Key Stage 3
Meaning
Ovulation is one of the stages of conception and is when an ovum is released from an ovary.
About Ovulation
- The ovum travels along the edge of the oviduct, aided by cilia, following ovulation.
- Ovulation takes place on the 14th day of the menstrual cycle.
Key Stage 4
Meaning
Ovulation is when an ovum is released by a follicle in the ovary.
About Ovulation
- Prior to ovulation follicle stimulating hormone causes the follicles to grow and the ovum to mature.
- Ovulation is triggered by a sudden increase in luteinising hormone around the 14th day of the menstrual cycle which causes the ovum to be released from a follicle.
- Following ovulation the ovum travels along the edge of the oviduct swept along by cilia.
