Question

Trace the path of a sperm from the time it is produced until it fuses with the ovum.

Answer 1

Male gametes:

• The sperm is the male reproductive cell produced in the testes.
• It has to pass through a series of structures from the testes in order to be ejaculated.

Path of sperm in male reproductive system:

• The sperm's journey begins in the testis. Sperm develops as tiny round cells in seminiferous tubules or testicles.
• Then it is passed through an efferent tubule a passage for premature sperms. Hormones from testicles and pituitary glands help the sperm to mature.
• They further travel to the epididymis and develop for several weeks.
• Then it migrates to vas deferens.
• Then travels to the seminal gland to get nourished by seminal fluid.
• It travels to the prostate gland and is mixed with prostate fluids.
• It then passes through the urethra before ejaculation.
• The fluid contains nutrients that protect the sperm cells during their journey.
