What are Spermatozoa?
Spermatozoa, or sperm, are male reproductive cells produced through spermatogenesis, a complex process involving cell division and maturation. Sperm are tiny, motile cells designed for fertilization.
Structure
Head: Contains genetic material (DNA) and enzymes to penetrate the egg.
Neck: Connects the head to the tail.
Tail (Flagellum): Propels the sperm forward.
Midpiece: Provides energy for movement.
Acrosome: A cap-like structure covering the head, containing enzymes for egg penetration.
Functions
Fertilization: Sperm fuse with an egg cell (ovum) to form a zygote.
Genetic Material: Sperm carry half of the genetic material necessary for embryo development.
Motility: Sperm move through the reproductive tract to reach the egg.
Interesting Facts
- Sperm are incredibly small, measuring around 50-60 micrometers in length!
- A healthy adult male produces over 1,500 sperm per second!
- Sperm can survive inside the female reproductive tract for up to 5 days.
- The entire process of spermatogenesis, from stem cell to mature sperm, takes around 70-80 days.
