Every 28 days, most women of reproductive age release an egg (ovum) from their ovaries for potential fertilization by a sperm and resulting pregnancy. This is ovulation. The cycle of events that prepares the egg for this event is the ovulatory cycle. But the egg also needs a supportive place to land and grow after fertilization. This place is the endometrial lining of the uterus. The menstrual cycle prepares the uterus for implantation of the egg and aligns precisely with the ovulatory cycle, also starting anew every 28 days.

How can all of this machinery line up?

In this AudioBrick, we’ll cover the phases of the ovulatory cycle and the menstrual cycle, along with the hormonal changes that occur with each cycle.

After listening to this AudioBrick, you should be able to:
  • Describe the phases of the ovulatory cycle and how ovulation occurs.
  • Describe the phases of the menstrual cycle and how the endometrium changes during the cycle.
  • Describe how gonadotropin-releasing hormone, follicle-stimulating hormone, luteinizing hormone, estrogen, and progesterone control the menstrual and ovulatory cycles.
  • Describe the timing of the various phases of the menstrual and ovulatory cycles, including the hormonal changes that occur during each phase.

You can also check out the original brick from our Reproductive collection, which is available for free.
