What Is IVF Therapy?
IVF is short for in-vitro fertilisation. This assisted reproductive technique is used for couples who wish to conceive, but who have experienced difficulties along these lines. When people are strongly considering IVF, they often have questions about the process and the success rate. They also want to know what they need to do to prepare for this type of therapy.
What the Process Basically Involves
The IVF process entails fertilising a woman’s egg outside the body versus the conventional way. Because the man’s sperm and woman’s eggs must come together outside the body, IVF treatment in Singapore involves a process where the egg is retrieved from the woman and sperm from a man, and they are placed into a test tube. This is where fertilisation occurs.
How Long Does a Cycle Last?
When this process is implemented, the cycle lasts only about 12 days. During this span of time, the egg is retrieved from the woman’s body for fertilisation. Selected embryos are frozen before they are delivered back into the woman’s body. The whole process is rather involved, as you will see from the description below.
Stimulation of the Egg
Stimulation of the egg is accomplished by the daily self-administration of hormone injections. This happens from the second day of the menses so that egg maturation is stimulated. An ultrasound scan is used to evaluate egg maturation on the eighth or ninth day, seeing if the eggs can be retrieved.
Egg retrieval is done under anaesthesia to reduce any discomfort. This is done during the day at an IVF medical centre. Retrieved eggs are combined with sperm to be fertilised in the test tube so that the embryos can be cultivated. The embryos are developed until day 5 before certain ones are chosen to be frozen. Afterwards, the chosen embryos are delivered back to the woman’s uterus approximately a month or two later.
The Success Rate for IVF
The woman who is involved in the IVF process undergoes all the steps of the process except for the collection of the sperm. Therefore, this procedure and the cycle involves a total commitment by the female in the relationship. That is why many couples ask about the success rate with respect to the IVF process. Usually, most couples will conceive about 50% of the time.
Freezing Increases Success
By freezing the embryos and placing them back into a woman’s body, doctors find that success rate is enhanced. Researchers believe that embryos that survive the freezing part of the process are more likely to survive. As a result, there is a greater chance that a woman will become pregnant. The transfer of frozen embryos is now routinely practiced by IVF specialists.
The Age of the Woman
The age of the woman receiving the frozen embryos is also considered. While most women who come in for IVF treatments are usually in their late 30s to 40s, younger women also use the process to conceive. A younger woman who has a blocked fallopian tube, for instance, may be interested in conceiving this way.
How Long Does It Usually Take to Get Pregnant?
Usually, three or four IVF cycles are required for success. However, most couples get pregnant after undergoing as few as three cycles.
