Our Philosophy
Support Instead of Prescriptions
There is no set plan for starting a family. Different life situations, desires, and circumstances lead to different paths. At GENTIVES, our commitment is not to pressure you into a decision, but to support you with professional clarity, human warmth, and experience. Together, we develop a roadmap—and find the path that’s right for you.

Our commitment: Support tailored to your needs
The path to starting a family is unique—and not always straightforward.
Starting a family can take many forms. Which options are right for you depends on your personal situation.
Some decisions come quickly, while others require time, guidance, and discussion.

One option: Sperm donation
Responsibly selected, personally suitable
For many people, sperm donation is a viable path to starting a family. At GENTIVES, we place particular emphasis on responsible and careful selection.
In addition to medical and genetic criteria, we also consider personal characteristics, values, and life backgrounds. Our goal is to introduce you to a donor who fits your life situation and your future family history.
Additional paths to family happiness thanks to our international partners
In addition to sperm donation, we also advise you on other options for starting a family. We collaborate with select international partners who offer the highest medical standards and years of experience.
Our international networks enable structured processes, legal certainty, and access to established facilities.

Founder & personal story
“My own family history has shown me how crucial trust, transparency, and responsible support are when starting a family.“
GENTIVES’ work is shaped by our own experience. As founders, we have personally gone through the journey of medically assisted family formation.
This perspective forms the foundation of our work: to provide prospective parents with a dignified, transparent, and professionally guided path to starting their own family.
Together with long-standing international partners, we combine expertise, structure, and personal responsibility.
Your Questions – Our Answers
Each case is viewed individually and handled discreetly, covering all possibilities for family formation. The cost of the initial consultation (Zoom) will, of course, be credited should a match result.
We exclusively match open donors of both genders, both domestically and internationally. The exact possibilities available will be outlined during the initial consultation.
Our donors are hand-selected not only for health reasons but also for their attitude. Responsibility and the well-being of the future child are our top priorities, which is why placement is limited to a maximum of 6 families.
Of course, you can take a close look at our donors in our database before placement. In most cases, personal contact is also possible or even encouraged.
You’re not just anyone. You might be exactly the person a family somewhere in the world has been hoping for. Get informed now with no obligation—and take the first step.
The first step toward starting your own family
We understand how significant and personal this decision is.
We are happy to take the time to understand your situation and provide you with personalized support.
Your inquiry is, of course, non-binding and will be treated with the utmost discretion.
