Ovulation Induction
Ovulation Induction (OI)
Gently encouraging your body to release the egg it needs.
What is Ovulation Induction (OI)?
Ovulation Induction (OI) uses low-dose hormonal medications to stimulate the development and release of one or two mature eggs in women who do not ovulate regularly or at all. It is one of the simplest and most cost-effective fertility treatments available. At Ova IVF, OI is carefully monitored with serial ultrasound scans to maximise efficacy and minimise the risk of multiple pregnancy.
Who is this for?
- Women with polycystic ovary syndrome (PCOS)
- Women with hypothalamic amenorrhoea (absent periods)
- Women with irregular or infrequent ovulation (oligovulation)
- Women with unexplained infertility as a first-line treatment
- Couples undergoing IUI (OI is combined with IUI)
- Women with WHO Group I or II anovulation
Key Benefits
Step-by-Step Procedure
A clear, transparent walkthrough of every stage of your Ovulation Induction treatment at Ova IVF.
Baseline Assessment
Day 2–3 hormonal blood tests (FSH, LH, oestradiol, AMH) and transvaginal ultrasound assess ovarian reserve and baseline status before starting medication.
Medication Prescription
Oral agents (clomiphene citrate or letrozole) or low-dose injectable gonadotropins are prescribed based on your diagnosis and ovarian reserve. Letrozole is preferred for PCOS.
Follicle Monitoring
Serial transvaginal ultrasound scans (typically on Days 10, 12, and 14) track follicle growth. The aim is to develop 1–2 dominant follicles of 18–20mm.
Trigger Injection (if required)
If natural LH surge is not detected, a trigger injection (hCG) is given to induce final egg maturation and time ovulation precisely.
Timed Intercourse or IUI
Couples are advised to have timed intercourse 24–36 hours after the trigger, or IUI is performed if indicated.
Luteal Phase Support
Progesterone supplementation may be prescribed to support the luteal phase and early implantation.
Pregnancy Test
A blood beta-hCG test is performed 14 days after ovulation to confirm pregnancy.
Frequently Asked Questions
How many cycles of ovulation induction should I try?
Most specialists recommend 3–6 cycles. If pregnancy has not occurred after 6 monitored cycles, progression to IUI or IVF is usually recommended.
What is the risk of twins with ovulation induction?
With careful monitoring and single-follicle development, the risk of twins is low (5–10%). Our team adjusts medication doses to minimise this risk.
Is ovulation induction suitable for PCOS?
Yes. Letrozole is the first-line agent for PCOS-related anovulation and has a lower risk of multiple pregnancy than clomiphene citrate.
