Reproductive organs
Reproduction is the property of living organisms of leaving offspring like themselves and so continuing the species. In humans reproduction begins with the joining of two sex cells – a male sperm cell and a female egg cell (fertilisation); the single cell formed is called a zygote and combines the hereditary traits of father and mother. Male reproductive organs include a pair of testes (located in a skin sac, the scrotum, where sperm cells form), sperm ducts and accessory glands. The female internal reproductive organs lie in the pelvic cavity: a pair of ovaries (where egg cells mature, containing follicles), uterine tubes (oviducts), the uterus (a muscular sac where the embryo develops) and the vagina. Sex glands also produce hormones, which control bodily changes in adolescence. Reproductive organs are private parts of the body: speak openly with trusted adults (parents, a doctor) about their hygiene, respect for the body and personal boundaries; nobody has the right to touch your body without permission – in such a case tell a trusted adult at once.
Table: write organ names and functions under “Male” and “Female” (no drawings). If you have more questions, ask a trusted adult or doctor.
