The Fertility Conversation You Should Have Had a Decade Ago

In 1984 the average age of a first-time mother in the United States was 19. Last year it was 30. The female reproductive system was designed 300,000 years ago for women who didn’t live past 25. It has not changed since and almost nobody is telling women this clearly enough or early enough to actually do something about it.

I sat down with Dr. Jamie Grifo, Director of Reproductive Endocrinology at NYU Langone and one of the pioneers of IVF, and what he told me is the conversation every woman deserved to have in her 20s.

The biology nobody taught us

You were born as a fetus with 7 million eggs. By birth you had 1 million. By puberty 300,000. Every month your body selects 500 eggs, grows them, and ovulates one. The other 499 are discarded. By 42 you are largely out of good quality eggs.

Fertility starts declining measurably at 25. Not 35. Not 40. 25. By 37 there is a real drop. By 40 another significant one. A 40-year-old woman has roughly a 2 to 3% natural pregnancy rate per month. Most women find this out when they are already struggling.

The question he gets asked every day

What did I do wrong?

That is what Dr. Grifo’s patients ask him. Women who were never told any of this, who assumed it would work when they were ready because nobody said otherwise.

His answer is always the same. Nothing. You were never in control of your fertility. The only thing you were ever in control of was when you tried and with whom. That is it. The biology is 300,000 years old and it was not designed for women starting families at 37.

And 40% of infertility cases have a male factor component. Yet the entire cultural narrative has been placed on women.

What to do if you are not ready yet

Freeze your eggs. Dr. Grifo started the first egg freezing program at NYU in 1999 because he kept watching patients arrive in their late 30s with no information and narrowing options. His oldest patient to deliver using frozen eggs froze them in 2010 and delivered at 54.

Eggs versus embryos matters. An egg contains only your DNA. An embryo has been fertilized and can be tested for chromosomal health before implantation. If you know whose sperm you want to use, freezing embryos is often a stronger option. If you are single, freeze eggs first.

One thing most people do not know: even young healthy women produce chromosomally abnormal embryos more than half the time. The system was designed for inefficiency. This is not a personal failing, it is just biology.

The tests to ask for now

On day two of your cycle ask for three things. FSH and estradiol together tell you about egg quality. AMH tells you about egg quantity. These are simple blood draws. Most women have never had them because nobody ordered them.

On endometriosis and PCOS

75% of women with stage 3 or 4 endometriosis will need IVF to conceive. Most spent years being told their debilitating period pain was just a bad period. If you cannot get through your period without missing work or activities that is not normal and it deserves investigation.

PCOS is not a disease. It is an altered hormonal pattern with real treatment options. Diet, insulin management, and medication restore ovulation for many women. GLP-1 medications are now triggering ovulation in PCOS patients who were not ovulating before which is where the Ozempic baby conversation actually comes from.

Get a consultation with a reproductive endocrinologist in your 30s even if you are not trying yet. Learn your numbers, understand where you are on the curve, and make decisions from real information rather than from a cultural myth that it will work when you are ready.

You were never in control of your fertility, but you can be in control of how informed you are.
