Menstrual cycle: ovary, uterus and hormones

Move through a 28-day cycle and watch follicle growth, ovulation, the corpus luteum and the uterine lining.

Open the simulation

What to notice

Progesterone from the corpus luteum maintains the endometrium; if fertilisation does not occur it degenerates and menstruation follows.

Key relation

LH surge (≈ day 14) → ovulation

Try this

Move to day 14. Which hormone peaks?

What you can change

• Day of cycle: 1 to 28 day

More in How do Organisms Reproduce?

• Bacterial shapes and binary fission
• Double fertilisation
• Mitosis, stage by stage
• Kinds and agents of pollination
