Oocyte Freezing – A Friend from Shanghai

Oocyte Freezing – A Friend from Shanghai


Becoming a bride and becoming a mother are two important life events for women. However we cannot predict future. When will we fulfill our dream? When can we meet Mr. Right? Why not embrace the freedom of uncertainty? Oocyte freezing is a good choice for us to free ourselves.

By Dr. Stork Lai



Engagement is a promise to get married. Oocyte freezing is insurance for having a baby in the future. Becoming a bride and becoming a mother are two important life events for women. To whom will you reach out your hand for such important events?

We have a lot of clients from oversea. Clients from Mainland China are lesser. But it’s increasing these two years. Most of them are “high difficulty” cases. For example, primary ovarian insufficiency, habitual abortion, genetic disease and fail for a lot of times. However, there was no one from Mainland China came for oocyte freezing program. And she became the first one.

I met her last March. She came with her friend. They met each other when they studied in Europe. This Taiwanese friend froze her eggs few months earlier, because she had goals to reach at the time. After freezing, her future seems to be full of hope, which made her felt great and wanted to share with her friend and leaded to our first oocyte freezing client from Mainland China.

It’s easier when you have a friend accompany with you. After first consultation, she brought back all the injections needed in the program. I designed the simplest stimulated protocol for her. Which not only can minimize the time she came to Taiwan but also retrieve more oocytes. Moreover, in order to avoid ovarian hyper stimulation syndrome, I choose to use GnRHa as trigger injection.

We met for the second time on the ninth day of her period. She came for ultrasound and blood test and get total 19 follicles. Two of them are large, six in medium size. The others are small ones. Because the growing speed of the follicles were faster than expected, we do oocyte retrieval two days earlier than my original plan. We got 22 oocytes in total. Exclude one bad quality oocyte and two immature ones, 19 mature oocytes were frozen.

Life is full of uncertainty. When will we fulfill our dream? When can we meet Mr. Right? Why not embrace the freedom of uncertainty? And try to do what you can do for your future self. She only came to Taiwan two times and stay for about a week. Except came for following check up shortly, she was traveling Taiwan for most of her time. Experience beauty of nature and exotic culture.

Can oocyte freezing bring blessing and good luck? I received a box of delicate wedding cake a few days before. The familiar name printed on the card surprised me. She studied in America and had a great job after graduate. However, she hadn't get married. And came for oocyte freezing around 40 years old. And after two years, she finally met the one she wanted to walk down the aisle with. She is the first one who get married after oocyte freezing. I'm so happy for her.
    
Before oocyte freezing, there are three questions I will ask. "Do you have a boyfriend that you are considering marry him?","Will you get married within 2 to 3 years?", "How many children do you want after you get married?". I've ask her before. Although the answer was no, she finally found the one, which makes me very happy.

I don't know if oocyte freezing can bring good luck or not. But I am sure it can brings you confidence and relief. When you are confident and relieved, good thing will happen to you very often. The most beautiful woman is one who is confident about herself. When you can show your own beauty, you have great possibility to meet the right one. Hope the clients who froze their hope here can find their true love as soon as possible and enjoy a warm family with children.

The Depressing “8 accidents” of IVF Treatment




What is the most depressing part of IVF? For younger women with abundant ovarian reserve, the process would be smoother. Usually, 1-2 times oocyte retrievals are highly possible to create a baby. However, for women over age 38, there might be numerous obstacles.

Age> 38 and AMH< 2 are 2 indicators of “Diminished ovarian reserve”. 
The following situations are “8 accidents” we concluded from our previous experience.

Bad response
For example: We saw 5 small follicles on D1-3 of the patients’ period. However, the number of follicles decrease after stimulation. The primary reason of this situation is the bad quality of follicles which are not able to proceed developing.
Earlier ovulation
The ovulation should occur at 36-40 hr after trigger. However, if the ovulation occur earlier then we expect, we might not be able to extract the oocytes when operation performing.
Empty follicle
Usually, there would be an oocyte inside a follicle. However, in some cases, there might be no oocyte in the follicle, which we called a “empty follicle”.
Low good oocytes rate
The good oocytes rate for women under age 35 is over 70%. For women over age 40, the good oocytes rate is lower than 50%. Even worse, some of the oocytes might be defective for insemination.
Low fertilization rate
The overall fertilization rate is about 70%. However, for some cases, the fertilization might be lower than we expect.
Abnormal fertilization
The fertilization might turn out to be 3PN or other abnormality.
Not dividing
95% of the fertilized eggs would go on cell division. However, some of them might not undergo cell division.
Stop developing
The normal embryos will divide in 15-17 hours. The embryo should acquire 6-8 cells after 3-day culture. However, the embryo might stop developing during the culture, which will end up no embryo for further transfer or freezing.

