Female Fertility: What You Should Know About Age, Ovarian Reserve, and Testing
Female fertility doesn't drop off a cliff at one magic age — it's a gradual process whose pace can now be described fairly precisely using data from real fertility-clinic registries and cohort studies. We look at what the actual age-related fertility decline curve looks like, what an AMH/ovarian reserve test actually tells you (and what it doesn't), which factors are genuinely modifiable, and when it's worth seeing a fertility specialist instead of waiting longer.
