Insemination at home: is it legal, is it safe, and how well does it work?

Check the law first. In some countries, insemination outside a clinic is a crime. In others, the donor becomes the child’s legal father. Where it is allowed, the main health risk is an infection from fresh sperm that was not tested and held. And at the cervix, insemination works less well than a clinic’s insemination into the womb.

This guide is published on the website of a man who offers to help a woman have a child: see the two options. The guide gives the facts as they are, whether or not they suit his offer. How these guides are written.

Is insemination at home legal where you live?

It depends on the country, so check the law before anything else. If the law where you live forbids it, do not do it: this page does not replace the law.

  • A crime in some countries. In France, insemination at home with donor sperm can bring up to 2 years in prison. In Greece, insemination outside a licensed clinic brings at least 3 months, and in Portugal up to 3 years. In Thailand, only a doctor may inseminate a woman, and others face up to 10 years in prison. In Saudi Arabia, placing sperm other than her husband’s in a woman can bring up to 5 years. In Cameroon, insemination with fresh donor sperm that was not tested first is a crime.
  • The donor can be the legal father. In the UK, the regulator (HFEA) says that for a single woman, a donor outside a licensed clinic “will be considered the legal parent”. In Denmark, a donor in an insemination without a health professional is the legal father. In Sweden, Finland and Germany, a donor at home can also be made the father.
  • A few places protect the donor at home too. In British Columbia (Canada), a donor is not a parent, even after insemination at home. The same holds in US states that use the 2017 Uniform Parentage Act, unless he agreed to be a parent.

The rules for 74 countries, with their laws, are in donor sperm, country by country.

What are the health risks?

The main risk is an infection that passes from the donor through his sperm. Semen can carry HIV, hepatitis B and C, syphilis, chlamydia and gonorrhoea, so US rules test every sperm donor for all of them.

This risk is not only in theory. In Australia, 4 of 8 women inseminated with sperm from one donor got HIV, before donors were tested for it (reported in The Lancet in 1985).

A negative test does not cover a recent infection. Just after an infection, tests cannot see it yet. This time is called the “window period”. So a test taken some weeks before does not prove that his sperm is safe today.

Why clinics freeze and hold donor sperm

Clinics freeze donor sperm, hold it, and test the donor again before they use it. If he had an infection too new to show at the first test, it shows at the second.

  • United States: sperm from an anonymous donor is held until he is tested again at least 6 months later.
  • Europe and the UK: it is held at least 180 days, or less when an extra blood test called NAT was done.
  • A donor you know: the US doctors’ society (ASRM) advises freezing his sperm, waiting 35 days and testing him again. After that, with a negative NAT test, the risk of a hidden HIV, hepatitis B or C infection is below 1 in a million.

Fresh sperm at home cannot be held this way. The ASRM says fresh sperm is justified only between sexual partners. Before anything, he should have recent laboratory tests, and so should you: see tests to ask a donor for.

How is insemination at home done?

At home, the sperm is placed in the vagina, close to the cervix (the opening of the womb). This is called intracervical insemination, or ICI. A medical review describes it as placing sperm in the vagina “using a small, needleless syringe or a cervical cap”.

Insemination into the womb itself (intrauterine insemination, or IUI) is done at a clinic. A health worker passes a thin tube through the cervix. A large US sperm bank tells its clients: “do not attempt an intrauterine insemination at home”.

Timing matters most. The fertile days are the 6 days that end on the day of ovulation, and the best are the 2 days before it. In the NHS’s words, ovulation “is usually 12 to 16 days before your next period is due”. But it moves: in one study, only about 3 women in 10 had all their fertile days between day 10 and day 17 of the cycle. Urine ovulation tests help: ovulation usually follows within about 2 days of a positive test. See the ovulation calculator.

How well does it work?

Insemination at the cervix works less well than insemination into the womb. The best evidence is a trial of 421 women at clinics in the Netherlands and Belgium, using frozen donor sperm, published in 2022. Each woman had up to 6 cycles. A baby was born to 24% of the women with ICI, and to 39% with IUI.

For IUI with donor sperm, about 1 cycle in 8 led to a birth in UK clinics in 2018 (13%). For single women it was 9% per cycle, mostly because they were older. The UK guideline (NICE) says 47% to 57% of women under 40 get pregnant within 6 cycles of IUI. NICE advises IUI rather than ICI, because it gives more pregnancies.

All these figures come from clinics. We found no large study of insemination done at home with fresh sperm, so we cannot give a figure for it.

When to see a doctor

See a doctor before you start, after 6 cycles without a pregnancy, and at once if you are 36 or older. These points come from the UK guideline (NICE):

  • Before you start: before donor insemination, a doctor should check that you ovulate. If your health history suggests a problem with your tubes, they should be checked too.
  • After 6 cycles of insemination without a pregnancy, ask for tests.
  • At 36 or older, or if you know of a fertility problem, ask to see a specialist at once.
  • A risk of HIV: if you learn that the donor may have HIV, ask at once about medicine called PEP. The NHS says it is for an exposure in the last 72 hours.

If the law where you live allows it

This website is one man’s offer. He is a healthy man in his forties. He helps a woman have a child in one of two ways: as a father who stays in touch from far away, or by artificial insemination, after which he steps away. In Option B, he helps only where the law allows it. See the two options.
