Being a single mother is no longer a pipe dream: today it is a courageous decision, increasingly common and supported by reproductive medicine.. The artificial insemination with donor semen It has become the simplest and most affordable gateway for those who want to start their family project without a male partner.
In Spain, the number of women who choose this option has not stopped growing, in parallel with an evident social change and the improvement of techniques.To put this into perspective, the percentage of unmarried mothers increased from 2% in 1975 to 46,79% in 2017, a huge leap that reflects new family models and greater autonomy in deciding when and how to become a mother.
Profile and motivations of those who choose single motherhood
There is no single profile, but there are features that are repeated.: independent, informed women who take on the responsibility of raising children without another adult figure at home and who no longer want to postpone their desire to become mothers.
The reasons range from the legal right to reproduce, to the biological clock or the simple fact of not having found a partner.. Also weighing heavily is maternal instinct and the conviction that there are safe ways to achieve this without giving up on one's life plan.
Key differences between artificial insemination and IVF
The big difference is the place where fertilization occurs.In IVF, the egg and sperm meet in the laboratory, and the embryo is then transferred to the uterus; in AI, the meeting occurs naturally inside the fallopian tubes.
IVF is more complex and expensive, but offers higher pregnancy rates., especially after a certain age or when there are known causes of infertility. AI, on the other hand, offers simplicity, less medication, and a very comfortable process for the patient.
Knowing the differences between these techniques can help you make informed decisions.To learn more about the available options, we recommend consulting the complete guide to assisted reproduction methods and their advantages.
Phases of the artificial insemination process
Although it is a low-complexity treatment, AI is planned precisely to increase the chances of success.. Usually, the cycle includes four chained steps: ovarian stimulation, cycle control, sample preparation and the artificial insemination.
1) Gentle ovarian stimulation
For 10-12 days, low doses of hormones are administered to stimulate the ovary in a controlled manner. and obtain one or two mature follicles (avoiding too many to minimize the risk of multiple pregnancies). This phase is tailored to each individual patient, ensuring that the egg and sperm meet at the perfect time.
2) Cycle control and ovulation programming
Follicular maturation is monitored with ultrasounds and, if necessary, hormonal analysis.When one or two follicles reach about 16-18 mm, an injection is given to trigger ovulation in a specific window, so that insemination is scheduled for peak fertility times.
3) Preparation of donor semen
The sample is thawed on the same day of the procedure and is processed in the laboratory. to concentrate sperm with the best motility and quality. This step is key: it optimizes the sample so that it is at its best when the egg is available.
4) Insemination
The technique itself is quick and painless.Using a fine cannula, the sample is inserted into the uterus during a gynecological consultation. Sperm survive 3-5 days in the female reproductive tract, while the egg lasts about 24 hours, so timing is crucial for achieving fertilization.
Practical tipMany clinics recommend arriving with a slightly full bladder and about 30 minutes early. After AI, you can lie down for about 10 minutes; this rest hasn't been proven to improve pregnancy rates, but it's often done for convenience.
Less complexity and cost than other treatments
Artificial insemination is the simplest, least invasive and lowest cost assisted reproduction treatment.Artificial insemination (AI) involves introducing a sperm sample into the uterus, previously prepared in a laboratory to maximize its quality. For women without a male partner, donor sperm (DSI) is used, selected and validated by a bank under strict health controls.
AI respects the natural process as much as possibleFertilization occurs inside the body, in the fallopian tubes, as in a spontaneous pregnancy. Furthermore, in Spain, nearly 23.000 inseminations are performed each year, and the trend continues to rise, a testament to its widespread acceptance and safety.
For young women with good ovarian reserve and patent tubes, AI is often the best way to start.If it doesn't work after several attempts, the next logical step is in vitro fertilization (IVF) or other alternatives with excellent results.
Common medical requirements for AI eligibility
The ideal candidate is a woman with patent tubes, good ovarian reserve and age generally below 36-38 years.In any case, the assessment is individual: medical history, cycles, possible surgeries, blood tests (including AMH), and ultrasound are reviewed to estimate ovarian response and rule out any impediments.
If conditions are not optimal for AI, IVF or other alternatives are proposed directly.The goal is always to choose the technique with the best chance of success in the shortest possible time.
Sperm donor: anonymity, selection and dose reservation
In Spain, by Law 14/2006, donation is anonymous and the clinic is responsible for assigning the donor.Immunological compatibility and phenotypic similarity with the recipient are prioritized, in addition to a very thorough health and genetic screening to ensure safety.
