Egg retrieval- ideal numbers

Egg retrieval- ideal numbers

For anyone undergoing IVF it is often a painful and stressful process. As well as the constant injections, monitoring of data and visits to the doctors there is always the uncertainty. My friend Nic knows all about this as she is currently undergoing cycle 3 of IVF.
Nic has become something of a Dr Google herself as she researches new findings on IVF and its protocols all the time. Because her end goal of a baby makes it all worthwhile.
I’m something of a study findings junkie myself so I was really pleased when I came across this article yesterday.

Essentially what it says is that after a study involving 400,000 IVF cycles in the UK ‘doctors should aim to retrieve around 15 eggs from a woman’s ovaries in a single cycle in order to have the best chance of achieving a live birth after assisted reproduction technology.’

The study was led by Dr Arri Coomarasamy of Britain’s Birmingham University “A standard stimulation should aim for 10-15 eggs, and we believe this is what is associated with the best IVF outcomes,” Coomarasamy said “When the egg number exceeds 20, the risk of OHSS becomes high.”

OHSS is also known as Ovarian hyperstimulation syndrome caused by hormonal medications that stimulate the development of eggs in a woman’s ovaries. In ovarian hyperstimulation syndrome, the ovaries become swollen and painful and can cause women to suffer pain in the abdomen, swelling and on occasion can also cause nausea and vomiting.

Based on their study Coomarasamy and his team have created a mathematical graph, known as a nomogram. This is designed to show the following
1. the relationship between women’s age,
2. the numbers of eggs retrieved
3. the predicted live birth rate
According to Coomarasamy patients and doctors can use the nomogram, in addition to means, to aid making decisions about the optimum ovarian stimulation needed to get the ideal number of eggs.

With one in seven couples affected by infertility, data and study findings like this are yet another useful link on the information chain for would be parents like my friend Nic.
Will you be telling your doctor about this study?

An interesting study shows the "ideal" number for egg retrieval. Sarah looks at the findings.

I think it is so great you have looked into this especially as it will also help you know & understand what your friend is going through, she will need all the support she & her partner can get. IVF is such an emotion roller coaster, & unless you are going through it or know someone who is, it is hard to understand. I know exactly were she will be at the moment I went through 6 cycles & fell on our 6th attempt. We were blessed with a beautiful little boy 5.5months ago. Our last attempt we had a 3 and a bit month break before trying. Our last cycle they collected 18 eggs we had 2 that made it, Jacob was an 8cell when we implanted & we placed him back in on day 3, we still have one frozen for when we are ready to go again. Other cycles we were geting around 10-13 eggs but only had 1 on one cycle & on another we had 2 placed one fresh & froze the other. I can tell you I was very ready to have those eggs removed, My only wish would be that the government give IVF patient a bit more support, the intial outlay, & now in their great wisdom they have decided to cap everything. Maybe one day when their children need to go through something like this, it will get changed.
You do touch on the 1 in 7 couples, they are also seeing that it is becoming more of a male fertility issue. We were so stunned when there was 27 different ways of doing IVF, no doubt that has changed since we started. They also say that most women impant beter with a fresh cycle, but I don't know we lost a fresh straight up & a frozen took but then we miss carried but in the end it was a fresh so I think it is just meant to be what it will be. Your friend is blessed to have you in her life. My heart goes out to her & while I am not religious, I pray that she is blessed with the one thing she wants so much, BABY. Fingerscrossed.

When researching & going through IVF you are constantly looking for information to give you the edge for a successful treatment. Egg numbers are important but don't get too depressed if your numbers don't match the average cause remember they only need 1 to do the right thing. The numbers vary so much due to so many factors like age, health of you and your ovaries, any pre-existing issues. DH (42) & I (42) been trying for 4+ years, 1 MC@ 9wks, many 6wk+ cycles. 18 months of naturopathy, yoga, acupuncture & healthy living changes to both of us to prepare ourselves for an IVF journey. Jan 2011, I was 42+4 months when I went through IVF ICSI, our first ever cycle, they harvested 3 eggs from only 1 ovary as the other just didn't respond to hormones. 3 embryos via ICSI, 1 very advanced at day 4 & was implanted, the other 2 lagging behind in development & were not deemed viable. With our ages, medical issues, previous illnesses & environmental impacts we were given a 2% success rate. So with that slim chance facing us we didn't think we had a chance, however we are now 19 weeks pregnant, amnio results came back normal & we have a little girl on her way into our hearts & home. Don't give up if your numbers are low, believe in yourselves and the amazing work the IVF doctors & community do.

Congratulations to you both, another success story, Our baby boy was also done by ICSI, & we did the amino but didn't find out the sex until we had him. I am so excited for you both, big changes are on the way. We are now waiting to see the arrival of our friends baby girl due in late July she too was ICSI. OUr nos. were under 1 million, slow mobility. So for all of you out there who are going through or considering IVF don't give up hope as you can see 3 great success stories.
