Answer:

Primary Sex Organs


Testes (Testicles): The testes are considered the primary sex organs in males. Spermatogenesis: Production of sperms (male gametes). They produce testosterone, which regulates male secondary sexual characteristics.

Secondary Sex Organs

These are the structures that support sperm production, transport, and maturation. They do not produce gametes but are essential for reproduction. Seminiferous Tubules: Located inside the testes; they are the site of sperm production. Scrotum: A sac that holds and protects the testes while maintaining an optimal temperature for sperm production. Epididymis: A long, coiled tube attached to the testes where sperm matures and is stored. Vas Deferens: A duct that transports mature sperm from the epididymis to the ejaculatory ducts. Ejaculatory Ducts: Tubes that transport sperm to the urethra during ejaculation. Urethra: A common passage for semen and urine, leading to the penis. Penis: The external organ that delivers semen into the female reproductive tract during intercourse.

Accessory Glands

These glands produce fluids that nourish and protect sperm, making up the bulk of semen.
Seminal Vesicles: Secrete a fluid rich in fructose, which provides energy for sperm motility.
Prostate Gland: Produces an alkaline fluid that neutralizes the acidic environment of the female reproductive tract.  Cowper’s Gland (Bulbourethral Gland): Secretes a mucus-like fluid that lubricates and neutralizes acidic urine in the urethra. Semen: The fluid that carries sperm, composed of secretions from all accessory glands.
