Men need to understand, the average age of the father has gone up about three and a half years. And with that, the chance of problems with the child also can increase, and that pregnancy becomes a lot riskier.
And this is why.

Dr. Michael Eisenberg is an expert in male sexual function and fertility who's helping us to learn the truth about optimal sexual health.

If you just look at all the data, sperm counts are declining, but low sperm counts and low testosterone could have devastating effects. For example, men with lower semen quality have higher risk of death.

**Steven Bartlett** (0:30)
Wow.

**Michael Eisenberg** (0:30)
There's a lot of really interesting questions that need to be answered.

**Steven Bartlett** (0:33)
Okay, let's get into that. Is there any evidence that the chemicals in our environment are impacting our sperm count and our testosterone levels?

**SPEAKER_2** (0:39)
Yes.

**Michael Eisenberg** (0:40)
It's a chemical that's in a lot of creams and lotions that we use. And then there's a chemical that's used in the manufacture of plastic. And that could have pretty devastating effects. And so don't drink out of plastic water bottles.

What about hair loss? Couldn't figure out if low testosterone or high testosterone causes a receding hairline.

**Michael Eisenberg** (0:55)
Most men are not going to like this, but it turns out that...

**Steven Bartlett** (0:57)
If I'm sat down all day, is that going to have an impact on my sperm count?

**Michael Eisenberg** (1:01)
There are studies that do support that. I would say take breaks, stand up to try and air out the area.

**Steven Bartlett** (1:05)
What can I do to give myself the best possible chance of increasing my fertility?

**Michael Eisenberg** (1:10)
So there's a lot that we can do. And usually we start with...

**Steven Bartlett** (1:13)
And then erectile dysfunction.

**Michael Eisenberg** (1:14)
Hundreds of millions of men all over the world have trouble with erections. But as long as you have a penis, we can always make it hard. For example, we can teach men to give themselves...

**Steven Bartlett** (1:22)
Oh, I just got a shiver down my body.

**Michael Eisenberg** (1:25)
But it probably works 80 to 90% of the time.

**Steven Bartlett** (1:29)

Dr. Michael Eisenberg, why do you do what you do and what you do?

**Michael Eisenberg** (2:08)
It's a pleasure to be here, certainly an honor. I kind of see myself as a researcher and advocate for men's health, men's reproductive health, sexual health. And so, you know, I think when I see patients in clinic, that's what I'm trying to do, to try and understand where they're coming from, any issues they have and find out ways that we can, you know, work and improve them together. And certainly from my research perspective, I always want to, you know, try and define what the issues are and just improve our treatments that we have for men. I am the director of male reproductive and sexual health at Stanford, or men's health, in the department of urology.
I have a joint appointment in the department of obstetrics and gynecology because fertility is a team sport. And so I also help, you know, couples and I refer women to the female side, just like I, you know, get lots of referrals from them, you know, when we're kind of worried about the male partner.

**Steven Bartlett** (2:58)
When you say sort of reproductive health, what are all the sort of things that fall within that bucket or underneath that umbrella?

**Michael Eisenberg** (3:05)
So I think, you know, reproductive health really, I mean, I guess is it's sort of name applies would be, you know, trying to have a baby. But I think it's so much more than that because I think what we're really learning is that, you know, fertility is kind of a window into future health. Probably about 10% of the male genome is devoted to reproduction. And given there's only about 25,000 genes in the body, you know, it makes sense that some genes that are operating in reproduction also operate in another organ system. There was a study done where they took biopsies of men that had trouble making sperm and tried to sort of replicate these cells. And they found that these cells had very high rates of mutations in their DNA. So you can imagine, you know, sort of for checks and balances when we're making sperm, it makes sense if you can't sort of faithfully replicate your DNA. You know, there's probably not, there's probably going to be some blocks where you can't make a sperm, right? If there's going to be mutations. But also, these men may be set up for other problems, right, like cancers or something like that. If, you know, the body can't, you know, effectively replicate cells or DNA. There could also be sort of hormonal links. And that's another thing that we commonly look at when we're evaluating men with infertility.
