Fertility does change with age, but it doesn’t fall off an abrupt ledge the moment someone turns 35.
In fact, recent population data show that birth rates for people ages 35-39 have remained steady, and births for individuals over 40 have actually increased 💪🏻💪🏻.
Part of this rise reflects advances in assisted reproductive technologies, including IVF, which allow many people to conceive later in life.
According to the American College of Obstetricians and Gynecologists (ACOG):
🍍Healthy couples in their 20s to early 30s, the chance of conception in any menstrual cycle is 25-30%
🍍By age 40, the chance of conceiving in a given cycle is under 10%
These numbers reflect averages. Not destinies. Ovarian reserve, cycle regularity, partner fertility, reproductive history, lifestyle factors, and underlying medical conditions all shape the path far more than a single birthday could.
Your fertility journey is uniquely yours. Age is just one chapter in a much larger story. If you’re starting to think about timing, testing, or treatment options, we’re here to guide you with evidence based recommendations, clarity, and care - every step of the way.
