According to the in-flight magazine, in Canada it is illegal for a doctor to disclose the gender of a foetus (to the woman bearing it, or anyone else) until the foetus is 24 weeks into term. Naturally there are walk-in clinics in California and Washington that are prepared to do the ultrasound gender determination for a reasonable fee.
Will they make it illegal to travel to another country in order to access medical facilities that are unavailable indigenously? And illegal to own and operate an OB ultrasound machine (Tom Cruise did it, but then there was a bill before senate to make it illegal; I got bored of following the trail)?
The ultrasound operator knows the gender. How is it ethical to withhold this information from the patient?
The other thing I learned on the plane is that people used to terminate pregnancies using slippery elm bark. Slippery elm bark cannot be sold in the UK.
I find myself wholly unequipped (quite possibly in a physical as well as a mental sense) to think about these issues.
