CanPKU+ | Growing Up & Looking Ahead
Your Body. Your Choices. Your Future.
The Birds, the Bees & Rare Metabolic Needs
Growing up comes with questions about your body,
relationships, independence and the future.
Living with PKU, HCU, MSUD or a urea cycle disorder
can add a few questions of its own.
You deserve information that helps you understand
your options without pressure or judgment.
♥
Your questions matter.
No question is too small, too early or too awkward.
Start Where You Are
You do not need to have your future figured out.
Maybe you are just starting to think about relationships.
Maybe you are wondering whether you could have children
someday. Maybe you already know that parenthood is not
part of your plans. All of those feelings and choices
deserve respect.
Understanding how your metabolic condition may affect reproductive health can help you make informed decisions whenever the time is right for you.

Let's Talk About It
The birds, the bees and a few extra questions.
Dating, relationships, contraception and reproductive
health are important topics for everyone.
If you have an inherited metabolic disorder,
there may be additional considerations involving
your health, medications or nutrition.
You can ask your healthcare team about these topics before you are thinking about pregnancy. You can also ask for a private conversation.

Good questions to ask
• Does my condition affect contraception?
• Could pregnancy affect my health?
• When should I begin planning?
• Can I speak with someone privately?
• What happens if I become pregnant without planning ahead?

Four Communities. Different Needs.
What does my condition mean for pregnancy?
Successful pregnancies have been reported among people
living with PKU, HCU, MSUD and some urea cycle disorders.
However, risks and care needs vary by condition,
subtype and individual circumstances.
Pregnancy planning should involve your metabolic healthcare team and appropriate pregnancy specialists. Explore the Understanding Your Rare pages to learn more about each condition.

PKU
Blood phenylalanine levels are especially
important before and during pregnancy.
Early planning and specialized care help
protect a developing baby.
Understanding PKU →
HCU
Pregnancy care may require special attention
to metabolic management and blood-clotting
risks, depending on the type of HCU.
Understanding HCU →
MSUD
Metabolic stability and carefully planned
nutrition and medical care are especially
important during pregnancy, delivery
and recovery.
Understanding MSUD →
UCDs
Pregnancy and the postpartum period may
increase the risk of high ammonia levels.
An individualized metabolic and obstetric
care plan is important.
Understanding UCDs →
These are introductory summaries only.
Different subtypes may require different care.
Condition-specific reproductive-health resources
will be added to the Understanding Your Rare pages
following clinical and editorial review.
Conversations Worth Having
You can start with just one question.
• What should I know about reproductive health and my condition?
• Does my current treatment affect my options?
• What should I know about contraception?
• What if I am not following my usual metabolic care plan?
• What should I do if I think I might be pregnant?
• What happens if I become pregnant without planning ahead?
• Can I speak with someone who has lived through similar experiences?
• Does my current treatment affect my options?
• What should I know about contraception?
• What if I am not following my usual metabolic care plan?
• What should I do if I think I might be pregnant?
• What happens if I become pregnant without planning ahead?
• Can I speak with someone who has lived through similar experiences?
If you think you may already be pregnant, contact
your metabolic healthcare team promptly rather than
waiting for a routine appointment. Even if pregnancy
was not planned, asking for help early is important.
Community & Connection
Sometimes it helps to talk with someone who understands.
CanPKU+ is exploring ways to help individuals and
families connect with others who have relevant
lived experience.
This may include support for newly diagnosed families, young people navigating independence, and adults considering pregnancy or parenthood.
Peer connections can complement, but do not replace, professional medical care.

Mentorship & Peer Support
A coordinated mentorship pathway is being explored.
The goal is to help individuals and families connect
with people who have relevant lived experience,
without expecting one volunteer to provide every
type of support.
Program details, volunteer roles and contact arrangements will be shared once confirmed.

Your Future Is Yours
You deserve information, choices and support.
Whether you are curious about growing up,
navigating relationships, considering parenthood
or simply looking for someone who understands,
you do not have to figure everything out at once.
Knowledge is the key to helping you make choices that are right for you.
