My cousin couldn't concieve for years & years she eventually fell pg through IVF well into her 30's then after many FET's she was about to do another full stim cycle and she fell pg naturally.
I'm sure there is something in this. Yes it won't be the case for everyone, but I'm amazed at the stats in my gang alone!
So, I have 4 friends who've done IVF, after variously TTC 2-5 years.
2 friends had successful fresh transfer and live birth. And both of them later fell preg naturally about a year after having the first IVF bub.
1 friend had unsuccessful fresh transfer, no frosties. The following month, she fell naturally. (She had been TTC for 5 years).
The 4th friend had first naturally, then 2 x IVF, so not as interesting.
I guess all of these girls were subfertile rather than infertile. The one who tried for 5 years is convinced that the hormones she injected for IVF were what she needed to kick her reproductive system into gear.
I'd love to know if a study has been done on this phenomenon.
Her and hubbie had unexplained infertility and TTC for 8 years and tried everything then moved onto IVF where they had 1 daughter but she passed away at 18 months then they had another daughter by IVF and deided that becasue they have some embryos still frozen to have them transferred and they had another daughter from that. They never used protection after that and fell pragnant when their daughter was 10 months old naturally! She is due to give birth in 2 weeks and is 38 and hubby is 40.
Google to the risk...this BBC article on this very topic is very interesting.

Infertility doctors have long been aware of "spontaneous conception" - a naturally occurring pregnancy after the birth of a child conceived through in vitro fertilisation.
Now a Japanese study points to who is most likely to benefit from the effect.
It found that overall there was an 18% chance of spontaneous conception after IVF treatment, but that the likelihood rose to 37% among women under the age of 27.
This is abit different but I recently looked after a woman (as a midwife) who has 7 IVF attempts. I think 3 were stim cycles and the rest FET. Well she said she couldn't afford any more and then 12months later fell pregnant naturally. They couldn't believe how it happened (deep discussion with the Obby about it.) It wasn't all smooth sailing she had a stitch in at 26weeks (very scary) and recently gave birth to a gorgeous baby girl at 38weeks.
Certainly a common phenomenon - and I think the effect pregnancy can have on regulating hormones can certainly help. The same can be said for couples who spend years TTC naturally, eventually do, and then 6 or so months after giving birth, discover they are pregnant again.
One theory is that couples (chiefly women) going through IVF are so vigilant with their diet and exposure to toxins etc, that they actually eradicate a large portion of toxicity that their bodies were previously holding onto, and hence created a barrier to conception.
This vigilance usually carries through to the pregnancy, and particularly if the woman breastfeeds, this triggers the body to metabolise and release an even greater proportion of toxins (heavy metals, pesticides, personal care chemicals etc) so the body is more 'primed' for natural conception at the end of this experience than it was prior to the TTC journey.
So too do men learn alot about the way various lifestyle and environmental factors effect the health of sperm when going through the IVF process and are more likely to have made various changes which are hospitable to natural conception occuring down the track.
