This is the start of an ectopic pregnancy, that is, one that begins anywhere in the body except the uterus. When an embryo starts to grow in the fallopian tube, it quickly runs out of room to expand. At that point, the tube is in danger of rupturing and the mother's life is at risk. Surgery is necessary to prevent an ectopic pregancy from becoming fatal; such a pregancy can never be brought to term.

the sperm will die
For energy so it can get to the fallopian tubes to be fertilized - ie. to move and stay alive.

Sperm cells are zygotes (specialised cells with only 23 chromosomes).
Sperm cells require more mitochondria because it takes a lot of energy to swim up to the Fallopian tube whereas egg cells get moved by the current the ciliated epithelium lining the tube create.
What is the mitochondria?Right, it's the powerhouse of the cell! Why would these cells need more power than other cells? Perhaps because they have to do more work than some of the other cells - doesn't that sound reasonable? Sperm have to swim all the way to the Fallopian tubes. Muscles have to twitch and nerves have to conduct electric current.
In humans, sperm and egg meet in the Fallopian tubes. The egg continues to move to the uterus. If the egg was fertilized, it will stay in the uterus and grow.
The move in such as way as to propell individual cells such as sperm cells.

Healthy Sperm cells tend to move in a "forward" motion, thus directly moving towards the mature and released eggs.
Egg cell begin in the ovaries, and then move through the fallopian tubes to the uterus.