Many banks allow reserving new doses from the same donor. for future pregnancies and thus attempt to ensure that siblings are biologically related. However, there is a legal limit on the number of births per donor (up to six), which limits the availability of more samples.
Success rates and how many attempts to make
Donor AI achieves around 20% pregnancy rate per cycle.When several attempts are made (3-4 is most common in those under 38), the cumulative effect increases the total probability to around 60% after four cycles, especially when using donor sperm.
If pregnancy is not achieved after 3-4 AIs, IVF is considered., where transfer fees can be as high as 40% and cumulatively climb to around 90% after three attempts with good predictions.
After insemination: what to do and what to avoid
No special rest is necessaryUnless medically advised, you can resume your normal life. It is advisable to avoid very intense exertion (lifting heavy weights or strenuous workouts), opting for gentle physical activity.
The most frequent symptoms in the first days are nonspecific.It's normal not to notice anything during the first week. Around day 10, you may experience light spotting, menstrual-like discomfort, or increased urination. A pregnancy test is recommended 15 days after the AI to avoid false results.
Regarding the sex of the baby, the chances of a boy or a girl are practically the same., and there is no reliable evidence to support "selecting" sex with AI. Regarding multiple pregnancies, in assisted reproduction the risk increases compared to the general population (around 15% versus 2%), mainly due to stimulation; even so, current figures are low with modern protocols.
Costs and access in Spain
The price varies according to technique and clinic. Approximately: AI with a donor €1.000-1.700; IVF with a donor €3.900-5.900; IVF with double donation €5.000-9.500; embryo adoption €1.900-4.000. Medication must be added to these amounts; with AI, this usually amounts to €200-300, while with IVF, stimulation can cost around €1.000-1.200, and endometrial preparation around an additional €300.
In public health, AI is offered in many autonomous communities with waiting lists that can reach two years.. . Up to 4 AI and 3 IVF sessions are usually covered (sometimes AI can be extended to 6 if it involves a donor), and there is usually an age limit of around 40 years, with nuances depending on the autonomous community and the center's criteria.
In the private sector, many clinics set the age limit at 50 years to start treatments., always after evaluating risks and health conditions. Always consult the center's criteria and the safest alternatives for your case.
Emotional and legal support
Law 14/2006 recognizes the right of any woman over 18 years of age with legal capacity to access assisted reproduction., without requiring a partner. The anonymity of gamete and embryo donors is mandatory, and centers must ensure compliance with health controls.
About infertility in single womenSterility/infertility is usually defined when pregnancy is not achieved after a reasonable number of therapeutic attempts (e.g., several cycles of AI and/or IVF). Assessment is clinical and adjusted for age, ovarian reserve, and prior response.
On an emotional and logistical level, surround yourself with support.: family, friends, mothers' groups, psychological counseling if you wish. Raising a child alone is a wonderful challenge, and having a support network makes a huge difference in your daily life.
Frequently asked questions that should be clarified
Can I save donor sperm for a second child? Yes, at many banks. It's possible to reserve units to try for biological siblings, as long as there's availability and the legal maximum number of children born per donor (up to 6) is not exceeded.
Can I be a single mother through Social Security? It depends on the autonomous community. In several autonomous communities, single women and female couples have access to public assisted reproduction services; in others, access may be more restrictive. Your family doctor is the gateway to a referral center.
Can I repeat single motherhood? In the private sector, yes, with a fertility and treatment plan reassessment. If you plan to have more than one child, it's a good idea to ask about reserving doses from the same donor.
Can I try for twin pregnancies if I go alone? In IVF, transferring two embryos may be considered in very specific situations, but current practice prioritizes a single transfer to reduce maternal and perinatal risks. Safety comes first.
What happens if I don't have a male partner? With donor sperm and appropriate techniques (AI, IVF, embryo adoption), women who choose to do so can achieve pregnancy with high health and legal guarantees.
Are you thinking about artificial insemination?
The first visit has a key objective: to carefully define the best plan for you.Don't limit yourself to the basics: ask about success rates by age, stimulation protocols, options if AI fails, donor assignment criteria, and single-transfer policies.
With the budgets, he asks for total clarity: what's included (blood tests, ultrasounds, lab work, transfer, vitrification), what's not included (medication, additional tests), and how it's handled if you need more than one cycle. Avoiding surprises will help you decide with confidence.
