What is semen made of?

Semen is a fluid that is released during ejaculation. It is composed of various substances such as seminal vesicle fluid, prostate fluid, sperm cells, and bulbourethral gland fluid. The seminal vesicle fluid makes up the majority of the semen volume and contains fructose, enzymes, and prostaglandins. The prostate fluid contains substances such as enzymes, citrate, and zinc. The sperm cells are produced in the testicles and make up only a small percentage of the semen volume. The bulbourethral gland fluid is released earlier during arousal and helps to neutralize any acidic urine remaining in the urethra. Together, these substances create the unique composition of semen.
