spiral, my take-aways from the article, here is my long essay:
- avoid old eggs and sperms: i think this is logical cos the eggs and the sperms will degenerate over time. Not forgetting the womb lining must not be too old for implantation to happen. For those ttc thru natural intercourse, i think it is worth taking the lifespan of the sperms into considerations. However, for those of us doing IUI, this does not apply. The sperms used in IUI are processed and they can only survive 24 hours. There again, the part on the freshness of the egg is something new that i have learnt, those of us doing IUI may wanna take note of this. Before reading this article, i had the impression that IUI will be more effective after ovulation has just occurred. Seems like it may not be true afterall. And do u know that if u wanna girl, the sperm should wait for the egg cos the sperms carrying the X chromosomes (for girls) travel slower but survive longer than those of Y chromosomes (for boys)!! Knowing this makes me feel a bit more hopeful cos in this cycle, my follicles have not ovulated (but should be soon after IUI cos i had HCG jab and my follicles are already very big!) when IUI was performed.
- building up sperm count: hmmm... all along i thought the longer the man accumulate, the more sperms he will produce heeheee... from the article, it seems like freshies are better! i think it all boils down to having healthy eggs and sperms. If these 2 are healthy, then the chances for fertilisation and implantation will be higher. Dun forgot, after ovulation, the follicles collapse and released the egg, leaving behind the corpus luteum, which is responsible for the production of progesterone in early conception before the signal reaches the brain to produce progesterone. So, if the egg and sperm are not healthy, i am quite sure this will affect the quality of the corpus luteum, which in turn has an adverse effect on the progesterone level (ie. low)
- chances of conceiving 17 days post ovulation: i think this make sense. The womb would be too old by then to sustain the pregnancy. i heard this from my previous gynae. But he din mention 17 days DPO as a benchmark. i would think the author based on her own experience to deduce the number 17, so it may not always apply to everyone cos our bodies are all very different. i would think the safest would be to ovulate at around 14 DPO, that's wat i heard from most gals. i suspect i might have this problem, cos i used to ovulate at around 16-17 DPO... This cycle, i am on metformin and clomid, and this is the first time i ovulate 12 DPO... strange hor.
- bbt post ovulation should rise as soon as possible: this one, i've always believe. i heard this from a TCM physician. The reason he gave is that if the bbt rise is very slow (say take a few days), it means that the corpus luteum is not producing progesterone fast enough for pregnancy to occur. He actually said that it will be ideal if the bbt rises sharply one day after ovulation!!! *sigh* again i have this problem, cos i always have to wait for 3-4 days for a significant rise in bbt!
Rest of u, wat do u think?
