Human Reproductive System and Sexual Maturation
Lesson 5 of 5
25 min
After Uwase's first period, three people give her advice. Her grandmother says quietly that in her day such things were never discussed with parents; an aunt or a grandmother explained them. Her religion teacher says that her faith sees the body as a gift from God, to be respected. Her biology teacher explains the hormones of the menstrual cycle and reminds the class that, under Rwanda's Constitution, girls and boys have equal rights.
Uwase listens to all three. Must she choose one voice and ignore the others? This lesson looks at how culture, tradition, religion and the law shape views of sex, gender and reproduction in Rwanda, and how to understand and respect them side by side.
Definition
Sex: the biological differences between males and females, such as chromosomes (XX or XY), reproductive organs and hormones.
Gender: the roles, behaviours and expectations that a society considers suitable for men and women, boys and girls. Gender roles are learned, and they differ between cultures and change over time.
Gender equality: women and men, girls and boys, having the same rights, opportunities and value. Gender stereotype: a fixed, over-simple idea about what men or women are like or should do, for example "boys don't cry".
Definition
Culture: the shared beliefs, values, customs and way of life of a group of people. Tradition: a belief or custom passed down from generation to generation.
Taboo: a subject or action that a society avoids or forbids talking about or doing.
Worked example 1: sex or gender?
Decide whether each statement is about sex (biology) or gender (roles set by society), and explain.
| Statement | Sex or gender? | Reason |
|---|---|---|
| Only females can become pregnant. | sex | it depends on having ovaries and a uterus |
| Cooking is women's work. | gender | anyone can learn to cook; who cooks is decided by custom |
| Males usually have XY chromosomes. | sex | it is a biological fact |
| Girls should not study science. | gender (a stereotype) | ability in science does not depend on sex; this idea is learned, and it is wrong |
| Boys' voices deepen at puberty. | sex | testosterone makes the larynx grow |
Test: ask "Is this true of human bodies everywhere, or does it change from one society or time to another?" Biology is the same everywhere; roles change.
Figure 1: Three sources of guidance on sex, gender and reproduction. They do not always agree, but they share important values.
Rwandan culture places great value on the family (umuryango), on children, and on respect for elders. Researchers from the University of Rwanda and the University of the Witwatersrand who interviewed people working in health and education in Rwanda (published 2022) found that:
The same research found that when families do not talk about these topics, young people often turn to friends and the media, whose information may be wrong. Sexuality education in school is meant to add accurate information to the values young people learn at home, not to replace them.
Rwanda's Constitution makes the state secular (it has no official religion) and guarantees freedom of thought, conscience and religion. Many Rwandans follow a faith. The table shows the teaching of the two largest traditions on some of the questions in this unit. Within each faith, churches and scholars differ on some details, and many people follow other beliefs or none; ask your family or faith leader about the teaching of your own tradition.
| Topic | Christian teaching | Islamic teaching |
|---|---|---|
| Men and women | Both are made in God's image, with equal dignity: "God created man in his own image. In God's image he created him; male and female he created them." (Genesis 1:27) | Both come from one origin, with equal dignity: "O mankind! Be careful of your duty to your Lord Who created you from a single soul and from it created its mate and from them twain hath spread abroad a multitude of men and women." (Qur'an 4:1) |
| The body | The body is to be respected: "your body is a temple of the Holy Spirit who is in you" (1 Corinthians 6:19). | Modesty and self-control are asked of both men and women (Qur'an 24:30 to 31). |
| Sex and marriage | Sexual relationships belong within marriage: "Let marriage be held in honour amongst all" (Hebrews 13:4). Churches teach abstinence before marriage and faithfulness in it. | Sexual relationships are permitted only within marriage (Qur'an 17:32 forbids approaching unlawful sexual relations). Spouses are described as a source of rest and peace for each other, with love and mercy between them (Qur'an 30:21). |
| Family size | Children are a blessing. The Catholic Church teaches natural methods of spacing births; many Protestant churches accept other family-planning methods for married couples. | Children are a blessing. Many Muslim scholars accept family planning by married couples when both agree; views differ on the methods. |
Worked example 2: culture, faith and law in one decision
A family is offered money and gifts if their 15-year-old daughter, Ingabire, leaves school to marry an older man. Analyse the situation from each of the three sources of guidance in Figure 1.
Conclusion: all three sources, read carefully, point the same way: Ingabire should stay in school, and the offer should be reported to a trusted adult, the local leaders or the free child-abuse line 116.
Important
Respect differences, reject harm. You may meet classmates whose families and faiths hold views different from yours. Listen, ask questions politely, and never mock anyone for their beliefs, or for having none. But no culture, tradition or belief makes violence, forced marriage, or any sexual contact with a child acceptable. These are crimes, and they are never the child's fault.
Agree on rules first: one person speaks at a time; talk about ideas, not about people; nobody has to share anything personal.
Warning
Common mistakes. (1) Confusing sex and gender: biology is the same everywhere; roles change between societies. (2) Treating one person's practice as the whole teaching of a faith: each tradition has a range of views. (3) Thinking that respecting culture means accepting everything done in its name: the law protects everyone's rights, especially children's.
Tip
Memory hook: "Same body, different roles." If it is about the body, it is sex; if it is about the roles a society gives, it is gender.
Practice: culture, religion and the law
