Niger: launch of Caya® Diaphragm and Caya® Gel

KESSEL MEDintim, WCG Cares (WCG) and Population Services International (PSI) announced the launch of the Caya® Diaphragm and Caya® Gel in Niger.

The introduction of the Caya® Diaphragm and Caya® Gel in Niger is supported by the Expanding Effective Contraceptive Options (EECO) project, which is funded by the United States Agency for International Development (USAID).

The EECO project, led by WCG and implemented in partnership with PSI, was designed to support the introduction of new and improved contraceptive methods that address method-related reasons for non-use of family planning to better meet the reproductive health needs of women and girls worldwide.

The launch of the Caya® Diaphragm and Caya® Gel, a non-hormonal, discreet and reusable barrier method, supports WCG’s and PSI’s joint efforts to expand access to an array of contraceptive options. PSI will market and distribute the Caya® Diaphragm and Caya® Gel in Niger’s capital of Niamey, training community health workers and healthcare providers to offer the method to women alongside other options within the context of informed choice.


Niger has one of the world’s highest fertility rates, with women having more than seven children in their lifetime on average, in part due to extremely low use of contraception. Yet the Government of Niger is committed to increasing contraceptive use not only as a means to reduce maternal and child morbidity and mortality but also to boost economic development.

KESSEL MEDintim, WCG and PSI are dedicated to increasing access to a full range of contraceptive options in Niger, including those that respond to preferences for non-hormonal, on-demand methods like the Caya® Diaphragm and Caya® Gel. Unlike previous iterations of the diaphragm, the Caya® Diaphragm is “one size fits most,” eliminating the need for a provider fitting in countries like Niger with shortages of trained healthcare providers. 

“Our market research shows that women and men desire more contraceptive options that are within their control and have no side effects,” said Moumouni Boubacar, EECO Project Manager at PSI Niger. “The Caya® Diaphragm puts power in the hands of the couple, which can decide when they want to start and stop contraception with no need to see a provider in a busy health care center.”


“We are excited to see the response of women and providers to the Caya diaphragm—especially​ to see if Caya can help meet the needs of women who do not want to use other types of contraceptives,” said Martin Kessel, CEO of KESSEL MEDintim. “We know women in other countries have easily learned to use Caya and like this new method, so in Niger this will be explored. Since diaphragms have not been available or promoted in decades, we are not just testing acceptability of another variation of a contraceptive, we are introducing a new type of method to women and their partners, and even to family planning providers, who have not had an option like this before.”

“Women’s contraceptive needs change throughout their lives and they need methods that align with their unique circumstances,” said Shannon Bledsoe, WCG Executive Director. “The introduction of this on-demand, non-hormonal method gives women in Niger one more contraceptive choice.”

Singa®: Production and distribution of the new diaphragm


KESSEL MEDintim GmbH is preparing the production and distribution of the new Singa® diaphragm. It is to be delivered in late summer 2019.

Important note: As soon as the Singa® diaphragm is available, it will be announced at Please refrain from previous telephone enquiries. It is possible to be placed on an information waiting list by e-mail: Prospective customers may write a short e-mail to

What’s new about the Singa® Diaphragm?

The Singa® diaphragm is named after the inventor of the diaphragm Johann Wilhelm Mensinga (1836 – 1910), a pioneer of modern contraception.

The Singa® diaphragm will be round in its traditional form and provided with a membrane. The available sizes also correspond to the classic diaphragm: 60mm, 65mm, 70mm, 75mm, 80mm, 85mm and 90mm outer diameter.

New features of the Singa® diaphragm will be the material and the spring washer: In conventional diaphragms, the spring was made of metal (spiral spring and/or flat band spring), coated with latex or silicone.

The Singa® diaphragm, like the Caya® diaphragm, will have a polymer (Nylon®) spring washer that has better properties than metal springs and is also lighter. The Singa® diaphragm is also color-coded to match the Caya® diaphragm, as shown in the file below.

The Singa® diaphragm is based on the technology and manufacturing experience of the Caya® contoured diaphragm. This anatomically and ergonomically shaped diaphragm was launched by KESSEL MEDintim GmbH in April 2013. Over 150,000 women have opted for it to date.

