I think this is interesting but it's annoying that the article bangs on about women rushing into IVF - as some sort of choice because it's "easier" than natural conception. Sorry, but that's utter nonsense!
Also, I found the bit about IVF being "a waste of time" for women whose partners have low sperm counts extremely misleading. My partner has a low count due to previous treatment for testicular cancer and so ICSI was by far our best chance to get pregnant. It's nearly impossible to improve count (no studies that prove it's possible, though things like morphology can sometimes be improved) so without ICSI, not even IVF, we'd have been scuppered. I'd imagine the same thing applies to women with tube problems (all the acupuncture and vitamins in the world are not going to unblock blocked tubes).
In fact, I'm now pregnant after our first round of ICSI and every day I marvel at how medical science has evolved to the point where we have the chance to have a child together and I thank my lucky stars that we live in the 21st century.
And I speak as someone who spent the months leading up to ttc getting into physical shape - folic acid, avoiding alcohol, caffeine and soya, taking vitamins (both myself and my husband) etc - as I do believe that health/diet/exercise improves fertility and general well-being (which can only help in ttc) and I was (and still am) a fan of Zita West, who's got a similar argument to this pair. I then got more and more educated about charting my BBT, EWCM, having acupuncture (both myself and my DH) and trying just about every trick I could (even things like pre-seed, which I definitely didn't need!) as months and months (which turned into years) passed without me getting pregnant. We then had to come to terms with the diagnosis and face up to the tremendously scary prospect of ICSI and grieve for our lost chance to have a family the natural way.
Sorry for the long post, but I feel really strongly that IVF is a tremendous thing that is not taken lightly by the people or doctors involved. However, fertility as a whole does attact a lot of "experts" like these two, who do after all have a product to sell, who make money be setting themselves up in opposition, rather than in conjunction with, mainstream medical science.
Rant over!
