male contraceptive

Product and method boundary

Record the physical referent separately from the activity or regimen through which it is used.

1. What physical product or substance does this entry denote? definition
2. Which associated procedures, behaviours or regimens require links to neighbouring models? boundary

Intended use basis

Identify evidence that pregnancy prevention is an intended function rather than an incidental fertility effect.

1. Which source establishes a contraceptive purpose for this product or substance? provenance
2. What anatomical application or administration makes it a male contraceptive within this entry's scope? boundary

Mechanism chain

Record the proposed or demonstrated chain from deployment to prevention of conception.

1. Does the contraceptive exclude sperm, alter production or function, obstruct transport, or act through another documented mechanism? definition
2. Which parts of the mechanism are demonstrated, and which remain hypotheses? provenance

Protection conditions

Record timing and verification requirements without assuming that application or administration immediately establishes protection.

1. What elapsed time, deployment condition or verification endpoint establishes the claimed onset of protection? measurement
2. What events end or interrupt protection, and what documented action is required before protection can be relied upon again? action

Effectiveness endpoints

Distinguish pregnancy outcomes from surrogate measures and preserve the denominator and observation period.

1. Is the reported endpoint pregnancy, sperm concentration, sperm function, barrier integrity or another measure? measurement
2. What population, exposure denominator, observation period and use conditions accompany the result? measurement
3. What evidence supports translating any surrogate endpoint into a contraceptive protection claim? provenance

Dated claim status

Associate each availability or authorisation claim with a specific product, jurisdiction and date.

1. Which dated study records or regulatory documents support this product's claimed status? provenance
2. Does that status apply to this exact formulation, device configuration and intended use? boundary

Deployment dependencies

Record applicable fitting, administration, placement and maintenance requirements from product-specific instructions.

1. Which fit, dose, route, placement or timing requirements are necessary for the documented contraceptive effect? measurement
2. Which steps may the user perform, and which require a qualified practitioner or study team? action

Modality-specific failure

Select applicable failure modes, such as barrier damage or slippage, degraded formulation, missed administration or device displacement.

1. Which storage limits, expiry conditions, material incompatibilities or deployment failures are documented for this modality? provenance
2. Which observations warrant replacement, interrupted reliance or referral under the applicable instructions? action

User and partner effects

Identify documented adverse effects, exposure pathways and restrictions relevant to the user or partner.

1. What local, systemic, sexual-function or partner-exposure effects have been investigated for this modality? provenance
2. Which documented conditions or interactions restrict use or require clinical assessment? action

Infection protection boundary

Keep infection protection claims distinct from contraceptive performance.

1. Is protection against any specified sexually transmitted infection claimed for this exact product and use? boundary
2. What evidence supports the claimed infection protection and its limitations? provenance

Reversibility pathway

Record whether recovery requires cessation, removal or another intervention, and which recovery outcomes have actually been observed.

1. What documented steps end use or remove the contraceptive, and who can perform them? action
2. Which endpoint demonstrates recovery, over what follow-up period, and with what uncertainty or incomplete recovery? measurement
