Known Sperm Donation — How It Works

1. What is Known (Directed) Sperm Donation?

Known sperm donation, also called directed donation, is when the donor is not anonymous and is chosen by the intended parent(s). This can be a friend, acquaintance, or someone selected through a platform.

In this arrangement, the donor and recipient agree in advance on the donation, but the entire process is still carried out under medical and legal supervision in a licensed fertility clinic.

2. Where This Is Possible

Directed sperm donation is permitted in several regulated countries, particularly when carried out through licensed fertility clinics

  • Belgium
  • Denmark
  • Netherlands
  • United Kingdom
  • Sweden
  • Finland
  • Greece
  • Iceland
  • Canada
  • United States (varies by state and clinic)
  • Australia (varies by state)
  • New Zealand
  • Some South American Countries

Belgium is one of the most commonly referenced systems due to its structured legal and clinical framework, and will be used here as a reference example to explain the full process.

3. How Known Donation Actually Works

In Belgium, known sperm donation is possible, but it must always be processed through a licensed fertility clinic.

Key principles:

The recipient refers to the woman who wishes to become a mother, and the donor refers to the man who provides the sperm.

  • The donor and recipient can know each other personally (e.g., friends or chosen matches).
  • The clinic supervises and formalises the entire process.
  • Legal parentage is established before treatment begins.
  • The donor has no parental rights or obligations once the legal documents are signed.

4. Step-by-Step Process

Step 1: Initial Agreement Between Parties

The donor and recipient:

  • Meet and agree on the intention to proceed
  • Discuss expectations (contact, anonymity, future relationship)
  • Choose a fertility clinic together

This initial compatibility and trust is important, but it has no legal value until formalised in clinic documents.

Step 2: Medical Screening (Donor)

The donor undergoes full medical evaluation:

Semen analysis:

  • Sperm count
  • Motility
  • Morphology

Blood tests:

  • HIV (I & II)
  • Hepatitis B & C
  • Syphilis
  • Other infectious diseases

Genetic screening:

  • Carrier tests for hereditary conditions (depending on clinic protocol)
  • Family medical history

Step 3: Psychological Assessment

Both donor and recipient may be evaluated separately (sometimes with optional joint counseling):

  • Understanding of emotional implications
  • Motivation for donation
  • Long-term expectations
  • Ability to consent without pressure
  • Awareness of legal consequences

The goal is to ensure that both parties fully understand the nature of the arrangement.

Step 4: Legal Documentation

Before any donation takes place, both parties sign legal documents at the clinic.

These typically include:

  • Donor consent form
  • Recipient treatment agreement
  • Legal parentage declaration
  • Waiver of parental rights by the donor
  • Agreement on use, storage, or disposal of sperm samples

Once signed, the donor:

  • Has no legal rights or responsibilities toward any future child
  • Cannot be asked for financial or parental support

The recipient(s) are legally recognised as the sole parents.

Step 5: Donation Procedure

Before sample collection:

  • The donor is usually advised to abstain from ejaculation for 2–5 days
  • Avoid alcohol or substances that may affect sperm quality

The donation is performed in a clinic under controlled conditions.

To ensure sufficient samples:

  • The donor may be asked to provide multiple samples over a short period (often 2–3 donations within 1 week)

Step 6: Cryopreservation and Use

  • Samples are frozen and stored in liquid nitrogen
  • They can be used in future insemination cycles
  • Any unused samples are handled according to prior consent:
    • continued storage
    • destruction
    • or research use (only if explicitly allowed)

5. Recipient (Female Patient) Medical Process

Before insemination, the recipient undergoes fertility evaluation:

  • AMH (ovarian reserve hormone)
  • Antral follicle count (ultrasound)
  • Hormonal blood panel
  • Infectious disease screening
  • Genetic screening (if required)
  • Uterine and fallopian tube assessment

Based on results, the clinic determines treatment options:

  • Natural cycle insemination
  • Mild hormonal stimulation
  • Controlled stimulation with medication
  • IVF if medically indicated

6. Legal Parentage and Protection

Across Belgium and similar jurisdictions:

  • The donor is legally excluded from parenthood
  • The recipient(s) are the sole legal parents
  • The agreement is binding once signed at the clinic
  • This prevents future legal claims or obligations

7. Contact Between Donor and Recipient

In known donation:

  • The donor and recipient may meet before treatment
  • Some agreements allow limited ongoing contact
  • Others agree on no contact after donation

After birth, any relationship between donor and child is:

  • entirely optional
  • based on mutual agreement
  • not legally required

8. Timeline

The full process usually takes:

2 to 5 months depending on:

  • medical tests
  • genetic screening
  • psychological evaluation
  • clinic availability

9. Costs

  • Donation itself is altruistic (no payment to donor)
  • In most cases, the female recipient also covers the donor’s expenses as well as her own costs, including:
    • clinic procedures
    • laboratory costs
    • medication if needed
    • storage and logistics
    • travel and accommodation if applicable

10. Final Summary

Known sperm donation in the countries listed above is a structured, medically supervised process in which a donor and recipient—who may already know each other—proceed safely through a fertility clinic. Legal parentage is clearly defined before treatment, ensuring that the donor has no parental responsibilities, while the recipient(s) become the sole legal parent(s).
