Donor Sperm IUI: The Process Step by Step

Who typically uses donor sperm IUI?

Donor sperm IUI is one of the most straightforward assisted reproduction paths. People who pursue it include:

• Single people who want to conceive without a male partner
• Same-sex female couples where neither partner has sperm
• Heterosexual couples where the male partner has azoospermia (no sperm) or severe sperm abnormalities not suitable for ICSI retrieval
• Couples with a heritable genetic condition who wish to avoid transmission

A thorough evaluation before starting — including confirming that the tubes are open (typically via HSG) and that ovarian function is adequate — helps ensure that IUI is the appropriate first step. 1Ref 1Practice Committee of the American Society for Reproductive Medicine (2021).Fertility evaluation of infertile women: a committee opinion.Guidance that tubal patency and ovarian function should be confirmed before proceeding with IUI; three to six cycles are appropriate before escalating treatment; the IUI procedure itself including timing and technique If significant tubal disease or severely diminished ovarian reserve is found, IVF may be recommended instead.

How do I choose a sperm bank?

In the United States, sperm banks that sell donor sperm for clinical use are regulated by the FDA under 21 CFR Part 1271. All donors must be screened and tested for communicable diseases including HIV, hepatitis B and C, syphilis, chlamydia, gonorrhea, HTLV, and CMV. 2Ref 2U.S. Food and Drug Administration (2024).Recommendations for Determining Eligibility of Donors of Human Cells, Tissues, and Cellular and Tissue-Based Products (HCT/Ps).FDA regulatory framework for sperm donor screening and testing requirements under 21 CFR Part 1271, including required infectious disease tests and consent documentation that terminates donor parental rights

Beyond the FDA baseline, banks vary in: - Genetic panel depth: the number of carrier conditions screened (some banks screen for 200+ conditions) - Donor profile information: some offer childhood photos, extended personal histories, audio recordings, and staff-written impressions - Open vs. closed ID donors: an open-identity (or ID-release) donor agrees to allow offspring access to identifying information when they turn 18 - Available units and shipping logistics

Ask your clinic whether they have preferred banking relationships or specific processing requirements.

What does the IUI cycle look like?

Natural cycle IUI — If you ovulate regularly, IUI can be timed to your natural LH surge: 1. Use an OPK at home starting around day 10–12 of your cycle 2. When the LH surge is detected, contact your clinic 3. The IUI is typically performed 24–36 hours after the LH surge

Stimulated cycle IUI — Your clinician may add low-dose oral medication (clomiphene or letrozole) or injectable gonadotropins to support follicle development and improve timing: 1. Medications begin early in the cycle 2. Ultrasound monitoring confirms follicle growth 3. A trigger injection (hCG or GnRH agonist) times ovulation 4. IUI is performed 24–36 hours after the trigger

The procedure itself takes only a few minutes: a thin catheter is passed through the cervix and washed, concentrated sperm is deposited in the uterine cavity. Most people describe mild cramping, similar to period pain, and are able to leave promptly. 1Ref 1Practice Committee of the American Society for Reproductive Medicine (2021).Fertility evaluation of infertile women: a committee opinion.Guidance that tubal patency and ovarian function should be confirmed before proceeding with IUI; three to six cycles are appropriate before escalating treatment; the IUI procedure itself including timing and technique

A pregnancy test is typically done two weeks after the procedure.

What success rates should I expect?

Success per IUI cycle depends mainly on:

• Age: per-cycle pregnancy rates decline with the recipient's age, reflecting egg quality
• Ovulatory function: women with regular ovulation generally have better outcomes than those with irregular cycles
• Number of cycles: cumulative success over three to four cycles is meaningfully higher than a single attempt 1Ref 1Practice Committee of the American Society for Reproductive Medicine (2021).Fertility evaluation of infertile women: a committee opinion.Guidance that tubal patency and ovarian function should be confirmed before proceeding with IUI; three to six cycles are appropriate before escalating treatment; the IUI procedure itself including timing and technique

The ASRM evidence-based guideline recommends that couples with unexplained infertility typically undergo a course of three to four ovarian stimulation and IUI cycles before escalating to IVF. This principle generalizes to single recipients and same-sex couples with no identified female factor infertility: a reasonable trial of IUI before moving to IVF is both clinically sound and cost-effective. 3Ref 3Practice Committee of the American Society for Reproductive Medicine (2020).Evidence-based treatments for couples with unexplained infertility: a guideline.ASRM recommendation that 3–4 cycles of ovarian stimulation with oral agents and IUI are appropriate initial therapy before escalating to IVF; evidence basis for the IUI trial before IVF recommendation

If pregnancy does not occur after three to six IUI cycles, your clinician will typically recommend reassessing and considering IVF.

What legal and emotional considerations apply?

In the United States, sperm purchased from an FDA-regulated bank with appropriate consent documents generally establishes clear parental rights for the birth parent and any co-parent, while terminating the donor's parental rights. Laws on parental presumption for non-biological co-parents (in same-sex couples, for example) vary by state. Consulting a reproductive attorney before proceeding is advisable. 2Ref 2U.S. Food and Drug Administration (2024).Recommendations for Determining Eligibility of Donors of Human Cells, Tissues, and Cellular and Tissue-Based Products (HCT/Ps).FDA regulatory framework for sperm donor screening and testing requirements under 21 CFR Part 1271, including required infectious disease tests and consent documentation that terminates donor parental rights

The decision to use a donor and the repeated two-week waits between insemination and a pregnancy test can be emotionally demanding. It is normal to feel grief, hope, uncertainty, and relief in the same cycle. Many people find support from online communities, a therapist familiar with fertility, or peer support groups specific to donor conception.
