1. What is IUI EDD Calculation?

The IUI EDD (Intrauterine Insemination Estimated Due Date) calculation determines the expected delivery date following an IUI procedure. It adds 266 days (38 weeks) to the IUI date, representing the typical gestation period from conception.

2. How Does the Calculator Work?

The calculator uses the standard IUI EDD formula:

Where:

• \( IUI\ Date \) — Date of intrauterine insemination procedure
• \( 266\ days \) — Standard gestation period from conception
• \( IUI\ EDD \) — Estimated due date

Explanation: This calculation assumes a standard 38-week gestation period from the date of conception (IUI procedure) to estimated delivery.

3. Importance of IUI EDD Calculation

Details: Accurate due date calculation is crucial for proper prenatal care scheduling, fetal development monitoring, and delivery planning. It helps healthcare providers track pregnancy milestones and ensure optimal maternal and fetal health.

4. Using the Calculator

Tips: Enter the exact date of your IUI procedure. The calculator will automatically compute your estimated due date by adding 266 days (38 weeks) to the IUI date.

5. Frequently Asked Questions (FAQ)

Q1: Why 266 days instead of 280 days?
A: 280 days (40 weeks) is calculated from the first day of the last menstrual period (LMP), while 266 days (38 weeks) is calculated from the actual conception date (IUI procedure).

Q2: How accurate is the IUI EDD calculation?
A: IUI EDD calculation is very accurate since the conception date is precisely known. This method is more reliable than LMP-based calculations.

Q3: Can the due date change after ultrasound?
A: Early pregnancy ultrasound may adjust the due date slightly, but for IUI pregnancies, the calculated EDD is typically very accurate and rarely requires significant adjustment.

Q4: What if I had multiple IUI procedures?
A: Use the date of the successful IUI procedure that resulted in pregnancy. If uncertain, consult with your healthcare provider.

Q5: Does this work for IVF pregnancies too?
A: For IVF, the calculation differs slightly depending on whether it was a 3-day or 5-day embryo transfer. IUI calculation is specific to intrauterine insemination procedures.
