💡 The human story
From a single fused cell to a whole new person — human reproduction weaves together special organs, gametes, a monthly cycle and nine months of care.
What happens in human reproduction?
- Reproductive organs mature at puberty and begin producing gametes — sperm in males and eggs in females.
- When a sperm meets an egg inside the female body, they form a zygote .
- The zygote develops into an embryo and eventually into a foetus in the uterus.
