An hCG injection is given in the morning on the day when at least one follicle has reached 17 mm in mean diameter.
Timing of hCG Injection in IUI
In Intrauterine Insemination (IUI) procedures, the timing of the hCG injection is crucial for optimal results. Here's a breakdown based on the provided reference:
- Follicle Size: The hCG injection (5000 IU) is administered when at least one follicle measures 17 mm in mean diameter.
- Time of Day: The injection is typically given in the morning.
- IUI Timing: IUI is performed the next day, approximately 24-32 hours after the hCG injection. This allows for ovulation to occur.
The timing of the hCG injection is carefully planned to coincide with optimal follicular maturity, ensuring that the egg is released at the right time for fertilization.
