What is SO-IUI?
Couples with fertility issues have a lower chance of conceiving naturally. SO-IUI is an assisted reproductive technique that can help couples improve their chances of pregnancy.
During this procedure, fertility drugs are given to the patient, over the course of five days, to stimulate the production and ovulation of two to three mature ovarian follicles (eggs). On the day of the insemination, the prepared sperm is then placed directly into the uterus via intrauterine insemination.
Who Is Suitable for SO-IUI?
- Couples should be below 40 years of age and have a BMI below 30
- Females should have normal ovarian reserves at AMH / AFC / FSH levels
- The semen quality of males should be: satisfactory / mild sperm factor
- Females should have at least ONE patent fallopian tube
What other fertility treatments can I consider if I am not suitable for SO-IUI?
Couples who are not suitable for SO-IUI can consider other assisted conception programmes, such as In-vitro Fertilisation (IVF).
Intrauterine Insemination (IUI) Pregnancy Rates
At our clinic, we are committed to providing transparent outcomes data to help patients make informed fertility treatment decisions. Pregnancy rates following IUI can vary depending on several factors, including age, fertility diagnosis, sperm quality, and individual response to treatment.
Our clinical pregnancy rates for IUI are shown below:
| Age group | 2024 | 2025* |
|---|---|---|
| Patients ≤ 36 years old to Patients 36 years old and below | 21.05% | 7.50% |
| Patients ≥ 37 years old to Patients 37 years old and above | 30.00% | 28.60% |
*2025 results are based on cases completed to date.
Understanding the Results
Age is one of the many factors that can influence the success of IUI treatment. Pregnancy rates may fluctuate from year to year due to differences in patient demographics, underlying fertility conditions, treatment protocols, and the total number of treatment cycles performed.
While historical success rates can provide a useful benchmark, individual outcomes vary, and previous clinic-wide results do not guarantee future treatment success.
Our fertility specialists will assess your unique circumstances and recommend the most appropriate treatment plan to maximize your chances of achieving a pregnancy.
