Obstetric practices in NZ follow close on the heels of those in larger countries like the USA. Most women in NZ now have at least 4 ultrasound scans during their pregnancy with at least 2 of these being performed in the first trimester. In NZ most women access fully subsidized pregnancy/maternity care and those who pay privately for obstetric care still have their (usually much greater number of) scans publicly subsidized. The continuing increase in ultrasound scanning is greatly increasing the cost of maternity care to the NZ taxpayer with no commensurate improvement in outcomes. Like the rest of the developed world, where ultrasound is readily available, we are seeing an increase in autistic spectrum disorders and also things like tongue and lip tie. More regulation, research and consumer education is urgently needed. We hope the USA will lead the charge to ensure the safety of this overused technology.
According to this study, mouse brains exposed to diagnostic ultrasound grew incorrectly. This is brain damage during development.
Developing brain cells have to migrate from a starting location to a distant one, where they link up to other cells. This study suggests that ultrasonic exposure can disrupt this, knocking cells around and leading to mis-connections.
00:00:03 To find out how to dilute a man’s knock-up sauce without permanent damage, we asked the doctor.
00:00:09 – If men are engaging in unprotected sex, they might want to be temporarily infertile.
00:00:15 announcer: SO How can they do that?
00:00:17 A man could try blasting his sack with an ultrasound machine.
00:00:21 According to the university of north carolina, zapping a bro’s crotch with ultrasound waves for just ten minutes could kill his sperm for up to six months!
00:00:31 But there’s a catch.
00:00:32 Hitting some high notes on his tweeter can close his sperm tube permanently.
00:00:37 both: AH!
I saw this recently on SpikeTV and it had me cracking up hard enough that I had to share it.
I visited the ultrasound labs at UNC Chapel Hill personally and met several people who worked there. I am concerned that ultrasound use on gonads would change hormone levels in adults. In the literature, there is evidence that ultrasound exposure to rat gonads alters their testosterone levels … reference: http://revistas.um.es/hh/article/viewFile/130341/121361
