Are you considering becoming a sperm donor? In the UK, donor sperm helps hundreds of intended parents each year—from single women and LGBTQ+ couples to heterosexual couples experiencing fertility challenges. This guide provides a clear overview for 2025: eligibility criteria, medical standards, step-by-step process, legal protections, and donor remuneration.

Why Become a Sperm Donor? Motivations & Benefits

  • Altruistic impact: You help individuals and couples fulfil their dream of parenthood.
  • Comprehensive health screening: Free blood tests, semen analysis and genetic screening.
  • Donor remuneration: Typically £100–£200 per donation to cover your time and travel.
  • Genetic legacy: You contribute your DNA without the immediate responsibilities of parenthood.

Eligibility Requirements: Age, Health & Reliability

Fertility clinics adhere to strict HFEA (Human Fertilisation & Embryology Authority) guidelines and the HTA’s European Tissue and Cells Directive, but typically you must:

  • Be aged 18–39: Some clinics accept donors up to 40, although sperm quality may decline after 39 (WHO Manual).
  • Be in good health: No HIV, hepatitis B/C or other infectious diseases; no inheritable genetic disorders; BMI under 30.
  • Be reliable: Commit to donating once or twice a week for 6–12 months and adhere to lifestyle guidelines.

Medical Standards & Quarantine

Under the European Directive, each sample must contain at least 15 million sperm per mL with ≥32% progressive motility. Samples are frozen at –196 °C, held in quarantine for 180 days, then retested under HTA protocols before release. Clinics follow HFEA’s Code of Practice for donor screening and storage.

Donation Process: Step by Step

  1. Application & Interview: Complete an online questionnaire and meet with clinic staff to discuss your medical and family history.
  2. Screening Phase: Provide blood and urine samples, two semen analyses, a genetic panel and undergo a physical examination.
  3. Donation Appointments: Attend the clinic once or twice weekly to provide samples in a private collection room; maintain 2–3 days of abstinence before each appointment.
  4. Cryopreservation: Each sample is divided into multiple vials and frozen in liquid nitrogen for future use.
  5. Quarantine & Release: After 180 days, samples undergo a second infection screening; approved samples are released for recipient use.
  6. Completion & Extension: Most donors complete 10–25 donations; extensions may be possible in consultation with the clinic.

Remuneration & Tax Considerations

Donor payments of £100–£200 per donation are typically made via bank transfer. These payments are considered non-taxable reimbursements for expenses and inconvenience, provided they remain within HTA-approved limits. Keep receipts for travel and related costs.

Preparation & Practical Tips

  1. Maintain 2–3 days of abstinence before each donation.
  2. Limit alcohol and tobacco—improvements in sperm quality often appear after 6–8 weeks.
  3. Eat a balanced diet rich in zinc, folic acid and omega-3 fatty acids (Nature 2020).
  4. Reduce stress through light exercise and adequate sleep.
  5. Have your ID, NHS card and family medical history readily available.
