Editor’s Note
Dear reader,
Many guides about periods are written with daughters in mind. Parents search for one about sons, and this is it. It is written for the adult at home, not for the child. It covers when to start, which words to use, and what boys tend to ask. It leaves your family’s values to you. The goal is small and practical: a calm conversation, and then another one.
— The Editor
A boy will share classrooms, teams, homes and workplaces with people who have periods. Some boys will have periods themselves. A children’s health site in the United States puts the case simply: “Girls and boys need reliable information about periods. So make sure you talk to your sons, too.” This guide is for parents and carers who want to do that without fuss.
Why sons, too
Attitudes to periods are learned. In one survey of 802 adults aged 18 to 44, men reported more negative attitudes toward menstruation than women. The researchers found the difference was “explained largely by heteronormative attitudes and sexism.”
A note on words: the sources we cite in this guide say “girls”, “women” and “men”. We keep researchers’ words so we report their findings accurately. The Reading Room is for everyone who menstruates.
Research on teaching boys about periods is limited. The studies found come mostly from India, Ghana, Tanzania, Uganda and Bangladesh, and the Editor found none from Canada. So this guide makes no promise about results. It treats the conversation as a matter of information and courtesy.
When to start: early and small
“By the time they’re 6 or 7 years old, most kids can understand the basics of periods,” according to the same US children’s health site. It suggests natural moments: a question about bodies or babies, or a trip to buy period pads or tampons.
A Canadian children’s hospital gives general advice that fits sons as well as daughters: “If your child has not brought up the topic as they near their preteen years, it is up to you to initiate the conversation.” It adds: “If your child’s friends and the Internet are their only sources of education, they may receive some poor advice.”
The US site quoted above advises against “one big talk at a particular age”. Instead, it says, “start the conversation early and slowly build on your child’s understanding”. A first answer can be two sentences. More can come later.
What school covers, and what it may not
In Ontario, periods are part of the Grade 5 curriculum for the whole class, not only girls. The 2019 Health and Physical Education curriculum expects students to “describe the processes of menstruation and spermatogenesis, and explain how these processes relate to reproduction and overall development” (expectation D1.4). Grade 4 covers the changes of puberty (D1.5). Families can ask for their child to be excused from these lessons, under their school board’s policy.
Glossary · Puberty
The years when a child’s body changes toward an adult’s. SIECCAN’s guidelines describe “the physical, biological, psychological, emotional, and social changes associated with puberty”.
Says who? SIECCAN, 2019.
Curricula differ by province and territory. The Editor has checked Ontario’s in full, and not yet the others. Ask your child’s school what is taught, and when.
Nationally, SIECCAN’s Canadian Guidelines for Sexual Health Education (2019) are guidance, not a curriculum. They say sexual health education should be accessible “to all people inclusive of age, race, sex, gender identity…” For ages 8 to 10, the benchmark is to “Understand the physical, biological, psychological, emotional, and social changes associated with puberty.”
The words to use
Use the correct words: period, blood, uterus, vagina. They are the words Ontario’s curriculum uses, and the words a doctor uses.
Keep the language wide enough for real life. “People who have periods” is accurate. So is “most girls, and some boys, have periods.” Not every girl has periods, and some boys do. You do not need to guess which your son is. Speaking this way leaves room for him, his friends and his future.
Five questions boys ask, and short answers
“What is a period?”
Blood and tissue from the lining of the uterus leave the body through the vagina. A whole period is about 2 to 3 tablespoons of blood, according to Canada’s SOGC.
“When do periods start?”
Most girls get their first period between ages 10 and 14, according to the SOGC.
“Will I get one?”
Most boys won’t. Some boys will, and some girls never do. Bodies differ. (Answer adapted to the child’s age; see “If your son will have periods himself”.)
“What are period pads and tampons for?”
They take in or collect the blood. There are several kinds: disposable period pads and liners, tampons, cups, discs, period underwear and reusable period pads. Different people choose different ones.
Glossary · Period products
The items people use to absorb or collect period blood: disposable period pads and liners, tampons, cups, discs, period underwear and reusable period pads. Definitions vary: for its workplace rule, Canada’s federal government defines “menstrual product” as “tampons and menstrual pads”.
Says who? ESDC.
“Why is it a big secret?”
It doesn’t have to be. Ontario’s curriculum includes this sample student response: “Not everyone experiences these changes at the same time and in the same way, so teasing people about these changes isn’t right. It can be very hurtful.”
Glossary · PMS (premenstrual syndrome)
The physical and emotional symptoms some women have in the weeks before a period, such as mood swings, tiredness, bloating and headaches.
Says who? NHS (UK), “PMS”, reviewed 2024-06-18.
A good brother, classmate, teammate and friend
Kindness here is simple and concrete.
- Don’t tease. The Ontario line above says why: “Not everyone experiences these changes at the same time and in the same way.”
- Know where things are. If a sister or a guest asks, he can tell her where the period pads are kept at home, without comment.
- Respect privacy. A period is someone else’s business unless they share it.
- Offer help, then step back. In forums, parents describe a young friend quietly asking another adult for help. Knowing that adults can help, and who to ask, is useful for anyone.
For older sons, one fact shows how ordinary periods are at work. Since 15 December 2023, federally regulated employers in Canada must provide tampons and period pads in all toilet rooms in the workplaces they control, “regardless of their marked genders”.
Glossary · Period poverty
Not being able to get what you need to manage a period. A 2024 Canadian review uses this definition: “the lack of access to menstrual products, sexual and reproductive health education, safe waste management, and adequate facilities”.
Says who? Lee, Toory, Harrison, Canadian Journal of Public Health, 2024.
If your son will have periods himself
Some sons are trans boys, and some of them will have periods. If that is your son, the same approach applies: correct words, calm answers, and his privacy respected. Let him lead on the words he uses for his own body. More in the Reading Room: “Period care and gender dysphoria.” Kids Help Phone and the Access Line below are open to him.
What to say, in a sentence or two
- “A period is when blood and tissue from the lining of the uterus leave the body through the vagina.”
- “Most girls, and some boys, have periods. Not every girl does.”
- “It usually starts somewhere between 10 and 14.”
- “It’s not something to tease anyone about.”
- “If a friend or your sister needs a period pad, you can tell her where they are, or find an adult.”
- “You can ask me anything about it. If I don’t know, we’ll look it up together.”

What this is not
This guide covered bodies, words and kindness. It did not cover religion, sex or family values; those belong to you. It did not summarise every province’s curriculum; it quoted Ontario’s and SIECCAN’s guidance. It is written for adults, not for children. It does not recommend any product.
Next in the Reading Room: “A kind guide to first periods.”
Drafted and checked against its sources with our proud team of AI assistants; read and signed by the Editor.
This guide is general information, compiled by the Editor from the sources listed below. It is not medical advice, and the Editor is not a healthcare provider. For anything about your child’s health, talk to a healthcare provider.
No rush. We like reading slowly, one short piece at a time. The articles will wait for you.
