The sperm lifespan is under 90 days, meaning a single decision to change your life right the second for a man will give us completely new sperm three months from now.

We can get the biggest bang for our buck by having your male partner start to take their own health and fertility seriously before you're on your trying to conceive journey.

That's a great question.

You know, men and women both have kind of two things that we want to think about.

There's the production of sperm, which is a hormonally derived process, very similar to how women ovulate, meaning the brain sends out hormones to the testes, and then the testes are told to make both sperm and testosterone at the same time.

So number one is that this pathway can be interrupted.

So one of the top things I see in clinical practice is going to be men who are using exogenous testosterone.

Maybe they go to a men's health clinic or they have low libido or fatigue or they're gaining weight and they're put on testosterone and they can feel better.

But when the male's brain sees testosterone, it assumes sperm is being made at the same time.

So it shuts off the production of FSH and LH, those hormones to drive testosterone and sperm.

So a man who's using testosterone will stop making sperm.

And sometimes that can be irreversible.

irreversible.

Now, oftentimes it can come back, but it can take months.

As we said, we have to generate new sperm.

And this is why something that is readily given out, men can get testosterone from apps now.

They don't even have to go to a doctor.

They're sometimes giving testosterone without having labs checked or semen analysis.

Really done in the wrong way can be detrimental.
