Induction of Ovulation

For many women, difficulty conceiving is linked to problems with ovulation — either irregular or absent egg release. Induction of ovulation is a treatment designed to help stimulate the ovaries and encourage regular egg production.

Induction of ovulation is a simple yet effective fertility treatment that can help many women achieve pregnancy safely under expert supervision.

What is Ovulation Induction?

Ovulation induction uses medication to stimulate the ovaries so that one or more eggs develop and are released. This increases the chances of natural conception in two important ways:

  1. Increasing the chances that ovulation is taking place

  2. Helping to accurately time sexual activity for the best chance of fertilisation

Ultrasound Follicular Tracking

What is it?

Follicular tracking is a series of ultrasound scans used to monitor the growth and development of follicles (the fluid-filled sacs in the ovaries that contain eggs).

Why is it done?

  • To confirm if ovulation is happening.

  • To assess the best time for intercourse .

  • To monitor response to fertility medications (e.g., clomiphene or letrozole).

  • To avoid overstimulation and reduce the risk of multiple pregnancies.

How is it performed?

  • Usually done by transvaginal ultrasound.

  • Multiple scans are carried out during the menstrual cycle (starting around day 10–12).

  • The size of the leading follicle(s) is measured until it reaches maturity (about 18–22 mm).

  • The endometrium (womb lining) is also assessed for thickness and quality.

What happens next?

When a follicle is ready, an ovulation trigger injection may be given, or couples may be advised to have intercourse at the right time.

  • If no follicle develops, the medication for the next cycle might be increased.

Risks and Considerations

  • Multiple pregnancy (twins or more) is slightly increased.

  • Ovarian hyperstimulation (rare but possible with injections).

How is it Done?

  1. Medication – tablets (e.g., clomiphene citrate, letrozole) or injectable hormones (gonadotrophins) are prescribed.

  2. Monitoring – ultrasound scans and blood tests are used to track follicle growth and hormone levels.

  3. Timing – when a mature egg is ready, ovulation is triggered with an injection, and timed intercourse or IUI can be planned.

Who is it For?

Ovulation induction may be recommended for women who have:

  • Irregular or absent periods (anovulation)

  • Polycystic ovary syndrome (PCOS)

  • Hormonal imbalances affecting egg release

  • Unexplained infertility (in selected cases)
