Insemination (IUI) and in vitro fertilization (IVF) are the two most commonly used fertility treatments. These two techniques have been in practice for decades. Still, people are often confused and unable to distinguish between the two medical terms.
Both IVF and IUI are used to help couples struggling to get pregnant naturally.
– In IUI, sperm are placed directly in the uterus using a microscope.
– In IVF, the egg is surgically removed and sperm fertilize on a dish in a laboratory-assisted environment. The fertilized egg is then transferred to the uterus.
Let’s understand both techniques in detail.
What is IUI?
IUI or insemination is a fertility treatment in which sperm are placed directly in the uterus. IUI fertility treatment allows higher concentrations of healthy sperm to come closer to the egg, increasing the chances of conception.
At the beginning of IUI treatment, women receive injections and medications to stimulate the body to lay more eggs than normal. Once the dosing course begins, fertility specialists will closely check egg production and regularly monitor your health through ultrasound and blood tests. The specialist will schedule your insemination treatment to match your ovulation.
Meanwhile, the specialist prepares the sperm for treatment. In the process, you can use fresh sperm from your partner or sperm from your donor. Sperm are washed and prepared before being transplanted into the uterus. Chemicals that can increase fertility are used to separate sperm from semen and wash them.
After separation and cleaning, specialists place sperm into a thin catheter and insert it into the vagina. Women are required to lie on their backs with their legs wide open. Using a microscope, the doctor opens the cervix and uses a soft, flexible catheter to gently transplant the sperm into the uterus.
What are the different forms of IUI?
There are four different types of IUI cycles, depending on the drug used. Depending on your choice, medical history and fertility test, an IUI specialist will determine the best treatment for you. The types of IUI are:
– Natural cycle – In the natural IUI cycle, no drugs are used to produce eggs.
– Trigger cycle – With a trigger cycle, the drug triggers successful ovulation for a period of time, increasing the chances of getting pregnant. The IUI process starts 12 to 36 hours after the trigger cycle.
– Oral medication cycle – In this cycle, oral medications are given to promote egg development and ovulation.
.- Injectable Dosing Cycle- Gonadotropin drugs are injected into the ovaries along with oral drugs.
What is IVF?
IVF is yet another common fertility treatment. Like IUI, IVF treatment begins with medications and injections that are given to stimulate the ovaries and increase the number of eggs. Development is monitored through blood tests and ultrasound.
When the egg matures, fertility specialists collect the egg. In the “egg collection” process, a specialist inserts a thin needle into the vagina to remove the egg. In the process, the patient is sedated with general anesthesia. There may be some nasty feelings about the absence of such major complications and discomfort.
Take out the eggs and place them on a plate. On the other side, a specialist prepares sperm. Sperm can be obtained from either a partner or a donor. The sperm used is either fresh sperm or frozen sperm. The sperm are washed, all dirt and debris removed, and the eggs on the plate are fertilized.
If the cause of infertility is due to a serious problem with a male partner, use a needle to inject healthy sperm into the egg. This process is known as intracytoplasmic sperm injection or ICSI. This is an advanced treatment for in vitro fertilization.
Once the egg is fertilized, the embryo is carefully monitored for the next 5-6 days. The embryo is then transferred to the uterus. Like IUI, women can sleep on their backs with their legs wide open. Using a very soft and flexible catheter, specialists transplant the embryo into the uterus. The woman is asked to stay in that position for the next few minutes so that the embryo can be successfully planted.
The type of in vitro fertilization is based on drug use, fertilization, and embryonic processing. The types of in vitro fertilization are:
– Traditional IVF – This is the normal IVF process in which an egg and sperm are fertilized in a Petri dish.
– ICSI – An advanced form of in vitro fertilization in which sperm are injected into an egg with a microneedle.
– Mini IVF – The process of producing lower quality eggs with minimal medication.
– Natural IVF – No drugs are used to stimulate the ovaries. Only one egg is collected in this process, and in rare cases two eggs are collected.
FET IVF – Not fresh, but frozen and thawed embryos are transferred to the uterus.

|monitoring||Needs monitoring only for powerful drugs||Always need monitoring|
|Surgery||No surgery||Surgery is required during egg collection|
|Where is fertilization done?||Directly on the woman’s body||Infertility laboratory|
|Possibility of multiple pregnancies||number||If multiple embryos develop, they can be frozen and transplanted for multiple pregnancies|
|Donor egg options||number||Yes|
|Donor sperm options||Yes||Yes|
Which fertility treatment is correct, IUI or IVF?
There is no rule that one of the two treatments is better than the other. IUI may be effective for some women, but IVF may be more effective for others.
IUI is cheaper and less invasive than IVF. IUI is often recommended for couples with mild infertility and unexplained infertility. Recommended for women over 40 years old. IVF is recommended for couples with severe infertility disorders, women facing multiple miscarriages, or women with blocked fallopian tubes. In any case, IUI and IVF have been proven to benefit millions of couples and make their pregnancy successful.
Important Facts About IUI and IVF:
– With IUI treatment, women lay only one or two eggs.
– Sperm deposit directly in the uterus, but there is no guarantee that fertilization will be successful.
– Drugs given with IVF are usually much more powerful than drugs given with IUI.
– With the help of medicine, a woman can lay 15-18 mature eggs.
How safe are IUI and IVF?
– Both IUI and IVF are safe pregnancy treatments. Both processes are unlikely to cause significant complications.
– Close monitoring of dosage and development can reduce the likelihood of complications in both IUI and IVF.
– IUI does not require any form of surgery. IVF requires surgery during “egg collection” under the influence of anesthesia.
Every patient and every pregnancy is different. Therefore, assess your health and find out which process is best for you. You should consult with an experienced fertility specialist to discuss recommended behavioral policies.
