The primary male reproductive organ is the testes, responsible for producing sperm and hormones, primarily testosterone.
The prostate gland secretes a fluid that nourishes and transports sperm, contributing to the overall composition of semen, and helps to neutralize the acidity of the female reproductive tract.
Male gametes, known as sperm, have an average size of about 50 micrometers in length, including the head, midpiece, and tail.
Cowper's glands, also known as bulbourethral glands, are located at the base of the penis and are responsible for adding lubricating fluid to the semen prior to ejaculation.
Semen consists of sperm cells and fluids from the seminal vesicles, prostate gland, and Cowper's glands, including proteins, enzymes, fructose, and other nutrients.
