In Vitro Fertilisation (IVF) is a treatment where eggs are collected from the ovary, fertilised with sperm in a fertility clinic’s laboratory and replaced back into the uterus. On average an IVF cycle will take approximately four weeks.

As your Fertility Specialist I will only recommend IVF if I am sure it will be the most successful treatment for you and only once other less invasive treatments have been considered. The IVF process can often seem quite complex and overwhelming and I will always spend time with you to ensure you have a thorough understanding of what is involved and you feel comfortable proceeding.

IVF is a complex process requiring the input of nurses and scientists. I decided to partner with Monash IVF due to the outstanding care they provide my patients and continually achieving the highest IVF pregnancy success rates in Victoria.

Below is some further information on what happens during an IVF treatment cycle:

Step 1 – Egg Collection

The starting point of the IVF process is obtaining eggs from the ovaries. This is done by administering injections of Follicle Stimulating Hormone which encourages the development of several follicles (the sacs on the ovaries that contain eggs). This process normally takes about ten days. Once enough follicles have developed, the eggs are removed from the ovaries by passing a needle into the fluid filled sacs that contain the eggs (follicles) and aspirating them out. This is a simple day procedure that is performed in theatre under a light anaesthetic.

Step 2 – Sperm Preparation

While the eggs are being collected in theatre, the semen sample is also being prepared. Once collected the semen is added to a test-tube that contains a special media which filters out sperm that have poor motility. If the sperm count is low or if the man has had a surgical sperm collection, the sperm sample will be spun to concentrate as many sperm together as possible. The collected sperm is then used to inseminate the eggs.

Step 3 – Insemination

There are two different types of insemination techniques – IVF standard insemination or Intracytoplasmic Sperm Injection (ICSI). IVF standard insemination is used for patients that have normal sperm sample and involves the scientist in the laboratory placing the eggs and the sperm into a dish and leaving them overnight so that fertilisation can occur. If there are some problems with the sperm sample, or if IVF standard insemination wasn’t successful then ICSI will be used. ICSI involves a scientist injecting a single sperm into each egg.

Step 4 – Fertilisation

The morning after the egg retrieval, the scientists check the eggs for signs of fertilisation. If fertilisation has occurred the fertilised eggs are now called ‘embryos’.

Step 5 – Embryo Culture

Embryos can be grown in the laboratory for up to six days after egg retrieval. They can be replaced back into the uterus at a variety of stages depending on what is right for the patient.

For the majority of my patients I will recommend growing embryos five days after egg retrieval, when the embryo is at the blastocyst stage. Recent research has shown that embryos that can reach the blastocyst stage of development are more likely to be chromosomally balanced compared to 2/3 day (cleavage stage) embryos. Growing embryos to the blastocyst stage enables embryos that are more developmentally competent to be selected which means they have a higher chance of resulting in a pregnancy.

Step 6 – Embryo Transfer

On the day of your embryo transfer, a scientist will assess your embryos and pick the most advanced one for transfer. The embryo will then be loaded into a very soft thin plastic tube and placed back into the uterus. This procedure is very simple and does not require an anaesthetic. The embryos will then continue to grow in the uterus until they implant.

Step 7 – Pregnancy test

Two weeks after your embryo transfer a blood test will occur to determine whether the IVF cycle resulted in a pregnancy.

试管婴儿IVF 是把卵子从卵巢中取出,和精子在生育专科实验室中孕育并放回到子宫内的治疗过程。一般的IVF治疗周期大约是4个星期左右。 作为你的生育专科医生,只有所有其他少侵入性的治疗被考虑后,我才会推荐IVF作为对你最可能的成功的治疗方式来考虑使用。IVF治疗经常看起来相当复杂而且很有压力,我会安排足够时间让你确定你完全理解整个过程并且让你对这个过程感到无压力。 IVF是一个复杂的治疗过程,需要有专科护士和科学家的参与。我决定和莫纳什试管中心合作,主要因为他们对我的病人提供十分全面的护理,并持续在维多利亚州保持最高的怀孕成功率。 下面是IVF 治疗中更具体的一些信息: 第一步 --  取卵 IVF 治疗的初衷是从卵巢中获取卵子。主要是通过注射促卵泡激素来帮助多个卵泡发育(卵巢中的卵泡含有卵子)。这个过程一般有10天时间。一旦有足够的卵泡发育成熟后,达到取卵的要求,就会使用一根细针放入充满液体的卵泡中把卵子吸取出来。这个过程是个简单的日常手术,通过轻微的麻醉在手术室进行。 第二步 --  精子准备 当卵子在手术室被取出,精液样品也在同时准备中。一旦精液样品收集好后被放入含有特别媒体的试管中,这些媒体会把活力差的精子过滤掉。如果精子数量低或是通过手术获得的精子,精液的样品会通过高速旋转的机器萃取来尽量获取高浓度的精液。这些被提纯的精液用来和卵子结合进行受精。 第三步 -- 受精过程 一共有两种受精技术:标准的IVF受精或胞浆内单精子注射(ICSI)。标准IVF受精是用普通的精液样品,然后科学家在实验室里把卵子和精子放入试皿中放置过夜使胚胎形成。如果精液有问题或者标准IVF治疗没有成功,就会使用胞浆内单精子注射ICSI的方式。胞浆内单精子注射ICSI是科学家把单一的精子注射到每一个卵子中的过程。 第四步 -- 胚胎形成 取完卵后的第二天早上,科学家检查卵子是否有形成胚胎的特征。如果卵子孵化发生了, 孵化的卵子被称为“胚胎”。 第五步 --  胚胎培育 取完卵后,胚胎在实验室中发育最多可以达到六天。他们可以在不同的阶段被放回到子宫内,这取决于对病人来说什么是最合适的。 对我的大部分病人,我会推荐取完卵以后让胚胎发育到第五天让胚胎处于胚囊的状态。最近的研究显示当胚胎发育到胚囊的状态的时候比起第二天或者第三天天分裂状态的胚胎是比较有可能达到染色体平衡的。当发育的胚胎到达胚囊的状态比起其他的胚胎更有发育竞争力被选择,这样意味着拥有更高的机会怀孕。 第六步 -- 胚胎植入 当你胚胎植入那天,科学家会评估你的胚胎的情况并选择发育最好的一个进行植入。胚胎会通过放入一个非常细软的管中被放回到子宫。这个过程十分简单,不需要麻醉,胚胎会持续在子宫里继续发育直到其在子宫中着床。 第七步 --   怀孕结果测试 当你的胚胎植入两周后,会做一个抽血测试来判断经IVF的治疗后你是否怀孕。
