Putting the ring on and taking it off is very easy, it just takes some getting used to. To get the Andro-switch moves right, you can find all explanatory videos under the TUTORIALS tab.

How should you place the contraceptive ring?

In order to be efficient and comfortable to wear, the contraceptive ring needs to be placed on the penis, as close to the pubis as possible. It is important to slide the whole penis plus all of the scrotum skin – without the testes – into the thermal ring. Lacking space, the testes will naturally move upwards and into the pubic sac.

The thermal ring needs to be touching the pubis (the area right above the penis) and the perineum (the area between the anus and the scrotum).

The thermal ring allows the testes to remain in an upward position.

Andro-switch is designed to create a slight push-up effect that retains the testes in this upward position.

If you accidentally inserted a testicle into the thermal ring, remove the ring carefully and start again.

Here is an image depicting the position of the thermal ring. You will find that the testes are above the device, which is in contact with the pubis and the perineum. The scrotal sac is obviously empty. The device is placed correctly if the testes are resting in an upward position as shown on the picture.

Putting the thermal ring on:

  1. Wash your hands. Wash the thermal ring with a gentle soap and lukewarm water, rinse and pat dry with a clean towel or soft cloth.
  2. Insert the penis into the thermal ring, then gently slide the scrotum skin into the ring until the ring is in contact with the pubis (the area just above the penis) and the perineum (the area between the anus and the scrotum). Lacking space, the testes will naturally move upwards and into the inguinal sac, at the root of the penis, where the heating process will start.
  3. Wash your hands.

You must then check that the testes are in the inguinal sac with a light palpation. If they are resting above the thermal ring, that’s the correct position.

Taking the thermal ring off:

  1. Wash your hands.
  2. Gently slide the ring down to remove it.
  3. Wash your hands. Carefully slide the thermal ring to remove it. Clean the thermal ring with mild soap and lukewarm water, then rinse before gently patting it with a clean towel or soft cloth. Wash your hands.
  4. Wash your hands.

Thanks to the document "Instructions for use: ANDRO-SWITCH installation and removaldocument included in the Andro-switch Pack, you will be guided step by step to efficiently place and remove the thermal ring..

First trial & fittings 

You can just lightly shear you hair with scissors as in a brush cut, but no shaving – this helps with the gripping effect. 


  1. 1. The resting position, in which you only slide the penis and scrotum (the part just below the penis) through the ring. This is perfect at night or when you're not moving around too much.
  2. 2. The second position, when you are active, in which you also need to place the groin skin inside the ring. In this position, you need to secure this portion of skin with the inguinal canals inside the ring on both sides. I explain this very clearly in the protocole de pose et retrait. 

Too large or too small?

A ring is considered too large when despite those moves, it doesn't stay in place and a testicle slides back down below the ring. As long as they are above or at the same level as the ring, the testicles are exposed to the heat of the body. A ring is considered too small when it marks your skin just like a tight sock would mark your calf skin, and also when erections don't subside by themselves. This means your penis remains filled with blood due to excess compression. In this case, take the ring off. 


Whether too large or too small, email me the following information at [email protected] the following information :

  • Ring too large or too small?
  • Erect width:
  • Resting width:
  • Order number:
  • Confirmed delivery address:

I'll get everything you need for your fittings ready. Upon reception, you have 7 days to do them and call me if needed. When you know for sure which model fits you best, email me to let me know and organize the return. 


  • Some guys like to keep two different sizes, one tighter and one looser to be used for various daily activities.
  • As an alternative, you can try a hybrid between different thermal-method tools. Contact me to discuss this option if needed.
  • Another alternative would be to try a hybrid between different natural methods (symptothermal method, diaphragm, thermal method...). Contact me to discuss this option if needed.
  • When going for this practice, you have two main goals: one is about mastering the technical aspects of testicle lifting, and the other is about the need to have a contraception method. You can achieve both at the same time, but you can also dissociate them. Contact me to discuss this if needed.

Lying down, calm mind, let your fingers touch, feel, smell: pubis, groin, penis, scrotum, testicles, perineum.

With two fingers, slightly remove the area of the pubis, the pocket where the testicles will migrate.

Slide your fingers on each side of your penis, along the groin and inguinal canals where the testicles will slide.

To apprehend the scrotum, its volume, up to the perineum, where the ring will be placed.

Gently roll each testicle back and forth between your thumb and index and middle fingers.

Explore the spermatic cord that connects the testicle to the rest of your body.

Some suggestions: use the palm of your hand, a mirror, feel the mobility and plural elasticity of the different parts, visualize the path of testicular rise, take your time.
