The different treatments available in assisted reproduction can raise questions, especially when several therapeutic options are available. One of the most frequently asked questions is what the difference is between artificial insemination and in vitro fertilisation (IVF), and when each one is recommended.
Although both techniques aim to achieve a pregnancy, there are important differences in their procedure, complexity, indications and chances of success.
How is each treatment performed?
Artificial insemination consists of placing a semen sample that has been previously prepared in the laboratory into the uterus, coinciding with the time of ovulation. In this case, fertilisation occurs naturally inside the woman's body.
In IVF, by contrast, the egg is fertilised by the sperm in the laboratory and, subsequently, the embryo is then transferred to the uterus.
Main differences between Artificial Insemination and In Vitro Fertilisation
In addition to where fertilisation takes place, there are other important differences between the two treatments.
Treatment complexity
Artificial insemination:
- Is a more straightforward procedure.
- Does not require egg retrieval.
- Involves less medical intervention.
IVF:
- Requires ovarian stimulation.
- Egg retrieval is performed through follicular puncture.
- Requires monitoring and assessment of embryo development in the laboratory.
Number of attempts
Artificial insemination can be performed in consecutive cycles if the specialist considers it appropriate.
In the case of IVF, the interval between treatments depends on factors such as ovarian response and each patient's individual characteristics.
There is no established maximum number of treatment attempts, so each case must be reassessed individually after each cycle.
Success rates
The chances of treatment success depend on multiple factors, especially:
- The woman's age.
- Her ovarian reserve.
- The quality of the embryos.
- The cause of infertility.
In general terms, artificial insemination usually has lower pregnancy rates per cycle than IVF.
Associated risks
Assisted reproduction treatments are becoming increasingly safe thanks to personalised treatment protocols and close medical monitoring. Even so, as with any medical procedure, there may be associated risks.
Risks associated with artificial insemination:
- Multiple pregnancy, related to ovarian response during stimulation.
Risks associated with IVF:
- Ovarian hyperstimulation syndrome, increasingly less frequent thanks to the use of personalised protocols.
- Bleeding associated with ovarian puncture.
- Multiple pregnancy, a risk that has been significantly reduced through single embryo transfer.
Which treatment is better?
There is no single best treatment, but rather the most appropriate technique for each situation.
The choice depends on factors such as:
- Age
- Reproductive diagnosis
- Ovarian reserve
- Male factor
At Barcelona IVF , each case is studied individually to recommend the most appropriate treatment and provide clear information and support throughout the process.
