Female Reproductive System
How do these cells meet?Ovum are produced and stored in the woman’s
ovary
Around the middle of each menstrual cycle, one ovum is released during ovulation
Female Reproductive SystemWhen the egg is released, it travels towards
the fallopian tubes
These are two hollow tubes that extend from the right and left sides of the uterus
Female Reproductive SystemThe uterus is the organ in which the baby
develops and is protected until birth
One end of each fallopian tube is connected to the uterus
Female Reproductive SysteOnce inside the fallopian tube, the ovum
moves very slowly.
Here, the ovum is ready and available to be joined by a sperm
ConceptionSemen, a liquid which contains over 300
million sperm, inters the body during intercourse.
These sperm begin a journey to the ovum that lasts only minutes
Sperm TravelMany sperm do not survive, only 300-500
reach the fallopian tube
Sperm and Egg MeetThe sperm approach the ovum and try and
break through the surface
Sperm and Egg MeetOnly one sperm successfully enters. Once
accepted, no other sperm can enter the ovum.
ImplantationConception has occurred, and the zygote
forms
