What is IUI?
Intrauterine Insemination (IUI) is a widely known fertility treatment that involves preparing a concentrated sperm sample and placing it directly into the uterus during the most fertile part of the cycle. It is considered a gentle, minimally invasive option that may be recommended before more advanced treatments like IVF.
At Lifespan Birth, we do not recommend IUI. Instead, we recommend ICSI (Intracytoplasmic Sperm Injection), a more advanced procedure that achieves higher precision and often greater success rates, particularly for patients who might otherwise consider IUI or IVF.
Who Typically Considers IUI?
IUI may be an appropriate treatment for:
- Mild male factor infertility – Low sperm count, motility, or morphology slightly below normal.
- Cervical factor infertility – Abnormal cervical mucus or scarring that makes it difficult for sperm to reach the egg.
- Unexplained infertility – When no clear cause has been found, IUI offers a less invasive first option.
- Ovulatory dysfunction – For women with irregular or absent ovulation, IUI may be combined with medication to improve timing.
- Single women or same-sex couples – IUI can be performed with donor sperm as part of a personalized fertility plan.
Success Rates and Expectations
IUI success rates vary widely depending on age, reproductive health, and underlying causes of infertility. Many patients may need several cycles to achieve results.
We focus on ICSI because:
- ICSI is more effective than IUI in overcoming male factor infertility
- Fewer cycles may be needed, reducing emotional and financial stress
- Embryo selection and testing can be combined with ICSI to further increase success rates
Your doctor will discuss your individual chances of success based on your medical profile and treatment plan.
Risks and Considerations
IUI is generally safe but can involve risks such as:
- Mild cramping or spotting after the procedure
- Ovarian hyperstimulation syndrome (OHSS) in rare cases when fertility drugs are used
- Emotional stress if multiple cycles are needed before success

FAQs About IUI
IUI involves placing a prepared sperm sample into the uterus. It is suitable for couples with mild infertility, unexplained infertility, cervical factor concerns, and for single or same-sex couples using donor sperm.
Some patients achieve results within a few cycles, while others may require more depending on age and health.
The procedure is generally safe, with occasional mild cramping or spotting. Rarely, fertility medications can cause ovarian hyperstimulation syndrome (OHSS).