How to prevent these 8 accidents?
Bad response
Planning the PP-IVF (Personal Precision IVF), such as mild stimulation, natural cycle or D-OPU.
Earlier ovulation
The time point of trigger is different depends on the age. For women under age 40, we only trigger when the follicles are bigger than 17 mm. For women age under 40, we would adjust the trigger at 15-17 mm follicles size. Since the follicles walls of older women are less flexible (might rupture when the size is 20 mm), we can use the prostate gland inhibitor (anal suppositories) to prevent the rupture at 8-14 hrs prior to the oocyte retrieval.
Empty follicle
There might be truly no oocytes in the follicles. Otherwise, the time point and the method of trigger might also the reasons of empty follicles. In this case, we can try adjusting the time or the gesture of the trigger.
Low good oocytes rate
The oocytes would be observed by embryologist after the operation. Those defective oocytes are neither predictable nor not able to undergo fertilization. What we can do is to keep collecting more oocytes with good quality.
Low fertilization rate
The low fertilization rate is related to the quality of sperm and oocyte. The quality of the oocytes is depending on the age, when is unalterable. What we can try is using microscopy with higher resolution (6300X IMSI) to choose sperms with better quality.
Abnormal fertilization
Usually, for those who have fewer oocytes, ICSI is used as the first priority method of fertilization. The cause of this situation are mostly the chromosomal abnormality of the oocytes. What we can do is to keep collecting more oocytes with good quality.
Not developing
The cause of this situation is more related to the quality of the oocyte. What we can do is to keep collecting more oocytes with good quality.
Stop developing
From the genetic aspect, the better embryos have higher possibility to keep developing. The abnormal embryos would be naturally eliminated and often stop developing at D3-4 of the culture. What we can do is to keep collecting more embryos with good quality.

Under which circumstances should I consider using oocytes from younger donor?
According to our statics, for women at age 43, it might take 120 oocytes to successfully bring back a baby. The live birth rate each oocyte retrieval and transfer is only 3.5%. Under these conditions, do you still have the courage to keep going? If the answer is uncertain, maybe you can start considering the oocytes recipient program. 
We suggest women with the following conditions to consider using oocytes from the donor:
1.      Women older than 43 years old.
2.      Continuously getting empty follicles for 3 times oocytes retrievals.
3.      Continuously getting 0 oocytes for 3 times oocytes retrievals.
4.      Continuously having 0 embryos for further transfer for 3 times.

Sperm Donation Program

Sperm Donation Program


Some males might suffer from infertility due to some diseases such as congenital chromosomal abnormalities and endocrine system abnormalities. Or testicular dysfunction, varicocele, sperm transportation dysfunction. etc. Or due to living habits, working environment, physical and mental illnesses and other factors such as drugs, radiation and sexual transmitted diseases, etc.
For these reasons, couples might need to borrow sperm form others to achieve their dream of having a complete family. 
Stork Fertility Centre has our own Sperm Bank, donors went through strict examinations and health assessments. As we have our bank, the waiting time for a suitable donor will be reduced to around 1 month after handing in all the required paper works. 

FQA
· What health assessment did the donor have?
the donor will go through assessment including infectious diseases such as hepatitis B, hepatitis C, syphilis, gonorrhea and AIDS; Tests for genetic diseases such as thalassemia (complete blood count, CBC) and spinal muscular atrophy (genetic testing), karyotype testing, and Fragile X gene screening, etc. 

· Is it good to use thawed sperm? 
The donor's sperm preserve by the slow freezing method mixed with the cryoprotectant and gradually cooled down to -196 C. The survival rate after thawing is about 30-50%.
Preservation of sperm in extremely low-temperature liquid nitrogen equals freezing time, and storage for more than ten years is not a problem.

· How many times can we use the sperm?
It depends on what treatments you are undergoing. 
In Vitro Fertilization: approximately 3-4 times using Intracytoplasmic Sperm Injection, ICSI
Intrauterine insemination: approximately 1-2 times

· Can we see donor's photos?
No. Medical care institutions shall provide information concerning the donor's ethnicity, skin color, and blood type for the reference of the recipient couple only. We can not revive personal information about the donor due to the law restriction. 

· Can I choose a specific donor? 
According to Taiwan's Assisted Reproduction Act, "A medical care institution performing assisted reproduction shall not use a specific donor’s reproductive cells as requested by the recipient couple; a medical care institution shall not use donated reproductive cells for a specific recipient couple as requested by the donor.

· Do you have caucasian donors? 
No, all our donors are Taiwanese(Asian).
