Oral Ovulation Induction (OI) – Stimulating Natural Conception
Ovulation induction uses medicines to stimulate the ovaries to grow and release eggs - especially helpful for women who don't ovulate regularly, such as those with PCOS. Medications like clomiphene citrate or letrozole are started early in the cycle and egg growth is monitored through ultrasound.

Who Is It For?
- Women with irregular or absent periods (anovulation)

How It Works
Baseline Assessment
Blood tests and ultrasound on day 2–3 of the menstrual cycle to check hormone levels and ovarian status
Medication
Oral tablets (letrozole or clomiphene) taken for 5 days early in the cycle to stimulate egg development
Follicle Monitoring
Serial ultrasound scans to track follicle growth and endometrial lining
Trigger & Timing
Once follicles reach optimal size, a trigger injection may be given to time ovulation; timed intercourse or IUI follows
