The correct answer, , indicates that approximately 10-15% of couples of reproductive age experience infertility. This range is widely accepted in medical literature and reflects the prevalence of couples facing difficulties in conceiving. Factors contributing to infertility can include issues with ovulation, sperm quality, tubal patency, and uterine or cervical factors.
## Why Each Wrong Option is Incorrect

- **Option B:** is closer but still underestimates the commonly cited range for the incidence of infertility.
- **Option D:** overestimates the commonly reported incidence of infertility. While it's true that a significant portion of couples may experience difficulty conceiving at some point, exceeds the widely accepted range.
## Clinical Pearl / High-Yield Fact
A key point to remember is that infertility affects about 1 in 6 couples (or roughly 10-15%), and the causes can be attributed to male factors (40-50%), female factors (40-50%), or a combination of both (10-30%). This highlights the importance of evaluating both partners when assessing infertility.
