Intracervical insemination (ICI) offers couples and single prospective parents a gentle, flexible and cost-effective way to achieve pregnancy. This article explains—in everyday language—how ICI works, its pros and cons, and the points you should consider before your first attempt.
What Is Intracervical Insemination (ICI) and How Does It Work?
During intracervical insemination, fresh or thawed semen is placed as near as possible to the cervix using a needle-free syringe or an insemination cup. The procedure can be carried out in a clinic with professional support—for example from a midwife or fertility nurse—or at home in familiar surroundings.
After deposition, the recipient should stay lying down for about 15–30 minutes so that gravity and gentle uterine contractions can help the sperm reach the uterus.
Some sources describe home inseminations where the semen is deposited slightly further from the cervix as intravaginal insemination (IVI). In everyday speech, ICI and IVI are often used synonymously.
Why Do People Choose Intracervical Insemination?
ICI combines privacy and lower cost with minimal medical intervention. It can be a good option if fertility challenges are mild or if you wish to use donor sperm without immediately attending a fertility clinic.
Key Considerations Before ICI
You will need healthy reproductive anatomy (open fallopian tubes) and accurate cycle tracking. Use ovulation tests or a period-tracking app to pinpoint ovulation. If you plan to use donor sperm, washed samples are advised because they decrease infection risk—provided you tolerate them well.
- Health check: general health review and current vaccination status.
- Genetic screening: especially sensible when using an anonymous or private donor.
- Legal aspects (UK): At-home ICI with donor sperm is legal, but parental status and donor responsibilities are governed by the Human Fertilisation and Embryology Act and differ slightly between England, Wales, Scotland and Northern Ireland. A written donor agreement and advice from a specialist fertility solicitor are strongly recommended.
- Equipment checklist: sterile specimen cup, needle-free syringe or small catheter, latex or nitrile gloves, fertility-friendly lubricant, disinfectant.
Risks & Safety of At-Home ICI
- Infection risk: unsterile equipment or untreated semen can transmit bacterial or viral infections (e.g. HIV, hepatitis B, chlamydia).
- Injury risk: incorrect catheter use could damage the vaginal or cervical lining.
- Poor timing: success rates drop without precise cycle tracking.
- Emotional strain: repeated failed attempts can be stressful—consider professional support if needed.
Tips to Maximise Your Chances
- Track your cycle precisely (basal-body-temperature charting, LH tests or an ovulation-tracking app).
- Optimise sperm quality: 2–3 days’ abstinence, no smoking or heavy alcohol, balanced diet.
- Use fertility-friendly lubricants instead of standard products.
- Gently tilt the pelvis or raise the legs—this may help sperm transport.
- An orgasm directly after insemination may assist through uterine contractions (evidence is limited).
Quick Comparison of Fertility Methods
- ICI / IVI – at-home insemination
Semen is placed just in front of the cervix with a syringe or cup. Suitable for mild fertility issues or donor sperm; lowest cost, maximum privacy. - IUI – intra-uterine insemination
Washed sperm is passed directly into the uterus via catheter. Used for moderate male-factor issues, cervical problems or unexplained infertility; simple outpatient procedure, medium cost. - IVF – in-vitro fertilisation
Multiple hormonally stimulated eggs are fertilised with prepared sperm in the lab. Standard for blocked tubes, endometriosis or failed IUI; higher success rates, higher cost. - ICSI – intracytoplasmic sperm injection
A single sperm is micro-injected into the egg. Precision option for severe male-factor infertility or TESE samples; most expensive, but the best chance when sperm quality is very low.
Step-by-Step Guide to Performing ICI
- Collect the sample: use a sterile container—avoid any contaminants.
- Prepare the syringe: fill a sterile, needle-free syringe or catheter.
- Get into position: lie on your back with hips slightly raised.
- Insert the syringe: gently advance until just in front of the cervix.
- Release: slowly expel the semen.
- Optional boost: orgasm may enhance uterine contractions.
- Rest: remain lying down for 20–30 minutes.
Pros & Cons
- Lower cost than IUI / IVF
- High privacy and lower stress
- Flexible timetable—no clinic appointments
- No hormonal stimulation required
- Lower success rate than IUI / IVF
- No immediate medical help if complications occur
- Requires accurate cycle monitoring
- Potential legal uncertainties with private sperm donation
What Are the Success Rates for Intracervical Insemination?
Success varies depending on age and overall health:
- Under 35: 10–20 % per cycle (average ~15 %).
- Aged 35–40: about 10 % per cycle.
- Over 40: 5 % or less per cycle.
Carrying out several consecutive cycles greatly increases cumulative pregnancy chances.
When Should You Seek Professional Advice?
- < 35 years old: after 6–12 unsuccessful ICI cycles.
- 35–40 years old: after 6 cycles.
- > 40 years old: seek fertility advice early.
- If you have known endometriosis, PCOS or severely abnormal semen parameters, contact a fertility specialist straight away.
