Ovulation induction
Ovulation induction explained: Helping your body ovulate naturally
If you’ve been trying to conceive and your periods are irregular or absent, your doctor may have mentioned ovulation induction.
While the name sounds complicated, the goal is actually quite simple: helping your body release an egg so pregnancy can occur naturally.
For many women, ovulation induction is one of the first fertility treatments recommended. It’s less invasive than IVF and can be highly effective for women who aren’t ovulating regularly.
Here’s what you need to know.
What is ovulation induction?
Normally, your body releases a group of eggs and one of these grows into maturity oeach month. However, some women ovulate irregularly or don’t ovulate at all, making it difficult to conceive.
Ovulation induction encourages your ovaries to mature and release, allowing timed intercourse thereby, increasing your chances of pregnancy.
Unlike IVF, fertilisation still happens naturally through intercourse or may be combined with intrauterine insemination (IUI).
Who might benefit from ovulation induction?
Ovulation induction may be recommended if you have:
- Polycystic ovary syndrome (PCOS)
- Irregular or absent periods
- Ovulation disorders
- Hormonal conditions affecting ovulation
- Unexplained infertility where improving ovulation may increase the chance of pregnancy
Before starting treatment, your fertility specialist will usually assess both partners to ensure there are no other factors that may affect your chances of conceiving.
How does ovulation induction work?
Treatment is designed to encourage the development of one healthy follicle, which contains the egg.
Step 1: Fertility assessment
Before treatment begins, your doctor may recommend:
- Blood tests to assess hormone levels
- An ultrasound to assess the ovaries and uterus
- A semen analysis for your partner, if applicable
- Assessment of your fallopian tubes to confirm they are open
These investigations help determine whether ovulation induction is the most appropriate treatment.
Step 2: Fertility medication
Ovulation induction usually begins early in your menstrual cycle.
The medications most commonly used include:
Letrozole
Often considered the first-line treatment for women with PCOS, letrozole encourages the ovaries to develop a mature follicle and has become one of the most widely prescribed medications for ovulation induction.
Clomiphene citrate (Clomid®)
Clomiphene has been used successfully for many years and works by encouraging the brain to release hormones that stimulate ovulation.
Gonadotrophin injections
If tablets are unsuccessful, injectable fertility hormones may be recommended. These require closer monitoring because they can stimulate multiple follicles.
Your fertility specialist will recommend the medication that best suits your individual circumstances.
Step 3: Monitoring
During treatment, you’ll usually have one or more ultrasounds to measure the size of your developing follicles.and blood tests are also used to monitor hormone levels.
Monitoring allows your fertility team to determine:
- Whether the medication is working
- When ovulation is likely to occur
- Whether the cycle should continue safely
If too many follicles develop, your doctor may recommend cancelling the cycle to reduce the risk of twins or higher-order multiple pregnancies.
Step 4: Timing intercourse or IUI
Once a mature follicle is ready, your doctor may advise:
- Timed intercourse over the next few days
- A trigger injection to help release the egg
- Intrauterine insemination (IUI), depending on your treatment plan
Carefully timing ovulation gives sperm the best opportunity to meet the egg.
How successful is ovulation induction?
Success depends on several factors, including:
- Your age
- The underlying cause of infertility
- Egg quality
- Sperm quality
- Your overall health
Many women ovulate successfully within the first few treatment cycles, but pregnancy may still take time.
It’s important to remember that successful ovulation does not always result in pregnancy immediately. Sometimes several cycles are needed.
Are there any risks?
Ovulation induction is generally very safe when supervised by a fertility specialist.
Potential risks include:
Multiple pregnancy
If more than one egg is released, there is an increased chance of twins or, less commonly, higher-order multiples.
Regular monitoring helps minimise this risk.
Ovarian hyperstimulation syndrome (OHSS)
This occurs when the ovaries respond too strongly to medication. It is uncommon with oral medications such as letrozole and clomiphene but is more likely with injectable hormones.
Your fertility team carefully monitors treatment to reduce this risk.
Side effects
Depending on the medication used, some women experience:
- Hot flushes
- Headaches
- Mood changes
- Breast tenderness
- Mild bloating
- Fatigue
These symptoms are usually temporary and settle once the cycle is complete.
Looking after yourself during treatment
Ovulation induction often feels less overwhelming than IVF, but it can still bring emotional highs and lows.
It can help to:
- Take medications exactly as prescribed.
- Attend all monitoring appointments.
- Maintain a balanced diet and regular exercise.
- Prioritise sleep and stress management.
- Avoid comparing your journey with others.
- Ask questions whenever you’re unsure.
Remember, every cycle provides valuable information that helps guide future treatment.
