Case studies

The Evidence

Most products in this category open with a transformation story. We do not have one yet, and we are not going to write one. What we do have is the published literature the whole product is built on — design, sample size and result, one study at a time.

STUDY 01

Trains · Endurance

Aerobic training improves erectile function^[4]

Design: Meta-analysis of randomised controlled trials
Sample: 11 RCTs · n = 1,147
Result: +2.8 IIEF-EF points

Supervised aerobic training produced a clinically meaningful improvement in erectile function score with no drug involved. This is the strongest single result in the field, and it is why endurance is programmed first.

STUDY 02

Trains · Control

Pelvic floor muscle training for erectile difficulty and early ejaculation^[3]

Design: Systematic review
Sample: 10 trials
Result: Improvement in both outcomes; no optimal protocol identified

Pelvic floor training works, and the literature is candid that nobody has established the right dose. We program contraction, speed and — the part most protocols omit — the eccentric release, and we say plainly that the protocol is our reasoning, not a settled standard.

STUDY 03

Trains · Session Quality

Energy expenditure during sexual activity in young healthy couples^[2]

Design: Field measurement with accelerometry, in participants' own homes
Sample: 21 couples · mean session 24.7 min
Result: Men 6.0 METs / 101 ± 52 kcal · Women 5.6 METs / 69.1 ± 25.6 kcal

The untrained average sits exactly on the CDC's 6.0-MET vigorous threshold. That single number is the product: which side of the line a session lands on is trainable, and vigorous minutes count double toward the weekly target.

STUDY 04

Trains · Context

Prevalence and diagnosis of erectile difficulty in US men^[5]

Design: Population survey
Sample: n = 1,822
Result: 24.2% meet criteria · 7.7% ever formally diagnosed

The gap between prevalence and diagnosis is the market and the motivation. Most men in this group will never see a clinician about it, and training is something they can start without one.

STUDY 05

Trains · Context

Global prevalence of female sexual difficulty^[6]

Design: Systematic review and meta-analysis
Sample: 18 studies · n = 36,777
Result: 47.8% pooled prevalence · 50.4% reporting sexual distress

Roughly half. Any product that treats this as a men's category is ignoring most of the affected population, which is why reference ranges, progressions and the Postpartum Rebuild block are built for women from the start.

Member case studies will be added once the closed beta produces real PQ-movement data. Until then this page contains no member story, no before-and-after and no outcome we have not cited.

Member results

We will publish results when we have results.

iSexercise is pre-launch. Member outcomes and testimonials publish after the closed beta, and they will be real PQ movement from real members — never a written-up quote. Until then, the only claims on this site are the cited ones.
