CONTRACEPTIVE BOXER BRIEFS 37.1
DESCRIPTION
The 37.1 contraceptive boxer brief is a contraceptive medical device currently under development.
As an everyday, elegant, and functional contraceptive undergarment, the 37.1 contraceptive boxer brief will be an essential item in every man's wardrobe. A reliable alternative to classic contraceptive solutions, it will ensure thermal contraception through testicular ascent (TTCD) — a natural, reversible, non-invasive, and hormone-free method.
A sleek appearance, a clean, contemporary design, discreet and ingenious technology. The 37.1 boxer brief will feature a transversal pouch facilitating the daily movements of TTCD: it will be put on in a few seconds. Inside, a soft, plush, and adjustable annular structure will ensure the testicles are kept warm in the body, at 37°C.
The precise and quick adjustment system will allow the boxer brief to be easily adjusted at any time of the day. It will adapt to your body shape and follow your every movement. On the outside, a wide elastic waistband will guarantee optimal comfort.
Carefully selected materials, an ergonomic cut, and high-end finishes will make it an ideal everyday companion designed to combine comfort, effectiveness, and style
RESEARCH
The 37.1 contraceptive boxer will go through several design phases: sketching, modeling, mock-ups, prototypes, fittings, and sizing. Numerous back-and-forth exchanges between pattern makers, manufacturers, and testers will be necessary to arrive at the final version.
Next, the 37.1 contraceptive boxer will have to undergo pre-clinical trials (biocompatibility, durability, suitability for use) and clinical trials (safety and efficacy study on testers) before being marketed.
PRINCIPLE
The 37.1 contraceptive boxer shorts from 37 degrees ensure thermal contraception by testicular ascent. They mechanically lift and hold the testicles above the scrotum. Their temperature then rises and approaches that of the rest of the body: 37 °C. At this temperature, the sperm production function is impaired, and fertility decreases.
If this action is performed daily, fertility decreases sufficiently to achieve contraception.

THE MEDICAL CERTIFICATION PROCESS
ISO 13485 STANDARD
ISO 13485 is the international reference standard for medical devices.
It frames our entire quality management system, from design to production, including controls and traceability.
This standard ensures that each stage of our product development meets strict requirements for safety, reliability, and regulatory compliance.
PRECLINICAL TRIALS
Before any human evaluation, the device undergoes thorough preclinical trials.
These tests specifically aim to verify the biocompatibility of the materials used, in order to rule out any risk of irritation or allergic reaction.
They also make it possible to validate the device's performance and its long-term durability by simulating real-world usage conditions.
CLINICAL TRIALS
The aim of clinical trials is to demonstrate the safety, efficacy, and actual benefit of the device in real-world use.
We have already designed the protocol for a clinical study for the 37.1 boxer, and the launch of this study is planned for 2027, subject to the necessary authorizations.
CE MARKING
CE marking is issued by an independent notified body responsible for evaluating the device's entire technical file.
This file notably includes elements related to the quality system, pre-clinical tests, and clinical data.
Following this evaluation, the notified body certifies that the device complies with European requirements and can be used safely, with a demonstrated level of performance.
