Introduction
Intrauterine Insemination (IUI) is one of the most widely used fertility treatments for couples facing difficulty in conceiving. This minimally invasive procedure involves placing concentrated and washed sperm directly into a woman's uterus, increasing the chances of fertilization. However, one of the most critical factors influencing the success rate of IUI treatment is age.
At Pratham IVF, we understand the emotional and physical journey of fertility treatments, and we aim to provide the most effective and affordable solutions for couples trying to conceive. In this blog, we will explore how age affects IUI success rates, its impact on egg quality, and what steps can be taken to maximize your chances of conception.
What is IUI, and How Does It Work?
Intrauterine Insemination (IUI) is a fertility treatment designed to assist couples struggling with infertility. During this procedure, a semen sample is collected, washed, and concentrated before being placed directly into the uterus using a thin catheter. The goal is to facilitate the movement of healthy sperm toward the fallopian tubes, where fertilization occurs.
Key Factors for IUI Success:

Healthy Egg Quality

Good Sperm Motility and Count

Open and Functional Fallopian Tubes

Proper Ovulation Timing

Age of the Woman
Among these factors, age plays a pivotal role in determining the outcome of the IUI procedure.
The Impact of Age on IUI Success Rates
Age significantly influences a woman's fertility due to changes in egg quality and ovarian reserve. As a woman ages, the number and quality of her eggs decline, directly affecting the likelihood of conception through IUI treatment.
Success Rates of IUI Based on Age
- Under 30 Years: The highest success rates, with an average pregnancy rate of 15-20% per cycle.
- 30-35 Years: The success rate remains relatively high at 10-15% per cycle.
- 35-40 Years: A gradual decline, with IUI success rates dropping to around 8-10% per cycle.
- Above 40 Years: The success rate reduces to 5% or lower per cycle, as the egg quality significantly deteriorates.
How Age Affects Egg Quality and Quantity
Egg quality is a crucial factor in conception. Younger women generally have a higher number of healthy, chromosomally normal eggs, which increases the chances of successful fertilization and implantation. As a woman ages, the likelihood of chromosomal abnormalities in eggs increases, leading to a higher risk of miscarriage or unsuccessful implantation. Ovarian Reserve refers to the number of eggs a woman has left in her ovaries. This reserve declines over time, reducing the probability of releasing a viable egg during ovulation.
Age and Hormonal Changes Impacting IUI Success
Aging also affects hormonal balance, which plays a vital role in fertility. Hormones such as FSH (Follicle-Stimulating Hormone) and AMH (Anti-Müllerian Hormone) regulate ovarian function and egg development.
- FSH Levels: Higher FSH levels indicate lower ovarian reserve and reduced egg quality.
- AMH Levels: Lower AMH levels suggest a diminished egg supply, making it harder to achieve pregnancy through IUI treatment.
Ways to Improve IUI Success Rate at Any Age
While age is a significant factor, there are several ways to optimize your chances of conception through IUI treatment:

Early Fertility Evaluation
If you are planning to conceive, consult a fertility specialist early to assess your ovarian reserve and reproductive health.

Lifestyle Modifications
Maintain a healthy diet, exercise regularly, and avoid smoking and excessive alcohol consumption to improve fertility.

Hormonal Support
Medications like Clomid or Gonadotropins can be used to stimulate ovulation and increase the number of mature eggs released.

Monitor Ovulation Closely
Proper timing of IUI procedure with ovulation induction increases the success rate.

Consider Advanced Treatments
If IUI treatment is not successful after multiple cycles, treatments like IVF (In-Vitro Fertilization) may offer better success rates.
When to Consider IVF Instead of IUI?
For women above 35 years, multiple failed IUI cycles, or severe male infertility, IVF treatment is often recommended. IVF has higher success rates, especially for women with low ovarian reserve or poor egg quality.
