When journalist Anna De Souza was in her early 30s, she asked her ob-gyn when she should start thinking about children. “When you were 26,” the doctor replied. The comment surprised her—she knew fertility declined with age, but not how quickly. Looking back, she wishes her high school sex-ed class had taught more than just how to avoid pregnancy. At 36, she gave birth to twins after two rounds of IVF, later welcoming another child through the same treatment. If she’d had more knowledge earlier, she says she might have tried the “fun way” first, instead of the “needles way.”
The fertility knowledge gap
De Souza is not alone. Reproductive endocrinologists say many patients arrive at clinics with serious misconceptions about fertility. Michael Zinaman, MD, of New York, said, “It’s been stunning how ill-informed so many people are.”
Some common gaps in understanding include:
- Fertility is highest in a woman’s 20s and declines with age.
- Being underweight, overweight, or having untreated STIs can reduce fertility.
- Prenatal vitamins with folic acid are recommended even before pregnancy.
- Men’s lifestyle choices, like smoking or heavy drinking, can harm sperm quality.
- IVF success rates are often lower than many people assume.
What the research shows
Studies confirm that many women lack fertility knowledge:
- A 2023 survey of nearly 1,800 women ages 18–29 found only 59% knew when in the menstrual cycle pregnancy is most likely.
- A 2016 study found just over half of women knew what ovulation meant, and fewer than a third knew when it occurs.
- Even medical trainees answered only about two-thirds of fertility questions correctly in a 2017 study.
This knowledge gap has real consequences, often delaying family planning or leading to disappointment when conception takes longer than expected.
Why sex education matters
Experts argue that fertility education should be a standard part of sex ed, covering not only pregnancy prevention but also how to conceive. Rashmi Kudesia, MD, of Houston, explained, “People think if age is a concern, my doctor will bring it up. And that’s definitely not a fair assumption.”
Some states are moving toward stronger fertility education. California passed a “Know Your Period” law requiring schools to teach students about the menstrual cycle and menopause. About 500 school districts use a curriculum that includes lessons on ovulation and fertility. Still, these programs often face political and cultural pushback.
The bottom line
Fertility education is not about pushing people to have children sooner—it’s about giving them accurate information so they can make informed decisions. As Kudesia puts it, misunderstanding fertility can mean losing valuable time and missing the chance to have the family size one hopes for.
Young people, too, are asking for better information. As one California student who advocated for reproductive education explained, it gives teens a safe place to learn about their bodies without stigma or shame.
Key takeaways for readers
- Fertility declines significantly after age 30, more steeply after 35.
- IVF can help, but success rates vary and are not guaranteed.
- Both men and women’s lifestyle factors play a role in fertility.
- Understanding ovulation and menstrual cycles is essential for conception.
- Better fertility education can empower people to make informed family-planning choices
