Getting pregnant with a sperm donor involves choosing a donor source, selecting an insemination method, and timing the process to your ovulation cycle. The path looks different depending on whether you use a sperm bank or a known donor, and whether you inseminate at home or in a clinic. Here’s how each step works.
Sperm Bank vs. Known Donor
Most people choose between two routes: purchasing sperm from a cryobank or using someone they know personally. Each carries different logistics, costs, and legal considerations.
Sperm banks recruit donors who go through extensive screening. The FDA requires testing for HIV (types 1 and 2), hepatitis B and C, syphilis, chlamydia, gonorrhea, HTLV, and cytomegalovirus (CMV). Many banks add genetic carrier screening on top of that. Donor profiles typically include physical characteristics, education, medical history, and sometimes baby photos or audio interviews. A single vial generally costs between $1,300 and $2,100, with shipping adding another $340 to $415 depending on delivery speed.
A known donor is someone you personally select, such as a friend or family member. This route can feel more personal, but it requires more legal groundwork. The Academy of Adoption and Assisted Reproduction Attorneys considers several safeguards essential: a written legal agreement, independent legal representation for both parties, psychological consultation, and a full medical evaluation of the donor. In some states, a known donor may need to go through a formal termination of parental rights process. Without these protections, a known donor could potentially claim parental rights, or be held financially responsible for the child, depending on your jurisdiction.
Medical Steps Before You Start
Before purchasing sperm or scheduling insemination, it’s worth getting a fertility workup. A reproductive endocrinologist or OB-GYN can check that your fallopian tubes are open (typically through an imaging test called an HSG), confirm you’re ovulating regularly, and review hormone levels that affect egg quality. Identifying a blocked tube or hormonal issue early saves you from spending money on sperm vials that won’t result in pregnancy.
One often-overlooked test is your CMV status. CMV is a common virus that most people encounter at some point, and it’s usually harmless. But if you’ve never been exposed and contract it for the first time during pregnancy, there’s a 30 to 40% chance the virus reaches the fetus. Most babies born after a prenatal CMV infection are healthy, but 10 to 15% may develop complications like hearing loss or neurological issues. If your blood test shows you’re CMV-negative (meaning you’ve never been exposed), selecting a CMV-negative donor reduces this risk. If you’re CMV-positive, you already have antibodies and can choose a donor with either status.
Three Ways to Inseminate
The three main methods are intracervical insemination (ICI), intrauterine insemination (IUI), and in vitro fertilization (IVF). They differ in cost, complexity, and success rates.
Intracervical Insemination (ICI)
ICI places sperm near the cervix using a needleless syringe. It’s the simplest option and the only one you can do at home. You thaw the sperm vial according to the bank’s instructions, draw it into the syringe, insert it while lying down, and stay on your back for 15 to 30 minutes. After that, you go about your day normally. Home insemination kits are widely available and inexpensive. ICI uses “unwashed” sperm (meaning the seminal fluid hasn’t been separated out), which is fine for vaginal or cervical placement but not suitable for IUI.
Intrauterine Insemination (IUI)
IUI is performed in a clinic. A thin catheter delivers washed sperm directly into the uterus, bypassing the cervix entirely. This gives sperm a shorter distance to travel and typically produces better per-cycle success rates than ICI. The procedure takes only a few minutes and feels similar to a Pap smear. You’ll need to order IUI-ready (washed) vials from the sperm bank, since unwashed sperm can cause cramping and complications if placed directly in the uterus.
In Vitro Fertilization (IVF)
IVF involves stimulating the ovaries to produce multiple eggs, retrieving those eggs in a short outpatient procedure, fertilizing them with donor sperm in a lab, and transferring an embryo to the uterus several days later. It’s the most expensive and invasive option but also the most effective per cycle. IVF is typically recommended when IUI hasn’t worked after several attempts, when fallopian tubes are blocked, or when age is a significant factor.
How Age Affects Your Chances
Your age is the single biggest predictor of success with donor sperm, regardless of method. With IVF using donor sperm, women aged 18 to 34 have a live birth rate around 29% per cycle. For women over 37, that drops to about 14%. With donor insemination (IUI or ICI), the numbers are lower across the board: roughly 10 to 12% per cycle for younger women and 3 to 5% for women over 37.
These per-cycle numbers mean most people need multiple attempts. At a 12% success rate per cycle, for example, many people try three to six cycles of IUI before either conceiving or moving to IVF. Fertility medications that stimulate ovulation can improve these odds by increasing the number of eggs released in a given cycle.
Timing Insemination to Ovulation
Getting the timing right is critical. Ovulation occurs about 38 hours after the start of your LH surge, which is the hormonal signal your body sends to release an egg. You can detect this surge using over-the-counter ovulation predictor kits that test your urine.
Once you get a positive result, the standard approach is to inseminate the following day, just before or just after ovulation. For IUI at a clinic, your provider will schedule the appointment based on your surge timing. For home insemination, you’ll want your sperm vial already on hand, since shipping takes one to two days. Many people order two vials per cycle so they can inseminate on consecutive days and widen the window.
Some clinics also use ultrasound monitoring to track follicle growth and predict ovulation more precisely. This is especially useful if your cycles are irregular or if you’re using fertility medications.
What a Typical Cycle Looks Like
A standard month using donor sperm follows a predictable rhythm. Around cycle day one (the first day of your period), you’ll call your clinic if you’re doing monitored IUI, or simply start tracking at home. Between days 10 and 14 for most people, you’ll begin testing for your LH surge daily. When the test turns positive, you schedule or perform insemination within the next 24 hours. Then you wait about two weeks before taking a pregnancy test.
If it doesn’t work the first time, that’s completely normal. Most clinics suggest trying three to six IUI cycles before considering IVF, depending on your age and any underlying fertility factors. Each cycle requires a new sperm vial, so budgeting for multiple attempts is practical. At $1,300 to $2,100 per vial plus shipping, three IUI cycles with donor sperm can run $5,000 to $8,000 in sperm costs alone, before adding clinic fees for monitoring and the insemination procedure itself.
Choosing the Right Donor
Sperm banks let you filter donors by physical traits, ethnicity, education, and medical history. Beyond personal preferences, a few details are worth paying attention to. Look for banks accredited by the Association for Advancing Tissue and Biologics (AATB), which sets the highest industry standards for tissue safety and quality. Check whether the bank limits the number of families per donor, since some people prefer donors with lower family counts to reduce the chance of half-siblings in the same community.
You’ll also choose between anonymous (unidentified) and open-identity donors. Anonymous donors historically remained unknown, but the rise of consumer DNA testing has made true anonymity unrealistic. Open-identity donors agree to be contactable once offspring reach age 18. This distinction matters less for conception logistics and more for the future preferences of your child.
Finally, confirm the donor’s CMV status matches your needs, review the genetic screening results for carrier conditions relevant to your own background, and check whether the vial type (ICI or IUI) matches your insemination method. Ordering the wrong preparation is a surprisingly common and costly mistake.
