Artificial Insemination (IUI) is a simple and painless Assisted Reproduction Technique that consists of introducing a semen sample into the patient’s uterus when she is ovulating.
The expert in fertility inserts an ultrasound-guided cannula through the vagina to deposit the sample. The eggs are not retrieved to be fertilised.
The sperm sample can be from the patient’s partner or from an anonymous donor. To increase the chances of achieving pregnancy, we select the sperm with the best prognosis. Then, we perform a mild ovarian stimulation controlled by ultrasound to help us know when is the best moment to perform the insemination.
With the Artificial Insemination, the fertilisation occurs naturally in the woman’s body (compared to IVF).

Success Rates of an Artificial Insemination in Spain
- With seprm of your partner: 25%
- With seprm of a donor: 45%
Who is the Artificial Insemination indicated for?
This technique is recommended for:
- Young patients, recommended before 38 years of age.
- Normal ovarian reserve.
- Permeable fallopian tubes, that is, not obstructed.
- Good quality of the partner’s semen.
- Single mothers by choice
Artificial insemination only slightly increases the chances of fertilisation compared with sexual intercourse, so it is not indicated for all patients. For this reason, your fertility specialist should give you a personal assessment and a full diagnosis, and help you choose the treatment best suited to your case.

How are sperm donors for an Artificial Insemination selected in Spain
In Spain, Assisted Reproduction Treatments for single women has been authorised by law for many years and this gives us a large experience with this treatment.
An important aspect of this treatment is the anonymity of the donors. The law guarantees the secrecy of the identity of men who decide to donate their gametes so that our patients can have their baby.
The other key aspect of the donor selection is the physical resemblance with the future mother. The medical team will match your phenotype with the donor’s to find the right one for you.
Step-by-step process of an IUI in Spain
The first consultation is carried on online or at the clinic, depending on your availability. The Docteur will study your medical history, assess your case and establish a personalised treatment plan. Your personal assistant will then send/give you all the documents you need to make your decision and start your treatment from home.

Artificial insemination is performed following your natural cycle or through a small hormonal stimulation to help follicular development. This treatment is very simple and consists of subcutaneous injections, which you can easily self-administer at home for a period of approximately 10-14 days. Throughout the stimulation, the growth and development of the follicles is monitored by ultrasound to identify the ideal time to perform the insemination.
When the dominant follicle has reached an adequate size, we provoke ovulation by a final injection of hCG hormone.
The day of insemination coincides with the woman’s ovulation, to facilitate the encounter between egg and sperm. On this day, we prepare the semen sample (from the couple or from a donor, depending on each case) and we insert it into the uterus through the vagina by means of a cannula containing said sample. The procedure is very simple and does not require anesthesia or painkillers. For patients who do not live in Spain, a stay in our country of no more than 2 – 3 days is required.
After the insemination, you can resume a normal life, without having to rest. You will know the result of the treatment after about two weeks of waiting. At this time, you can take a pregnancy test.

Real experiences from Vida Fertility’s patients

It is incredible how, from absolute resignation, these doctors have lifted my spirits. They got me pregnant and gave me my life back. They live up to their name.

I had to find a way to become a mother if I wanted to pursue my career and not settle for just any partner. I made the right choice.

From the very first moment I felt I was being listened to, understood, and above all, I felt that my treatment was finally going in the right direction.

Hello dear Mrs Ortega,
you and the whole team of Vida fertility make us so happy. Finally a relief that we can be helped! Many thanks to you and all the others for the great care and exceptional quality work. This high quality means a lot to us. We hope that in 2024 we can take a healthy baby full of love into our arms.❤️

Thanks to Dr. Kathi’s support and by following all her advice, the best moment of the treatment came: I got pregnant.

I didn’t know if I would ever be able to get pregnant and now I’m in my 5th month of pregnancy.

It hasn’t been an easy journey. After the second attempt, I am happy to say that in two months I will be meeting my little girl.

Being able to experience this shared motherhood has been a gift for the two of us.
THANK YOU to this great team for everything!

We highly recommend Vida Fertility to anyone who has already given up hope and wants to give it one last try.

A huge thank you to the entire Vida Fertility team, especially to Sophie and Dr. Spies, who helped us achieve the wonderful project of expanding our family. We met a very competent team who perfectly guided and advised us on the medical choices to make at each stage of our journey. 🫶

I recommend Vida Fertility for their professionalism, humanism, and availability.
Our wonderful baby is the proof that the results are there!
Thank you!

Thanks to Vida fertility, we are now mums. Mums!!
It’s the greatest gift of all, we’re so happy!

The good feeling will certainly have contributed to the success of the treatment.
When we first contacted the clinic, I didn’t expect to become a mum so quickly, and now I even have hope that we might be able to create a sibling for our son with the remaining blastocysts.
Thank you!

I chose Vida Fertility because it’s a clinic that offers human support from the very beginning. I’m convinced that my state of mind, so influenced by the unconditional support they gave me, was key to the success of my treatment.

At the first consultation, I felt heard, understood, and full of hope again. The final transfer, our last chance, took place in February 2024… and it worked. Our little girl has brought immense joy to our whole family.

Being a single parent brings challenges, but I’d recommend anyone thinking about it to go for it. Vida Fertility made my dream come true with my first IVF.
FAQ about Artificial Insemination in Spain
The cost of artificial insemination or IUI can be one of the cheapest assisted reproduction treatments. However, each patient is unique and you need to consult a fertility specialist who will evaluate, advise you and accompany you in creating the most appropriate treatment for you. In addition, as there are two types of artificial insemination – with partner sperm or with a donor sperm – the price of an IUI may vary. We invite you to set up a first appointment with our team at one of the Vida Fertility clinics in Madrid or Alicante to get your personal medical assessment and quotation.
The artificial insemination process generally takes between 2 and 3 weeks, from monitoring the woman’s natural or induced cycle to insemination.
This period may vary according to the individual characteristics of each patient.
Before undergoing artificial insemination treatment, a number of tests are carried out, including hormone analysis, ultrasound scans to assess the uterus and ovaries, and sperm analysis if you are using your partner’s sperm.
Artificial insemination is generally a painless procedure. Some women may feel a slight discomfort similar to that of a pelvic examination, but it is not considered painful.
At Vida Fertility, we believe that consistency and trust are key to getting the best results. That’s why your treatment will always be monitored by the same doctor, from your first visit to the end of the first trimester of your pregnancy.
Your specialist will have a full understanding of your history, your tests results and every detail of your treatment, allowing us to offer you fully personalised and comprehensive medical care.
Only in exceptional cases – for circumstances beyond the clinic’s control – might another member of the medical team attend to you, always with the same professionalism and under the supervision of your regular doctor.
At Vida Fertility, you can do an IUI in both our centres from Madrid and Alicante.
Sperm donors at Vida Fertility are selected through sperm banks regulated by strict medical and legal criteria, guaranteeing anonymity and quality of the samples.
All donors undergo an exhaustive selection process that includes genetic and psychological tests.
