Eisenberg describes a repeatable starting workup for male fertility rather than jumping directly to assisted reproduction or assuming the issue lies with the woman. The process begins with overall health, medical conditions, surgery, medication, exercise, and heat exposures. A clinician then performs an examination and orders a semen analysis covering volume, sperm count, movement, and shape. Testosterone and other hormones involved in reproductive signaling add another layer because the testicles produce both sperm and testosterone. The findings are interpreted alongside an evaluation of the other partner, then used to discuss the likelihood of conception and possible next actions. Eisenberg says a male factor contributes in roughly half of infertility cases, while noting that many men are never evaluated. The framework is therefore a clinical assessment pathway, not a home checklist that produces a diagnosis.
Origin
Eisenberg lays out the baseline process he uses when a man asks how to maximize his chance of having children.
Core principles
- 01Fertility evaluation should include the male partner rather than defaulting to the woman
- 02Medical history and reversible exposures can change the next step
- 03Semen quality has several dimensions, not one score
- 04Sperm production and testosterone belong to the same testicular system
- 05Fertility is a couple-level process
How to run it
- 1
Map health and exposures
Review medical conditions, prior surgery, medication, exercise, sauna or hot-tub use, and other plausible reproductive risks with a clinician. The purpose is to identify context and potentially reversible contributors.
Pro tip Bring a complete medication and supplement list rather than relying on memory.
Watch out Do not stop prescribed medicine without the prescriber's guidance.
- 2
Complete the examination
Have a qualified clinician assess testicular size and whether the relevant structures appear to be in place. This adds information that history alone cannot provide.
Watch out A self-examination cannot replace a clinical fertility examination.
- 3
Measure semen quality
Use a semen analysis to assess volume, sperm count, movement, and shape. Treat these as separate measurements rather than collapsing fertility into one number.
Pro tip Ask the clinician how collection conditions and repeat testing affect interpretation.
Watch out One result should be interpreted in clinical context rather than used for self-diagnosis.
- 4
Check the hormonal axis
Measure testosterone and other hormones involved in reproductive signaling when the clinician considers them appropriate. Use the pattern to inform, not independently dictate, the next step.
Watch out The transcript does not provide a complete laboratory interpretation protocol.
- 5
Evaluate the couple
Arrange an appropriate evaluation of the other partner and review both sets of findings together. Discuss treatment or timing only after considering the couple-level picture.
Pro tip Ask whether any identified male risk is reversible before escalating treatment.
Watch out Infertility should not automatically be attributed to either partner.
In the wild
Eisenberg describes couples reaching IVF without the man being evaluated. A structured male assessment can reveal a medication or repeated heat exposure that may be contributing and deserves clinical review before the couple assumes no reversible factor exists.
→ The couple gains a fuller explanation and a clinician-led opportunity to address a possible contributor.
Common mistakes
Evaluating only the woman
Eisenberg calls this a major misconception because he says a male factor contributes in about half of cases.
Treating sperm count as the whole result
His baseline analysis also considers volume, movement, shape, hormones, history, and examination findings.
Changing medication alone
Medication may matter, but any change needs the prescribing clinician's involvement.
Is it for you?
Best for
It is best for couples planning children or struggling to conceive who want a clinician-led baseline assessment.
Not ideal for
It is not a self-diagnosis tool or a substitute for urgent care, specialist interpretation, or evaluation of the female partner.
From the transcript
“one of the basic evaluations will be a seman analysis”
“fertility is a team sport”
“probably about half the time there's a male Factor contributing”
