  • Phase I human clinical trials underway

Experimental and employed in the process of certification

The thermal method

  • to wear 15 hours a day, 7 days a week

The Drenche

Contraceptive equity, a taboo subject.

In France, contraception in couples currently relies solely on women in 2/3 of cases (Le Guen et al 2017). Some women find it hard to cope with their contraceptive methods, others remark on the mental load concerning the lack of choice women have regarding contraception. It is high time this changed!

In 2022, it is still not officially possible for men to use the male thermal contraceptive method through testicular lifting, even though it is natural, safe, effective and reversible. However, both internationally and in France, a majority of men are ready to use a male contraceptive method (Heinemann et al. 2005).  

Methods exist and are reliable, but their distribution is limited for two major reasons:

  1. A general lack of knowledge
  2. Lack of training of the medical population involved in contraceptive prescribing (Mieusset et al. 2022 - Travers and Wanda 2022).

Male thermal contraception.

Since the 1990s, the thermal method has been available.

It is based on the temperature dependence of spermatogenesis. It has been clinically demonstrated that the thermal contraceptive method meets the criteria of official contraceptive methods: effectiveness, reversibility, absence of side effects and acceptability. Environmental, social and economic criteria are also important in the choice of contraceptive modalities. See the studies

Thermal male contraception is one of the accessible alternatives, so that men can shoulder their part of contraceptive responsibility in a shared and mutual way. This approach makes it possible to finally address these issues relating to sexuality, fatherhood and fertility.

State of affairs

As of 2022, it is still not officially possible to use the thermal contraceptive method, even though it is effective and reversible.

  • 1979 - Creation of ARDECOM (association for research and development of male contraception)

    A group of libertarians founded ARDECOM, which for almost ten years united around 200 members in its men's discussion groups.

  • 1985 - Dr Roger Mieusset highlights the possibility of contraception by testicular ascent

    As part of the experiments carried out in conjunction with ARDECOM, Dr Roger Mieusset highlights the impact of testicular lifting on male fertility in a study.

  • 2018 - Maxime Labrit invents the Andro-Switch

    The authorities suspend the sale and distribution of the Andro-switch until it complies with European regulations.

  • December 2021 – Sales of the ring are suspended

associations and representatives on the ground

Family Planning, associations and collectives provide the public with various tools to learn about male contraception: sharing experiences, discussion groups, group consultations, workshops, networking.



Since the 1970s, ARDECOM has been campaigning against patriarchal decisions and has been supporting the development of male contraception.

Thomas Boulou

Based in Quimper, the Thomas Boulou collective provides a Testicular Contraception & Male Responsibility service every first Saturday of the month.


GARCON has been campaigning since 2019 for the research and development of contraceptive methods. Its primary objective is the diffusion and popularisation of the various contraceptive methods that exist today, particularly methods termed male.  


Tired of caregivers with sexist, lesbophobic, transphobic, racist, etc. practices, a group of feminist activists set up Gyn&Co, a directory of caregivers who have a feminist approach to gynaecology.

Family Planning

A feminist and popular education movement, Family Planning campaigns for the right to sexuality education, contraception, abortion, equal rights between women and men and fights all forms of violence and discrimination.


La Société d’Andrologie de Langue Française est une  (SALF) is an association of general interest that brings together doctors and researchers in men's health from 13 French-speaking countries. SALF has 40 years of experience in male contraception research.

medical questions

Thermal contraception is still not widely recognised, yet it has been the subject of a large number of clinical studies over the past 40 years. Here is what you need to know about it

15 clinical studies

Followed by over 122 volunteers between 1985 and 2019 for up to 48 months.


Of the 122 volunteers, only one pregnancy was reported due to misuse of the method.

Side effects

Before trying testicular lifting, we invite you to attentively read all the instructions for using the ring:

We are currently collecting data on possible skin irritations (which can be easily soothed with liniment) as well as rare cases of residual urination experienced after wearing the ring.
