Sperm donor requirements go beyond a routine semen analysis. Infection screening, medical and family history, genetic assessment and freezing performance all matter. A sperm bank’s decision is a safety and program-eligibility judgment—not a verdict on a man’s worth or his ability to become a parent.
A sperm bank may decline an otherwise healthy applicant because donation requires several forms of screening. Acceptance rates and timelines vary by program; a single rejection percentage should not be applied to all banks.
Screening for donation
Semen characteristics are one part of eligibility, alongside infection testing, medical and family history, genetic assessment and counseling. This is risk reduction, not a search for a genetically perfect person.
The Multi-Layered Gatekeeping
The screening process functions like a series of increasingly narrow filters:
- Semen assessment: Programs assess semen characteristics and often post-thaw performance; donation criteria can be stricter than personal fertility reference values.
- Infection screening: Testing, timing and eligibility depend on the organism, history and applicable rules.
- Systemic Health Screening: A comprehensive look at the body’s internal metrics: liver function, kidney health, blood glucose, and hematology.
- Genetic assessment: Family history and carrier screening reduce uncertainty but cannot exclude all inherited conditions.
- Counseling: Psychological history and implications of donation require individualized assessment, not a blanket judgment about depression.
Screening cannot eliminate every inherited or infectious risk. Its purpose is informed, safer donation, with clear counseling for donors and recipients.
A donor rejection does not diagnose infertility or show that a man is generally unhealthy. The reason for the decision matters.
Donor sperm is one family-building option in appropriate circumstances. Depending on the diagnosis, other approaches may include treatment, sperm retrieval, IVF with ICSI or different routes to parenthood.
The donor-selection process should not be used as a population health survey. Program requirements differ from the thresholds used in a personal fertility evaluation.
A decision about eligibility, not worth
Anyone concerned about fertility should seek an individual assessment rather than interpret donor eligibility as a verdict on parenthood.

Screening has limits
Donor eligibility is defined by clinical guidance and applicable rules, and residual risk remains after screening. ASRM gamete and embryo donation guidance (2024).
