You don’t need to wait for a partner to begin building your family. Whether you’ve always known you wanted to be a father on your own, or you’ve arrived at this decision more recently, Tammuz Family will help you understand your options and support you throughout the journey.
Men consider surrogacy for many different reasons. Some have always wanted to be a parent and see no reason to wait for a partner to make that happen. Others reach a point, often tied to age, financial readiness, or simply timing, where they decide this is the right moment to build their family independently. Whatever has brought you here, you deserve clear information, thoughtful guidance, and a path designed around your circumstances. Building a family without a partner does not mean navigating every decision alone. From understanding program eligibility and donor options to coordinating the medical, legal, and practical stages, our team will be by your side throughout the journey. Since 2008, Tammuz Family has supported the birth of more than 2,200 babies through surrogacy. We bring that experience to every journey while recognizing that every man’s story, priorities, and support system are different.

Building your family through surrogacy involves many important stages, from medical treatment and legal procedures to matching, pregnancy, birth, and returning home with your baby.
We begin by understanding your circumstances and what's brought you to this decision. Together, we identify the destination and plan that fits, and the documentation you'll need, including proof of single status where a program requires it.
01
You select an egg donor, and use your own sperm or a donor's where needed. Once your embryos are created through IVF, you begin the surrogate-matching process.
02
Your surrogate is medically prepared for embryo transfer. After the transfer, pregnancy testing and early scans are completed. Once pregnancy is confirmed, you receive updates while your surrogate continues with prenatal monitoring.
03
Throughout the pregnancy, you receive medical reports and updates while your surrogate follows the defined prenatal-care protocol. As the birth approaches, we help you prepare for travel, hospital arrangements, accommodation, and the practical steps that follow delivery. This includes preparing for the practical realities of arriving alone or with a support person, caring for your newborn, organizing accommodation, and completing the post-birth process before returning home.
04
After your baby is born, the local team coordinates the documentation required to register your baby and obtain the birth certificate. We continue supporting the practical process while you complete the citizenship, passport, exit, and travel requirements that apply to your family.

Every journey is different. Timing depends on medical processes, legal requirements, donor and surrogate availability, clinic schedules, documentation, third parties, and individual circumstances.
We have gathered for you all the answers to the most important and frequently asked questions, so you can find clear, reliable, and up-to-date information—all in one place, in a simple and convenient way.
Yes. Many men build a personal support system alongside the process, a close friend, family member, or community of other single fathers by choice, while our team guides you through the medical, legal, and logistical stages directly.
The legal process differs by destination and by your country of citizenship or residence. Before you begin, the applicable pathway should be reviewed by independent legal professionals so you understand how parentage, birth registration, citizenship, passports, and returning home may work in your specific circumstances.
In most cases, yes, subject to medical evaluation. If using your own sperm isn’t medically recommended, donor sperm is available, and we’ll walk you through what applies to your specific situation.

Through Tammuz, I became a father.
The team demonstrated professionalism and humanity beyond expectations, starting from the very first phone call—two years before the birth itself took place.
In my view, what makes Tammuz unique is their understanding that they are dealing with new lives—those of the newborns and the families whose lives are changing before their eyes.
