“That’s exactly what I’m suggesting,” Marissa said. “I didn’t have TB salpingitis either. I had a deliberate inoculation with BCG vaccine. I think the basis of this whole mystery is nothing but business interest. A few years ago, Female Care Australia realized that they were sitting on a potential gold mine with their IVF technology. The only trouble was that their increased success was denying them income by lowering revenue. So they decided on two courses of action to ensure increased revenues. One was to create more demand. The only absolute indication for IVF is hopelessly blocked fallopian tubes. Someone found out that the rural Chinese doctors had been clever enough to develop a way of cannulating the fallopian tubes without the need for anesthesia. So they began bringing these doctors out of China to do just what they had been doing in China: sterilizing women. The trick was to sterilize without leaving evidence of it, or leaving evidence that could be misinterpreted. Someone must have come up with the BCG vaccine. It causes an intense immunologic reaction that seals the tubes totally and destroys the organisms in the process. That’s how BCG works. On biopsy, it looks like tuberculosis. There just aren’t any organisms. Obviously, they only tried this ploy on certain candidates. They chose only young, recently married, middle-class females. All they had to do was schedule these women for a minor procedure of some sort, like a cervical biopsy. I know that one ruse was to tell the patient that her Pap smear was CIN Grade #1. That’s how they got me and Wendy. Neither Wendy nor I had told the clinic we were physicians. If they had known, they probably wouldn’t have risked including us in the scheme. And they certainly didn’t know about Evelyn Welles’ immunological problem. And Rebecca Ziegler. She must have been clever enough to figure that something was wrong. I think they killed her and made it look like a suicide.

“The second part of the plan to maintain revenue was to make sure that the IVF wasn’t successful too quickly. At ten thousand dollars per cycle, you can see why they’d want to run their patients through as many cycles as possible. Yet ultimately, they wanted all their patients to conceive. That meant a better reputation for them. My guess is that to make failed cycles a certainty, they just added a drop or two of acid to the culture media after fertilization took place. Before my last egg transfer, I asked to see the zygotes. I remember the solution was crystal clear. The significance of the color didn’t dawn on me until just recently. The usual pH indicator in tissue culture media is phenol red, which turns clear in acid. My embryos were in acid. No wonder they didn’t implant.”
