Sperm:

Sperm are male reproductive cells (gametes).

They are produced in the testes through spermatogenesis.

A mature sperm consists of a head (nucleus with genetic material), midpiece (mitochondria for energy), and tail (for motility).

Sperm are specialized for fertilization and have whip-like motility.

Millions of sperm are produced daily throughout a man’s life.

Fertilization occurs when sperm penetrate the egg.

Sperm carry 23 chromosomes, contributing to the embryo’s genetic material.

Hormones like FSH, LH, and testosterone regulate spermatogenesis.

Sperm count and quality can vary among individuals.
