To determine the ovarian score, we must understand the terms used in obstetrics: "G" stands for Gravida (the number of times a woman has been pregnant) and "P" stands for Para (the number of pregnancies that have progressed past 20 weeks, resulting in a birth, regardless of the outcome).
Here, the patient is a 36-week pregnant lady with a previous twin delivery:
- Current pregnancy counts as one, making her a gravida of 2 (G2).
- A single birthing event of twins is counted as one para, making her a para of 1 (P1).
Combining these, the ovarian score is G2P1.
