The sperm complete their development in the epididymis.
No sperm isn't impacting your muscle development.
The gametes, or "sex cells" - the sperm and ovum (egg) - become the fertilized egg (zygote) when they fuse.
The zygote is formed in the fallopian tube after fertilization of the egg by sperm. It is the initial stage of embryonic development where the genetic material from both the egg and sperm combine to form a single cell with a complete set of chromosomes.
The term that refers to an egg that has been fertilized by a sperm is "zygote." A zygote is the initial cell formed when a sperm cell successfully merges with an egg cell, marking the beginning of embryonic development. It contains a complete set of genetic material, half from the mother and half from the father.

the role of testes are to make sperm.
The cell formed by the sperm and the ovum is called a zygote. It is the earliest stage of human development and contains the complete set of genetic information from both parents. The zygote then undergoes cell division to form an embryo, which eventually develops into a fetus.
Around your mid 12. During Puberty a boy will start to produce sperm.
Prenatal development actually begins when the first initial cells divide. Development continues daily until the baby is born. There are differing opinions about this and it is somewhat subject to debate.
Sperm begin development in the seminiferous tubules of the testes, where spermatogenesis occurs. They then mature in the epididymis, a coiled tube located on the back of each testicle.
Sperm itself does not directly contribute to fetal development, but it plays a crucial role in the process of conception. When a sperm fertilizes an egg, it combines genetic material from both parents, leading to the formation of a zygote. This zygote then undergoes multiple divisions and developments, eventually forming a fetus. The health and quality of the sperm can impact the success of fertilization and the initial stages of embryo development.
At the end of meiosis, there are four sperm cells.
