cum

Semen is the male reproductive fluid that is ejaculated from the urethra during sexual climax. It is a complex mixture that contains sperm cells and various secretions from the male reproductive tract, including fluids produced by the seminal vesicles, prostate gland, and bulbourethral glands. The term cum is a colloquial or slang word for semen and is commonly used in informal speech.

Composition and production: Sperm are produced in the testes within the seminiferous tubules and mature in the epididymis. During ejaculation, mature sperm mix with seminal fluid to form semen. The seminal vesicles contribute a sugar-rich fluid that provides energy for sperm, the prostate adds enzymes and minerals that help semen coagulate and subsequently liquefy, and the bulbourethral glands provide a small amount of mucus-like fluid. Typical semen volume is about 2 to 5 milliliters per ejaculation, with sperm concentration ranging from tens of millions to over a hundred million sperm per milliliter. Semen is usually slightly alkaline, helping to neutralize vaginal acidity.

Function and health context: The primary function of semen is to transport and support viable sperm during fertilization. Sperm may remain viable for varying durations within the female reproductive tract, with fertility influenced by semen quality. Medical assessments, such as semen analysis, measure factors including volume, sperm concentration, motility, and morphology to evaluate male fertility or health. Variations in semen characteristics can occur due to age, health, hydration, lifestyle, medications, or infections. Donor screening and fertility advice are common contexts in which semen-related information is discussed.
