Implantation Dip (ID) dan Corpus Luteum Dip (CLD)

Assalamualaikum dan Salam Sejahtera...

 
Suhu turun, bermakna Corpus Luteum diarahkan untuk penghasilan progesterone bagi penebalan dinding rahim di mana persediaan bagi proses penempelan. Corpus Luteum adalah saki baki folikel selepas pengeluaran telur. Tidak semua akan mengalami CLD. Jika anda mengalami CLD, suhu akan drop (sesiapa yang berBBT boleh alert suhu drop ataupun tidak) tanda estrogen drop dan Corpus Luteum akan menghasilkan progesterone, seterusnya suhu akan kembali tinggi.
CLD ---> Estrogen turun, Progesterone meningkat
*CLD hanya berlaku sekitar DPO 2 hingga DPO 5.

Bagi Implantation Dip (ID) pula berlaku sekitar DPO 7 hingga DPO 12. Ianya berlaku bila zigot (telur yang telah bersenyawa dengan sperma) menempel di dinding rahim...ketika ini suhu akan jatuh dan keesokannya akan meningkat semula.

P/S: Tidak semua akan mengalami corpus luteum dip dan implantation dip. Cuma ianya merupakan good sign sahaja. Ada graf yg berjaya hamil tetapi melalui graf tiada ID. Ada juga graf yg TIDAK berjaya tetapi melalui grafnya berlaku ID.

Implantation dip study

Is there such a thing as an implantation dip?

There is a great interest in identifying very early pregnancy signs on charts. Which signs can tell you that you might be pregnant? Which are meaningless? To try to answer this question quantitatively, we have run some statistics on a large sample of charts.
One of the most controversial and puzzling potential signs has always been a luteal phase dip. There has been a lot of speculation about the significance of a temperature dip in the days after ovulation around the time implantation would be expected. We wanted to get to the bottom of the issue and find out once and for all if seeing a dip in the luteal phase, around the time of expected implantation, increased the probability of pregnancy.
Here is what we did:

• We ran a full statistical analysis on 116,691 charts recently processed by Fertility Friend, both pregnancy charts and charts that did not result in pregnancy.
• To be considered as a dip, charts had to show a significant single dip that lasted a single day, occurring between 5 and 12 days past ovulation.

We used a minimum dip size of 0.3F. We also ran the test using several pattern recognition algorithms to validate the correlation independently of the method of measurement.
Here is what we found:

• 11% of charts that showed ovulation but did not result in a pregnancy displayed this pattern.
  
• 23% of charts that showed ovulation and did result in a pregnancy showed this pattern.
  
• Of the pregnancy charts that showed this pattern, the most likely days for the dip to occur were between 7 and 8 days past ovulation.
  

The data suggest that this pattern is indeed more likely to result in a pregnancy.
Remember, though, if you have this pattern, it does not necessarily mean that you are pregnant. It is just increasing your probability.
No matter your chart pattern, you can still be pregnant as long as you have well-timed intercourse within your fertile time. In the end, the only way to really know for sure whether or not you are pregnant is still when you can reliably take a pregnancy test.

What causes an "implantation dip?"

The term implantation dip is often used to refer to a luteal phase dip that occurs around the time of expected implantation (7-10 days past ovulation). While this pattern does not always result in pregnancy, the term is often used because of the timing of the dip and because this pattern appears with greater frequency on pregnancy charts than non-pregnancy charts. There are a couple of factors that may help to explain why this pattern appears with greater frequency on pregnancy charts.

1. The corpus luteum (which produces the heat inducing hormone, progesterone) normally peaks in its production of progesterone and then begins to recede around the middle of the luteal phase. In conception cycles, it is "rescued" when the embryo implants and then continues to produce progesterone until the placenta can take over hormone production.
   
2. Estrogen, in opposition to progesterone, has a lowering effect on temperatures. A secondary estrogen surge in the middle of the luteal phase may cause a temperature dip at this time. Indeed this may explain why this pattern also occurs on non-pregnant charts. Mid-luteal phase estrogen levels, however, have been found to be higher in conception cycles than non-conception cycles and this may also contribute to the greater frequency with which we see this pattern on pregnancy charts.

When you see a mid-luteal phase dip on your chart, however, it does not necessarily mean that you are pregnant. Likewise, you do not have to see this pattern to be pregnant. As long as you have intercourse in your fertile time, you have a chance to be pregnant with any ovulation pattern.
