Thirty-eight years old and feeling empty after three failed IVF attempts in France. Marie remembers that day down to the smallest detail. Outside the window, Paris bustled with its usual hustle and bustle, while inside their apartment there was a deafening silence. Beside her was Jean, her forty-year-old husband, holding her hand. They had tried every available method at the best medical facilities in the French capital. The result remained the same, and with each new treatment protocol, their strength dwindled further.
The problem lay in her critically low levels of anti-Müllerian hormone. Marie’s ovarian reserve had been depleted long before they began planning a family. French specialists could do nothing but shrug, as the chances of obtaining mature, high-quality eggs from her own body were virtually zero. Hormonal fluctuations, the agonizing wait for a call from the lab, and tears over negative hCG test results became their daily reality for several years.
They had to either accept their situation or seek a completely different path. They chose the latter.
First Online Consultation with the Doctor
NatuVitro Reproductive Medicine Clinic came to their attention thanks to international reviews and recommendations from couples with similar medical histories. The first consultation took place via remote video call. The doctor appeared on the screen.
The doctor carefully reviewed the medical records from France, the graphs showing the decline in AMH levels, and the stimulation protocols. He made no empty promises. The conversation was extremely candid yet sensitive. The doctor explained right away that continuing stimulation with their own oocytes would only waste time and emotional resources, and that the most reliable and physiologically sound path to having a healthy child in their situation was through an IVF program with egg donation.
In Spain, this process is strictly regulated. The doctor explained all the legal requirements in detail: the law protects the complete anonymity of the donation, so the intended parents and the donor will never learn each other’s personal information. All candidates must undergo a multi-stage screening process, including comprehensive genetic panels, karyotyping, tests for hidden mutations, and an in-depth psychological evaluation. Upon hearing these clear medical arguments, Marie and Jean breathed a sigh of relief for the first time in many months. They now had a clear plan of action.
Preparation and Coordination Across Cities
The couple did not need to stay in another country for months. The clinic organized the logistics so that patients would be disrupted as little as possible from their usual work schedules. Marie and Jean continued to live in Paris.
The doctor developed a personalized program of gentle hormonal preparation of the endometrium. Every step was monitored remotely. French gynecologists performed scheduled ultrasounds to measure the thickness of the endometrial lining, took follow-up blood tests for estradiol and progesterone, and promptly forwarded the results to Spain. The doctor analyzed the progress in real time and adjusted the medication dosages. The coordinated efforts of the French and Spanish teams made it possible to completely avoid any organizational stress.
Donor Selection Based on Strict Standards
While Marie’s body was preparing to receive the embryo, NatuVitro coordinators searched for the ideal donor. The criteria for phenotypic compatibility were followed with the utmost precision.
The specialists took Marie’s European phenotype into account:
- skin tone and natural hair texture;
- height and body type;
- eye shape and color;
- blood type and Rh factor.
The selected female donor was young, physically healthy, and had successfully undergone comprehensive genetic screening for monogenic hereditary diseases. Throughout the entire preparation period, the doctor stayed in regular contact, keeping the couple informed about every step and alleviating even the slightest concerns of the expectant parents.
The Laboratory Phase and the Embryologists’ Work
The day of the donor’s egg retrieval arrived. The egg retrieval procedure took place in the operating room of the clinic in Spain under full anesthetic supervision. The retrieved mature oocytes of the highest quality were immediately transferred to the embryology laboratory.
On the same day, Jean’s sperm was prepared for fertilization using the ICSI method. The embryologist manually selected the morphologically soundest and most active sperm for each oocyte and injected it directly into the cell’s cytoplasm using a micro-needle. This method eliminated any chance of error and guaranteed the highest possible rate of successful fertilization.
Then came the days of waiting. The resulting embryos were cultured in next-generation multi-gas incubators. A continuous monitoring camera tracked cell division around the clock without disrupting the microclimate of the environment. The embryos successfully passed through the critical cleavage phases and safely reached the blastocyst stage on the fifth day. This indicated their high viability and genetic integrity.
The Long-Awaited Transfer and Two Lines
When the blastocyst was ready and Marie’s endometrium had reached optimal structure and receptivity, the couple flew to Spain. The trip took only a few days.
The doctor personally performed the embryo transfer. The procedure took just a few minutes, was completely painless, and was conducted under continuous ultrasound monitoring. Marie stayed in a comfortable day-care ward for about another hour, holding her husband’s hand, after which they were able to go for a leisurely walk, and the next day they flew back to Paris.
Two weeks later, the morning of the follow-up blood test arrived. A call from the lab reached Marie at home. The beta-hCG level showed a clear and high result: pregnancy had been achieved on the first embryo transfer attempt. After years of pain and disappointment, the realization set in that a new life was taking shape inside her.
The first ultrasound scan confirmed that the embryo was properly implanted in the uterine cavity. At the next ultrasound, Marie and Jean heard the rhythmic beating of the tiny heart for the first time.
Support Throughout the First Trimester
After the positive test, contact with the clinic continued. The doctor continued to monitor the patient remotely, gradually reducing the dosage of maintenance therapy as the placenta matured. Coordinators remained available around the clock for consultations regarding her well-being. The Parisian obstetrician managed the pregnancy in strict accordance with the recommendations of his Spanish colleagues, which gave the couple complete peace of mind and confidence in a successful outcome.
The journey from the first video call to a steadily progressing pregnancy took about half a year. This clinical case demonstrated that competent cross-border medical care, the professionalism of embryologists, and a sensitive, individualized approach can overcome even the most challenging reproductive history.
Questions and Answers
Why do donor oocytes offer the best chance when AMH levels are low?
Anti-Müllerian hormone reflects the number of follicles remaining in the ovaries. When AMH levels drop significantly, stimulation often results in empty follicles or oocytes with chromosomal abnormalities that are unable to develop into a healthy embryo. Donor eggs from young, medically screened women possess the greatest genetic potential, which increases the likelihood of a clinical pregnancy to seventy percent per embryo transfer.
How Spain’s Donor Anonymity Law Works
Spanish law strictly protects donor anonymity in the interests of both parties. The donor’s personal information is not disclosed to recipients, and the donor herself never receives information about the family or the child born. Matching is conducted exclusively by doctors and clinic coordinators based on maximum physical resemblance, eye color, hair texture, height, and blood type.
How many days do you need to spend in Spain to complete the program?
Patients undergo most of the examinations and hormonal preparation at home under a doctor’s remote supervision. You need to travel to Spain only once for a period of three to five days. This time is sufficient for the husband to provide a semen sample, for the embryos to be cultured, and for the carefully monitored transfer of the resulting embryo into the uterine cavity.
How does ICSI differ from conventional IVF?
In the conventional IVF protocol, sperm are placed in a single dish with the egg and penetrate it on their own. With the ICSI method, a specialist in the embryology laboratory selects a single, morphologically perfect sperm and, using a micro-needle, injects it directly into the oocyte’s cytoplasm. This guarantees reliable fertilization even when semen quality is compromised.
How long do embryos develop before implantation?
The clinic’s embryologists culture the embryos until the blastocyst stage, which occurs on the fifth or sixth day of culture. Only the strongest embryos with a normal karyotype reach this stage. Transfer on the fifth day most closely mimics the natural physiology of the female body, since during natural conception, the fertilized egg enters the uterus at exactly this same time.
