From what I could find in some googling (I was curious), I think it's a load of hogwash. I could find nothing to support that. I could only find some articles that India banned the use of prenatal ultrasounds to determine the sex of the child. I'd be shocked if someone confirms that lady's story is true. Perhaps the friend was advised against it (there are some studies that question the safety of them). Hopefully someone more knowledgeable will shed more light on it.
