A female egg cell can be fertilized by a sperm cell during ovulation, typically about two weeks before the next expected period. After fertilization, the fertilized egg will develop into a fetus over the course of about 38 weeks, culminating in childbirth.
The answer to this question is quite obvious, when sperm come into contact with other sperm they battle, much like Pokemon do. The spern that has the highest HP and attributes is often the victor, but depending on what moves you choose to teach your sperm, it may be able to defeat more powerful and higher level sperm.Also, when exposed to the egg, the sperm evolves into what is known as an 'embryo'. The embryo is even more powerful and begins to grow at a much more rapid rate and become stronger. After 8 weeks, the embryo then evolves into the 'fetus. The fetus is the strogest evolved form of the sperm as it remains in a woman's womb. The growth in the womb (via fertilization of the egg) is vital in the evolution of your sperm. Without it, you just have two underdeveloped species fighting each other ina puddle of white goo.

A zygote is formed when a sperm cell fertilizes an egg cell. It is a single cell that later divides and develops into an embryo. An embryo is the early stage of a developing organism, typically from around 2 weeks to 8 weeks after fertilization. A fetus is the later stage of prenatal development, usually starting around 8 weeks after fertilization until birth.
Sperm Cells are gametes or sex cells. They only have 23 chromosomes in humans & are 1 of 2 gametes that when joined form a zygote, a fertilized oocyte. They are used to reproduce. Sperm are not alive & only become living when 1 fertilizes an egg. Bacteria are living organisms that reproduce through binary fission, a form of asexual reproduction. Bacteria can live for weeks in contrast Sperm become useless with in a few minutes. The primary function of Bacteria is to reproduce, while the primary function of Sperm is to fertilize an ovum, & carry out the task of reproducing for the organism from which it originated.

An embryo becomes a fetus at around 9 weeks of development.
To become pregnant, male sperm cells must fertilize a females egg. If a male and female have sexual intercourse at the right time when the woman is ovulating, sperm might reach an egg cell, few weeks later the woman skips a period, few weeks pregnancy test... go from there. Sometimes women have sperm put in their uterus if they don't want to have sex.

For the first 8 weeks the developing human is called an embryo after that it is called a fetus.
A developing embryo becomes a fetus at around 8 weeks after fertilization. At this point, the major organ systems have started to form and the embryo takes on a more human-like appearance.

It is widely accepted that a fetus begins to feel pain around 20 weeks into pregnancy. By this time, the baby's tissues, muscles and nerves are developed. However, studies using ultrasounds have shown that a fetus reacts to stimulation in the womb. For example, neurobiologist M. Fitzgerald reported in "Neurobiology of Fetal and Neonatal Pain" (1994) that at 7.5 weeks' gestation, a fetus responds to stimuli. Around 10.5 weeks, a fetus whose mouth region is touched will bend his or her head in response, and the palms of the hands become sensitive to stroking. The rest of the body and legs become sensitive at approximately 13.5 weeks.
A zygote is formed when a sperm cell fertilizes an egg cell. It is a single cell that later divides and develops into an embryo. An embryo is the early stage of a developing organism, typically from around 2 weeks to 8 weeks after fertilization. A fetus is the later stage of prenatal development, usually starting around 8 weeks after fertilization until birth.
The fetus began as just two cells that joined and started dividing rapidly, by two weeks the cells became an embryo, placenta and umbilical cord - by the end of the first trimester (11 to 12 weeks) the fetus has all the organs in place that he or she will be born with, the genitalia are still to immature to visually detect the baby's sex but will be fully developed in just a few weeks. The baby to be has a beating heart, functioning bladder and practices breathing by inhaling the amniotic water.
