For those attempting O+12 for their girl

i found this today and thought you might want to read as well..may explain whey some women don't get pregnant on O+12 for a while.

The fertile window explained: A man’s sperm can live for up to five days inside a woman’s reproductive tract. A woman’s egg only lives for about 12 hours after it is released. This means that a woman’s egg needs to be fertilized within this 12-hour time frame. Furthermore, freshly ejaculated sperm are not able to fertilize a woman’s egg. It takes time for a process known as capacitation to occur. Capacitation is series of changes that sperm go through once they are inside a woman’s reproductive tract that make sperm more mobile and allow them to penetrate the egg. It can take up to 10 hours for a man’s sperm to complete the capacitation process and be able to fertilize a woman’s egg. This is why the five days before ovulation are so important. Once ovulation takes place, sperm have a very brief window of time to fertilize the egg. Having mature sperm (sperm that have gone through the capacitation process already) ready for the waiting egg is the key to successful conception.

THAT is Soo interesting HappyMedium, I never heard of that sperm process! wOw the miracle of conception is such a fascinating process!

What is interesting about that is that we only dtd one time about 2 hours after when I think I O'd. (timing was not my choice - the only chance we had) So if it took the sperm 10 hours to capacitate that means my egg would have been fertilized at O+12.

Plus, it also takes a certain amount of time even for capacitated sperm to swim/be carried by currents in uterine and tubal fluids to the egg. Sperm don't actually swim most of the way to the egg, they're carried along and they don't get there immediately, it takes time. When we sway we may dry up some of that fluid and make the process take even longer.

Really??? You hadn't read about capacitation before on here? I need to try harder. :(

No, I was dumbfounded when I read that! And no, you do enough! LOL :)
So I want to go through my Vitex Journey and put my sway together for #2 but I'm hesitant to wait till week 12! I remember though that I did the RepHresh and then BD 8 hours later.. I think that was my conception.

I read about it here in one of your essays! It is what Dr. Shettles was ACTUALLY looking at when he THOUGHT he was seeing the difference between male and female sperm! :) I'm paying attention. LOL. I think if you're making a list of cool chicks who pay attention to you, you're going to need to put my name on top of Butterfly's now. Just saying. LOL. ;)

OoOo YA! That's a BIG One!~ It rocked my belief in Dr. Shettles to the core! That's where timing doesn't matter.. they need that special dye under a microscope to distinguish them.

Okay wait, I learned that they have to be mature sperm to fertilize..BUT I thought capatication was a process that they undergo once they enter the vagina? HELP! LOL

Thanks and sorry - I just feel like I talk about capacitation quite a bit and it's a little discouraging to hear people have never heard of it before! ;)

All sperm exit the peener with this little "hat" on that protects and nourishes them for awhile after ejaculation. They can't fertilize the egg wearing that hat and so chemicals in the VJ (or in the fluids that researchers use to wash the sperm with when they want to look at them under a microscope) signal the sperm to dissolve the hat. When this happens, they get smaller and they also get hyperactive and wiggle around frantically, but they don't live as long as the ones with the hats do. They don't all capacitate at the same time - sperm from any one batch seem to be able to communicate with each other in some primitive way and they coordinate things so while any sperm are alive, some are always capacitated and ready to fertilize any egg that arrives on the scene, while others are chillin' with their protective hats on just in case they're needed later on. As far as we know, it is 4 hours at the earliest for sperm to capacitate and it may be longer.

So what Dr. Shettles did, was peered thru the microscope after having washed some sperm and triggered capacitation, and saw some big fat mellow sperm that seemed to live a long time and thought, "Aha, X" and then some tiny hyper guys that died quick and thought "Ah-so, Y" and then basically made up everything based on that faulty premise - that X were big and slow and hardy and lived a long time, and that Y were tiny and swam fast and could be easily damaged due to their size and they died quickly. BOTH timing and pH are based on this notion and it's all a big bunch of crap because it's not even POSSIBLE to tell the diff. between X and Y sperm in a microscope. He was seeing capacitated and uncapacitated sperm and then jumping to a major conclusion which so happened to be totally wrong. Both X and Y are about the same size and live the same amount of time and while we don't know this with 100% certainty, it's likely that there are always some X and Y sperm capacitated at any given time and some X and Y sperm waiting at any given time.

Thank you for sharing. That is incredibly fascinating!!! :)

After hearing that it would make sense why Ovulation at 12 hrs or after is damn near impossible!

Yeah I know I should have said special microscope like an electron one or.... really high powered?
