The Sperm and the Egg

The Sperm and the Egg
The reproductive system is responsible for the creation of new life. Humans have sexual
intercourse and reproduce.. This means that a male and female come together to form a new
There is a lot of different processes that it takes for sperm and an egg to fertilize. The life span of

a female’s egg typically is about 24 hours. The life span of sperm is about 72 hours. The sperm

may not be active but can still be flowing throughout the body after the 72 hour period time frame.

  Egg fertilization starts by a mature being released from the follicle, and continues with the

appearance of two pronuclei after sperm entry into the body. The egg or oocyte transports from

the moment of expulsion for the follicle to enter into the fallopian tube. It takes approximately 5

days for the egg to travel through the body until reaching the uterine, this is then called the

blastocyst. The egg transports in the body before and after a menstrual cycle. The egg

transplants during the pre-fertilization stage and after the ovulating cycle. A number of events

happen with the sperm before successful fertilization. The first is the amount of fertile mature

spermatozoa being in the penis to ejaculate, next the sperm must be able to enter the cervical

passage into the uterus of the female. The sperm must also have a good progressive motion

when ejaculated to get threw the cervic’s mucus into the uterine and fallopian tubes to make it to

the egg in order for them to bind together and fertilize. This is called capacitation. The

spermmust spend enough time in the tubes and tracts of the female in order to have the ability to

fertilize. Capacitation happens when the sperm passes through the cervical mucus.   When sperm

and an egg combine it creates and causes an opening of channels and then result in a acrosome

reaction. As a result of the prior acrosome reaction, new sperm membrane proteins become
