At-Home Insemination: How ICI Works, Safely and Legally

At-home insemination lets you try to conceive without intercourse and without a clinic, using a partner’s semen or donor sperm. It is common among single people and same-sex couples, and among couples for whom intercourse is difficult. Done carefully, it is simple. The parts that need care are the device, the sperm source, the timing and, with a known donor, the law. This guide covers each, using FDA rules, ASRM and ACOG guidance and published research.

What is at-home insemination (ICI)?

At-home insemination is usually intracervical insemination (ICI): semen is placed in the vagina, close to the cervix, with a needle-free syringe, around the time of ovulation. From there, sperm travel through the cervix and uterus to the fallopian tubes on their own.

It is different from IUI. In IUI, the semen is first "washed" in a lab to concentrate the sperm and remove seminal fluid, and a clinician passes a catheter through the cervix to place the sperm in the uterus.¹ ASRM explains the washing step is needed because seminal fluid can cause severe cramping in the uterus.¹ That is why, at home, semen should only ever be placed in the vagina. See IUI vs IVF for when a clinic treatment makes more sense.

Choosing an insemination kit

FDA classifies an "at home intravaginal insemination system", a syringe or catheter with or without a collection cup that delivers semen to the vaginal canal, as a Class II medical device reviewed through the 510(k) pathway.² The Mosie Baby Kit was cleared this way in November 2023, for people who have not been able to conceive through intercourse or choose not to, using partner semen or donor sperm.³ Two other kits have also been cleared under the same code.

Not every product sold for home insemination has been reviewed. MakeAMom, a popular reusable kit, states its products are not medical devices, and we found no FDA clearance for it. Use only a device made for insemination, and never a syringe with a needle. When you choose a kit, check its FDA status, sperm-safety testing and cost per attempt.

Choosing a sperm source and screening

Donor sperm from a bank

Sperm banks are regulated by FDA under 21 CFR Part 1271. Before donor sperm can be released, the bank must determine the donor is eligible through screening and testing.⁶ Required tests for reproductive donors include HIV-1 and HIV-2, hepatitis B, hepatitis C, syphilis, chlamydia and gonorrhea, and leukocyte-rich donations also need testing for HTLV and CMV.⁴ For anonymous semen donors, the bank must collect and test a new sample at least 6 months after the donation before releasing it.⁴ Follow the bank’s instructions for shipping, storage and thawing exactly, and use the sample within the time it specifies.

A partner

FDA’s donor-eligibility rules do not apply to reproductive cells from a sexually intimate partner of the recipient.⁵ If you and your partner have not been tested for sexually transmitted infections recently, it is reasonable to ask a doctor about testing before you start.

A known donor

A known donor who is not your sexual partner is in neither group. FDA’s requirements apply to establishments such as banks and clinics that perform donor-eligibility functions,⁶ so in a private arrangement no one screens the donor unless you arrange it. A practical minimum is to ask a doctor about the same infections FDA requires banks to test for, and to repeat testing as advised.⁴

When to inseminate

In a study of 625 cycles, conception happened only when sex took place during a six-day window ending on the day of ovulation, and the chance ranged from about 10% five days before ovulation to about 33% on ovulation day.⁷ Because sperm from sex several days earlier could still lead to pregnancy, fresh semen gives you more than one day to work with. With frozen sperm, follow your bank’s or doctor’s advice on timing.

LH urine tests are one way to time it: ACOG says a positive result suggests ovulation will occur in the next 24 to 48 hours.⁹ Our fertile window guide explains how to find yours.

How to do at-home insemination, step by step

1. Read the kit instructions in full before your fertile window starts. In FDA’s review of the Mosie Baby Kit, a usability study tested whether people could do the procedure from the labeling alone, which is why the instructions matter.³
2. Prepare the sample. For fresh semen, collect it in the kit’s cup. For frozen sperm, follow the bank’s thawing protocol exactly.
3. Draw up and release the sample in the vagina exactly as the kit instructions describe, never past the cervix.¹
4. Note the date so you know when a pregnancy test can work.

If you have fever, severe pain, heavy bleeding or unusual discharge afterward, call a doctor.

Legal parentage: talk to a lawyer first

This is the step people most often skip. When you use a known donor, whether the donor or your partner is a legal parent depends on your state’s law and sometimes on how the insemination was done. ASRM notes that parentage laws vary from state to state, that rights legally granted in one jurisdiction do not necessarily cross state lines, and that a legal consultation is suggested to determine each partner’s parental rights.⁸ Before you inseminate with a known donor, talk to a family law attorney who works with assisted reproduction about a written agreement and any steps your state may require to secure parentage. We cannot give legal advice for your situation.

When to see a doctor

ACOG recommends an evaluation after 12 months of trying under 35, after 6 months at 35 or older, and now if you are over 40.¹⁰ Go sooner if your periods are irregular or absent or you have a known condition such as endometriosis. A specialist can check ovulation and your tubes, and offer IUI, which places washed sperm in the uterus.¹ See when to see a fertility specialist, and the Treat hub for all options.
