Control your fertility very simply


Male contraception other than the condom actually exists. Have you ever heard of thermal male contraception (TMC)? It is a physiological process inherent in male mammals, and therefore simply natural, which excludes the use of drugs. Hmm, maybe that's why Pharmaceutical industry does not promote it, explaining why you have never heard of it?

The brief discussion below shows how male fertility, which is permanent, impacts global demography. Consider the following two cases:

    • 1 fertile man living with 100 fertile women: this situation could in theory lead to up to 100 pregnancies per period of 9 months!
    • 1 fertile woman living with 100 fertile men: in this situation there can, at most,only be one pregnancy per period of 9 months.

Men may originate several pregnancies in parallel, and this is why they have a greater responsibility in demography: "With great power come great responsibilities".

Male contraception should weigh more than female contraception but, yet, it is the all the contrary that is advocated by the pharmaceutical industry in order to sell. In fact, thanks to TMC, men can take control of their fertility and choose the right moment and the right person to become parent with.

We strive to implement a simple and practical solution so that every man who wishes can easily access TMC. This solution is healthy and with no side effects. It differs widely from pharmaceutical products which frequently imply side effects. So, please discover our solution right below. It suits you! And please, spread the word around you. It is truly important. It will, for sure, help deeply some around you. Thank you!!

Einfach und effizient

Ich nutze das Set jetzt schon mehrere Monate und kann es nur (wärmstens) empfehlen! Die regelmäßigen Spermatogramme beweisen die Wirksamkeit der Methode, und das alles ohne irgendwelche Nebenwirkungen oder Eingriffe! Für Personen, die Spermien produzieren, gibt es m.E. keine Ausrede mehr nicht thermal zu verhüten.

Une belle innovation!

Equipe très réactive et disponible pour répondre à nos interrogations. Cela fait maintenant 2 mois que nous utilisons le boxer thermique et le spermogramme a été plus que concluant!! Ma fiancée a pu arrêter ses contraceptions (pilules, stérilet) qui lui rendaient la vie dur. 3 ou 4h de mon temps pour la soulager... ce n'est pas grand chose, surtout qu'il n'y a pas de réelles contraintes!! Nous en parlons un maximum autour de nous car même les médecins ne sont pas du tout au courant de cette technique... Nous recommandons vivement !!

Funktioniert perfekt

Nach 2 1/2 Monaten konnten bei mir keine Spermien mehr im Ejakulat nachgewiesen werden. Angenehme und einfache Benutzung, ohne jegliche Nebenwirkungen. Die Wärme ist gerade richtig und nicht zu heiß. Ich verwende die Unterhose meistens bis der Akku leer ist. Endlich eine reversible Möglichkeit, langfristig Verantwortung über die eigene Fruchtbarkeit übernehmen zu können.

It works!

I found Jemaya during a desperate web-surf for male contraception. I looked everywhere for a way that I could take control of my fertility that didn't involve condoms or surgery but the options for men is unfortunately very slim. When my gf refused to take any form of female birth control as well as refusing to have condom sex, I knew that action needed to be taken if I was to avoid the overwhelming pain of unplanned fatherhood. By wearing the underwear for 1 full battery charge a day, I achieved azoospermia (zero sperm count!) in around 6 weeks. At week 3, lab test confirmed I had a count of 50 million but was diagnosed with teratozoospermia or abnormal morphology and borderline concentration. at the end of week 6, a laboratory test confirmed I had reached the zero mark. I haven't noticed any side effects other than a very minor decrease in the size of my balls. However, I still have a healthy libido so I'd take slightly smaller balls over being an unplanned parent any day! Thank you Jemaya!
