Erectile dysfunction
Eisenberg describes erectile problems as a 'check engine light' for overall health that warrants evaluation.
“this can be like a check engine light. Right. That if erections are not as good, it's not just a convenience issue”

Eisenberg says penile injections work about 90% of the time despite a large psychological barrier.

Testosterone replacement therapy
Eisenberg says most men are started on testosterone as a trial and can stop if they see no benefit after six months to a year.
“So after six months, after a year, they're not seeing those improvements, then we can stop it”

Eisenberg argues that men with normal testosterone gain little from supplementation and criticizes clinics that prescribe it for profit.

Eisenberg explains that exogenous testosterone reliably suppresses sperm production and has been tested as a male contraceptive.
“Testosterone has been tested by the World Health Organization as a contraceptive. So it can actually lower sperm production”

Hypogonadism
Eisenberg recommends adding a testosterone test to routine checkups starting around age 40 to 50, or earlier with risk factors.
“getting checked, I think, sooner rather than later is a reasonable thing to do. probably starting maybe 40, 50”

Eisenberg says testosterone peaks between ages 20 and 30 and then declines about 1% a year.

Benign prostatic hyperplasia
Eisenberg says waking once a night to urinate is normal but two or more times warrants evaluation.
“once a night is pretty normal. But when it starts to be a little more disruptive two, three, four times, I think definitely you want to get evaluated”

Male infertility
Eisenberg argues that a male factor is present in about half of infertility cases yet men are often never evaluated before couples move to IVF.
“In this country, probably a third of the time, a mail's never seen by a specialist, never checked, bypassed to go through IVF”

Decline in sperm counts
Eisenberg says sperm counts are declining worldwide and the decline appears to be accelerating, alongside other signs of worsening male reproductive health.
“the data suggests that it's accelerating in the last probably 20 years. We also see declines in testosterone levels”

Prostate cancer

GLP-1 receptor agonists
Eisenberg says weight loss by any means, including GLP-1 drugs and bariatric surgery, can raise testosterone.
