's own fault, he thought as heentered the house. He had made this who;e situation happen with a wish. There has to be some way he could unmake it with a wish. As he knew, a wish can't reverse another wish, but didn't the note say something about modifying other wishes? Besides, although his wife's penis was the result of a wish, the rest wasn't--why would they be worried about $40,000 when the stone could make money from nothing?
He thought through his wish and then ran into the bathroom to have a moment to make a wish in private. Standing in front of the toilet, he pulled out the magical rock and said "I wish that me and my wife will use IVF to have children together and we have enough money that the cost doesn't matter."
The stone glowed, but something went horribly wrong. At first it seemeed okay--he looked around and he noticed only a slight change to the room. The old shower curtain with the tear in the corner was replaced by a new one, just as Travis would expect if he and Trisha had no money problems but didn't become ultra-rich or anything like that. Then he felt it. He realized he was sitting down on the toilet and he couldn't feel his penis anywhere. He looked between his legs and saw what he felt--had turned into a woman--or at least a mirror image of Trisha, a man who had genitals that belonged on a woman. He was sure there was some scientific name for the condition that the magic of the rock had just invented, like must have happened for Trisha.
Three attempts at wishing away his condition failed and he got up, pulled up his pants, and left the bathroom. Trisha said "I hope you're ready--we have to go pretty soon. What if traffic is bad?"
"Go?" he said.
"To the fertility clinic, of course. You can't have my children otherwise. Everything's on the kitchen table."
Travis ran over to the kitchen table. There were some documents, some indicating previous appointments to a fertility clinic and some other ones that were all about providing information for new patients. He sat down and began to read them. Then he realized what had happened.
In-vitro fertilization means fertilizing the egg in a test tube. If Trisha could produce eggs but couldn't carry a baby, they could use IVF to fertilize her eggs in a test tube and then implant them in another woman. If a man had sperm problems, the sperm could be made to fertilize his wife's egg in a lab, and if a woman could produce eggs but had trouble getting them to the uterus, they could be fertilized and then implanted back in her. If Trisha has male sex organs, IVF would have to be used to fertilize a third party's eggs and implant them in a fourth party, using a surrogate mother.
There was one other situation where it might be used, though--there were cases where a lesbian couple had one partner provide the eggs, used IVF, and implanted them in the other partner. The child would be genetically related to only the first partner, but the other one be pregnant and they would both have a connection to the child. It seemed like that was what was going on, except for the detail that Travis wasn't really lesbian--or was he? His wife's eggs were to be fertilized using a sperm donor and IVF, and then implanted in him. So he and his wife would have a child together using IVF. And needless to say, the first wish was also satisfied since their sex organs were now both female instead of both male and they must still have similar sex drives....
