In vitro versus insemination - what's the difference? .
Insemination and IVF belong to assisted reproductive techniques, often colloquially referred to as „artificial insemination”. In reality, they differ in their course and indications. We bring you up to date on what insemination is, what IVF is and in which situations a doctor recommends each of these methods.
Insemination - what does it involve and what does it mean?
Intrauterine insemination is the least burdensome method of insemination. A procedure in which suitably prepared semen, from a partner or donor, is inserted directly into the woman's uterine cavity.
Before administration, the sperm is carefully selected. Sperm with normal motility and proper morphology, i.e. normal structure, are selected. The administration of the semen is carried out using a thin catheter, making the procedure quick, painless and minimally invasive. The entire procedure takes only a few minutes.
After the insemination, the patient rests for a few minutes, after which she can return to her normal activities. She can drive, work or do light physical activity. There is no requirement to remain in a reclining position or to restrict daily activities.
In vitro fertilisation (IVF) - what is in vitro fertilisation?
In vitro, is a method of infertility treatment in which fertilisation takes place outside the woman's body. The doctor takes egg cells from the woman, which are then combined with sperm cells in the laboratory. After a few days, the resulting embryos are transferred into the uterine cavity (performing a so-called transfer).
Insemination vs in vitro - key differences
Both insemination and IVF are methods of assisted reproduction that are often referred to as artificial insemination, but they differ significantly in terms of their course and indications.
Insemination versus in vitro - key differences:
Place of fertilisation
In the case of insemination, fertilisation takes place naturally, inside the woman's body. The sperm is administered into the uterine cavity and continues on its own to reach the egg cell.
With the in vitro method, on the other hand, fertilisation takes place outside the body, under laboratory conditions - after the egg cells have been retrieved and combined with sperm.
Invasiveness
Insemination is a minimally invasive and painless procedure, requiring no anaesthesia or hospital stay. The entire procedure takes a few minutes and allows the patient to quickly return to daily activities.
In contrast, IVF is more invasive - involving hormonal stimulation of the ovaries, puncture to retrieve the ova and transfer of embryos into the uterine cavity. Some stages require anaesthesia.
Complexity of the procedure
Insemination is a relatively simple and quick procedure, often performed in an outpatient setting. The procedure is performed as part of the patient's natural or gently stimulated menstrual cycle.
The IVF process is a multi-step process - including hormonal stimulation, cycle monitoring, ovarian puncture, cell fertilisation and embryo transfer, as well as possible embryo freezing.
Effectiveness
The success rate of insemination is lower and largely depends on individual factors such as the woman's age, the quality of the sperm and the cause of infertility.
IVF, on the other hand, has a higher success rate, especially in couples with more serious medical problems, such as fallopian tube obstruction, severe male factor or advanced endometriosis.
Who is insemination for? Indications for the procedure
Intrauterine insemination (IUI) is one of the less invasive and more accessible methods of assisted reproduction. It is often recommended to couples in whom male factor infertility is mild in nature or its cause has not been established.
Here are the most common indications for insemination:
Mild abnormalities of semen parameters
Insemination can be effective when the number, motility or morphology of the sperm is slightly reduced, but still allows fertilisation. With proper semen preparation in the laboratory, it is possible to „select” the best sperm and increase the chances of fertilisation.
Idiopathic infertility (of unknown cause)
When the cause of infertility cannot be found despite thorough investigations, we speak of idiopathic infertility. In such situations, insemination is often the first step in treatment, as it can increase the chances of getting pregnant without having to resort to more advanced methods.
Ovulation disorders
In women with irregular or infrequent ovulation, insemination is often combined with ovulation induction with hormonal medication. In this way, the timing of sperm administration can be precisely planned and the chances of conception can be increased.
Cervical factor
If the cervical mucus is abnormal or contains antisperm antibodies that impede the migration of sperm into the fallopian tubes, insemination allows them to be „bypassed” by administering sperm directly into the uterine cavity.
For insemination to be meaningful, at least one fallopian tube must be unobstructed. The patency of the fallopian tubes can be assessed by HSG (hysterosalpingography) or sono-HSG (ultrasound patency assessment), among other methods. If both fallopian tubes are obstructed, insemination will not be successful - other methods such as in vitro fertilisation are then considered.
When does a doctor qualify a couple for IVF?
In vitro fertilisation (in vitro fertilisation, IVF) is one of the most advanced treatments for infertility. A doctor qualifies a couple for this procedure usually when other methods - including insemination - prove ineffective or when there are specific medical indications.
When is the in vitro method used?
Obstruction or absence of fallopian tubes
If a woman has been diagnosed with obstruction of both fallopian tubes or if they have been surgically removed, fertilisation by natural means or by insemination is impossible. In such a situation, IVF becomes the only effective treatment for infertility.
Advanced endometriosis
In cases endometriosis A stage III or IV pregnancy results in significant anatomical changes within the pelvis, which make fertilisation and embryo implantation difficult. IVF makes it possible to „bypass” unfavourable conditions in the abdominal cavity and increases the chance of pregnancy.
Heavy male factor
In the case of poor sperm parameters, such as a very low sperm count, lack of motile sperm or abnormal cell structure, insemination often proves unsuccessful. In such situations, doctors usually recommend IVF treatment, which offers a better chance of fertilisation.
Low ovarian reserve and advanced female age
In women with reduced ovarian reserve (e.g. low AMH, low number of antral follicles) or in women over the age of 35, time plays a crucial role. In such cases, doctors often recommend IVF, as this maximises the use of available ova and increases the chances of pregnancy.
Need for preimplantation diagnosis (PGT)
If there is a risk of transmitting a genetic disease to the offspring (e.g. carrying a mutation), the doctor may recommend IVF with preimplantation diagnosis (PGT). With this method, it is possible to test the embryos before transfer and select those free of the mutation in question.
Which method should you choose? Trust the knowledge and experience of your doctor
The choice of the appropriate method of infertility treatment, such as insemination, IVF or another form of support, should always be based on a thorough diagnosis and an individual assessment of the situation of both partners. The specialist doctor, analysing the test results and medical history, chooses the most appropriate treatment method, choosing between insemination and IVF, taking into account the woman's age, the quality of the sperm, how long she has been trying for a child and other health factors.
Insemination can be seen as an initial step on the path of therapy before more complex procedures, such as IVF, are necessary.
