Deciding on the best fertility treatment can feel overwhelming, especially if you have been diagnosed with polycystic ovary syndrome (PCOS). If you are exploring your options to start a family and wondering whether assisted reproductive technologies such as intrauterine insemination (IUI) are worth considering, you are not alone.
Understanding how PCOS affects fertility, the effectiveness of IUI when you have it, and what to expect from the process can help you make a more confident and informed decision about your next steps on your path to parenthood.
How does PCOS affect fertility?
PCOS is a hormonal condition that causes hormonal imbalances, affecting women of reproductive age. If you have PCOS, you may experience irregular periods, excessive hair growth, acne, and infertility due to infrequent or absent ovulation.
Women with PCOS often have higher levels of androgens (male hormones) and suffer from insulin resistance. Hence, disrupting your regular menstrual cycle due to low levels of progesterone and high levels of androgen and causing high levels of insulin.
Your ovaries contain several follicles that grow and burst every month, releasing an egg into one of your fallopian tubes if you have a normal menstrual cycle.
When you have PCOS, you are unable to grow or release these follicles, leading to a buildup in the ovaries that resembles cysts. PCOS can also impact the uterine lining, making it difficult for mature eggs to implant on it.
What are some common fertility challenges experienced if you have PCOS?
Some common fertility challenges include:
Irregular or absent periods, which make it harder to predict ovulation.
Irregular ovulation and anovulation (not releasing an egg during the menstrual cycle).
Hormone imbalances, including high insulin due to insulin resistance and high androgen levels.
Presence of ovarian cysts
Increased risk of miscarriage and complications during pregnancy.
When is IUI suitable for women with PCOS?
IUI is commonly recommended for women with PCOS who do not ovulate regularly and have been unsuccessful in conceiving despite making lifestyle changes and taking oral medications.
IUI is particularly useful for couples that do not suffer from low sperm count and have no significant issues with their fallopian tubes.
IUI may be offered after first-line treatments like clomiphene citrate (Clomid) or letrozole if pregnancy has not occurred after several cycles.
If you have PCOS and are unsure whether IUI is suitable for you, it is best to visit your fertility clinic and discuss with a fertility specialist your current symptoms and the possible next steps for you. Request an appointment with Thomson Medical today.
Is IUI effective for women with PCOS?
IUI can be an effective treatment for women with PCOS, especially when combined with fertility drugs such as clomiphene citrate, also known as Clomid. Clomid is an oral medication primarily prescribed to stimulate ovulation in women experiencing infertility due to irregular or absent ovulation.
Ovulation-inducting medications like these make your brain think your oestrogen levels are lower than they actually are. Thus, your pituitary gland responds by releasing more of the follicle-stimulating hormones (FSH) and luteinising hormones (LH). These hormones stimulate your ovaries to develop and release eggs.
Afterwards, specially prepared sperm is directly inserted into the uterus using an IUI catheter around the time of ovulation, thereby increasing the chances of fertilisation and a successful conception.

What are the success rates of IUI in PCOS?
Success rates for IUI vary widely and depend on age, cause of infertility, whether ovulation is achieved, semen quality and any underlying health conditions.
For women with PCOS, live birth rates per IUI cycle are typically around 10-20%. The use of ovulation induction medications can improve chances of success. Multiple IUI cycles may also be recommended to increase the chance of a successful conception.
What can I expect during IUI treatment if I have PCOS?
If you have PCOS and are undergoing an IUI treatment cycle, you can expect the following:
Ovulation medications may be prescribed to stimulate egg growth.
Regular and close monitoring with ultrasound scans and hormonal assessment to assess follicle development and ensure optimal timing for the IUI procedure.
Once the egg is mature, an injection may trigger ovulation.
A concentrated sperm sample is carefully inserted into the uterus using an IUI catheter at the optimal moment.
You may resume usual activities shortly after the procedure.
Additional medications such as progesterone supplements may be provided after the procedure to help improve the chances of a successful conception.
A follow-up will occur two weeks later to check for a successful pregnancy through blood tests or pregnancy tests.
What are some factors that influence IUI success with those diagnosed with PCOS?
Some factors to consider include:
Age and overall reproductive health:
Age plays a crucial role in fertility.
Women under 35 generally have higher success rates with IUI compared to those over 35.
Body mass index (BMI):
Maintaining a healthy weight through diet and exercise can significantly improve ovulation and enhance the effectiveness of IUI.
For overweight women with PCOS, weight loss has been linked to better fertility and more successful IUI outcomes.
Sperm quality and quantity:
The quality of the sperm used in IUI can affect success rates.
Ensuring that sperm is well-prepared and healthy is crucial for maximising the chances of conception.
Use of ovulation induction medication and correct timing of insemination:
Women with PCOS may have irregular ovulation, which can affect the timing and success of IUI.
Successful ovulation induction through medications like Clomid or letrozole can significantly enhance the chances of a successful IUI.
Absence of other fertility issues:
Addressing other health conditions related to PCOS, such as insulin resistance, can positively impact IUI success rates.
Medications like Metformin may be prescribed to manage insulin levels and enhance fertility
How many IUI cycles should I try if I have PCOS before I try other fertility treatments?
It is usually recommended to try between 3 and 6 IUI cycles with ovulation induction before considering alternatives like in vitro fertilisation (IVF). If you do not become pregnant after several cycles, your doctor may discuss the next possible steps and alternative fertility treatments for you.
If you recently had a failed attempt at pregnancy using IUI, it is best to discuss with your fertility specialist what other fertility treatments can be tailored for you. Request an appointment with Thomson Medical today.
What other fertility treatments are available for me if I have PCOS?
If IUI is unsuccessful, other options include:
IVF
Lifestyle changes and weight management.
Gonadotropin injections for ovarian stimulation.
Surgery, such as ovarian drilling (rarely used).
FAQ
Does PCOS lower IUI success rates?
Women with PCOS may have slightly lower success rates compared to those with unexplained infertility, but the difference is often mitigated with the use of ovulation induction medication and proper monitoring.
Are special medications needed for PCOS patients?
Most IUI cycles for women with PCOS use ovulation induction medications like clomifene, letrozole, or gonadotropins, which help stimulate egg growth and increase the chances of successful ovulation.
Is IUI safe for women with PCOS?
IUI is generally considered safe. The main risks are related to ovulation-inducing medications, such as ovarian hyperstimulation syndrome (OHSS) and a slightly increased risk of multiple pregnancies.
Is it possible for women with PCOS to get pregnant using IUI?
Yes, many women with PCOS have successfully become pregnant through IUI, particularly when combined with medication to regulate ovulation.
Who is not a suitable candidate for IUI?
IUI may be less suitable if there are problems such as blocked fallopian tubes, very poor sperm quality, or severe endometriosis. In these cases, IVF may be recommended instead.
What is the best treatment for those diagnosed with PCOS to get pregnant?
First-line treatments typically include lifestyle change, weight management and medications like clomifene or letrozole. If these are not effective, IUI or IVF may be recommended.
Does PCOS affect implantation?
PCOS can sometimes affect the lining of the uterus and hormone levels, which may influence implantation. However, many women with PCOS go on to have healthy pregnancies.
Is IUI successful on the first try?
It is possible but uncommon. Most women need several cycles before achieving pregnancy through IUI.