Why a round, traditional diaphragm continues to be necessary

The Caya® diaphragm is suitable for a good 87% of all women. However, the remaining 13% require a different diaphragm for anatomical reasons in order to be able to use contraception safely.

The Singa® diaphragm will therefore be of interest to the following women:

– Women who need a smaller diaphragm than the Caya® Diaphragm (60mm diameter)

– Women who need a larger diaphragm than the Caya® diaphragm (85mm and 90mm diameter). These are women who may already have had several vaginal deliveries.

– Women who need a firmer spring tension than the Caya® diaphragm offers. The Singa® diaphragm has a slightly firmer spring tension and therefore sits more firmly in the upper vaginal vault than the Caya diaphragm.

As with all traditional diaphragms, the size of the Singa® diaphragm must be adjusted by a professional (gynaecologist, midwife, family planning clinic) before first use.

The Caya® diaphragm will continue to be the most widely used diaphragm in the world. Further information can be found at With its seven sizes, the Singa® diaphragm gives all women the opportunity to use a diaphragm as the contraceptive method of their choice.

As always, we were interested in the following: Who are the users? What does their lifestyle look like? How satisifed are they with the Caya?

We are pleased with the positive results that can be downloaded below. After 5 years and approx. 150,000 Cayas on the market, we were able to start a revival of the diaphragm as contraceptive method.

Important information: Availability of Milex Wide Seal

Milex Wide Seal Diaphragm, Size 60 - 90 mm

The diaphragms of the manufacturer MILEX (USA) of the brand Wide Seal, sizes 60 to 90 mm, are no longer available in Europe.

In the US these diaphragms are not available online, but only directly from the gynecologist. In addition, they are available only on prescription.

Women who previously used a classic diaphragm of sizes 65mm, 70mm, 75mm or 80mm can alternatively use the CAYA® contoured diaphragm. The Caya® Diaphragm is available without a prescription in pharmacies and online.

Women who want a diaphragm of size 60mm, 85mm or 90mm can temporarily not find these sizes on the market.

We are currently preparing a traditional diaphragm in sizes 60 – 90mm and will launch it in the first half of 2019. More information will then be published.

Post marketing survey for Vacuum Erection Devices (VED)

Latest Results: Jan 2017 – Aug 2018
Active Erection System® and Manual Erection System®

Since January 2017 until today, the users of the vacuum erection devices Active Erection System® and Manual Erection System® were directly questioned.

We were interested in the degree of satisfaction with the product and in the frequency of use, but also in the age- and health-related prior history of the respondents. The survey was undertaken by company KESSEL MEDintim GmbH. As gratification each respondent received a tube of Animé lubricant as well as two constriction rings.

Overall, the survey reached 2500 men so far, and due to the very personal nature of the topic, it was partly also anonymous. This third assessment is based on the answers of the first 300 respondents.

5 years of Caya® Diaphragm

Five years of Caya® Diaphragm – the successful story of a proven contraceptive method


The comeback could not have been better:
On 9 April 2013 the first Caya® Diaphragm was delivered to the Engel Apotheke in Fulda, Germany. After 5 years, more than 110,000 women worldwide made their choice for the Caya® Diaphragm – as their reliable method of contraception.

Up to now, over 110,000 Caya®s reached women in more than 32 countries: Europe, the US, Australia and most recently the land of the Kiwis, New Zealand. For an overview of all Caya® countries, find our global map on

Where does this success come from? The annual Caya® post marketing surveys show a clear result:
More and more women want a hormone-free and safe contraception without side effects – which they only use when they need to. 42% of the participants said they had taken the pill before they started to use the Caya® Diaphragm. Over 14% had used another hormonal method before.*

The trend is away from hormonal contraception towards a self-determined method which is, in case of the wish for a baby, reversible.

Is there a certain type of Caya® woman? Actually, no. It’s sexually active women in their fertile days from 18 to 45 years, so the Caya® is being used in different phases of life. What is exciting, is that a third of the respondents said that they had „better and more relaxed sex“ than before with the Caya® Diaphragm.

What are the next steps for this year? Caya goes Africa: in June 2018, the Caya® Diaphragm will be introduced in Niger. Nigeria and Madagascar are already in preparation.
