How to Choose a Sperm Donor: The Questions That Actually Matter
For many women considering solo motherhood, choosing a sperm donor can feel like one of the biggest decisions of the entire journey.
And in many ways, it is.
But if you’ve started researching donors, you’ve probably discovered something quickly — there’s a lot of information, and not all of it actually helps you make the decision.
Donor profiles can include everything from eye colour and height to personality traits, hobbies, and long medical histories.
It can feel like you’re expected to choose the genetic blueprint for your future child.
But the truth is, when it comes to donor conception, there are far more important questions than whether someone plays the piano or likes hiking.
If you're trying to decide how to choose a sperm donor, these are the questions that actually matter.
First: Get Clear on Your Donor Options
Before choosing a donor, it’s important to understand the different types available.
Depending on where you live and your circumstances, you may encounter three main options:
Known Donor
A donor who is someone you already know — often a friend or acquaintance.
This option can offer a known genetic connection but requires careful conversations about expectations, boundaries, and legal agreements.
Recruited (Known) Donor
Someone you meet specifically for the purpose of donation, often through donor groups, Facebook groups, apps, or online communities.
This option can provide more control over the process but also requires careful screening and legal protection.
Clinic Donor (Unknown, ID Release Donor)
A donor selected through a fertility clinic or sperm bank.
These donors have typically undergone medical screening and counselling, and legal frameworks are often clearer.
Each option has advantages and challenges, which is why understanding your priorities before choosing is so important.
The Questions That Actually Matter When Choosing a Donor
Instead of focusing on superficial traits, these are the questions that most experienced solo mums recommend thinking about.
1. What Level of Future Contact Feels Right for You?
One of the most important decisions is the level of connection your child may have with their donor in the future.
Some donors are:
identity-release (child can learn their identity later)
open to contact
anonymous (in some countries)
known - so you can have a relationship with them from day one, in this scenario, clear boundaries and expectations prior to conception are important to ensure you are both on the same page
Many solo mums today prefer identity-release donors so their child has the option to learn more about their genetic origins later in life. Some prefer the ability for their child to have a relationship with the donor from day one and for the donor to have some involvement in their life. If considering a known/recruited known donor, it is important that both parties do their due diligence, including donor counselling and legal agreements, to try to avoid complications in the relationship in future.
But this is a deeply personal decision.
2. What Are Your Values Around Donor Siblings?
When using donor sperm, there may be other families who have children using the same donor.
Some families choose to connect with donor siblings.
Others prefer not to.
Thinking about how you feel about these possibilities can help guide your donor choice.
3. Does the Donor's Medical History Matter?
Medical history is one of the most important practical considerations.
Donor profiles through a clinic or sperm bank usually include:
family health history
genetic screening results
known hereditary conditions
This information helps fertility clinics reduce the risk of passing on genetic conditions. These tests are available and encouraged for those using known or recruited known donors.
4. What Traits Actually Matter to You?
It’s easy to get caught up comparing donors based on height, education, hobbies, or personality descriptions.
But many experienced solo mums say that focusing too heavily on these details can make the process unnecessarily stressful.
Instead, many women choose donors based on:
health history
values around identity-release
general physical similarities, including ethnicity
the answers to the questions, such as their reason for donating
Remember that children are shaped by far more than genetics.
It’s worth noting that if you are considering using a donor of a different ethnicity from yourself, you should thoroughly research this option. With current sperm shortages, it can be an appealing option, but not having lived experience of growing up as this ethnicity, are you best prepared to support your child if they encounter racism or unconscious bias as a result of your decision?
5. What Feels Right for Your Future Child?
One of the most helpful ways to approach this decision is to imagine explaining it to your future child one day.
Questions you might ask yourself include:
Would I feel comfortable sharing this donor's story?
Does this decision align with my values?
Would my child feel supported in understanding their origins?
Thinking about the long-term perspective can help simplify the decision.

One More Important Thing: There Is No Perfect Donor
Many women feel pressure to choose the “perfect” donor.
But perfection doesn’t exist.
What matters is making a thoughtful, informed decision that aligns with your values and feels right for the family you’re creating.
Many solo mums say that once their child arrives, the donor becomes just one small part of their story.
The real magic is the relationship you build with your child.
