As placental mammals, humankind gives birth to live offspring. Gestation begins on the first day of the preceding menstrual period, approximately two weeks before fertilization.

A human gestation period is comprised of three trimesters and generally spans about nine months. But how much do you know about fetal development? For instance, are you aware that certain cell types emerge solely during gestation, or that hair typically becomes more abundant and luxuriant during pregnancy due to hormonal changes, only to shed months after childbirth?

Do you think you can encompass all aspects of pregnancies? Test your knowledge with this quiz to see if you can deliver! Remember to sign in to add your name to the leaderboard; clues are available by clicking the yellow button. Best of luck!
