women may ovlulate more than 1x/month: MUST READ!

[Quirky]

No wonder the rhythm method does not work so well for birth control -- scientists in Canada said on Tuesday they had found women sometimes ovulate several times a single month.

hmmmm... i would be very interested to hear what toni weschler would say. do you think that the signs of fertility such as cervical fluid vary with the multiple ovs.?

that twin thing at the end really freaked me out!!

thanks for posting this!!

Thanks for the post Jane. I am also curious to know if you would be able to see this in your charting. It is a very interesting article.

I swear that's me. I'm the most fertile person EVER.

There's more info about this research here if anyone's interested. It's the paper that was published back in May that sparked the news interest.

I havent read it yet, but thought it would probably have details that are missing from teh somewhat sensationalistic news story.

[runner29]

Not True!!

Sorry for reviving this from the dead, but I came across it and needed to set the record straight!

If you read the actual research article that Aster posted about you'll note that the researchers are talking about the follicles developing before ovulation and that most women seem to have multiple waves of this development.

But, they specifically state: "Only the final wave of each cycle was ovulatory; all preceeding waves were anovulatory." meaning that each woman still only ovulated ONCE in the cycle.

I haven't read the yahoo article (it wasn't on the web anymore) but I work in science and it's pretty common for journalists to miss the most important part of an article or sensationalize something.

Anyway, just to set the record straight! The rhythm method doesn't work because ovulation can be delayed, not because of multiple ovulations. But Fertility Awareness can still work because the last developmental "wave" when ovulation happens will have all the normal fertile signs.

Thanks for the update. I was going to read the actual journal article too, since I also find that journalists tend to miss the point... but now you saved me the work. :LOL

I have read before, possibly in TCOYF (?), that some women do ovulate once and then again within 24-48 hours. This was what happened with one of my super-fertile friends. It did show up as longer fertile EWCM windows and I think there was something funny about her temp too? Hmm, might have to go back and check on that.

Tara-
That's right, I know I've read that before too. I should have mentioned that in my last post. I think it's pretty rare, though. And, it can only happen within ~24-48 hours, like you said, which is why the "rules" in NFP or FAM allow more time than just a day of elevated temperature before the beginning of the safe time, this takes a possible second ovulation into account. But there can't be a bigger gap than that in between the ovulations.

At least once I thought I ovulated twice in a cycle. I don't read temps so I don't have all of that data but usually I am pretty aware of when I ovulate by how I feel and my discharge. I remember I ovulated once as usual and then when it was almost time for my period I think I ovulated again and then my period was delayed 10 days or so. It was pretty odd but I can feel my body trying very hard to get pregnant again without my permission..... hahaha my youngest is almost two and that's been when the 2nd & 3rd were born, so far I am doing pretty good but it hasnt been much fun!

[USAmma]

Hmm that's interesting. when I was charting for ttc, my peak would sometimes last 2 days, other times just 1 day.

I'm a host on another NFP board and I thought I'd post what I wrote over there in response to this article.


My first thought is it was probably sponsored by Pfizer, probably the biggest manufacturer of bcp on the market! 2nd, the study doesn't actually show the women Oing from what I read in the article. It showed movement of the follicles which 'could' theoretically produce an egg, but I don't think they actually saw any eggs. Who's to say that your body doesn't take time to build up to O (which is does, you can monitor the change of hormones in the blood). We all know the rhythm method is flawed, that's not what NFP and FAM are. The ovulation of humans is also not concealed, we are mammals and all mammals have patterns and things that naturally happen when they are fertile. I believe I even read somewhere that we give off pheramones like animals but our noses are just not strong enough to detect them. The article also states the women Oed in several different ways, how many ways are there to drop an egg? The Creighton Method has been studied by Dr Hilgers (fabulous guy) for about 25+ yrs now w/ extensive research and continuing research. What he has found is that this method is MORE effective than hormonal bc. How could that be for over 25 yrs if we have no idea how to detect O in humans? I also used this method to conceive both of my boys on the first try. It worked b/c I KNEW when I was Oing. I'm sure I could go on and on, but I would love to read the actual study to see how flawed it is.


In the Creighton Method they go over about a situation called 'double peak'. This usually happens during time of stress and it lets your body act like it's gearing up to O, only to do the whole thing again in another week or so. This gives you a longer than normal cycle and it's taught you really only O the 2nd time. It's the body's way of protecting itself from a pgcy during an alredy stressful time in your life. I'm glad you all can come here and talk openly about every aspect of our childbearing, it's nice.

I sometimes ovulate more than once in a cycle. My RE refused to believe it until he saw it happen several times via ultrasound.

Have any of you heard of lunar fertility? I don't think it's scientific or anything, but it's kinda interesting!

Jennifer,

do you have anymore info about this?:

I think this might have just happened to me, I was positive I 'O'd on the 23rd, but now I'm a week late, but 2 BFN later, I'm wondering WTH? but if I almost 'O'd on the 23rd and actually 'O'd on the 29th? That would explain the delay, the BFNs (they were too soon), and despite all this might still be pg because we BD that night!

I'm gonna need some ammo on this to prove the (possible) due date!

TIA

I thought when the original paper came out it specifically said that they found that 10% of women ovulate more than once a month?

If women don't occasionally ovulate more than once in a cycle, how do they have dizygotic twins? It's got to happen sometimes.

And there have been documented cases where the children were conceived days apart.

If you were charting or are very in tune with your body, and are pretty sure that you actually O'ed on the 29th, I wouldn't try to get the doc to change the due date... I would just give them a LMP that is 14 days before your O date. Just my two cents, because I knew I o'ed on a day other than day 14 with my son and my OB would not change my due date for anything. Not until an ultrasound confirmed my dates exactly. They are not always open to it. But, if you have a very cool midwife like the one I had with my second PG, I just told her I knew when I O'ed and she believed me. Then again, dates didn't matter so much to her b/c she had no cut-off for overdue babes.

Other reliable indicators to date a pregnancy are the date of your first BFP (if it was done very early) and the early ultrasounds. The ultrasounds done around 20 weeks are only accurate within +/- 5 days, but the early ones are accurate within +/- 2 days I think.

There is info on delayed O'ing in TCOYF and there is info on ultrasound accuracy in Obstetric Myths vs. Research Realities (I think that's the right book).

HTH!

If you read the whole thread, there are others who agreed it does happen... but it is not the same as what the study was claiming. Usually a true double ovulation happens within 12-24 hours of each other. The study was just talking about the development of multiple follicles in waves, but the clarification was that not all those actually getting released... just the final wave. Which is usually one egg but can be two or even (rarely) three!
