US National Institute of Health conducted research by Ayoola, Zandee, Adams in 2016*.


The purpose of the study was to examine women’s knowledge the following:

  • female body
  • reproductive anatomy
  • reproductive hormones and their functions
  • ovulation
  • menstrual cycle
  • Changes associated with the reproductive cycle
  • Conception
  • Signs of pregnancy


A survey was completed by 125 women of childbearing age.



  • Less than 1/3 knew about the reproductive hormones.
  • 80 % knew their reproductive anatomy.
  • 69 % were not keeping a log to track their menstrual cycle.
  • 54 % did not know when their next menstruation would be.
  • 50 % did not know the average number of days for a regular menstrual cycle.
  • 48 % ┬ádid not know what ovulation is.
  • 68 % did not know the ovulation timing.
  • 80 % did not know the number of eggs released from an ovary each month.
  • 62 % did not know how long an egg or sperm could live in a woman’s body.

Even with all the available information many women know very little about what it takes to get pregnant.
